Notes concerning the operation of the exhaust waste vapour condenser
The exhaust waste vapour condenser enables an efficient condensation of the pumped vapours at the
outlet.
-
No backflow of condensates.
- Controlled recovery of condensates.
- Next to 100% solvent recovery.
- The isolation cover protects against glass splinters in case of breaking, acts as thermal isolation to
avoid condensation of humidity and is intended to absorb shocks.
• Assemble hose nozzles for coolant inlet and coolant outlet pipelines at the exhaust waste vapour
condenser.
• Attach the pipelines of the coolant circuit to the respective hose nozzles (hose nozzles 6 mm, see
image) at the waste vapour condenser.
• Check hose connections prior to starting operation of the cooling system.
• Secure coolant hoses at the hose nozzles (e.g. with hose clip) to prevent their accidental slipping.
• The gas outlet (hose nozzle 10 mm) must not be blocked. The exhaust pipeline has always to be free
and pressureless to enable an unhindered discharge of gases.
• If necessary connect the exhaust to a suitable treatment plant to prevent the discharge of dangerous
gases and vapours to the surrounding atmosphere.
• Attention: Install hoses of the cooling system in a way to avoid flow / dropping of condensed water onto
the pumping unit (especially cables and electronic parts).
• Ensure that the coolant outlet pipeline is always free and that it cannot get blocked.
• Maximum permissible coolant pressure at the exhaust waste vapour condenser: 6 bar (absolute)
Backflow always pressureless. Assemble a coolant valve always in front of the exhaust waste vapour
condenser (in the inflow).
• Comply with the maximum permissible coolant pressures of additional components in the coolant
circuit (e.g cooling water valve).
• Avoid overpressure in the coolant circuit (e.g. caused by blocked or squeezed coolant hoses).
• Permissible range of coolant temperature at the exhaust waste vapour condenser: -15°C to +20°C
• Check the overpressure safety relief device at the exhaust waste vapour condenser regularly, replace
if necessary. Check especially for conglutination and cracks.
• Avoid clogging of the exhaust waste vapour condenser due to deposits or freezing solvents, clean if
necessary or select a higher coolant temperature.
• In case of condensation: Check liquid level in both catchpots during operation. Do not overfill the
catchpots. Maximum liquid level approx. 80%, to avoid problems when removing the catchpot. Avoid
overflowing of the catchpot.
• Check liquid level in both catchpots regularly and drain condensate in time.
Removing the catchpot at outlet:
Remove joint clip, remove catchpot and drain condensate.
Reassemble drained catchpot.
Important: Comply with regulations when disposing solvents/condensates. Reuse if possible, purify if
contaminated.
