Spindle fluid chillers

gamme de refroidisseurs

8U Spindle fluid chiller (Refroidisseur de Liquide de Broche = RLB) range :

800 W to 2500 W.

Standalone groups with optimized dimensions for industrial process cooling.  

  • electro-spindle cooling for machine tools, lasers, robots, etc.
  • hydraulic power station cooling
  • air/water exchanger supply
  • electron microscope cooling
  • cooling and air conditioning of glove compartments
  16U - 20U Spindle fluid chiller (Refroidisseur de Liquide de Broche = RLB) range:
28 kW to 60 kW.
(If your application needs more power, we will design from your particular specifications.)
This range of chillers has a bigger tank. Consequently, inertia is greater and the cooled fluid reservoir (glycolated water, etc.) is larger.
  • rotary cylinder cooling
  • preforming mold cooling
  • laser, robot, spindle, etc. tool cooling
