1.2 System Introduction
The recirculating cooler, also called as chiller, draws heat from bath liquid via the
cooling system for instrument or equipment that need to be cooled (Water is a
common bath liquid, other liquid, such as glycol is used for lower temperature) to
ensure instrument or equipment to work properly under the normal temperature.

Circulation is looped between the chiller and the instrument depending on the
pump’s pressure inside the chiller, and the temperature sensor detects the
medium temperature to realize the control of the cooler.
The recirculating cooler is applied vastly on laboratory test equipment such as
rotary evaporators, X-ray diffractometer, ICP emission spectrometer, ICP-MS,
graphite furnace AAS, ED-XRF, electron microscope, medical CT, medical
physiotherapy chiller, production test chiller, precision grinder, computer
numerical control machine, machining center, laser equipment etc.
This chiller is an integral product with parts such as condenser, compressor,
evaporator and pump inside the same case.

Location Principle
1
Firm ground or experiment table in a dust-free and cool environment with
good ventilation
2
Far from droplets or steam
3
Far from the location that influx, viscous flow, leak of fuel gas may happen
4
Far from high frequency devices such as high frequency welding machine
5
Far from the location where acidic solutions used frequently
6
Far from the location where special sprayer (sulfide contained) used
frequently
7
Ambient temperature 5 ° to 30 ° C, relative humidity less than 80%
(non-condensing)
As for convenience and safety of maintenance and installation, keep certain
distance between the indoor unit and obstacles.
Ensure the measurements during indoor installation:
1）The distance between the bath top and obstacles shall be at least 300mm;
2）The distance between two bath sides and obstacles shall be at least 500mm;
3）The distance between bath back and obstacles shall be at least 500mm;
4）The distance between bath front and obstacles shall be at least 1000mm;
Such as following picture:(unit: mm)

1-2 times enlarge the distance if large size unit installed.
Unit installation:
Unpack the unit and check the packing list, if there is a shortage contact your
local distributor for solutions .
Move the unit from the packing base to spacious position and check for damages
incurred during transit. Install the unit in the proper position and ensure it is stable
and safe, then install the external circulating loop pipelines.
Please ensure correct collection of the external circulating water loop (That is,
the water outlet of the chiller should be connected to the water inlet pipe of the
instrument needs to be cooled; the return pipe of the instrument should be
connected to the water inlet ).
Please pay attention to joint leakage after injection of the bath liquid. If
