U-Tube Recovery Unit (UTR Series)

The UTR is installed on gas engines: reciprocating, turbo charged, naturally aspirated, and rotary, as well as diesel engines. This Cain economizer is typically used to heat engine jacket water, process water, boiler water, ethylene glycol, and thermal transfer fluids.

The UTR can be located within the engine to meet crucial space limitations. There are 44 standard models available for selection that can fit the most compact space. The exhaust gas connection sizes and locations provide for installation flexibility, the UTR can adapt easily to an OEM packager’s design needs.

The core assembly can be removed without disturbing the exhaust gas connections, makes cleaning and inspecting the finned tubing efficient. This is especially important when the combustion source uses fuel oils that more easily foul the heating surfaces.

The rugged heat transfer core is made from SA178 boiler tubing and .25” thickness high-grade carbon steel heater assemblies. The heat transfer materials can also be constructed of all stainless steel when exhaust temperatures entering exceed 1250°F or when liquid temperatures entering are below 120°F. Insulation is available in varying thickness as requested.

Combustion Capacity: 15 to 300kw

Entering Gas Temperatures: to 1600°F
