Various Purpose

Capacity Range

111,8 kW , 2435 kW

ERBAY Water Chillers are designed to provide chilled water
leaving temperatures which are given on capacity tables
in our factory carrying out EN 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 111,8 kW and
2.435 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 3
ph, 400 Volt, 50 Hz.

Condenser: Manufactured in Shell & Tube form and special
high efficient copper tubes are fixed to grooved steel tubesheet
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.

Electrical Control Panel: The panel is designed to IP54.
To operate the Unit automatically and securely, the panel is
composed of two different section. The first section is power
section and the other one is control section.The panel is equipped
with enough number of contactors, thermics,fuses and on-off
switchs. The panel and wiring are in conformity with EN 60204-
1 standart. Required power supply is 3 ph, 400 Volt, 50 Hz.

Microprocessor Control System: 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, occured superheat temperature, operating
times of compressors, all faults occured on the system and
all alarm history can be seen on the digital screen and also
capacity control can be made easily. Besides the operating
times of each compressor is balanced automatically and
optimum efficient operation of the Unit is provided.

Components of the Cooling Circuit: To operate the
Unit automatically and securely; electronic expansion valve,
drier-filter, sight glass, relief valve, flow-switch, high and low
pressure switches and shut-off valves are included.
