Electric heater
The electric heater incorporates ensured deterrent radiators, which are smooth tempered steel tubes 6 W/cm2 limit. High temperature limit control offers over-trouble security and is set to 90°C and arranged at under 150mm after electric radiators. This is given as a standard segment on the electric heater, with the electric power supply interfaces made of reticulated silicon flexible, impenetrable 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 totally altering control utilizing a 3 way valve. The hot water coil, affiliations and valves are completely attempted at weight of 15 bars. Ice affirmation is given by convincing the opening the 3 way valve when nimbly temperature from hot water coil falls underneath 8°C and by stopping the external fan when that deftly temperature falls underneath 6°C. Despite that, the 3 way valve is furthermore opened at 10% worth if the external temperature falls under an adaptable worth.
Hot water coils are reliably modern office fitted, wired and totally attempted, before shipment.
Structure
Sheets and edge are delivered utilizing mixed steel made sure about with polyester powder painting to ensure total insurance from climatic administrators.
Direct improvement twists with condensate channel plate.
Hermetic compressor
High capability scroll compressor for the whole range, with built-in thermal overload cut-out and crankcase heater, mounted on rubber vibration dampers.
Ripple type acoustic insulation for compressor section, and thermal insulation for coil and fan section, low noise.
Centrifugal fan
Forward curve scroll fans for air treatment portion and axial fans for condensation section.
Front, side and underside air discharge of the treatment unit.
High external pressure, long air supply distance.
Electric board
Electric board contains breakers and contactors for compressors and fan motors, phase sequence relay and other indispensable protection devices for the main components.

* Performance values refer to the following conditions:
Cooling: room air temperature 27.0°C DB RH 50%, ambient air temperature 35°C.
Heating: room air temperature 21.0°C DB, ambient air temperature 7°C DB / 6°C WB.
** Noise level measured by adopting average value in the noise lab with background noise of 25 dB(A), at a distance of 1.5m high fan speed.
