Polystat 2-1
Cole Parmer
Cooling capacity based on
•
PD 1pump with no backpressure. Heat input from the pump will
result in a reduction in cooling capacity. The cooling capacity reduction will vary based on the
pump chosen as well as pump backpressure and flow. 60 Hz chillers.
Specifications obtained at sea level using water as the recirculating fluid, at a 20°C process
•
setpoint, 20°C ambient condition, at nominal operating voltage. Other fluids, fluid temperatures,
ambient temperatures, altitude or operating voltages will affect performance. See Section 3.
Keep the reservoir full at all times. Low fluid levels will result in loss of cooling capacity if the
•
fluid level is allowed to drop below the cooling coils.
Cole Parmer reserves the right to change specifications without notice.

General Information
The Cole Parmer Polystat recirculating chiller is designed to provide
a continuous supply of fluid at a constant temperature and flow rate.
The chiller consists of an air-cooled refrigeration system, reservoir
tank evaporator coil, recirculating pump, polyethylene reservoir, and a
microprocessor controller.
It is designed for continuous operation and for indoor use in accordance with
all the procedures and requirements stated in this manual.
Specifications
* 60 Hz units. The MD pump is only available in 12911-12, 14. Pumping capacity pressure values
are differential pressures between the inlet and the outlet of the unit.
