Energy efficient, cost-saving radiant heaters

HLV Series: Two-Stage, Multiple Burner Heating System

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.


  • Two-stage operation maximizes comfort levels and reduces equipment cycling, resulting in significant energy savings.
  • Systems can be designed with 1 to 6 burners ranging from 40,000 to 750,000 total BTU/h with a single vent penetration.
  • Tandem burner design allows independent combustion air for each burner.
  • Slip-fit tube exchangers with bolted tube clamps.
  • Pre-wired, spark resistant, cast aluminum vacuum pump with thermal overload.
  • Self-diagnostic circuitry and operation indicator lights.
  • Heavy-duty balancing damper.Key operational features include a 20% reduction in output when operating in low fire and stainless steel tailpipe when optional condensing operation is utilized. Infrared output is optimized with highly polished aluminum reflectors and coated aluminized radiant tubes.

Burner Control Assembly:

Tandem designed HLV Series burners range from 40,000 to 200,000 BTU/h and do not require the use of combustion air filters, since each burner draws its own fresh air for combustion.

Emitter Pipe:

4-inch O.D. 16 gauge titanium-stabilized and aluminized steel tubes treated with a highly emissive black coating offer  superior longevity and protection. 

A swaged, interlocking tube design provides a tube-on-tube overlap that helps to ensure structural integrity, ensures a tight seal, and is easier to install.

Condensing systems are fitted with corrosion resistant 304 stainless steel tailpipe insuring years of reliability.

Vacuum Pump:

Pre-wired, spark resistant, heavy-duty cast aluminum 3/4-hp, 1/2-hp or 1-hp pumps  allow for multiple high BTU burners per system.


Multi-faceted highly polished reflectors  maximize the amount of infrared energy that is directed to the floor level – where heat is needed most.


State-of-the-art pre-programmed building management control panels are available for  use as a stand-alone or overall building  management system.
