Setting up Cooling Tanks

Stationary Engine

Traffic has been relatively light on the internet Stationary Engine mailing list this month, largely due to the big event in our annual calendar, the Tri-State Gas Engine Show at Portland, Ind. As one wit put it, within minutes of arriving at the showground, there was a group of friends from five countries the USA, Australia, England, Holland, and Pittsburgh! The range of engines and availability of parts at this show is unsurpassed, and even this year's rain failed to dampen the enthusiasm for a week of intense, engine related indulgence and socialising.

The Antique Tractor Internet Servicegroup (ATIS) was setup not far from the OFES (Oil Field Engine Society), and there was much visiting between the two, particularly as we had our first oilfield engine there, with one week to learn from experts how to start and run it before she is shipped to England. So this month's article is in recognition of the close friendships between ATIS and the OFES, being an answer to a question one list member posed concerning his Reid, although the information will equally apply to any tank-cooled engine.

As ever, the following comments reflect a variety of opinions that surfaced during this discussion.

I need some direction in setting up a cooling tank for a 15 HP Reid. The tank I plan to use is 5-foot tall, about 2-feet in diameter. What height in relation to the cylinder does the bottom of the tank need to be placed? Is there a certain length that the pipes exiting the cylinder need to be before they turn towards the tank? Do the pipes need to be horizontal, or level with the cylinder? At what level, or position, do the pipes need to enter the tank? Any help will be appreciated.

My opinion is that the pipe coming from the top of the cylinder to the tank should enter the tank below the water level in the tank, the pipe from the bottom of the tank to the engine should be near the bottom of the tank, and probably a drain valve at the bottom of the tank would be a good idea.

By keeping all pipes below the water level the water will thermosiphon, with hot water entering the tank at the top and cool water returning to the engine from the bottom of the tank.
