Temperature control

 

We offer cooling or heating media to maintain, heat or cool liquids at a constant temperature. Two different processes are used:

1. endless coil with a defined laminar or turbulent flow

2. double jacket or templates.

A double jacket is welded at certain points distributed over the entire surface. Under high pressure, cushions are formed at the non-welded points, into which coolant is filled.

 

Cooling zones

Different media can be used to cool the contents of a tank:

1. ice water: Whereas ice water used to run over the tank as trickle cooling, today it is the water in an endless spiral that provides the cooling.

2. glycol: When rapid cooling is required, glycol is often used, which offers a great advantage over water: the freezing point can be extremely lowered without the liquid freezing.

3rd ammonia: This agent is sprayed into the cooling zone in liquefied form, which causes the coolant to relax and attempts to become gaseous again.

The result: Ammonia absorbs cold in large volumes.

Disadvantages of ammonia:

  • The agent is life-threatening.
  • The increased pressure requires a thicker coating.
  • Expensive procedure
  • The cooling circuit cannot be precisely regulated

Heating zones

Different media can be used to heat the contents of a tank:

1. hot water:

Hot water is transported in a spiral surrounding the tank. The heat supply is possible until shortly before the degree of evaporation (80 - 90 degrees).

2. Steam:

Steam achieves a higher output than hot water. Water is heated until it evaporates. It is then passed through a coil or template. Although steam has a higher output than water, there are limits here too. The output is 120 - 150 degrees.

3. thermal oil:

Thermal oil can be used to achieve a higher output than steam. The heating temperature to be achieved can reach 250 - 300 degrees. However, these high temperatures must be taken into account when selecting the material, because otherwise material deformation can occur when the heat is high.

4. electric heating:

An electric heating band - similar to an underfloor heating system - heats the tank liquid. Similar to hot water heating, temperatures of around 80 - 90 degrees can also be achieved here.u
