Point of Dispense - where temperature matters

Start With Point of Dispense

Point of Dispense is what separates Saint Clair Systems from all other forms of process temperature control.

Only Saint Clair Systems focuses on controlling temperature at the Point of Dispense.

For over 20 years, our patents, our solutions and our equipment have all been focused on getting the temperature consistent at the Point of Dispense.

Only Saint Clair Systems starts at the Point of Dispense and works backward.

 Measuring Material Temperature at Point of Dispense

One of the keys to controlling at Point of Dispense is being able to measure the paint temperature at Point of Dispense.

Saint Clair Systems uses a variety of temperature sensing devices (RTD's, thermocouples, thermistors, etc.) and selects the best fit for your application.

Our designs, including our patented Coaxial Hose Technology, use RTD's to measure the material temperature as close to the Point of Dispense as practical.

Working with Saint Clair Systems ensures that you are measuring actual material temperature, (not water temperature), at the Point of Dispense, (not at the TCU) for high accuracy and repeatability.

These devices send a signal back to the Temperature Control Unit which compensates with either heating or cooling to maintain +/-1ºF paint temperature at the Point of Dispense.

Control the Dispense Valve

There are instances where it makes sense to temperature control the dispense valve itself.

When required, Saint Clair Systems will design heat exchangers that fit directly onto the valve or help redesign the valve to accommodate water porting.

The picture below highlights a process that benefited from controlling the temperature of the dispense valve.

The customer had selected a dispensing temperature of 85° F.

During continuous operation, the process held steady at 85° F.

This particular process required an occasional 10-minute pause.

During the 10-minute pause, the material in the dispense valve drifted toward ambient, (in this case got colder).

The change in temperature that took place during that 10-minute pause created defective parts when the process started back up. We designed a heat exchanger for the dispense valve that held the material temperature at 85° F whether the process was running or paused.
