Air Conditioner

Closed Loop System: Can maintain a Type 3R, 12, 4 or 4X rating and can create an environment cooler than ambient. This is an ideal type of cooling which creates a more reliable system and improves equipment life cycle. A typical internal temperature design point is 85-95 F. Hoffman air conditioners are designed for continuous operation in ambient environments up to 125 F or 131 F, depending on the model.

For sizing and selecting an air conditioner, refer to the Hoffman Thermal Management Catalog, or go to hoffmanonline.com to use the Thermal Management Sizing and Selection Software.
