Laser machine cooling solution

EURODIFROID conducted a chillers retrofitting project with range ECB water cooling devices, which were fitted into a specific frame "electrical cabinet" like, in order to optimize the space required on the floor.

EURODIFROID solution

*Datas given at 10°C water outlet, 32°C ambient temperature
Product ECB 400 TWI and ECB 900 TWI
Quantity 10 units
Cooling capacity* 25 kW et 70 kW
Technology Water cooler condenser water

Installed equipment

Design illustrations below (3D views) allow to have a preview of the EURODIFROID machine and the potential benefits of an integrated approach in the cabinet:


  • Small footprint
  • Accessibility of components
  • Full dismantling of the side panels and rear
  • Robust and bearing structure


EURODIFROID relies on its capacity to adapt a "standard" machine to complex industrial application (in this case, dirty water)

EURODIFROID advantages: Option monitoring fouling:

The fouling of the condenser is followed by a measurement of pressure losses in the condenser. The "monitoring fouling" option consists of the following components:

 

  • 1 differential pressure switch with upstream and downstream pressure tap
  • Actuating a dry contact to lift a fault "clogging"
  • The fault is adjustable (by pressure difference Maximum permissible nominal operation of the cooler)


This fault will light a red light to alert maintenance teams that maximum is exceeded and fouling a cleaning operation is required.
