Silicone Rubber Heater Solves Dairy Truck Freezing Problems

Problem:

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.

Solution:

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.
