Silicone Rubber Heater Solves Dairy Truck Freezing Problems


The dairy industry requires remote bacteria testing for collected milk. However, in the winter season the sampling valve on the customer's milk truck would freeze closed.


To solve this problem, Watlow designed a pre-formed, custom-shaped silicone rubber heater with an insulated jacket with Velcro straps for easy removal during daily valve cleaning. Another unique features was a thermostat to control critical upper and lower temperature ranges.
