what kind of chiller for an roboform 31

[blackdogmachine]

I recently bought a charmilles roboform 31. It was supposed to come with a chiller but it did not. What kind of chiller requirements are required for this machine. Does the edm circulate the oil through the chiller or do i need a chiller that has its own pump to circulate the oil. This will be the only machine that will be hooked up to the chiller. What kind of btu/hr required to keep the oil cooled? It is a 64 amp machine and most likely the pumps will generate most of the heat.


thanks in advance
