PolyScience? Recirculator; -10 to 70°C; 0.33 hp; centrifugal pump with heater; 120V

Handle process temperatures from -10 to 40°C—ideal for many routine process cooling needs

Temperature and pressure/flow readouts

Quiet operation, simple maintenance

High and low temperature alarms

Sealable reservoir

These affordable recirculators provide you with clean, cool or warm water without the scale buildup or the costly waste water disposal normally encountered with single-use tap water systems. A built-in filter cleans circulating fluid. To help optimize cooling efficiency for a particular application, they are available in a wide selection of cooling capacities, compressor sizes, and pump types. 

All feature convenient "one-touch" temperature control and bright extra-large LED readouts which can be read easily—even from across the room—and let you check temperature set point and fluid flow rate and pressure with just a quick touch. An easy-to-use calibration function allows you to adjust the unit’s temperature display to match a traceable temperature standard. Optional interfaces for various control functions, such as remote on/off and remote control, are available; call for details.

For added operational safety, audible and visual alarms that alert you instantly when operating parameters—such as fluid temperature or pressure, flow rate, or ambient temperature—exceed preset limits. User-adjustable high and low temperature limits prevent unauthorized set point changes, plus built-in safeties to alert you to low fluid levels and thermal runaway. The turbine pump models have an internal pressure relief valve that provides adjustable pumping pressure from 20 to 100 psi and a front-panel gauge let you monitor pressure.

The 1/2" NPT(F) inlet/outlet ports allow hookup to a variety of external equipment such as electron microscopes, diffusion pumps, AA furnaces, and mass spectroscopy systems.

Note: Do not use water in recirculator for low temperatures. Requires use of an antifreeze type liquid such as ethylene glycol or silicone. See bath fluids .
