S&A CWFL-2000 dual temperature water chiller machines with 6500W cooling
capacity,±0.5℃ precise temperature control and multiple alarm functions are specially
designed for cooling 2000W fiber lasers.
The CWFL series water chillers are so multi-functional that the laser device and the QBH
connector/optics can be cooled by the low temperature control system and the high temperature
control system respectively at the same time, which can greatly reduce the generation of the
condensed water and save cost & space.
Laser water chiller machines features
1. 6500W cooling capacity; optional environmental refrigerant;
2. ±0.5℃ precise temperature control;
3. The intelligent temperature controller has 2 control modes, applicable to different applied occasions; with
various setting and display functions;
4. Dual temperature to satisfy different needs of fiber laser device and the optics;
5. With Ion adsorption filtrating and test functions conform to fiber laser device operating requirements;
6. Multiple alarm functions: compressor time-delay protection, compressor overcurrent protection, water flow
alarm and over high / low temperature alarm;
7. Multiple power specifications; CE approval; RoHS approval; REACH approval;
8. Optional heater and water filter.

TEMPERATURE CONTROLLER PANEL DESCRIPTION
S&A industrial water chillers are popular for its 2 temperature control modes as constant
temperature and intelligent temperature control.Generally speaking, the defaulted setting for the
temperature controller is intelligent temperature control mode. Under intelligent temperature control
mode, the water temperature will adjust itself according to the ambient temperature. However,
under constant temperature control mode, users can adjust the water temperature manually.
Suggestion:
Intelligent temperature control mode for QBH connector/optics
Constant temperature control mode for laser device

Alarm function
(1) Alarm Display:
When alarm occurs, the error code and the temperature will be alternately displayed.
(2) To suspend the alarm:
In alarming state, the alarm sound could be suspended by pressing any button, but the alarm display remains until
the alarm condition is eliminated.
ALARM AND OUTPUT PORTS
In order to guarantee the equipment will not be effected while abnormal situation happens on the chiller,
CWFL-2000 series chillers possess alarm protection function.
1. Alarm output terminals and wiring diagram.
2. Alarm causes and working status table.

Note: The flow alarm is connected to the normally open relay and normally closed relay contacts,
requiring operating current less than 5A, working voltage less than 300V.
CHILLER APPLICATION

10. www.teyuchiller.com
WAREHOUSE
18,000 square meters brand new industrial refrigeration system research center and production base. Strictly
execute ISO production management system, using mass modularized standard produces, and standard parts rate
up to 80% which are the source of quality stability.
Annual production capacity of 60,000 units, focus on large, medium and small power chiller
production and manufacture.
TEST SYSTEM
With excellent laboratory testing system, simulates actual working environment for chiller. Overall performance
testing before delivery: aging test and complete performance test must be ex ecuted on each finished chiller.
