With the constant evolution of technology, American air services, LLC, are working hard to keep you and your industry up and running. We are improving the quality of our products to meet the advanced requirements of the industry. We are proud to say that our products will encounter not only the regulations but also your expectations. While, also, to make our products long-lasting and environmentally friendly, manufacturers of industrial HVAC systems are using new refrigerants. For this purpose, they are turning towards a more efficient refrigerant known as R-410a refrigerant. R-140a needs high pressure for its working operation. Comparing to R-22, it requires a higher pressure on both the high and low sides of the cycle. For manufacturers, they were to produce the products capable of withstanding the high amount of pressure. Higher pressure assures higher efficiencies; this is because R-140a has more significant thermodynamics abilities as compared to R-22. R-140a is a mixture comprises of HFC-35 and HFC-120, which is a better mixture to transfer heat.

R-140a is an HFC (hydrofluorocarbon) is a symbol of evolution for residential and commercial industries. More importantly, it is more efficient than older HFCs. Along with environmentally friendly, it also requires a smaller compressor.

For some applications, R-140a outperformed other HFC refrigerants, especially in meager and very high ambient conditions. One thing that should be kept in sight is the comparison of the capabilities of other refrigerants with R-140a.

  • For R-134a to meet the heat transfer ability of R-140a, it requires a considerably large set of coils. Therefore, we must arrange larger cabinets to satisfy the desired requirements. R-134a is, in fact, 33% less efficient than R-140a. In simpler terms, for a capacity of 10-tons, you will need a cabinet of 15-tons, to satisfy the given condition.
  • Not a significant difference, R-407c same as R-134a can cause power reduction, but efficiency is nearly 5%. Furthermore, R-407c is quite similar in transferring heat as R-22, and they use the same elements in a complete cycle.

Modern problems require modern solutions. Each advanced application brings with itself newer challenges and room for improvements for HVAC systems. And what’s more challenging environment than offshore gas, oil, and petroleum industries. These industries have one of the most corrosive atmospheres as they deal with corrosive and hazardous chemicals in daily usage. There is no wonder that few companies are crafting HVAC systems meeting the needs of these types of industries. American Air Services, LLC, are studying the intricacies of offshore companies like these for a very long time. Now, to fulfill the needs of an offshore customer, we have some specific designs to meet the requirements of their offshore industry to make it explosion-proof. Combining minimized and corrosion resistance footprints, you can apply these options packages to our HVAC unit to better efficiency and a longer lifetime.

  • Combustible gas alarms and H2S sensors.
  • Severe duty motors of division 2 class 1, complies with IEEE 45 standards for marine duty.


With the premium floor space of the offshore industry, where can we put an extensive HVAC system? Our specially crafted units offer a variety of configurations fulfilling the needs of many arrangements. Low profile roof-mounted arrangement along with wall mounted units are quite important fulfilling height requirements along with establishing smoother airflow and increased capacity.

To completely fathom the meaning of the “explosion-proof” system, we must understand its contextual meaning and study of the organization which defined this term. In the year 1897, an organization named the National Fire Protection Association (NFPA) suggested some codes known as the National Electric Code (NEC). The National Electric Code covers a diverse range of protection practices while designing a product for the assurance of its non-hazardousness. Hermetically sealed, dust-tight, ignition proof, intrinsically safe, and pressurized. These are the set of definitions or criteria that must be met by all the components to be allowed to install.
For explosion-proof HVAC systems to meet the specified criteria, the components which can cause the explosion must be contained in an enclosure for the prevention of explosion. Therefore, explosion-proof does not mean that it would withstand an exterior explosion. Instead, the enclosure can either prevent an internal spark or protect the components of the HVAC system form having a much larger blast.

Moreover, the NEC also specified the temperature requirements of equipment, which must be met to install the system. So, it suggests that the working temperature of the motor must not be higher than the lowest combustion temperature of the dust or gases in the environment where it is implanted.
