PAMI operates two environmental chambers at its Humboldt station that can generate extreme temperatures ranging from -50º C to + 60º C for various tests. The chambers can be used for a number of tests including engine cold starts, vehicle heating/air conditioning, defroster, reduced temperature component operation, and calibration of temperature sensitive equipment.
- Dimensions: 16.1m long x 5.7m wide x 5.5m high with a large 4.3m wide x 4.9m high door.
- Mechanical specifications: Multi-stage refrigeration systems capable of bringing the room to -50°C and heating equipment capable of raising room temperature to +40°C. Different operating modes available depending upon the heat load generated by the test article.
- Capacity: Can accommodate vehicles such as commercial buses, ambulances, armored personnel carriers, or other large industrial equipment. 2.4 m extension available allowing a working length of 18.5 m.
- Controls: Computerized control of chamber temperature and humidity including programmable setpoints with scheduled ramping.
|Operating Mode||Typical Use||Extreme Temperature||Lowest Temperature with Heat Load (TBD)|
