Agilent Varian Turbo Water Cooling Kit With Metal Hose Barbs, Fits Most Agilent Compact Turbo Molecular Pumps, PN: X3502-68002

These Agilent Varian TwissTorr turbo pump water cooling kits are metal with plastic water line connections. They are designed to mount to the bottom of the Agilent TwissTorr turbomolecur vacuum pumps. A water cooling kit is used under heavy load conditions or when air cooling is insufficient. The assembled kit must be screwed into the suitable holes of the pump body with a recommended closing torque of 5 Nm (3.69 ft/lb). Cooling may be carried out either through an open circuit with eventual discharge of the water, or using a closed circuit cooling system. The water temperature must be between +15 °C and +25 °C, with an inlet pressure between 2 and 4 bar. This allows a flow higher than 65 l/h.

NOTE: The water electrical conductance must be ≤ 500 μs/cm. When the conductance is higher, in closed water circuit, the use of up to 20% of Ethyl-Glycole is suggested. These kits include the hardware needed for proper installation to the TwissTorr turbo pumps and have Agilent Varian part number X3502-68002. The installation instructions can be found by downloading the pdf catalog and documents below.
