Psychrometric Testing Facility


Psychrometric Testing Facility

Air Innovations’ psychrometric facility is a two-chamber laboratory that tests the safety, reliability and performance of our products in a controlled environment. The two rooms—dedicated for indoor and outdoor conditions—mimic specifications under which products will actually operate, many of which are very tight temperature and humidity tolerances.

The facility is used for a wide variety of products that we design and build including products intended for pharmaceutical, semiconductor, medical, research and other industries. We also test the components used in the company’s air- and water-cooled packaged, through-the-wall, and split systems as well as competitors’ performance parameters.

Contract Testing:

The lab is available for contract testing (though not as a “certified” lab). Contact us about your requirements today. Just let us know what you want tested and the data you would like generated, and we will let you know whether we can accommodate your request with our lab and a test engineer.

Technical Information:

The 2880 cubic foot facility tests temperatures between 0°F and 120°F (-17°C and 48°C). Humidity is created by an ionic-bed electric steam generator rated at 45 pounds/hour (20.4 kg/hr), controlling to ±2.5% relative humidity. Cooling capacity is up to 33,000 BTUH (9.67 kW) per room, while heating capacity varies from 14,000 BTUH (4.34 kW) in the indoor room and 130,000 BTUH (38 kW) in the outdoor room. Each room operates 2100 CFM (3567 cubic meters/hr) of continuously re-circulating air. Airflow measurements (up to 800 CFM) and unit-under-test leaving air properties for dry bulb/wet bulb are collected via a code tester or standard airflow hood. Automated data acquisition and control reduces data collection time.

The facility can test 60 Hz products between 115 V and 277 V (1 phase) and 208 V to 460 V, 3 phase. Products at 50 Hz / 230 V (3 phase) can be tested too. The facility meets all major national and international standards for safety and performance such as: Association of Home Appliance Manufacturers; American Society of Heating, Refrigeration and Air Conditioning Engineers; Air Conditioning, Heating and Refrigeration Institute; CE Mark; and, Underwriters’ Laboratories.
