Energy Saver
Technical Systems (TSI) Series 42 Air cooled chiller with waterside economizer units have been specifically designed for applications requiring year-round operation to provide energy saving by reducing run time of compressorized equipment and taking advantage of the cool ambient temperature. Series 42 chillers are completely factory assembled including, air cooled fluid cooler, pump system, controller and all interconnecting wiring piping. We offer factory run (functional) test for all chillers prior to shipment as a standard option every day.
Whether you need great payback for the unit, green refrigerant unit or great lead time, our combined capability of specific application engineering and expertise in manufacturing custom equipment will provide limitless solutions for your needs.
