Gas Mixing System GMS 150
GMS 150 can produce precise mixtures of up to 4 different gasses. The flows of the individual
input gases are measured by thermal mass flow meters and adjusted by integrated mass flow
controllers. Before the exit connector, the gas mixture is thoroughly homogenized. The input
and output gas connectors are of Prestolok type allowing fast and secure connection to a variety
of tubes.
- The GMS 150 can be used as a stand-alone instrument or in a system with the Photobioreactors, Multi-Cultivators and FytoScopes.
- It can be controlled locally from its front panel or by software (in systems with Photobioreactor).
- The user can define the required gas mixture either by setting the flows of the individual gasses (e.g., 980 ml/min of N2 and 20 ml/min of CO2) or by setting the required relative composition of the gas mixture (2 % CO2) and the total mixture gas flow (1000 ml/min).
- The side installation requirements for the proper operation of the GMS are pressurized air supply and supply of the desired gas (CO2, N., etc.).
- Pressurized air used for the GMS must be dry and oil free. The inlet pressure should be in range of 3 – 5 bars.
