Mobile and stationary gas analyzers and systems
Air and exhaust air analysis
The stationary gas analyzers and systems of the COMBIMASS® series are used for the analysis of exhaust air in e.g. sewage treatment plants or for monitoring the air in double-walled membrane gas storage tanks.
In both of these applications the concentrations of methane and hydrogen sulphide to be measured can be extremely low. Consequently, no standard NDIR measuring cell can be used such as in the biogas sector.
Additionally, when monitoring the air of the membrane roofs, low concentrations of methane is already present in the atmosphere in the intake area, which can change depending on the weather conditions and passing agricultural vehicles. Therefore only the analysis of the supporting air alone would lead to an incorrect measured value. The difference between the air drawn in and the air flowing out must be measured and evaluated in order to determine whether the permeability of the membrane has deteriorated or even ruptured over the course of operation.
Long-term monitoring can extend the service life of the membrane roofs (TRAS 120) and detect losses of methane at an early stage in the case of damage. Therefore, long-term monitoring not only improves operational safety but also significantly reduces the operating costs of the entire plant.
COMBIMASS® GA-s hybrid premium air monitoring
Modular gas analyzer station
The COMBIMASS® GA-s hybrid premium air monitoring analyzer station consists of a ventilated cabinet for the cyclic analysis of the air of 1 up to 4 fermenters for indoor installation with an integrated display and flexible measuring program. The gas modules have an integrated maintenance diagnosis whereby the wear is signaled by the traffic light colours. Transmission of data and alarms is possible via various bus systems. Additionally, the warning lamp rounds off the station for a simple and safe operation.
COMBIMASS® GA-s hybrid eco air monitoring
Basic modular gas analyzer station
The basic, modular COMBIMASS® GA-s hybrid eco air monitoring analyzer station consists of a cabinet for analysis of the supporting air from 1 or 2 fermenters. It is a station for indoor installation with a fixed measuring programme. Data and alarm transmission as well as a warning light complete the station for a safe operation
