ERBAY Water Chillers are designed for outdoor installation and provide chilled water leaving temperatures which are given on capacity tables in our factory carrying out EN ISO 9001:2015 Quality Management System. The Units are supplied to be ready for installation. All connections, oil and refrigerant charges, and required tests are made in our factory. Our units are in conformity with the health and safety requirements of European Union directives and relevant harmonized standards. Also adiabatic - free cooling integration is available for each model. ERBAY provides 4 different air-cooled water chillers models according to demand: *Semi-hermetic Compact Screw (EBHV) *Hermetic Scroll ( EBHS) *Semi-hermetic Reciprocate (EBHP) *Packaged Type Water Chillers (PAKCOLD) Semi-hermetic Compact Screw (EBHV): 1 or 2 pieces of semi-hermetic compact screw compressors are used according to customer request. Screw compressors as their characteristics can operate without maintenance needs for a long time. Maintenance screw compressors are quite simple because of the less amount of moving parts in them. Screw compressors are equipped with discharge shut-off valves, a check -valve that prevents to return back of the refrigerant from the discharge line, an oil level switch, an oil sight glass, an oil separator, an oil filter, a crankcase heater, a capacity control solenoids, vibration dampers, motor protection device and temperature sensors (PTC). Hermetic Scroll (EBHS): According to capacity hermetic scroll compressors are used between 1 and 6 pieces and compressors are used as single, tandem, or trio on each independent refrigerant circuit. Tandem and trio compressors are mounted on solid frame rails so vibration effect is prevented. Equal oil distribution is provided on compressors by using an oil equalizing system. Semi-hermetic Reciprocating Compressor (EBHP): 1 or 2 pieces of semi-hermetic reciprocating compressors that are produced especially for marine applications are used according to capacity. The ability to reach and apply maintenance to each part of the compressor is provided. Standard power supply is 3ph - 400 Volt - 50 Hz Packaged Type Water Chillers (PAKCOLD): Enamouous product design which can include a domestic water tank, pump, and all necessary components. Plug-and-play installation and user-friendly control provide the best solution. Condenser: Air-cooled condensers are manufactured by collating special profile aluminum fins on copper tubes. Copper tubes are expanded special process in order to increase thermic conductivity between copper tubes and aluminum fins. This means heat transfer reaches to maximum level. Fan: The highly efficient axial fan which is directly coupled with the motor, noiseless bearing, balanced statically and dynamically is mounted on the device to provide the condensation of the refrigerant in the condenser. Evaporator: Direct expansion evaporator is manufactured in Shell & Tube form and special highly efficient copper tubes are fixed to steel tube sheet holes with the tube expander method. It's allowed to maintain and clean up because of the removable tube bundle. Evaporators are in conformity with EN 14276-1 and EN 13445 standards and are designed for chilling water and glycol brines. The external surface of evaporators and compressor suction lines are insulated with insulation material with suitable thickness. Electrical Control Panel: The panel is designed for IP54. To operate the Unit automatically and securely, the panel is composed of two different sections. The first section is the power section and the other one is the control section. The panel is equipped with enough contractors, thermic, fuses, and an on-off switch. The panel and wiring are in conformity with EN 60204-1 standard. Microprocessor Control System: A microprocessor control system is used on the Unit. By means of this; entering and leaving water temperatures, refrigerant pressures on the suction and discharge lines, occurred superheat temperature of the evaporator, operating times of compressors, all faults that occurred on the system and all alarm history can be seen on the digital screen, and also capacity control can be made easily. Besides condenser fans are controlled automatically depending on the ambient temperature and the operating times of each compressor are balanced so that optimum efficient operation of the Unit is provided. Components of the Cooling Circuit: To operate the Unit automatically and securely; an electronic expansion valve drier-filter, sight glass, relief valve, flow-switch, high-low pressure switch, and shut-off valves are included.
