Product description
Rooftop packaged unit with Gas burner. The gas burner will be inside the Rooftop Packaged Cooling System if cooling capacity is very small. Otherwise, the gas burner will be outside the Rooftop Packaged Air Conditioning. Amrta rooftop units can be fitted with a gas burner. As one of the auxiliary heating devices, it allows the rooftop units to heat without running the refrigeration system or only with a part of it to achieve a high performance of energy-saving at lower ambient temperature in winter and to reduce massively the heating operating costs specially for where the natural gas is cheaper than electricity.
● Wide choice of communication interfaces

* 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 20.0°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.
