![]() ![]() The heater provides freeze protection for the cooler down to -20 F (-29 C) ambient. ħ Water inlet and outlet connections are grooved for compatibility with factory supplied ANSI/AWWA C-606 cooler is equipped with a heater controlled by a separate thermostat. Installing con-tractor must include accommodations in the chilled water piping to allow proper drainage and venting of the heat exchanger. Compressor crankcase heaters are also included for extra protection against liquid plate heat exchangers are UL (Underwriters Laboratories) listed. A large internal volume and oil reservoir provides greater liquid tolerance. ![]() All rotating parts are statically and dynamically balanced. Units are designed in accordance with NFPA 70 (National Electric Code), ASHRAE/ANSI 15 Safety code for mechanical refrigeration, ASME, Listed and labeled with Intertek Testing Services (ETL) and rated in accordance with the latest version of ARI Standard 550 chiller has suction-gas cooled, hermetic, SCROLL compressors.Ħ The compressors incor-porate a SCROLL design that is compliant in both the axial and radial direction. Unit also includes service isolation valves as standard. Corrosion resistant wire mesh panels are added to protect the condenser coil from incidental damage and restrict unauthorized access to internal components. The steel is coated with baked-on powder paint, which, when subjected to ASTM B117 1000 hour, salt spray testing, yields a minimum ASTM 1654 rating of 6. After assembly, a complete operational test is performed with water flow-ing through the cooler to assure that the refrigeration circuit operates correctly.ĥ The unit structure is heavy-gauge, galvanized steel. They are completely self-contained and are designed for outdoor (roof or ground level) installation.Ĥ Each unit includes hermetic SCROLL compressors, a liquid cooler, air cooled condenser, a charge of refrigerant R-410A, and a weather resistant microprocessor control center, all mounted on a rugged, formed-steel 15 - 65 Ton (53 - 218 kW) YCAL models are shipped complete from the factory ready for installation and unit is pressure-tested, evacuated, and fully charged with R-410A and includes an initial oil charge. 97 Performance data provided in this document was created in accordance with Johnson Controls software: YORK works version and DXCHILL version CONTROLSFORM (915)4 THIS PAGE INTENTIONALLY LEFT (915)JOHNSON CONTROLS5 YORK AIR-COOLED SCROLL CHILLERS provide chilled water for all air conditioning applications using central station air handling or terminal units. 44 ISOLATOR DETAILS.ģ 80 ELECTRICAL DATA - 50 & 60HZ.
