Tri-Gas Mixer

The Tri-Gas Mixer is a digital CO2-O2 controller that mixes CO2, Air and N2 to the desired concentration ranging between 0-10% for both CO2 and O2, and at controlled pressure in the range of 0-2 barg (0-30 psig).

Delivery pressure is easily regulated by adjusting the knob of the embedded pressure gauge. The device is equipped with a mixing tank to ensure the highest composition stability even when the required output flow is variable.

The Tri-Gas Mixer is compatible with any mini-incubator available on the market.

Features

Output pressure in the range of 0-2 barg (0-30 psig)

CO2 and O2 accuracy: ±0.1%

Automatic switch to backup cylinder upon alarm

On board memory for data logging

Auto calibration with an external calibration gas

0-10 V or 0/4-20 mA analog output linear with the actual gas composition, for remote monitoring with an external data logger

Contact closure alarm

Auto diagnostic procedure

VOC-IN-BYPASS (optional) : VOC filter's holder with bypass panel to saturate newly installed filters with CO2 before using them with the trigas mixture

CO2-O2-MODULE

The Tri-Gas Mixer is equipped with a CO2-O2-MODULE, which contains the CO2 and O2 sensors.

The CO2-O2-MODULE measures with a high accuracy the CO2-O2 volume concentrations allowing automatic fine-tuning of the output gas. The CO2-O2-MODULE is factory calibrated using certified gas cylinders, and the factory calibration certificate is included in electronic format.

The CO2-O2-MODULE can be conveniently calibrated on-site with intuitive routines or can be easily extracted from the Tri-Gas Mixer, replaced with a spare CO2-O2-MODULE and sent out for calibration.

In both cases, there is no need to disconnect or turn off the Tri-gas Mixer to discontinue the gas supply to the incubators.

Self Calibration

The Tri-Gas Mixer features the self calibration procedure to periodically calibrate the CO2 and O2 sensors. It does this by using a connected calibration gas with a concentration close to what is used during the standard working condition.

The self calibration procedure is automatically and periodically repeated to maintain high accuracy for your operations. Moreover, the self calibration procedure can be manually started with an intuitive procedure.

The Tri-Gas Mixer always sends the proper gas to the connected incubators, even during the self calibration procedure.

Models

The Tri-Gas Mixer is compatible with any bench-top incubator available on the market.

Models are available with maximum output flow rate of 1.5 L/min and 15 L/min. The actual flow rate delivered automatically adjusts to match the requirements of the connected equipment.

TRI-GAS-MIXER-15L + AIR-COMPRESSOR-CP3-15L

Safety Features

The Tri-Gas Mixer features advanced safety routines to ensure that the incubators always receive the proper gas.

To enable the safety routines the Tri-Gas Mixer must also be connected to a premixed backup cylinder containing gas of the desired concentration.

The mixer will automatically switch to the premixed backup gas if any of the following conditions occurs:

• Pressure in the mixing tank becomes too low (for instance due to gas requirement exceeding maximum mixer capacity)

• Pressure of any of the input gasses becomes too low

• Target gas concentration cannot be achieved.
