Biogas Blowers & Compressors

EVEREST Biogas Blowers | Compressors based on Positive Displacement Air Blower principle, have been specially developed for pumping of Biogas. These are generally used in biogas lines to boost the gas pressure to meet the burner input demand. These are generally vertical flow type in construction, i.e. suction top & discharge at bottom, so as to prevent any accumulation of corrosive matter inside the casing. Since they operate in closed loop, suction and discharge silencers are generally not required. Special material of construction, lubrication and sealing arrangements make them ideal choice for Biogas boosting applications. Provision for a vacuum switch is provided at the inlet of the blower, so that incase the biogas generation falls below the pumping speed of the blower, the blower trips and this prevents vacuum overloading. Similarly provision for a pressure switch is provided on the discharge line to safeguard the blower against excessive discharge pressures.

Special blowers, capable of handling different gases, are also available at Everest. Material of construction and constructional details vary to meet different gas requirements. For inflammable and toxic gases, leak tightness is ensured. Basic designs are modified, depending upon the nature of gas to be handled and customers' requirements. Water jet injection cooling can also be provided to keep the gas temperatures low.
