Commercial/Industrial Air Curtain Division

Direct Gas Heated EHD

Extra High Door with Direct Gas Heat is used in stopping cold drafts from entering an extra high opening while providing warm air produced by direct gas heaters. The aire curtain pulls the air directly through the flame of the direct gas heater. The EHD DG blankets the full length and width of the door with warm air. The Extra High Door with Direct Gas will discharge a temperature of 105° F, even if the entering air temperature is 0° F. The EHD DG provides a maximum temperature rise of 105° F and can draw 100% inside air as long as the door is open. This unit is commonly used where temperature is critical to maintain. The EHD DG is recommended for doors over seventeen feet high (anything lower would require either a TDG or TSD DG). The EHD DG has top and bottom access panels to replace or service motors or blowers without lowering entire unit or bottom half of unit. All units are direct drive, which avoids misalignment of couplers and outboard bearings and eliminates periodic belt replacement. The motor/blower plate comes out as an entire piece and all parts on the outside of the unit are constructed of stainless steel.
