For Performance, Reliability and Value, Solaronics High Intensity Heaters Provide Energy Efficient Total Building Heating Solutions.

Solaronics gas fired infra-red K-Series heaters are designed to save fuel in manufacturing facilities, warehouses, airports, hangars and other buildings. They are especially suited in spaces with high negative or positive pressures. A wide range of BTUH inputs enables the specifier to select the best heater for a particular application, whether a modern, low-ceiling, well-insulated building or an older, poorly insulated one with high bays.

Solaronics gas fired infra-red K-Series heaters are available in many different input capacities.  Our CSA International Designed Certified to ANSI/CGA Standards heater capacities range from 30,000 to 200,000 BTUH and are certified for operation on Natural or Propane gas.  Four different control arrangements feature 100% safety shut-off; 120V and 25V direct spark; Millivolt operation; 25V direct spark 2-Stage; and 1/2″ EPT gas inlet.
