Unit construction
Compact, modular and weatherproof design air-cooled chiller for outdoor installation – manufactured according to the ISO 9001 quality standard.
The ready-to-connect range has been designed for both air conditioning and process cooling applications and meets PED conformity. The use of state-of-
the-art technologies and high quality materials ensures efficiency, reliability and an extended service life.
Each chiller is subjected to a function test and test run in the factory allowing for standard requirements.
Casing / Colour
Painted, galvanised steel plate. Fully factory assembled on a base frame. Colour white / RAL 9002.
Number of refrigerant circuits
Size 030-049 single circuit, 050-095 double circuit.
Each refrigerant circuit has its own fully independent design thereby guaranteeing a high level of system reliability.
Compressor
Hermetically sealed scroll type compressor with generator gas-cooled motor for a nominal rpm of 2900 revs/min, electronically protected against excess
temperature and excess current. Completely impervious to water ingress thanks to patented chamber seals and articulated coupling. Lubrication system
with dynamic oil pump and inspection glass. Construction-specific, extremely low level of vibration.
Condenser
Condensation register with continuous running and surface-corrugated aluminium flaps. The seamless copper pipes are permanently connected with the
flaps by means of mechanical flaring. The refrigerant subcooler to improve performance is an integral part of each refrigerant circuit with a liquid stopper
between the condenser and subcooler circuit. An epoxy resin coating permanently protects the flaps from corrosion thereby extending the field of
application of this device.
Fans
Low-noise aluminium axial fans with low rotary speeds complete with outlet protective grating, directly driven, statically and dynamically balanced,
weatherproof drive motors for outdoor operation and maintenance-free bearings. Motor safety class IP 55, group F. Winter starting device for operating
the machine down to minimum exterior temperatures of -10 °C as standard.
Evaporator
R-407C optimised DX counter flow plate heat exchanger made of stainless steel, plates brazed gastight with copper, for water and glycol mixtures. As from
module size 050 twin circuit design (two refrigerant circuits / one water circuit). A special refrigerant distribution system has been incorporated into the
plate duct for optimal capacity of the complete heat transmission surface. As well as an additional increase in efficiency, this is also responsible for stable
control behaviour in the heat exchanger. The plate heat exchanger is heat-insulated to ensure it is diffusion-proof to prevent any heat loss.
Piping
Refrigerant connecting conduits made of Cu pipe with the required cooling fixtures such as shut-off and filler valves, filter-driers, solenoid valve and
expansion valve. Suction line including insulation. refrigerant circuit is subjected to a pressure and leak test in the factory, is dried, evacuated and supplied
with refrigerant and filled with oil ready for operation. The plate heat exchanger is cased with galvanised steel and is fitted with a catch pan and an electronic
contactor.
Hydraulic module
To be able to cover a larger range of applications, the EUWY*030-095BZ6Y range can be supplied with or without integrated hydraulic components. Within
the standard scope of supply for EUWYN devices (basic unit), the mandatory contactor and a water filter are already included. The scope of supply of the
EUWYP devices also includes all components needed for operation as well as a circulation pump, expansion vessel, manometer, shut-off valves, safety valve,
purge, filling and drainage valve, maintenance connections and compensation valve. With the EUWYB variants, the scope of supply set out above is further
expanded with a buffer tank arranged under the unit.
Switching and control device
Weatherproof design factory-wired control cabinet, safety class IP54, assembled externally on the machine chassis, with all the components required for
automatic operation consisting specifically of the following:
