Why You Need a Humidistat

Humidistat and Thermometer | Safe Air Technology


When the humidity levels indoors reach and stay at an unacceptable range, you risk creating problems in your home or business. Not only do high humidity levels indoors lead to a muggy and uncomfortable environment, it can actually cause problems like peeling paint and wallpapers and mildewing furniture. Let’s not forget that high humidity creates the perfect environment for the growth of bacteria, viruses, fungi, and mold.

Lower humidity levels can be equally destructive. Too little humidity indoors can make the air uncomfortably dry and cause you to experience dry skin, sinus infections, allergies, and even sore throats. Regulating the humidity level indoors isn’t always easy, which is why a humidistat is an excellent investment.

What a Humidistat is and How it Works

A humidistat (also known as a humidistat controller) automatically monitors and maintains the moisture level in the air with a sensing element composed of a flat plate fitted with two metal conductors that cause an electrical resistance based on the amount of humidity in the air. The amplifier then measures the resistance, and based on the resistance measured the humidistat will turn on the humidifier if the air is too dry and turn off the humidifier once the optimal level is achieved. Dehumidifiers and portable humidifiers usually come with an attached humidistat that ensures that you don’t over-dehumidify or humidify the room. 

Thermostat/Humidistat Combo

In whole-house systems, dehumidifiers or humidifiers are connected to the central HVAC system. Humidistats can also be wired into your thermostat to run the air conditioner to regulate the humidity level independently of the temperature. 

Using the thermostat and humidistat combo conveniently helps maintain the desired humidity level without the need to run the HVAC system more than necessary. If the humidity levels are high, the humidistat will continue running the air conditioner until the humidity reaches optimal levels. If the temperature is high, but the humidity is low, the humidistat won’t allow the air conditioner to run.

HVAC Cleaning Checklist

As the seasons shift from Winter to Summer, it is an ideal time to take advantage of the milder temperatures by taking a look at the performance of your HVAC systems. Setting aside time to inspect your HVAC system is imperative for the HVAC’s performance level to operate at maximum efficiency. This time of year is also a smart time to install an industrial HVAC system for your establishment!

Here is a brief overview of the components that help your HVAC system run, understanding these components and their functions makes annual maintenance that much easier to complete! An HVAC system is an explosion-proof unit consisting of 9 essential components which include an Air Return, Filter, Exhaust Outlets, Ducts, Electrical Elements, Outdoor Unit, Compressor, Coils, and Blower. These components are responsible for functioning together as a team to regulate the heating, cooling, and ventilation of your home or establishment. Whether you live in a single-family home in Baton Rouge, a lakeside mansion near Hammond, or work in any kind of industrial or commercial building, you will still need a high-quality HVAC system with an explosion-proof air conditioner to regulate intense temperatures in the deep South.

Inside Components of Condensing Unit

Here is your efficient, simple, and quick HVAC maintenance check-list:

1. Filters:

We hear this word all the time when our cars or other appliances require cleaning, and your HVAC system is no exception. The purpose of the filter on an industrial HVAC system is to filtrate the air from pollutants like mold spores, dust, or any other toxic particles. Keeping your air clean is paramount for your health and the health of anyone in your establishment. It is recommended to check these filters on a quarterly basis (around 4 times a year) if your unit operates in an office building or a relatively clean environment. Alternatively, if your HVAC system operates in a higher-trafficked environment, like a restaurant or auto shop, then it is best to clean/replace your filter more frequently.

2. Clean the Outside Area:

The outdoor container housing your HVAC unit should be clean and free of debris because the debris can clog vents and block or reduce airflow. Remove any grass, mud, leaves, stickers, litter, or other distracting materials from your vents and coils. While you’re cleaning those coils, take a look at the coil’s integrity and straighten out any bent sections. If you’re cleaning a cabinet HVAC system, like a cabinet cooler, then it is a good idea to clean your cabinet with water and mild detergent.

3. Clean the Inside Area:

Similar to the outside area, the inside area of your HVAC system is equally as important to keep clean. Remember those 9 essential components that make up your HVAC system? It is a good idea to take a closer look at some of these components so your system continues cooling or heating properly. Mainly, you only need to focus your attention on the HVAC’s blower fans, evaporator coils, and control panel. At this point, you can also lubricate any moving parts of the HVAC system, such as fans.

4. Cooling System:

The refrigerant on the HVAC system is its cooling mechanism and it plays a vital role in running your HVAC unit at optimum health. Simply, you want to ensure it is capturing and releasing the proper amount of heat. For this step, it is best to hire a HVAC technician to look at the refrigerant (also known as “charge”) and to check for any leaks.

5. Calibrate:

This one is pretty simple! Test all of your system controls to make sure they are working properly. Ensure your HVAC system turns on and off without any issues, and after that it is best to calibrate all of your thermostats so they are outputting correct temperature readings.

6. Check and Clear Drain Lines:

Last, but certainly not least you should check your condensate drains. A drain’s function is to drain fluids freely, so take a moment to ensure they’re clear of obstruction. It’s not a bad idea to apply an algaecide to prevent unwanted algae growth, too!

Contact us today to order one of our explosion proof industrial grade HVAC/R systems, cabinet coolers, condensing units, window units, air handlers, or any other product. We look forward to hearing from you!

How to Cool a Warehouse During Summer

Cooling an office building vs a large industrial building requires very different approaches. With a warehouse or other large commercial building, the sheer amount of space makes it easier for warm summer air to get in and for cool air to escape. The heat generated from heavy machinery makes these temperatures rise even faster. So what can be done to beat the heat in a large building during the summertime? We’ve prepared 4 tips for making these environments a bit more comfortable:

1. Try Installing Screen Doors

Where applicable, installing screen doors is perfect when you want to open your doors on breezy days, allowing air flow into your building. Screen doors will protect your employees and products from any trespassers, bugs or birds.

2. Air Conditioners & Fans

Getting an industrial air conditioner that’s fit for your building can help keep the environment cool. With the right sized condensing units and air handler units built and installed by an expert industrial HVAC company, you can provide a comfortable indoor environment during the summer months.

Industrial fans are also an option for energy efficient, low-cost cooling. Large ceiling fans can provide some relief from rising indoor temperatures without investing in a complex AC system. However, if your ceilings are very high, then the effects of a fan won’t provide proper ventilation below near the floor, which won’t bring relief to anyone working inside.

3. Dehumidifiers

In particularly humid conditions, dehumidifiers can help get rid of warm moisture lingering in the air which will make the indoor air quality much more cool and comfortable. Consider purchasing a humidistat to monitor the fluctuating humidity levels inside your warehouse or other commercial building. 

4. Keep Doors & Gates Closed

The best way to keep cool air inside is to keep your doors and gates closed as much as possible. Continually opening doors, windows and gates will instantly allow hot air to pour inside the building with the cooler air escaping just as fast. This can cause your air conditioning system to work much harder than it needs to, which can increase energy costs for building owners.

Safe Air Technology Can Help Cool Any Building

At Safe Air Technology, we’ve provided sophisticated and explosion-proof air conditioning solutions for industrial buildings for many years. Our industry-leading HVAC engineers build custom units in-house so that you get just enough equipment for the size of your building. Contact us today for your commercial HVAC system needs!

Industrial Fan vs. Industrial Blower

explosion proof pressure blowers

If you’re looking for an airflow solution in your industrial process application, you might be curious as to the difference between an industrial fan and an industrial blower. However, your question is a trick question, because there’s actually no difference between an industrial fan or blower at all. The two products’ designs are the same.

The truth is, in industrial processes, a fan or blower is not defined by the design or style of the impeller, but rather which side of the fan offers the resistance the fan must overcome to move air from one area to another.

So what is the difference between a blower and a fan?

So there is a difference between a blower and a fan, but it’s really one of placement more than anything else:

  • an industrial induced draft fan sucks air through a system and discharges it to the atmosphere
  • a forced-draft or pressure blower sucks atmospheric air from outside and blows it through the system


In non-industrial systems, such as free-standing commercial or residential applications, there are a few other differences between fans and blowers as well.

Do I need an Industrial Fan or Industrial Blower?

Which machine you need depends on that machine’s function within the application. If the application requires lower volume and higher pressure, such as a burner, air dryer, fume or gas elimination, or others, you’ll need a forced-draft or pressure blower with volume and pressure focused at the outlet. If your application calls for other combinations of volume and pressure, you’ll probably want an induced draft fan with volume and pressure focused at the inlet.

Regardless of which you need, or if you’re unsure if you need an industrial blower or industrial fan, the experts at Safe Air Technology are here to help! We’ve been manufacturing explosion-proof blowers and fans, along with other air moving technology, for years, and we specialize in heavy industrial and offshore plants. Give us a call to discuss your specific application and what it needs today!


Why You Need a Cabinet Cooler

Safe Air Technology Cabinet Cooler
When you need to enclose electrical or other components in a cabinet to protect them from dust and debris, you run the risk of them overheating. When your components overheat, they can lose efficacy, part of their lifetimes, or even fail, costing you money in repair costs, lost revenue, or even emergency evacuations. To solve the problem of overheating electrical components, you need a cabinet cooler, which can alleviate cabinet heat without requiring a full air conditioning solution.

How Cabinet Cooling Fans Work

All cooling fans work on the principle of forced convection, which enhances natural convection – the process of heat transferring from one area to another through air movement – with fans or blowers. As cooler outside air is pushed through the system, the heat generated by the electrical equipment within the cabinet is pushed out through the exhaust vent.
A cabinet fan is an economical answer for any industrial enclosure you may have, as long as the environment is not excessively harsh, like an indoor cabinet without exposure to heavy dust or sprayed liquid. More intense environments or cooling needs may necessitate a closed-loop cooling system, like an air to air heat exchanger or enclosure air conditioner, to properly cool the cabinet.

Is Extra Cooling Required?

Not every cabinet on your property will need additional cooling. Natural convection and heat transfer through the cabinet walls might be enough to maintain the equipment at or below its specified maximum operating temperature.
To figure out if you need a cabinet cooler, you’ll need to calculate the total waste heat the equipment in your cabinet produces while operating, or its heat load. Your equipment’s specifications should list its heat load, so check that.
An example of a calculation is this: say you have a VFD with an operating efficiency of 92% at design load. That means that you’ll lose 8% of the total energy used by the drive as heat, since 100% – 92% = 8%. For, say, a 100 horsepower VFD, that works out to 8 hp of waste heat, or 5,965.6 watts. If your cabinet loses less heat than that via convection and conduction, you’ll need a cabinet cooling fan.

What is “Explosion Proof,” and how do I know if I need it?

Explosion Proof Vertical Wall Mount Package Unit

In your heavy industrial, refinery, or chemical processing plant, you still need a capable HVAC system to keep your workers and machinery cool. However, you can’t use just any HVAC system, since the environment of a plant is more hazardous than the standard house or business Louisiana. You need what’s called “explosion proof” equipment to keep your business and employees safe.

What does “explosion proof” mean?

The term “explosion proof” comes out of the National Electric Code (NEC®), first published in 1897 by the National Fire Protection Association (NFPA). That document defines a number of protection techniques for various hazardous locations, including explosion proof, dust ignition proof, dust tight, purged/pressurized, intrinsically safe, and hermetically sealed.

Each of these techniques contains a number of criteria that must be met by components installed in hazardous locations. The term “explosion proof,” specifically, refers to the unit’s ability to contain any explosion that originates within its housing, and to keep sparks from igniting any vapors, dust, or other particles that are in the air around the unit. It actually doesn’t mean that it can withstand an explosion! It just won’t cause any fires itself.

Do I need an explosion proof HVAC?

Each of the protection techniques laid out by the NEC® is permitted only in specific applications. Explosion proof machinery is approved for use in Class I, Division 1 or 2 locations, so if your plant or building is in a higher class, you might need other equipment. Often, if your building is in a lower class, an explosion proof unit will be acceptable. Products listed for a higher classification often surpass the requirements of lower-classified areas.

If you’re not sure whether you need an explosion proof unit or not for your HVAC needs, the helpful people at Safe Air Technology are happy to answer your HVAC questions! Give us a call any time to describe your needs and we’ll be happy to help. We know what we’re doing and what you will need!

Where can I buy an explosion proof system?

What Does an Air Handler Unit Do?

large air handler unit

Your commercial HVAC system is made up of a number of interconnected sub-systems and parts. One of the most important components of your HVAC system is called the Air Handler Unit, or AHU. The AHU is the internal partner to the Condensing Unit, which is the big metal box outside your business or on the roof with the fan. Here’s how they work together to cool your home and business.

Basically, an HVAC system works to shift heat from inside your building to the outside. The first law of thermodynamics states that heat energy can neither be created nor destroyed; rather, it must be moved outside, where it can dissipate into the air. 

That’s why a commercial HVAC system has components on both the inside and outside of your building: the inside Air Handler Unit pulls heat from the air as it’s forced through the ducts and transfers it to the refrigerant, a special chemical which can absorb and release heat effectively. The now hot refrigerant, in gaseous form, travels through a refrigerant line to the Condensing Unit, which allows the refrigerant to radiate its heat to the outside air, condensing into a liquid in the process. Then, the refrigerant cycles back inside to get heated again.

Air Handler Anatomy

Air filter

Before the air in your building enters the Air Handler Unit, it needs to be cleaned to remove contaminants that can gum up the works. The air filter, which sits between the fan and intake ducting, does this important job.

Evaporator Coils

Once through the filter, the air passes over the evaporate (or indoor) coils. These coils contain refrigerant gas, which absorbs the extra heat latent in the air and cools it. If the Air Handler is the heart of your interior HVAC system, this is the heart of your Air Handler.


After the air is cooled (or “conditioned,” as in “air conditioner”), the blower fan within the Air Handler circulates it out of the Air Handler and into the ductwork, whence it is distributed throughout your office, warehouse, or factory as cool, conditioned air.

Why is an Air Handler Unit important?

The AHU, when coupled with the outdoor Condenser Unit, is the part of your HVAC unit that actually serves to cool the air circulating through your building. If the AHU doesn’t exist or fails, your commercial building basically just has an expensive fan system blowing tepid air around. That’s why regular maintenance and upkeep of your HVAC system is vitally important to the continued functioning of the system, and indirectly the functioning of your business as a whole.

Modern HVAC systems do more than cool the air. They also filter the air of contaminants like common allergens, air-borne pathogens, and toxins, keeping the air quality in your business high. A well-functioning HVAC system is also more efficient, which saves you money month-to-month in your utility bills.

The AHU helps keep the entire process of capturing excess heat from inside your building and circulating it outside energy efficient and effective. In addition, AHUs are highly important to the safety of your building. 

Irregular circulation within your HVAC system can cause frost that can damage equipment, leading to excessive condensation inside the building. Extra liquid can pool on the floor, causing slippage, or can short important electrical equipment. A properly working HVAC system requires a floor drain or condensation box to keep everyone who works for you safe.

The Takeaway

Unless you’re an HVAC technician, you probably only think about your HVAC system when it fails. However, a properly-working HVAC system is key to keeping the temperature inside your building safely regulated, which keeps your employees happy and healthy, and saves you money on your utility bills. Make sure to keep your entire HVAC system, especially the Air Handler Unit, properly serviced and cleaned.

You need a well-designed Air Handler Unit to help your HVAC system perform optimally. At Safe Air Technology, our expert HVAC engineers can design and build certified explosion-proof Air Handlers for your industrial needs. We can even customize your AHU to fit the size and shape of your operation. Contact us today to get started selecting or customizing an explosion-proof Air Handler today.

What are Condensing Units for?

A condenser unit is an essential part of any HVAC system. To put it shortly, the condenser unit releases superheated air that is generated during the air circulation process. How you get superheated air while cooling your building can get a bit complex but knowing the basic parts of a condenser unit and thinking of air heating and cooling as a circular motion makes it much easier to understand.

Condenser Anatomy


Condensing Unit

Condenser box – Most of us recognize this as the loud box behind a house or building that controls the AC. The inside condenser walls are made up of coils that circulate very hot refrigerant (more on this below), releasing excess heat.

Compressor – This is located inside of the condenser unit and is considered the heart of the HVAC system. Compressors pump refrigerant in a closed loop of cold vapor to hot liquid and so on.

Fan – Located at the top of the condenser, the fan helps release excess heat built up inside the condenser coils.

The Takeaway

We know condenser units aren’t particularly attractive, but they’re the key to keeping the temperature inside of your building safely regulated, saving you money on utility bills, maintenance and equipment in the long run. Keep it clear of debris and other obstructions to keep your HVAC system in top shape for years to come.

At Safe Air Technology, our expert HVAC engineers design and build fully certified commercial-grade condensing units. We can even customize the right size condensing unit for your building. Give us a call to get started on finding or building the right condenser unit for your business.
