MILLENNIUM CONTROL CENTER All controls are contained in a NEMA 3R/12 (and equivalent to IP55*) cabinet with hinged outer door and includes: Liquid Crystal Display with Light Emitting Diode backlighting for outdoor viewing: Two display lines Twenty characters per line Color coded 12-button non-tactile keypad with sections for: DISPLAY/PRINT of typical information: Chilled liquid temperatures Ambient temperature System pressures (each circuit) Operating hours and starts (each compressor) Print calls up to the liquid crystal display: Operating data for the systems History of fault shutdown data for up to the last six fault shutdown conditions An RS-232 port, in conjunction with this press-to-print button, is provided to permit the capability of hard copy print-outs via a separate printer (by others). The cooler is covered with 3/4' flexible, closed-cell, foam The heater provides freeze protection for the cooler down to -20oF (-29☌) ambient. The cooler is equipped with a heater controlled by a separate thermostat. They feature ball bearings that are double-sealed and permanently lubricated. Motors – The fan motors are Totally Enclosed Air-Over, squirrel-cage type, current protected. All blades are statically and dynamically balanced for vibration-free operation. The fan guards are constructed of heavy-gauge, rust-resistant, coated steel. They are directly driven by independent motors, and positioned for vertical air discharge.

The are designed for maximum efficiency and are statically and dynamically balanced for vibration free operation. Fans – The condenser fans are composed of corrosionresistant aluminum hub and glass-fiber-reinforced polypropylene composite blades molded into a low noise airfoil section. The design working pressure of the coil is 450 PSIG (31 bar).

CONDENSER Coils – Fin and tube condenser coils of seamless, internally-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 field supplied victaulic connections. Compressor crankcase heaters are also included for extra protection against liquid migration.

A large internal volume and oil reservoir provides greater liquid tolerance. All rotating parts are statically and dynamically balanced. The YCAL compressors incorporate a compliant scroll design in both the axial and radial direction. COMPRESSORS The chiller has suction-gas cooled, hermetic, scroll compressors.

Units are designed in accordance with NFPA 70 (National Electric Code), ASHRAE/ANSI 15 Safety code for mechanical refrigeration, ASME and rated in accordance with ARI Standard 550/590-98. This galvanized steel is coated with baked-on powder paint, which, when subjected to ASTM B117 500 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 either Refrigerant-22 (HCFC-22) or Chlorine-free Refrigerant-407C (HFC-407C) and includes an initial oil charge. The removable heads allow access to the internally enhanced, seamless, copper tubes. The water baffles are constructed of galvanized steel to resist corrosion. The 10 - 125 Ton (35 - 440 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, and a weather resistant microprocessor control center, all mounted on a formed steel base. They are completely self-contained and are designed for outdoor (roof or ground level) installation. YORK Millennium® Air-Cooled Scroll Chillers provide chilled water for all air conditioning applications using central station air handling or terminal units. 88 ISOLATOR SELECTIONS.90 ELECTRICAL DATA.
