Capacity Control - Capacity control is provided by solenoid-actuated, capacity control valves, which are controlled by the microprocessor centre. Lubrication - The lubrication is force-fed by a reversible oil pump to all crankshaft and bearing surfaces through a fine mesh stainless steel oil strainer. The connecting rods are aluminium alloy with integral bearing surfaces on both ends. The pistons are aluminium alloy with two piston rings. Cylinder Assemblies - Suction and discharge valves are high-quality, non-flexing, stainless steel. The main bearings are insert type, steel-backed babbitt. Crankshaft - The crankshaft is ductile (nodular) iron, drilled for positive oil distribution, with integral counterweights for balancing. Housing - The compressor housing is cast iron, and contains: removable cylinder heads with internal muffling, suction and discharge service valves, crankcase sight glass and heater, oil and suction strainers, and internal relief valves. Starting is by Part Winding or optional Star/ Delta. The terminal boxes are to IP55 weather protection. Motor - The compressor motors are refrigerant gas cooled, with integral temperature-sensing solid state overload protection in each phase. All rotating parts are statically and dynamically balanced. Compressors The chiller has accessible, semi-hermetic, reciprocating compressors. The unit base and frame is of heavy-gauge, galvanised steel, with baked-on powder paint (Desert Sand (RAL 1019)).

After assembly a full run test is performed, with water flowing through the cooler, to verify that each refrigeration circuit operates correctly. The unit is pressure-tested, evacuated and fully charged with refrigerant and includes an initial oil charge. YDAJ units are shipped in two sections and require the installation of a two wire communication link between control panels. SPECIFICATION General YCAJ and YDAJ models are completely assembled with all interconnecting refrigerant piping and internal wiring, ready for field installation.
