5.2.1. Tubing
Recommended tubing:
Maximum pressure
Textile-reinforced tubing > 4.5 bar
Warning: Tubing:
At high working temperatures, the tubing used for temperature control and for the
cooling water supply represents a danger source.
A damaged tubing line may allow a large amount of hot bath fluid to be pumped out
within a short time.
This may result in:
 Burning of skin
 Breathing difficulties due to hot atmosphere
Safety instructions
 Use suitable connecting tubing.
 Make sure that the tubing is securely attached.
 Avoid sharp bends in the tubing and maintain a sufficient distance from
surrounding walls.
 Regularly check the tubing for material defects (e.g., for cracks), at least once a
year.
 Preventive maintenance: replace the tubing from time to time.
5.2.2. Bath fluids
Caution:
Carefully read the material safety data sheet of the bath fluid used, particularly with
regard to the fire point!
If a bath fluid with a fire point of
 65 °C is used, only supervised operation is
possible.
Water:
The quality of water depends on local conditions.
 Due to the high concentration of lime, hard water is not suitable for temperature
control because it leads to scale in the bath
 Ferrous water can cause corrosion, even on stainless steel.
 Chlorinated water can cause pitting corrosion.
 Distilled water and deionized water are unsuitable. Their special properties
cause corrosion in the bath, even on stainless steel.
