Tube Heat ExchangerCommonly used in water chillers, these commercial-size heat exchangers are also widely used in water-to-water heat exchange where a facility-chilled water loop is available. The horsepower ratings shown are nominal and based on refrigerant to water applications. Water flow travels in and out through the top, allowing air to purge from the exchanger. The internal helical coil is made with titanium tubing and enclosed in 8" PVC pipe with 1 1/2" Armorflex insulation (ends are not insulated). One end is flanged for cleaning and inspection. Refrigerant connections are 3/4" SAE flare, water inlet/outlet connections are 2" unions. Digital temperature controllers can be used in conjunction with water solenoid valve on the heat exchanger in water-to-water applications. In water-to-water heating applications where process water in the titanium coil exceeds 130°F, CPVC shell and fittings are required (please inquire for pricing). Pressure loss 2–3 psi. Two-year warranty. Made in USA.
