Separation of condensate:
Attention: Due to electrostatics reasons the vapour condenser has no protec-
tive layer to avoid separation of condensed water! Risk of bursting!
• Maximum permissible coolant pressure at the vapour condenser: 6 bar (abso-
lute). Backflow always pressureless.
• Comply with the maximum permissible coolant pressures of additional compo-
nents in the coolant circuit (e.g coolant valve).
• Avoid overpressure in the coolant circuit (e.g. caused by blocked or squeezed
coolant hoses).
• Install an optional coolant valve always in the supply line of the vapour condenser
only.
Permissible range of coolant temperature at the vapour condenser:
-15°C to +20°C
Check hose connections prior to starting operation of the cooling system.
Check coolant hoses regularly during operation.
Do not allow the catchpots to get overfilled. Maximum liquid level approx. 80% to
avoid problems when removing the catchpots.
Check liquid level in both catchpots regularly and drain catchpots in time.
Removing the catchpots:
Catchpot / collecting flask at outlet:
Remove joint clip, remove catchpot and drain condensate.
Catchpot at inlet:
Admit air or inert gas (via pump inlet) to atmospheric pressure. Remove joint clip,
remove catchpot and drain condensate.
- Reassemble drained catchpots.
Important: Comply with regulations when disposing of solvents/condensates. Re-
use if possible, purify if contaminated.
For condensable vapours (water vapour, solvents, ...):
☞
Do not pump vapour before pump has reached its operating temperature and
without inert gas gas ballast.
☞ Use inert gas at the gas ballast to avoid the formation of explosive mixtures.
☞ With gas ballast ultimate vacuum will be reduced
☞ Do not pump vapour before pump has reached its operating temperature
In case of low boiling solvents when the formation of condensate is unlikely, the use
of gas ballast might be unnecessary.
☞
Operating the pump without gas ballast increases the solvent recovery rates at
the vapour condenser.
The exhaust waste vapour condenser enables an efficient condensation of the
pumped vapours at the outlet.
☞
Next to 100% solvent recovery.
☞ Install hoses for cooling water at the inlet and outlet (hose nozzle 6 mm), secure
hose connections against gliding down.
☞ Ensure that the system design does not allow the coolant outlet pipeline to be-
come blocked.
