S-Series High Efficiency Space Heater Applications

The most energy efficient way to heat both new and existing buildings with large open spaces such as: warehouses, distribution centers, manufacturing & assembly plants, indoor sports facilities, automobile dealership service bays, car washes, aircraft hangars, boat storage WWTP facilities and other commercial/industrial facilities.


Enhanced Comfort with Improved Indoor Air Quality

Discharge air from the S-Series Space Heater, provides large volumes of fresh, warm air flowing throughout the building which eliminates higher ceiling temperatures and uncomfortable drafts. The S-Series Heater utilizes 100% fresh air to dilute contaminants generated within the building. This virtually eliminates air quality problems associated with infrared heaters or conventional air heating systems that just recirculate indoor air.

S-Series Blow-Thru® Space Heaters are 40% to 70% more energy efficient than all other types of indirect and direct gas-fired systems used to heat/ventilate large commercial and industrial buildings. Energy saving HVAC retrofits include replacing Boiler, Unit Heater, Air Turnover, Infrared, Make-Up Air (MUA) and Recirculation (80/20) heating systems.
