HL SERIES:

STATE OF THE ART, TWO STAGE, LOW INTENSITY, INFRA-RED TUBE HEATER

THE HL SERIES IS THE FIRST INFRA-RED HEATER IN THE INDUSTRY WITH TWO STAGE HEATING CAPABILITIES.
Patented Design

The HL Series is the latest advancement in infra-red technology. It is capable of operating in either a high fire mode (100% of rated input) or in a low fire mode (70% of rated input). Its' mode is dictated by momentary environmental demands. The system is, in effect, responding to your building's needs, giving you the most economical and efficient heat possible. This will result in significant fuel savings of at least 12% (based on independent study) over any other type of infra-red heater. These heaters are available in BTU/H inputs of 50,000 to 200,000, Natural or L.P. gas, and emitter lengths of 20 to 70 feet.
