1.1.3 Product features
The all-inverter modular air-cooled chillers work outstandingly by virtue of their major features stated
below.
(1) Excellent compatibility
The modular air-cooled chillers can be constructed of multiple single units with the same or different
structure or capability (35kW, 60kW, 65kW, 130kW). For the 35kW unit, it has only one cooling system; for
the 60kW, 65kW units, they are of two independent systems; for the 130 kW unit, there are four uniform
independent systems. Up to 16 single units can be modularized, with cooling capacity ranging from 35kW
to 1040kW.
(2) Comfort and energy saving
The inverter can quickly respond to load change and lead to decreased water temperature fluctuation
and better comfort.
(3) Ultra quiet operation
The high-efficiency and low-noise fan blades and motor as well as the optimized air passage can
greatly lower operation noise of the unit. Besides, the quite mode can provide the user a ultra-quiet
environment.
(4) Powerful self-protection
It is equipped with the top-end microcomputer control system which is capable of providing well-
rounded protection and self-diagnosis.
(5) High reliability
It is constructed of well-designed refrigeration parts and well-designed system, structure and electric
control, adequately guaranteeing reliable operation.
(6) Remote ON/OFF
The unit can be started or stopped by the ON/OFF key operation.
(7) Equilibrium running
It indicates each compressor will run alternately so as to extend their service life.
(8) Shiftwork of water pumps
Two water pumps can work alternately with equilibrium runtime so as to extend their service life and
lower the maintenance difficulty.
