ERBAY Air Cooled Water Chillers with integrated Free Cooling and Adiabatic
Cooling are designed to outdoor installation and 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/EEC
Electromagnetic Compatibility Directive (EMC) : 2004/108/EEC
Pressure Equipment Directive (PED) : 97/23/EC
The capacity of the Units varying between 124,1 kW and 962,0 kW and it’s
composed of the following parts;

Main Body: Chassis of the unit made from steel sheet iron and it’s designed
in special construction for able to carry weights on it. Frame and covers of
the unit made from galvanized steel sheet and it’s painted with electrostatic
powder paint.

Cooling Compressor: 1 or 2 pieces semi - hermetic compact screw
compressors, working with R407C refrigerant are used according to
customer request. Screw compressors as it’s characteristics can operate
without maintnance 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
V, 50 Hz.

Condenser: Air cooled condensers are manufactured by copper tubes
and aluminum fins. Current overload protected, high efficient direct drive
axial fans which have noiseless bearing are mounted on the Unit to provide
condensation of the refrigerant. Condensers can be manufactured with
epoxy coated fins on request.

Evaporator: Direct expansion evaporator is manufactured in Shell & Tube
form and special high eficient copper tubes are fixed to steel tubeheet
holes with tube expander method. Its’ 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 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 ones i 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 waterte mperatures,
entering water temperature of free cooling coil, ambient temperature,
refrigerant pressures on 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 digital screen and also capacity
control can be made easily. Microprocessor control system decides to
which modules (mechanical and/or free cooling) will be active depending
on ambient temperature and required water leaving temperature. Operating
times of each compressor is balanced so optimum eficiency is provided on
multi compressor units.

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