According to the manufacturer, the heater is designed to resist wet, corrosive environments typically found at car washes, outdoor loading docks and platforms, maintenance facilities, and warehouses.
Supplied completely assembled and factory tested prior to shipment, the company said the heater's critical system components include a stainless steel watertight enclosure with all gas and electrical controls prewired and sealed; stainless steel casing with reinforcing angle rings; and stainless steel burner baffle - all designed to ensure safe and dependable operation and long life.
According to the company, the Doorjet Heater produces a high velocity "jet" of heated air that is directed automatically toward outside bay doors as they open. The heat surge is designed to temper the inrush of cold air, keeping employees working in the area comfortable. Also, energy is saved as a building's heating system can maintain its normal operation without having to compensate for sudden cold air bursts, said the company.
"Whether it's a car wash with one or two doors, a small factory, a warehouse, or distribution center with high volumes of shipping and receiving cycles, the dependable Doorjet Heater operates without employee intervention," said Tom Lester, Solaronics' vice president of sales and marketing. "As the outside door is raised, a door limit trip switch automatically activates the fan and burner, instantly producing a â€˜jet' of hot air - without a warm-up period. When the door closes, the heater safely shuts down."
Doorjet Heaters may be mounted vertically to direct heat straight down for roll-up or straight-lift doors; horizontal or angled placement for conventional lift doors. The company noted that the heaters are easily installed, with connections to electrical source, gas supply, and door limit switch. While designed to operate economically on natural gas, the heater can also be specified for other gaseous fuels. Models are available with input ratings from 550,000 to 950,000 Btuh to accommodate most building requirements. A single Doorjet Heater will handle typical door openings of up to 12 feet by 12 feet, said the company.
