The design working pressure of the coil is 650 PSIG (45 bar). 5 and 1.5 mm (40 mesh) is recommended upstream of the heat exchanger to prevent clogging.ĬOndEnSER Coils – Fin and tube condenser coils of seamless, inter- nally-enhanced, high-condensing-coefficient, corrosion resistant copper tubes are arranged in staggered rows, mechanically expanded into aluminum fins. Water inlet and outlet connections are grooved for compatibility with factory supplied victaulic connections.Ī strainer with a mesh size between. Installing contractor must include ac- commodations in the chilled water piping to allow proper drainage and venting of the heat exchanger.

TheĬooler is covered with 3/4” (19mm) flexible, closed-cell, foam insulation (K~0.25).īrazed plate heat exchangers shall be UL (Underwriters Laboratories) listed. The heater provides freeze protec- tion for the cooler down to -20☏ (-29☌) ambient. Compressor crankcase heaters are also included for extra protection against liquid migration.ĬOOLER The cooler is equipped with a heater controlled by a separate thermostat. A large internal volume and oil reservoir provides greater liquid tolerance. All rotating parts are statically and dynamically balanced. The YCAL compressors incorporate a compli- ant scroll design in both the axial and radial direction.

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 ac- cordance with ARI Standard 550/590-2003.ĬOMPRESSORS The chiller has suction-gas cooled, hermetic, scroll com- pressors. 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. This galvanized 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”. The unit structure is heavy-gauge, galvanized steel. After assembly, a complete operational test is performed with water flowing through the cooler to assure that the refrigeration circuit operates correctly. The unit is pressure-tested, evacuated, and fully charged with Refrigerant-410A and includes an initial oil charge. The 15 - 65 Ton (53 - 218 kW) YCAL models are shipped complete from the factory ready for installation and use. 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 pressed-steel base. They are completely self-contained and are designed for outdoor (roof or ground level) installation. YORK Air-Cooled Scroll Chillers provide chilled water for all air conditioning applications using cen- tral station air handling or terminal units.
