Most popular in the industry Suitable for most standard HVAC ducted systems Heating capacities from 0.5 to 1000kW (larger loads also available) Up to 40kW per sq.ft Integrated HEC controller Patented EAS (Electronic Airflow Sensors)

Open Coil Elements Options
4Grade C NiCr60 (60% Nickel and 16% Chrome) 4Grade A NiCr80 (80% Nickel and 20% Chrome)

Recommendations
For applications in a humid environment, we recommend the optional NiCr 80 (grade A) elements. They are composed of 80% Nickel and 20% Chrome (does not contain iron). This will allow a maximum operating temperature of 2,100o F (1,150o C) and installation where condensation may be present in the air duct.
