Espar Coolant or Hydronic Heaters

ATC is a proud Espar MSD providing Coolant or Hydronic Heaters to pre-heat the engine coolant and with modifications, warm the passenger compartment through the existing vehicle heating system.Espar’s Hydronic Heaters are typically tied in to the vehicles coolant system. These heaters pre-heat the engine coolant to allow for effective vehicle starting in extreme climates. With some modifications, vehicles can be configured to allow for warming the passenger compartment through the existing vehicle heating system, allowing the Hydronic heaters to pre-heat both the engine and passenger compartment.  

With the addition of a Fluid Warming system, Hydronic heaters can be used to pre-heat both hydraulic and fuel systems on heavy equipment.
