Cold Capillary Thermostats Selco's WK and WP series of thermostats provide a wide variety of functions designed specifically for refrigeration, freezers and air conditioning applications. This series offer accurate temperature control and narrow differential. Form, fit and function drop in replacement to many OEM controls. These are mechanical switching devices that are activated by temperature change in the capillary tube sensor. This sensor is charged with a special refrigerant gas selected for the application. This change is converted to travel via the bellows/diaphragm actuated by the mechanical level switch closing on temperature rise. The switch typically controls a compressor or other refrigerating components. Thermostats can also be charged with a special hydrocarbon with is basically safe to the environment.
