The Espar’s Fuel Operated HYDRONIC M-II Coolant Heaters
Espar’s coolant heaters work independently of the engine and thus offer a double plus: pre-heating the vehicle’s passenger compartment and the engine.

The heaters are integrated in the cooling system of the engine. The thermal energy gained is then distributed through the vehicle’s own heat exchanger as forced hot air and this heats the interior of the vehicle via existing air vents. The engine is warmed up with the residual heat in the cooling water.

Practical controls – such as a digital Espar timer or key fobs – make for ideal and pre-heated engines and compartment space.

This series of heaters is powerful, compact and light weight but rugged in design making it ideal for providing engine, fuel and hydraulic pre-heat for off-road equipment. It is also ideal for providing both engine and supplemental cabin heat for buses and
boats.

SIMPLE, EFFICIENT & CONVENIENT!
The M series heaters have automatic altitude compensation and multiple operating speeds for reduced amp draw. The coolant heaters can be boxed for protection against the elements. These units are bio-diesel compatible and are ideal for off-road and non-mobile equipment as well as school buses.

HYDRONIC coolant heaters can preheat the engine, indirectly heat the cab and provide auxiliary heat for fuel and hydraulic tanks and other service fluids. The M-II represents the latest in fuel operated coolant heater technology. The M-II series of heaters is available in one size with the option of four power levels

● Output control in small increments (1.2 – 12 kW)
● Ceramic glow pin
● Electrically commuted motors for combustion air, fan and water pump
● Heater can be mounted in different positions and angles for installation flexibility
● Biodiesel-compatible (8 kW version) up to 100%
● EPA verified/CARB compliant for use anywhere in North America
