  • 1.5 cubic feet per hour of CO2 output.
  • Anti-tip sensor.

Attaching Water Lines:

The MiniGEN heat exchanger has hose barb inlet and outlets designed for 1/2" inside diameter tubing.

We recommend a pump with a flow rate of at least 500 GPH if you choose to water cool the MiniGEN.

You can use a small (5 gallon) reservoir with a small chiller or, if you'd prefer not to use a chiller, a larger reservoir alone (minimum 25 gallons; depending on your application, a larger reservoir might be required).
