About Sentry Sample Cooling Units

Sentry offers a wide variety of sample coolers with a choice of heat transfer area, materials of construction and shell design.

Standard sample tube sizes are:

1/4" diameter in lengths of 19 and 38 feet (5.8 and 11.6 meters)
3/8" diameter in lengths of 19, 38, and 50 feet (5.8, 11.6 and 15.2 meters)
1/2" diameter in length of 20 feet (6 meters)

The standard tube material is 316 stainless steel. Optional materials are available for handling fluids which are not compatible with stainless steel. Inconel 625 is used when chlorides are present in the cooling water or sample. Exotic alloys such as Hastelloy, Titanium and Monel are available for severe service applications. The standard shell material is 304 stainless steel with cupronickel as a option.

The TF series is the most commonly used shell configuration for applications in power plants and the petrochem industry. It is the most compact of the high pressure models and has cooling water connections top and bottom to facilitate piping into a central panel. The FLF series provides larger heat transfer capacity, and all four connections are on the top so that the shell can be removed without breaking any connections. The WSW model has a all welded shell with a 1/2" tube. It is commonly used in process sampling or gases and more viscous fluids. The TRB-4222 is used for sampling water from heating and industrial boilers.
