Temperature Control Unit

nnnn

Monitors and maintains temperature

nnnn

for optimal coating material performance.

nnnn

Features and Benefits

nnnn

■ Coating materials are applied at optimal temperature.

nnnn

Material viscosity is controlled and will not be

nnnn

adversely affected by changes in plant temperature.

nnnn

■ Materials can be heated or cooled to achieve

nnnn

optimal performance and coverage by raising

nnnn

or lowering viscosity.

nnnn

■ The microprocessor PID controller continuously

nnnn

indicates the temperature set point and process

nnnn

temperature. An RTD temperature sensor in the

nnnn

fluid stream automatically selects heating or cooling.

nnnn

■ User-friendly controller includes temperature

nnnn

deviation alarm, front panel and external fault

nnnn

monitoring, loop break alarm and security lockout.

nnnn

■ While the standard TCU operates a single heat

nnnn

exchange circuit, the system can be ordered with

nnnn

multiple channels of temperature conditioning.

nnnn

■ Remote mountable heat exchanger

nnnn

The Nordson Temperature Control Unit provides an effective

nnnn

method to monitor and maintain material temperature by

nnnn

heating or cooling during can coating operations. The TCU

nnnn

heats, cools and circulates the closed-loop conditioning

nnnn

water through heat exchangers and ancillary components to

nnnn

ensure proper temperature of the coating material throughout

nnnn

production. A temperature sensor located in the coating fluid

nnnn

stream sends the material temperature to the PID controller,

nnnn

which automatically determines whether heating, cooling,

nnnn

or no action is required. This method provides very consistent

nnnn

control of the coating temperature.

nnnn

The Nordson temperature control unit can be customized to

nnnn

meet specific production requirements for size, heat exchanger

nnnn

mounting, and pump volume.

nnnn

Heating Capability

nnnn

The heating component of the temperature control unit helps

nnnn

to maintain consistent viscosity of coating material for proper

nnnn

film deposition and better operating efficiency and performance.

nnnn

Application of coating material kept at ideal temperature

nnnn

with water based coatings helps to improve flow and leveling

nnnn

characteristics for uniform coverage and reduced metal exposure.

nnnn

This can provide improved quality that minimizes reworks and

nnnn

production line stoppages. Further, proper temperature control

nnnn

can enable the use of lower spray pressures, which can reduce

nnnn

component wear and maintenance requirements to help ensure

nnnn

long service life.
