    Blast Chiller, is it considered a low pressure (EPA Type III)?

    Hey Guys,

    Just wondering about this, is a blast chiller considered a low pressure unit or a high pressure unit?

    I have one that seems to run at about 4 PSI suction and 200 something on the liquid side, would that be considered low pressure then? Per EPA? I guess I could look up the refrigerant and check the pressures but not totally confident in that.

    It's definitely not a low pressure Type III appliance:

    Low-Pressure Appliance - (definition unchanged by the EPA's March 12, 2004 rule change) An appliance that uses a refrigerant with a liquid phase saturation pressure below 45 psia at 104F. Evacuation requirements for the low-pressure category apply to these appliances. This definition includes but is not limited to appliances using R-11, R-113, and R-123.

    Okay cool, just wanted to check.

    Its more for myself personally, I don't think we've ever had EPA or an inspector come through here.
