Hello All,

It's getting nice and toasty here in Southern Arizona, averaging 110 degrees, and our cooling system just can't keep up; we are currently using a radiator with a evaporative cooler providing the airflow. The local oil distributor swears up and down that Amsoil Synthetic has a lower internal friction and would reduce the heat generated by the pump. We are also looking at using a large water reservoir that should extend cutting time by at least two hours. Most of our jobs are small, one-off parts for prototypes so the waterjet use is fairly sporadic.
My questions are the following:

-Does anyone have recommendations for oil for high ambient temperatures?

-What cooling systems do you use?

Thanks!

-Paul

Hello Paul,

110F/43C is something we never encounter in the Netherlands, but our machines can be fitted with an optional oil/watercooler instead of the normal air/oil cooler.

I know this option is used when machines of our make are placed in the middle-east.

Cooling with water is much more efficient.

I have a lot more water coming to my water jet then needed, i think its like 12 gallons per minute, so it cools the pump much better. Visit my site you will see my work. http://www.vitabellasurfaces.com/
