AT-5900 Temperature Control Unit

Monitor & maintain material temperature during painting, finishing, or coating operations.


The AT-5900 Temperature Control Unit provides an effective method to monitor and maintain material temperature by heating or cooling fluids during operations.

The TCU heats, cools and circulates the closed-loop conditioning water through heat exchangers and ancillary components to ensure proper temperature of the coating material throughout production.

A temperature sensor located in the coating fluid stream sends the material temperature to the PID controller, which automatically determines whether heating, cooling, or no action is required.

The AT-5900 temperature control unit can be customized to meet specific production requirements for size, heat exchanger mounting, and pump volume

Eliminate the Costly Effects of Temperature Variations Occurring During the Day or Between Seasons.


As temperature increases, viscosity decreases and vice versa. While automotive and industrial pain has a magnitudinal shift from 50-350 cps, the for sealers & adhesives is much higher: running from 30,000 to 1 million cps!

What’s more, this change happens right in the middle of the ambient range - between 18 & 26C. If you’re having trouble with your sealer application, temperature could very likely be the culprit.
