What Is The Process?

Using a jacket welded or wrapped around the vessel to cool the internal substance by passing chilled water continuously through the jacket.

Jacket Vessel Cooling Application Considerations

  • What is the product specific heat?
  • What is the maximum product start temperature?
  • What is the product end temperature?
  • What is the maximum product volume being cooled?
  • What is the required temperature of chilled water flow?
  • What is the required flow of chilled water?
  • What is the required pressure of chilled water?
  • What is the KW of the agitior motor?
  • What is the construction of the jacket and vessel?
  • What is the weight of the vessel?
  • Do you need anti-freeze protection?

Why Is Cooling Required For The Jacket Vessel Cooling Process?

To remove the heat inside the substance to the required temperature or to stop the heat caused by an exothermic reaction.

How To Calculate The Cooling

Product Volume (y) x ?T temperature difference (Z) x Specific Heat (kcals/kg°C)
÷ 860 + Agitator motor input = Cooling Duty for 1 Hour
If it’s over or under 1 hour then time also has to be taken into account therefore ÷ hours process to take to cool = Cooling Duty in KW
Plus weight of vessel kg x specific heat capacity of material of vessel kj/ kg°C x ?T temperature difference = kcals/hr ÷ 860 Cooling Duty for 1 Hour
If it’s over or under 1 hour then time also has to be taken into account therefore ÷ hours process to take to cool = Cooling Duty in KW

What Must The Cooling System Include?

Pressure in the jacket, if pressure is too high the jacket could split. To overcome this you can install a pressure relief valve or a pressure reducing valve. Jackets should be insulated if cooling water below 10C. The cooling system might have to have a bypass on the chiller or an external tank if cooling from high temperatures as the water could return as steam.
