The HLV Series infrared vacuum heating system is engineered specifically for the design parameters of the building it is required to heat. More commonly found in larger commercial and industrial applications, these systems offer potential operating benefits that are not easily obtainable with traditional infrared tube heaters.An engineered vacuum system emits low intensity infrared heat just like any other type of tubular heater. What makes these systems unique is the method in which they operate as well as their expanded operational boundaries. The operational objective of a vacuum system is to simply move hot gases from the burner(s) to the pump. This movement heats the emitter pipes, which in turn heat the building via infrared energy.The HLV Series is engineered to utilize both two stage and condensing technology, offering optimal operating efficiencies and fuel savings.
