SUPPLY CONNECTIONS
TUBING CONNECTIONS
The gas inlet and outlet is located on the top of the cooler and is indicated by arrows on the Jet- Stream heat
exchangers. For possible connectors see technical data. Corresponding tube or hose connectors are optionally
available by M&C.
I
t is the customer’s responsibility to select the correct impinger material that is best compatible
with their process gas. Do not mix up the hose connections; the inlet and outlet connections of
the heat exchangers are marked with arrows;
Ensure that the connections are sealed adequately;
To ensure free removal of the condensate, ensure that the listed diameters for the condensate
removal lines are not reduced.
Ensure that the connections are sealed adequately by noting the following:
•
Duran glass heat exchangers with connections GL 18-6 respectively GL 25-12
o
Before assembly, check the GL coupling rings to see if the PTFE/silicon locking rings have been
damaged.
o
The sealing rings should be installed with the PTFE side facing the process gas.
•
PVDF, Hastelloy or stainless steel heat exchangers with 1
/4“ NPT and 3/8“ NPT
o
Fittings or hose couplings corresponding to the correct NPT thread, with PTFE tape or sealing
compound are installed for connection to properly sized tubing or hose.
o
The heat exchangers with NPT threaded connectors are marked with circulated notches
indicating flow direction.
o
The NPT thread must be screwed in with sealant tape or compound.
Condensate drain connections at the bottom of the heat exchangers are made with the appropriate tubing
connector to the standard GL 25-12 tube connectors (Duran glass heat exchanger) or 3
/8“ NPT thread joint
(PVDF or stainless steel heat exchanger).
Condensate removal is provided by customer with:
•
Internal peristaltic pump
•
External peristaltic pump : M&C Series PP ;
•
Automatic float type condensate traps AD-... only for over-pressure operation;
•
Condensate collector container that is emptied manually.
