Technical Information ECC Series
ECC Series
The ECC series is similar to the EC series except it incorporates an
internal check valve, providing reverse flow of up to 2 tons for hot or
cool gas defrost applications. This eliminates the need for an exter-
nal check valve and related hot gas plumbing. A brass body, ODF
solder connections, and a removable inlet strainer make installa-
tions easier. New Rainbow Charges™ are indicated in the chart
below for medium temperature “W” charges, low temperature “Z”
charges or MOP “X” charge for those applications.
Specifications
Applications
• Heat Pump Units
• Air Conditioning Units
• Freezers
• Walk-in Boxes
• Refrigerated Cases
Notes:
1. Maximum operational pressure 500 psig (35 bars) high side and 275 psig (19 bars) low side.
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.
