345kW air cooled scroll chiller
Features
EKAC series air-cooled chiller (heat pump) units are highly
reliable, secure and flexible.
This series of units are elaborately designed to be delicate and
elegant. In addition, they can support fan coils and air handling
units of various specifications and models.
Units of this series are marked for their high efficiency, low
noise, user-friendliness, secure operation, easy installation and
maintenance etc, and are widely used in factories, stations,
hotels, villas, office buildings, top-grade residences etc.
Besides, they can also be used in industrial chilling.
EKAC1200 series units feature 3-grade modulation which can be
transformed to multi-grade modulations in modular combinations. For
example, 16 EKAC1200 units can realize 16 modulation grades with
effects very similar to that of stepless modulation. With operation
grades controlled electronically, the unit exerts less shock to the
power grid and saves more energy.
EKAC series units feature leading-edge technologies and name-brand
accessories which are strictly tested for compatibility. Fully
hermetic volute compressor and low-noise fans minimize the
operation noise. With efficient volute compressors and precise
throttling systems with electronic expansion valves, the units
feature high EER and COP, especially at partial workload.
Units can be controlled individually or together by an electronic
controller. The controller is strongly interference proof and can
exert control from as far as 1000 meters away. Failures are
indicated by error codes displayed on the controller to facilitate
troubleshooting.
The units are designed to best facilitate installation. The cooling
system is made hermetic in the factory. Customers do not need to
connect any copper pipe or refill refrigerant. The water system has
an inlet connector which is to be connected to the terminal
equipment. Having installed the unit as instructed, customers just
need to check that water and pump pipes are clean before pumping
water and powering on the unit.
The controller defrosts the unit automatically according to the
operation time of the unit and the temperature of the heat
exchanger.
The cooling system is protected against extreme pressures:
discharge pressure will not be too high, nor will inhaling pressure
be too low; against extreme discharge temperature: discharge
temperature will not be too high; against freezing during cooling
operation: when the water temperature is too low, the plate heat
exchanger will not freeze up or burst internally; and against low
temperature: during cold winter time, the water pipe and plate heat
exchanger will not freeze up or burst internally (This feature
works only when the system is working in the heating mode with the
main power supply turned on).
The unit shell is made of galvanized, phosphorized steel plate with
pure polyester plating to withstand weathering. The unit is
reasonably designed to save space. It can be mounted on walls,
balconies or the roof, thus eliminating the need for a dedicated
equipment room.
The unit is highly adaptive and can operate smoothly in hostile
conditions such as extremely high or low temperatures.
To access and service any part of the unit, you just need to
dismantle the side panel or the front panel. When the unit stops
working abnormally, the controller prompts the reason to facilitate
troubleshooting.
