OMTech CW-3000 9L Industrial Water Chiller for CO2 Lasers up to 50W | 50W/°C heat dissipation | 9L reservoir | 5 L/min water flow | Digital temperature monitoring

Have been using this cooler for three years now, no problems. Would definitely recommend.

This Does NOT contain a freon type cooler. Its Fan ONLY BUT it does cool water to a few degrees above Ambient Temp. IE: it was 70 degrees in the shop and I ran a 15+ hr job on 110 V 2.2KW Spindle cutting OAK ( fairly hard wood ) . The RV Antifreeze got to 26 C or 78.8 F degrees. Before adding the cooler I could not get 2.5 hrs before Coolant temp was pushing 38C It works and works well. Pump is pushing MUCH more coolant than the pond pump that was included with the spindle kit. so far I am very pleased

My shark 3HP spindle was purchased with the Shark e-cool system. That system proved to be inadequate to maintain spindle cooling after 1 hour of operation. My research led to this unit. WOW this unit is doing a FANTASTIC job of keeping the spindle cool. After 2 1/2 hours of operation, the spindle maintained ambient room temperature. One note, this unit will cool to ambient temperature as no refrigeration is included. It has the aluminum radiator that is more than ample for the 3 HP spindle cooling. The fan moves ample air and coolant flow exceeds what my spindle can handle.(The unit is equipped with 10mm coolant connections that I had to reduce to attach to my 8mm spindle connections). I highly recommend this unit for CNC spindle cooling for those struggling with the inadequate Shark e-cool.

Plug and play. It just works. I am using it with a dual CO2 laser system so the dual in/out capability is very convenient.

Yes works great
