In this episode of Fix-It Friday! We teach you how to instal a Temperature Sensing Unit (TSU) on your PMC Heated Hose. An insulated jacket is included with your TSU compatible hose – you’ll want to ensure it is over the hose and in place before installing the TSU, as you cannot add it after the TSU is in place.
The equipment used today for spraying plural component urethane foam and coatings provide the means to preheat the A and R chemicals, pressurize the chemical to the manufacturer’s recommended PSI and deliver that conditioned and heated chemical to the gun via a heated hose. Most units today utilize a system which provides automatic hose heat. The proportioners are equipped with a controller which receives a signal from a temperature sensing unit. The signal indicates the temperature of the chemical in the hose from a remote distance from the proportioner and ideally just before the gun.
