This can be used for a single purpose such as heating or cooling, or their function can be alternatedbetween heating and cooling by changing the temperature of the water flowing through the coil.
Dependingon the application, it may be necessary to use a glycol mixture to prevent the liquid from freezing.water coils are engineered to operate at pressures up to 250 PSIG and temperatures up to300°F, but ancillaryequipment such as valves and pumps will often dictate lower operating temperatures. All water coils arepressure tested at the factory with Safety and quality assurance.
