Temperature Control Units

Don’t allow your quality and productivity to rely on uncontrolled variables. Saint Clair Systems temperature control units seamlessly provide the required heating and cooling to achieve and maintain a +/-1°F material temperature at the point of dispense.

Saint Clair Systems temperature control units are totally self-contained, closed-loop, and balanced fluid process control systems. Expandable by controller to communicate to any line configuration, our proprietary thermal sizing tools ensure that the capacity of your temperature control unit is just right.

Proven Solutions - Proven Results

With over 3600 applications under our belt, we have the experience and expertise to streamline your processes and cut costs.

Case Study: Process Temperature Control

A potential customer was confident their processes were running fine and temperature control would offer minimal benefit.

So, we provided a free analysis of their systems using our proprietary software. We were able to show how differences in paint temperature were leading to excess coating. Our proposed solution saved over $500,000 in coating and solvent usage.

Water-Based Temperature Control System

Simple, balanced and efficient, these self-contained, closed-loop systems require neither additional plumbing nor an external water source. 

  • When heating is required, the immersion heater turns on
  • When chilling is required, a solenoid valve opens and exchanges water from the process with water from the chiller loop
  • Design ensures that the unit is either heating or cooling, but never both at the same time
  • The small increments required for heating or cooling and the use of water as the temperature control medium assure that the units use very little energy and are inexpensive to operate

For more than 25 years, Saint Clair Systems has created solutions for many types of applications and in many different industries. The compact, efficient, and economical AT-5900 is used in a variety of applications and offers an easy-to-use upgrade to many dispensing systems.

  • Available in either a single or dual version.
  • Enough heating and cooling capacity for many medium flow applications.
  • Interfaces easily with host controller systems and requires very little setup



Thermoelectric Temperature Control System

For systems that do not see significant swings in ambient temperature, but benefit from accurate temperature control, our thermoelectric systems offer an efficient and affordable option.

The device contains a Peltier chip. When an electric current runs through the chip, one side gets hot and the other side gets cold. Reversing the current makes the hot side cold, and the cold side, hot.

  • Based on the thermoelectric effect (also known as the Peltier effect)
  • Simple to operate
  • Controlling the current keeps very tight control on the process material


Multi-Station Recirculation Systems

When dispensing applications contain a large variety of options (as in a multi-color paint system), our solutions can provide temperature control for each circuit. This unit is capable of controlling up to three unique circuits.

  • Any combination of heating and cooling is available on one skid
  • Discrete control or PLC interface options are available
  • For use with remote-mounted heat exchanger systems, these units are compatible with all Saint Clair Systems heat exchangers, peripherals and chillers



Anti-Condensation System

Different from a traditional air heater, these units recirculate heated water to a heat exchanger mounted close to the source of the icing or condensation.

Traditional air heaters use air to transfer heat from outside of the booth to the bell. As air is a poor medium for heat transfer, these traditional air heaters are largely ineffective.

The benefits of these systems include:

  • Small and inexpensive
  • Wall-mount, heat-only unit
  • Stops condensation on paint bells and prevents icing of pneumatic pumps


StablINK System

  • Designed to eliminate process fluid variables by reducing temperature fluctuations
  • Minimize color variation
  • Maximize press operation speed
  • Decrease reliance on manual machine adjustments



Industrial Applications

For more than 25 years, Saint Clair Systems has been providing temperature control tools and solutions for industrial finishers that specialize in a number of areas:

Spray - 02 - Cropped

Spray Coating


Coil Coating


Adhesive Dispensing


Bell Anti-Condensation

We reported increased stability in striation patterns when applying PVC to aluminum to create a woodgrain finish. We reported significant reductions in color match issues as a result of consistent film build

- Alsco

Steelscape reported reduced “ropiness” when applying Polyester to steel resulting in a finish that “looks sprayed rather than rolled, Steelscape reported 75% reduction in solvent pop due to reduced solvent addition. Steelscape reported 100% reduction in solvents added to primers and backers and 60% reduction in solvents added to finish coats. This was the easiest capital project implementations that we’ve ever done!

As part of our ongoing continuous improvement plan at Roush, we decided to take a more aggressive approach to our temperature control in the paint shop. The resulting quality improvement was immediately noted and helped drive our FTC (First Time Capability) up and sustain it where we needed it to be.

At Valspar, we formulate our paints to run under a variety of different conditions and process variables. One of the primary variables is the paint temperature, which can vary from 40°F to 100°F based on the conditions at the coil coating facility. This wide swing in temperature can play havoc with both paint viscosity and application setup. Having consistent and targeted paint temperature removes this process variable and its effects from the equation. Additionally, having consistent paint temperature ensures optimal (minimal) usage of expensive reducing solvents to attain the desired viscosity and applied paint film thickness.

“Being able to control the temperature within a narrow range as paint is being used can be very beneficial. The most obvious benefit is a reduced amount of solvent usage. This is not only more economical for the coater but also reduces the environmental impact and health risks to their employees. Reducing the amount of solvent added [provides] additional benefit to the performance of the paint being used. The two major benefits are: Reduced possibility of having solvent popping or blistering problems. The addition of too much solvent to certain paints or certain colors of paints may cause color shifts or gloss changes and by reducing the amount that needs to be added this can be avoided.”
