Air Innovations can control for a broad range of temperature and humidity conditions. We control environments from 0°F to 100°F (-18°C and 38°C) with tolerances from plus or minus a few degrees to ±0.01°C. We also control conditions from trace moisture (subzero dewpoint) to 90% RH ±0.5%.

Our environmental control equipment has be designed and tested to operate in ambient conditions from -40°F to 130°F (-40°C and 54°C) and up to 100% humidity.

Air Innovations designs for innovation and tests for precision in all sorts of environments:

  • Constrained sizes or configurations
  • Explosion-proof HVAC
  • Mobile environmental control units
  • High filtration ECUs (HEPA, ULPA or molecular)
  • Typical or specialty refrigerants
  • Diverse testing protocols (AHAM, AHRI,ASHRAE, CE, L, CC)
  • Positive or negative pressure environments
  • Stainless-steel construction
  • Ruggedized / military grade HVAC systems
  • Integrated humidification (immersed element or ultrasonic)

Absolutely! Air Innovations has partnered with many customers to create integrated cooling systems. We have integrated cooling systems into applications as diverse as blood analyzers (biomedical), x-ray baggage scanners (security), large-scale centrifuges (oil & gas), semiconductor tools, and even office desks. Find out more about our custom environmental control capabilities.

Air Innovations works with all Clean Room classifications (ISO 1 to ISO 9). In fact, Air Innovations has an entire brand dedicated to Clean Room Environmental Control and air conditioning. We specialize in designing and manufacturing customized modular HVAC systems from ½-ton to 25-ton unit capacities. You can learn more at or contact us concerning your project today.

We work with all sizes of critical environments from small cabinets to full size rooms requiring up to 10,000 CFM.

Air Innovations has worked with customers locating ECUs in a variety of places, depending on their unique requirements and constraints. ECUs can be freestanding in a dedicated mechanical space, ceiling mounted, integrated into a larger system, or designed as mobile HVAC systems, depending on the situation.

The heat load determines the size of the environmental control system required to cool the space. Different heat loads may require a solution as small as a ¼-ton ECU to a multi-system 25-ton capacity approach.
