- Low cost cooling system - low power consumption.
- Energy saving - dissipated heat can be recovered for space heating.
- Closed loop system eliminates water consumption (of cooling tower system), reduces sewer charges - no loss of industrial fluids.
- Uses ambient air - can be installed to provide air make-up.
- Can be used with ethylene glycol for winter operation.
- Approach temperatures of 5°F and above.
|High Efficiency Coil
Corrosion Resistant Construction
- Smooth wall copper tubes are mechanically expanded into aluminum fins. All models are 10 fins per inch. High capacity (12 FPI) and wide line spacing (8 FPI) are available.
- Tube sheets are aluminum with collars, preventing tube wear due to thermal expansion.
- Coils are tested at 400 PSIG under water
- Vent (1/8 MPT) and drain (1/2 MPT) connections are standard.
- Steel (MPT) inlet and outlet connections are standard.
- Optional fin materials are vinyl coated aluminum or copper.
