What Is The Process?

Metal products that have been heated in a furnace need to be cooled in water quickly to ensure that the material is hardened (tempered).

Usually there is a large tank of water that starts at a temperature and is heated quickly by the piece of metal.

Normally the tank is allowed to a set level it must not rise above this and this must be allowed in the calculation.

Quench Tank Cooling Application Considerations

  • What is the temperature of the chilled water required?
  • What water pressure do you require at the tools?
  • What is the plastic throughput per hour?
  • What type of plastic is being used?
  • What is the in/out differential?

Why Is Cooling Required For The Quench Tank Cooling Process?

Roll cooling is required to take the heat out of the plastic. These roller can be temperature controlled, they can require cooling at different temperatures. They are designed to change the plastic from a soft state to a harden state. Flow rate through the rolls can be very high!

What Must The Cooling System Include?

Some of the larger machines have temperation units on them and therefore require low pressure pumps but also have low temperature differences and therefore a buffer tank with separate process and chiller recirculation pumps is advisable. On smaller systems a manual By-Pass on chiller circuit is acceptable. It is likely the water flow could change during operation so it if important the chiller always has its required minimum flow.

A lot of these systems apart from APET can run at 25C water supply therefore ambient cooling products could be applied.

How To Calculate The Cooling

Tools = Plastic through put x Plastic Factor = Cooling Duty in KW
