DTS Digital Heat Trace Thermostat for Epoxy Flow Regulation

industrial coating process heating and controls

The Challenge

An international manufacturer of epoxy industrial coatings spray systems sought help in reducing the footprint and expense of the control system that maintaining minimal system temperatures. These temperatures are critical, providing proper viscosity that allows the epoxy to flow at the proper rates. Another heat critical factor: epoxy coatings have a short 'pot life', meaning that the coating must be applied within a prescribed amount of time or the batch becomes unusable.

The Solution

Chromaloxs new DTS Digital Heat Trace Thermostat provided the solution, taking up 25 percent of the space needed by the control panel, and reducing production costs by nearly 60 percent in the skid-mounted epoxy spray systems. The DTS provides temperature control from the systems compressor to the nozzles, maintaining minimum temperatures to provide proper flow rate and eliminate clogging. It also provides existing process temperature information, plus high and low temperature alarms and sensor failure alarms. The solution allowed the manufacturer to add a 'soft start' function to the spray systems, reducing the size of the power supplies and adding another cost benefit.
