Heating Possibilities
Electric heater
The electric heater comprises of shielded resistance heaters, which are smooth stainless steel tubes 6 W/cm2 capacity. High temperature limit control offers overload protection and is set to 90°C and located at less than 150mm after electric heaters. This is provided as a standard feature on the electric heater, with the electric power supply cables made of reticulated silicon rubber, resistant to temperatures up to 200°C. For any rooftop unit size, three sizes of electric heater are
available, S (standard), M (Medium) and H (high).
Hot water coil
Hot water coils offer fully modulating control through the use of a 3 way valve. The hot water coil, connections and valves are all tested at pressure of 15 bars.
Frost protection is provided by forcing the opening the 3 way valve when supply temperature from hot water coil falls below 8°C and by stopping the outdoor fan when that supply temperature falls below 6°C. In addition to that, the 3 way valve is also opened at 10% value if the outdoor temperature falls below an adjustable value.
Hot water coils are always factory fitted, wired and fully tested, prior to shipment.
