Charge Type
"W” (all-purpose) liquid charge maintains nearly flat superheat control over a -40°F to +60°F (-40°C to +15°C) evaporator temperature range.
“Z” (low temperature) charge provides fast pulldown benefits like a gas charge with the non-migrating benefits of a liquid charge; usable over a -40°F to 0°F
(-40°C to -20°C) evaporator temperature range.
“X” (damped response) gas charge provides a pressure limiting (MOP) charge with anti-hunt characteristics over a -40°F to +60°F (-40°C to +15°C) evaporator
temperature range.
Notes: M.O.P. not available on “W” or “Z” charge.
*May not be used on systems in which bulb temperature will exceed 130°F (i.e. defrost). Contact Parker for pressure and temperature.
1. Maximum operational pressure 500 psig (35 bar).
2. Maximum storage temperature 130°F (55°C) .
3. Consult Parker for pressure and temperature exceptions.
4. Do not use “W” or “Z” liquid charges in applications where bulb temperatures can exceed 130°F (55°C).
For these applications use type “X” MOP gas charge only.
