Espar Air Heaters operate on Gasoline or Diesel fuel and are manufactured in 12 or 24 Volt models. Heat outputs range from 6000 BTU to 41,000 BTU. Applications range from bunk, cargo and cabin heat.
These air systems are compact with all heat creation and fan distribution neatly packaged within the unit. The heaters have from two to four heat levels and cycle between these levels according to the temperature desired by the user.
When the heater is turned on by the switch, thermostat or timer, a control unit signals the blower motor to draw combustion air into the heat exchanger, simultaneously fuel is drawn from the fuel tank by the heater's fuel pump and mixed with the air.
As an ignition plug ignites the fuel /air mixture, a controlled flame is established inside the sealed heat exchanger; combustion gases pass safely through the exhaust and into the atmosphere.
Clean air is drawn over the walls of the heat exchanger and circulated via the heater's fan. Flame, temperature regulating and overheat sensors are among the safety features which make these air heaters safe and dependable heating systems.
