Gas Burner ( Option )
Amrta rooftop packaged unit 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.
The gas heating modular use a safe and reliable atmospheric gas burner made of aluminized steel tube heat exchanger designed to offer maximum heat transfer and 92% efficiency (PCI%). It runs with natural gas in an operating range of 1.3-2.6KPa. The standard gas module offers 2 stages of control which helps in improving space comfort by avoiding large supply air temperature deviations. The airflow rate in the burner is controlled as the gas flow is being reduced maintaining the burner to its highest efficiency level.
S: 30kW
M: 50kW
L:100kW
3 modules are available, which can provide separately 30kW, 50kW and 100kW heating capacity in standard working condition according to your different heating requirements. Where more capacity is required a modulating version is available with flexible combination. For safety reasons, the rooftop packaged unit with gas burner can`t be installed inside a technical room.
