SPECIFICATION

CONTOUR AND PARTS INTRODUCTION

Connection diagram between water chiller and laser machine

Water outlet of the water tank connects to water inlet of the laser machine while water inlet of the water tank connects to water outlet of the laser machine. Aviation connector of the water tank connects to the aviation connector of the laser machine.

FLOW ALARM AND OUTPUT PORTS

In order to guarantee the equipment will not be damaged while cooling water circulation is out of control, CW-3000series water cooler possess a low flow alarm protection.

(2) ALARM DESCRIPTION

Causes of the cooling water circulation alarm and the working condition 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.

MAINTENANCE

Method of exchanging water in the water tank and the exchanging frequency

Method of exchanging water in the water tank

Drain the waste water out of the water tank through the drain outlet and fill the clean water into the tank through the filling hole

Exchanging Frequency

The purified water should be exchanged once a month and the running water should be exchange twice a month. The quality of the circulating water will directly influence the service life the laser tube.It is recommended to use purified water.

Application

S&A CW-3000 chiller for 3KW CNC spindle machine

Certificate

With 11 patent certificates and won Quality integrity Level A certificate;  ISO 9001, CE, RoHS and REACH environmental certificated. Conforms to air transport requirements, energy saving and environment friendly.

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 executed on each finished chiller.

Installation

It is very simple to install this industrial cooling machine. The first time installation of the new machine can be carried out by following steps.

Open the package to check if the machine is intact and all the necessary accessories are completed.

Open the injection port to feed cooling water. (Do not let the water spill over!)

According to system conditions, please connect the water inlet and outlet pipe well.

Plug in power, turn on the power switch. (Do not start up without water in the water tank!)   (1) Power switch turned on, the circulation pump of the chiller starts working. The first time of operating may cause more bubbles in the pipe leading to a flow alarming occasionally, but running for a few minutes later, it will go back to normal. (2) After the first boot, you must immediately check whether the water pipe leaks.

Check the water level of the water tank again. (It should be 80-150cm from the surface of water to the injection port)

Cautions

Please ensure that the power supply and electrical outlet are in good contact and the earth wire must be firmly grounded!

Please make sure there is stable and normal voltage for the working chiller!   As the refrigeration compressor is more sensitive to the power supply and voltage, so the operating voltage of our standard product is of 210 ~ 240V (110V model is of 100 ~120V). If you do need a wider operating voltage range, customization is available for us.

Unmatched power frequency can cause the chiller damage!   Please choose model of 50Hz or 60Hz according to actual circumstance.

To protect the pump, it’s strictly forbidden to run the chiller without water in the storage water tank!   The new machine is packed after draining whole water in the tank, so please make sure the tank has water inside before machine starting, otherwise it’s easily to have the pump damaged. To drain through circulating pump is strictly prohibited!

Please be sure that the air inlet and air outlet are in good ventilation!   There must be at least 30cm from obstructions to the air outlet which is in the back of the cooler, and should leave at least 8cm between obstructions and the side air inlet.

The cooling water must be drained if the cooler is out of use for long time or before being transported.

To protect laser heating devices , the radiator fan of cooler will suspend to work when water temperature is lower ( about 10℃ ) , and it will restart to run when water temperature rises to higher ( about 20 ℃).
