COMBIMASS® GA-s hybrid eco is a desktop analyser without graphic displays. In the basic version it has a CH4 gas module of the hybrid series with the possibility of measuring one gas stream. By means of an upgrade option, we are able to increase the measuring range to two streams for such gases as methane, oxygen and hydrogen sulphide. It is mainly used for monitoring the biogas filter upstream of the CHP engine. Choice of plastic housing or, in a more expensive version, stainless steel.

Application:

  • Monitoring of the biogas filter upstream of the CHP engine

Measuring range:

  • 1 CH4 gas module of the hybrid series with NDIR cell, operating range: 0 – 100 % v/v
  • Housing: plastic 300 x 400 x 200 mm, wall-mounted
  • Number of sampling points Standard: 1 (extendable to 2)
  • Ambient conditions: indoor installation, room ventilated and monitored for LEL, temp. + 5 to + 40°C, relative humidity <80%, in a non-corrosive environment
  • Gas properties: + 5 to + 40°C, 10 to 90% relative humidity
  • Protection class: IP22
  • Gas pump flow rate: 500 ml/min (during gas sampling)
  • Data transmission: analogue signal 4 – 20 mA

Expandable:

  • additional gas modules O2 0 – 25 % v/v or H2S 0 – 50 (200, 2 000) ppm
  • transmission via Modbus RTU
  • all connections will be prepared in stainless steel (usual use in wastewater treatment plants)
  • external 230 V AC/24 V DC power supply box (for the analyser cabinet, which operates with 24 V DC for safety reasons)
  • 1 gas cooler with DTG-GK hardware extension, a second pump and one NO valve (in addition to the NC valve upstream of the H2S module), if methane is to be analysed continuously
  • reading and sending of the analogue signal from the biogas flow meter of the COMBIMASS® series
  • heating/cooling device for external installation of the analyser
  • COMBIMASS® GA-s hybrid eco CH4
