S&A CW-6000DN Industrial Water Chiller for 100W Solid-state Laser, 22KW CNC Spindle, 30W-300W Fiber Laser Cooling, 1.52HP, AC 1P 110V, 60Hz

Description

S&A CW-6000 series is high-precision compression refrigeration Water Chiller, with intelligent temperature control,completed configuration,perfect protection and alarm system.
S&A industrial water chillers are popular for its 2 temperature control modes as constant temperature and intelligent temperature control. Under intelligent mode, the water temperature is adjusted according to ambient temperature to avoid producing condensate water and protect the laser tube.You can adjust the water temperature under constant temperature.

Suggestion:
Intelligent temperature control mode for summer
Constant temperature control mode for winter
Note: Cooling water additive is forbidden by express company, so we could not put it into the package. You can buy it from local.

Features：

• 3000W cooling capacity; optional environmental refrigerant;
• ±0.5°C precisely temperature control; 
• The intelligent temperature controller has 2 control modes, applicable to different applied occasions; with various setting and display functions;
• Multiple alarm functions: compressor time-delay protection, compressor overcurrent protection, water flow alarm and over high / low temperature alarm;
• Multiple power specifications; CE ,RoHS and REACH approval;
• Long working life and simple operation;
• Optional heater and water filter.

Temperature controller panel description：

The intelligent temperature controller does not need to adjust the controlling parameters under normal circumstance. It will self-adjust controlling parameters according to room temperature for meeting equipment cooling requirements.  
User also can adjust the water temperature as needed.

Temperature controller panel description：

• Indicators of temperature controller working status: 
  COMP         ON, compressor working
  SV               ON, solenoid valve working
  Heating      ON, heating rod working
  INT    Ctrl   ON, controller working in intelligent control mode
  CT     Ctrl    ON, controller working in constant temperature control mode
  PARAM Set ON, controller working in parameters setting mode
  ALM   OUT  ON, alarm output status
  Room Temp ON, displaying room temperature
  ST     DLA     ON, starting up delay status
• Press ▼ button to show the room temperature, 6 seconds later default display restored.
  (Meanwhile, Room Temp light is on, displaying room temperature.)
• ▲▼ buttons are for modifying parameters values andbuttons are for switching parameter items.
• RST button: confirm.
• SET button: setting function.

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 damaged while cooling water circulation is out of control, CW-6000series chillers possesses an unique low flow alarm protection.

(1) Flow alarm output ports and the wiring diagram

(2) Flow alarm causes of circulating cooling water and working state

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.
