NRC
Non-Refrigerated Coolers

NRCW- WATER-COOLED NRC COOLERS
Use central chilled water, instead of refrigeration, to provide close temperature control of recirculating coolants or oils.

Any R-Closed-Loop or RO-Open-Loop cooler can be supplied with the NRCW option that replaces the standard refrigeration system with a water-to-coolant or water-to-oil heat exchanger. If chilled water is available at the installation, significant savings can be achieved in both initial and operating cost by using this chilled water to control the temperature of coolants being recirculated to your process.
 
Chilled water must be at least 10ºF (6ºC) colder than the lowest desired coolant temperature and have adequate flow and pressure for the application. Consult Turmoil for requirements.
 
A digital temperature controller operates an electronic mixing valve to control the flow of chilled water through the heat exchanger to provide close temperature control of recirculating fluids.
 
There are significantly fewer moving parts to maintain. Heat from the process is removed as warm water to a central location where it can be used or dissipated efficiently.

NRCA- AIR-COOLED NRC COOLERS
Use ambient air, instead of refrigeration, to provide close temp-erature control of recirculating coolants or oils.

Many R-Closed-Loop or RO-Open-Loop coolers can be supplied with the NRCA option that replaces the standard refrigeration system with an air-to-coolant or air-to-oil heat exchanger. Significant savings can be achieved in both initial and operating cost by using ambient air to control the temperature of coolants being recirculated to your process.
 
Ambient air must be at least 15ºF (9ºC) cooler than the lowest desired coolant temperature. Desired coolant temperatures must usually be above 110ºF (44ºC).
 
A digital temperature controller cycles a fan moving air across a fin coil heat exchanger to provide close temperature control of recirculating fluids.
 
All models are supplied with cleanable aluminum air intake filters.
