2G. Technical Specifications patruus 160 (160 kW) Natural Gas 2G. Combined Heat & Power. 2G-KWK-160EG_60Hz/480V Illustration: may differ from specified module Compact CHP ready for connection, mainly Integrated heat exchanger basket, mainly consisting of consisting of - serially manufactured Industrial-Gas-Otto-engine - air-cooled synchronous generator - expansion tank in motor circuit - relief valve in motor circuit and heater circuit - exhaust heat exchanger integrated in primary - filling valves, cleanout valves and exhaust valves - plate heat exchanger cooling circuit - 3-Way catalyst integrated in exhaust heat exchanger - oil reservoir with automatic oil refilling - pumps for motor circuit and heater circuit - 3-way mixing valve for return temperature increase - control cabinet with programmable controller and operating unit - gas train Water and gas connections are executed with compensators. All water-side connections are directed upwards above the heat exchanger basket. Motor and generator are connected through a pluggable elastic metal-plastics coupler to compensate radial offset, axial offset or angular offset. It is mounted on a framework vibration-reduction. Furthermore the framework is uncoupled through oscillation decoupling elements. The control cabinet is executed as a separate unit. All regulation and control functions as well as control elements are part of the control cabinet. Assisted by a menu-navigated touch-screen performance data and state data can be read and adjusted easily. The drive of the CHP is caused by a water-cooled Otto-Gas-Engine. It is a stationary engine designed for permanent operation. A microprocessor-controlled ignition ensures an optimal adaption of the ignition point and the ignition energy to the gas quality (methane number). The oil level control is carried out by a sight glass with oil level deficit indication, which is connected with the oil pan.
