Industrial Air Curtain Line Prevents Doorway Energy Losses

Berner0106

Berner International Corp. has introduced the HL Series line of air curtains for hazardous industrial environments. The HL Series was designed for petroleum refineries, food processing and pharmaceutical plants, chemical facilities as well as compressed natural gas bus garages.

The product line restricts energy losses and the infiltration of fumes, airborne contaminants and flying insects by separating indoor and outdoor environments at open industrial doorways. The HL Series construction is based on explosion-proof motors, spark-resistant fans, HL electrical components and construction and other precautions required by ANSI/NFPA-70 National Electrical Code regulations. Standard construction complies with Class I, Division 1 and 2, Groups C and D for gases; and Class II, Division 1 and 2, Groups F and G for dust. Optional construction is available for Groups A and B.

HL Series units are factory assembled in single-length units from 3-feet to 16-feet-long cabinets that don't require intermediate installation supports. The product line also features Berner's proprietary explosion-proof motors ranging from ½-hp to 15-hp and heavy-duty blowers to protect doorway heights of six to 20-feet-high. Optional steam or hot water coils with a 130°F to 180°F temperature range are available with custom-constructed ANSI/NFPA-70-compliant aluminum chassis.
