Temperature Control Unit Monitors and maintains temperature for optimal coating material performance. ■ Coating materials are applied at optimal temperature. Material viscosity is controlled and will not be adversely affected by changes in plant temperature. ■ Materials can be heated or cooled to achieve optimal performance and coverage by raising ■ The microprocessor PID controller continuously indicates the temperature set point and process temperature. An RTD temperature sensor in the fluid stream automatically selects heating or cooling. ■ User-friendly controller includes temperature deviation alarm, front panel and external fault monitoring, loop break alarm and security lockout. ■ While the standard TCU operates a single heat exchange circuit, the system can be ordered with multiple channels of temperature conditioning. ■ Remote mountable heat exchanger The Nordson Temperature Control Unit provides an effective method to monitor and maintain material temperature by heating or cooling during can coating 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. This method provides very consistent control of the coating temperature. The Nordson temperature control unit can be customized to meet specific production requirements for size, heat exchanger mounting, and pump volume. Heating Capability The heating component of the temperature control unit helps to maintain consistent viscosity of coating material for proper film deposition and better operating efficiency and performance. Application of coating material kept at ideal temperature with water based coatings helps to improve flow and leveling characteristics for uniform coverage and reduced metal exposure. This can provide improved quality that minimizes reworks and production line stoppages. Further, proper temperature control can enable the use of lower spray pressures, which can reduce component wear and maintenance requirements to help ensure long service life.

Temperature Control Unit Electric Heater with High Temperature Safety During operation, water is heated by an electric circulation heater(s) located in the TCU unit. Since many coating materials are damaged by high temperature, this heater includes an adjustable high-temperature safety switch that will disable the heater circuit when the set temperature is exceeded, even if the controller is still calling for heat. Other features of the electric heater include maintenance-free water circulators, water reservoir with level switch, pressure and temperature gauges, and adjustable flow indicator....
