  If the propane cylinder of your Onyx Scrubber forms condensation or ice, it could be due to: * Propane fuel leaking. Close the propane main fuel service valve and check the fuel lines, REGO fitting, and regulator for any leaks. * It is normal for a propane cylinder to operate at a colder temperature than ambient, which may cause condensation or ice formation depending on ambient temperature and humidity levels.

  If the propane regulator on your Onyx Scrubber freezes and prevents the flow of propane, it could be due to: * Liquid propane entering the regulator. Ensure the cylinder is designed for VAPOR withdrawal, is designed for the correct orientation (horizontal or vertical), and is installed in the correct orientation. Make sure the locator pin is inserted into the positioning slot on the cylinder collar, and follow orientation arrow indications/labels on the cylinder. Also, ensure the propane cylinder is not overfilled and that the application doesn't allow operating angles to exceed equipment OEM instructions. * Low ambient temperature. It is normal for a propane regulator to operate at a colder temperature than the ambient temperature, which may cause condensation or frost formation depe...
