High efficiency system
The new series adopt more high efficient parts and unique design ensure the chiller high efficiency EER up to
3.4.COP above 3.4 (R410A Series).
EEV control, the 1400
steps high-performance
electronic expansion valve
High efficiency heat exchanger, Condenser adopts the Copper tube &
hydrophilic aluminum fin coil type structure, increase the heat exchange
efficiency 20%.
High Reliability
Backup operation function
The system has three modules, the actual operation of just two module, if one module malfunction another module
will start automatically according to the water temperature.
Operation
Three phase fan motor
Three phase fan motor,compared
with one phase fan motor low starting
current,
high speed and more stable.
Shell & Tube heat exchanger
The new modular chiller adopt
Shell&Tube heat exchanger avoid
dirty plugging,
higher efficiency and reliability.
Safety and protection
Phase reverse protection, high and
low pressure protection, freeze
protection, overheat protection,
overload protection, etc.
Stop Operation
High efficiency
compressor, adopts the
famous brand, low noise
level, high EER
Malfunction Stop
Filter drier
Filter drier,absorb moisture in the
system, avoid the emergence of
the "ice block"
Pressure sensor control
Through the pressure sensor
real-time monitoring, realize the
system quickly,
accurately control, ensure the unit
efficient and stable operation.
