1. General Description
Please read through this operation manual before using and installation to
avoid damage of the machine and personal injuries.
SIC-A series air-cooled chiller adopts single-stage vapour compressed circuit, with
compressor overload protection, pump overload protection, phase reverse alarm,
anti-freezing protection, high & low pressure protector, which features stable
performance and long service life. It can quickly cool down, and maintain stable
temperature to meet the requirements of customers. This series of products work
following the heating and cooling exchange principle, which is an indispensable
device for cooling applications in modern industry.
Model: SIC-7.5A

1.1 Coding Principle
1.2 Features
Standard configuration
Cooling range 7~25℃.
Stainless steel insulated water tank and evaporator
Anti-freezing protector
Adopt R22 refrigerant, and cooling effect
The refrigeration system adopts high and lower pressure controller for
protection
Low pressure pumps are standard configurations.
Compressor and pump overload relays.
Adopt Italian temperature controller that can maintain the accuracy of
0.1℃.
All adopt branded compressors with low noise, high efficiency and long
service life.
SIC-A adopts fin style condenser design without any need of cooling water
for excellent heat transfer and rapid cooling.
Accessory option

We reserve the right to change
specifications without prior noice.
Note:
1) Refrigeration capacity is measured based on the flow 0.172 m3/ (h.kW) and the outlet temperature (7℃) of
chilled water under the environment temperature of 35℃.
2) Low pressure pump is for domestic and Southeast Asia export, customers can change for medium
pressure pumps (use P for short; e.g.: SIC-5A-P) or high pressure pumps (use HP for short; e.g.:
SIC-5A-HP), specific parameters in turn as shown above.
3) Pump power is included in total power.
4) Special orders of machine voltage can be acceptable according to customers’requests.
