ERBAY Water Chillers are designed to provide chilled water leaving temperatures which are given on capacity tables in our factory carrying out ISO 9001:2008 Quality Management System. The Units are supplied to ready for installation. All connections, oil and refrigerant charge and required tests are made in our factory. Our units are in conformity with health and safety requirements of following European Union directives and relevant hormonized standarts.
Machinery Directive (MD) : 2006/42/EC
Low Voltage Directive (LVD) : 2006/95/EC
Electromagnetic Compatibility Directive (EMC) :2004/108/EC
Pressure Equipment Directive (PED) : 97/23/EC
The capacity of the Units are varying between 111,2 kW and 1987,2 kW and it’s composed of the following parts;
Cooling Compressor: 1 or 2 pieces semi-hermetic compact screw compressors are used according to capacity. Screw compressors as it’s characteristics can operate without maintenance need for a long time. Maintenance of the screw compressors are quite simple because of the less amount of the moving parts in it. Screw compressors are equipped with discharge shut-off valve, check-valve that prevents to return back of the refrigerant from the discharge line, oil level switch, oil sight glass, oil separator, oil filter, crankcase heater, capacity control solenoids, vibration dampers, motor protection device and temperature sensors (PTC). Required power supply is 3ph, 400 Volt, 50 Hz.
Condenser: Manufactured in Shell & Tube form and special high efficient copper tubes are fixed to grooved steel tube sheet holes with tube expander method. Condensers are in conformity with EN 14276-1 and EN 13445 standarts.
Evaporator: Direct expansion evaporator is manufactured in Shell & Tube form and special high efficient copper tubes are fixed to grooved steel tubesheet holes with tube expander method. It’s allowed to maintenance and clean up because of the removable tube bundle. Evaporators are in conformity with EN 14276-1 and EN 13445 standarts and designed for chilling water and glycol brines. External surface of evaporators and suction lines are insulated with insulation material with suitable thickness.
