Adam, Unless the trap has been modified the water cooled part can be removed and replaced with an air cooled version. You can also just leave it in and have it not hooked up.Drive in's usually ran a narrow shutter which will give you a travel ghost indoor. Check shutter blades for 83 degrees fixed or adjustable. Set for 83 to 90 degree width. Some also used a high speed intermittent which will be noisy and require more film gate pressure to keep it steady. Trade off for regular one if you can. May have oil gauge and pick up for up angle at DI. May need to convert back to normal dowm angle set up. Castings and covers may be warped because of heat from large lamp. Good Luck Dick

I think that would depend on the size lamp you are using. You probably wouldn't need water cooling for a 2K bulb, but for 3K and up I think you'd be running into a heat problem without additional gate cooling. I've seen connections to a cold water faucet, with the water trickling constantly, exiting via a copper line into a sink. A better way is a recycling reservoir (old ones of iron, which rust, but new ones are plastic.) The pump is oil-filled and lies submerged at bottom, with clear plastic hoses replacing the heavy rubber and woven metal ones formerly used. Works well, the motor/pump unit lasts for years without any servicing. Anti-freeze added to the reservoir prevents algea, and blowing air through the hoses every several years wouldn't hurt if you must have something to do besides topping up the water level every couple of years.
