PolyScience 58809TD9A25R1 High-Capacity Recirculating Chiller

The PolyScience 58809TD9A25R1 is a 1.5 HP high-capacity recirculating chiller designed to provide continuous heat removal and temperature-controlled fluid circulation for demanding laboratory, analytical, and industrial equipment. With a 5°C to 35°C operating range and a high-flow turbine pump capable of circulating up to 11 GPM (41.6 L/min), this chiller is well suited for applications requiring substantial coolant flow and reliable continuous cooling.

Available used and refurbished from American Instrument Exchange, the PolyScience 58809TD9A25R1 combines refrigeration, a 13.25 L reservoir, digital monitoring, and high-volume fluid circulation in a self-contained system. It is particularly useful for cooling lasers, electron microscopes, analytical instruments, and other heat-generating equipment where a dedicated recirculating cooling system is preferable to facility water. A 90-day warranty is included.

Overview

The PolyScience 58809TD9A25R1 is a refrigerated recirculating chiller designed to continuously remove heat from externally connected laboratory and process equipment. Rather than sending facility water through an instrument and then to drain, the chiller cools and recirculates a controlled volume of fluid through a closed cooling loop.

This particular model is configured for relatively high coolant flow. Its turbine pump can circulate up to 11 GPM, making the 58809TD9A25R1 particularly useful for applications with substantial coolant-volume requirements.

The integrated control system provides separate displays for temperature and pressure or flow information, allowing operators to monitor important cooling-system conditions during operation. User-adjustable alarms provide additional protection by alerting operators when operating conditions move outside selected parameters.

With its combination of substantial circulation capacity and a relatively compact footprint, the 58809TD9A25R1 can provide a dedicated cooling solution without requiring an unusually large amount of laboratory floor space.

Common Applications

The PolyScience 58809TD9A25R1 is suitable for laboratory and process equipment that generates substantial heat and requires a continuous supply of circulating coolant. Applications can include lasers, electron microscopes, analytical instrumentation, process equipment, condensers, vacuum systems, and other temperature-sensitive equipment.

Its high-flow turbine pump makes this model particularly appropriate for applications where moving a relatively large volume of coolant is more important than generating very high circulation pressure.

A recirculating chiller can also provide an alternative to once-through facility-water cooling in compatible applications. By continuously cooling and reusing the same heat-transfer fluid, laboratories can reduce water consumption while maintaining more consistent coolant conditions.

Ideal Laboratory Types

The PolyScience 58809TD9A25R1 is well suited for analytical laboratories, materials-science facilities, physics and optics laboratories, industrial research environments, pharmaceutical facilities, electronics research groups, quality-control laboratories, academic research facilities, and other laboratories operating heat-generating instrumentation.

The combination of a high circulation rate and dedicated refrigeration makes this model particularly attractive for laboratories running equipment continuously or managing larger thermal loads.

Temperature Control & Stability

The PolyScience 58809TD9A25R1 provides an operating temperature range from 5°C to 35°C with specified temperature stability of approximately ±0.5°C.

Unlike refrigerated circulators designed to reach very low subzero temperatures, this model is optimized for equipment and process cooling within a narrower range around typical laboratory temperatures. For many instrument-cooling applications, the objective is not to achieve extremely low temperatures but to continuously remove heat while maintaining a consistent coolant supply temperature.

Actual performance will depend on the thermal load generated by the connected equipment, ambient conditions, coolant selection, circulation rate, and installation. Buyers should compare the heat generated by their equipment with the chiller's available cooling performance at their intended operating temperature.

Circulation & Pump Performance

The turbine pump is one of the most important features of the PolyScience 58809TD9A25R1. It provides a maximum circulation flow rate of approximately 11 GPM, equivalent to 41.6 L/min.

This relatively high flow rate makes the chiller useful for equipment requiring substantial coolant movement through a comparatively unrestricted circulation loop. It also distinguishes the unit from positive-displacement chillers, which generally emphasize higher pressure at lower maximum flow rates.

Actual flow through connected equipment will depend on tubing diameter and length, fittings, coolant viscosity, elevation changes, operating temperature, and hydraulic restrictions within the external system.

When selecting a chiller, buyers should therefore consider both flow and pressure requirements rather than assuming that maximum flow alone determines compatibility.

Refurbishment & Testing

This used PolyScience 58809TD9A25R1 Recirculating Chiller is refurbished and tested by American Instrument Exchange before shipment. Our technicians inspect the refrigeration system, circulation pump, reservoir, temperature controller, displays, alarms, electrical components, and fluid connections and operate the system to confirm proper functionality.

Temperature-controlled equipment is tested using NIST-traceable probes and data loggers. Pump operation and fluid circulation are evaluated, while the refrigeration system is operated to verify appropriate cooling and temperature control. The reservoir and fluid-contact areas are also cleaned and inspected prior to shipment.

If your application requires operation at a particular coolant temperature or has specific testing requirements, contact American Instrument Exchange before shipment. When practical, our technicians can incorporate customer-requested conditions into final testing.

A 90-day warranty is included with this refurbished PolyScience recirculating chiller.

Choosing the Right Recirculating Chiller

Selecting the correct recirculating chiller requires matching the system to both the thermal and hydraulic requirements of the equipment being cooled. Important factors include required coolant temperature, cooling capacity, flow rate, pump pressure, reservoir volume, electrical service, and the resistance of the external circulation loop.

The PolyScience 58809TD9A25R1 is particularly well suited for applications requiring high coolant flow within a 5°C to 35°C operating range. Its 11 GPM turbine pump provides considerably more circulation volume than many smaller laboratory chillers.

Electrical requirements are especially important with this unit. The 58809TD9A25R1 requires 430 V, 60 Hz, 17.7 A, three-phase electrical service, so laboratories should verify that appropriate power is available before purchasing or installing the chiller.

Applications requiring substantially lower temperatures, very tight temperature stability, or high-pressure circulation through highly restrictive equipment may be better served by a different circulator configuration.

American Instrument Exchange can help compare available used and refurbished recirculating chillers based on your equipment's target temperature, thermal load, circulation requirements, and available electrical service.
