Any change in the specific melting temperature, and you will not get the required product.

What is the Temperature Controller Unit Circuit Configurations?

Following are the Circuit Configurations for Temperature Controller Unit

Direct Injection

It is the most simple configuration of all. This same source is used to fill the circuit and to put the fluid into the process. The mixing tank is then used to collect the fluid coming from the process.

The heater then works to heat the fluid if needed. Similarly, if it has excess heat it can be cooled to achieve the desired temperature.250°F (121°C) is the ideal temperature for this operation.


The closed-circuit configuration for the Temperature Controller Unit is similar to direct injection. It also uses the same source for process and cooling water.

It is done to compensate for the system loss or fill the circuit. In this cold water is not introducer rather a brazed-plate heat exchanger is used in the cooling of the process water. 300°F (148°C) is the ideal temperature for its temperature

Isolated Circuit

Like its name, it isolates the process fluid from the cooling fluid. The two-fluid remain completely separate which gives you the benefit of using two different fluids at the same time for cooling and processing. Ethylene-glycol is mixed in the process.

Isolated type of Temperature Controller Unit circuit configuration still makes use of a heat exchanger. The ideal temperature for isolated circuit configuration is 180°F (82°C).

What is the Importance of Turbulent Flow in a Temperature Controller Unit?

  • The Temperature Controller Unit needs to provide heat transfer fluid as well as turbulent flow at a proper temperature to maintain proper process temperature.
  • The fluid flows through the passage of mold and only the fluid that touches the cooling channel surface transfers heat and produces laminar flow.
  • Laminar flow in the Temperature Control Unit reduces the heat capacity as it is a smooth, constant, and clean stream. So turbulent flow is important to increase the speed of the fluid.
  • The increased speed allows the whole volume of fluid to touch the cooling surface and thus increases heat capacity.
  • Turbulent flow helps make the process efficient and provides a more even temperature.

Why do you Calculate Resins Loads for Selecting a Temperature Controller Unit?

  • The capacity of a Temperature Controller Unit depends upon the type of material used as every polymer materials have a different heat capacity.
  • If you are using different materials at a time, then the capacity of the Controller should be based on the material that takes the highest time to release heat.
  • 15 tons of cooling capacity per kW of the heating load is enough if your mold use got runners.

How to Install your Temperature Controller Unit?

  • Silicone oil is a better option for transferring fluid as its specific heat capacity is lower than that of water.
  • However, silicone hoses cannot be used because they dissolve over time.

The Thermal Fluid Quality

  • Make sure that the thermal fluid does not polymerize as it will lead to the blockade of the pipes.
  • The color of the thermal fluid is the indicator of its quality. If you see the color changing, it shall be immediately replaced as it will lose its efficiency.

Keep Plumbing

  • By plumbing through the bottom and removing all the air pockets, you can make sure that the flow is maintained.
  • The air pockets can damage the pump and also limit the flow.

Remove Dirt and Debris

  • Make sure that there is no debris or dust in the system by using a brush or a hoover.
  • This dirt, when accumulated, can restrict the flow, therefore it must be removed.

Keep it in a Spacious Area

  • It is necessary to provide the necessary space to the system for dissipating heat.
  • If the heat generated by the system is not dealt with properly, it will lead to poor efficiency.

Fix the Problems as Soon as They Appear

  • Make sure that you correct all the faults immediately so that there is no effect on the efficiency.
  • If a problem is not solved, it will lead to further complications.
