Follow these instructions to ensure the adequate sealing of the connections:
Borosilicate glass heat exchangers with connections GL 18-6 respectively GL 25-12 (standard)
•
Before assembly, check the GL coupling rings to see if the PTFE/silicon locking rings have been
damaged.
• The sealing rings should be installed with the PTFE side facing the medium.
PVDF- resp. stainless steel heat exchangers with G 1/4“ i resp. G 3/8“ i
• The fitting tubing or hose couplings with threaded connections have to be screwed in with PTFE
thread sealing tape.
•
For a functional and smooth mounting, we recommend using union pieces with tapered pipe
thread type R according to DIN 2999/1 in connection with suitable sealing tape or fluid.
Note
To tighten the connectors onto the PVDF or stainless steel heat exchanger, hold
a wrench against the spanner flats of the bushing!
Option: stainless steel heat exchanger with NPT
•
The heat exchangers with NPT threaded connectors are marked with a notch around the
connecting pieces.
• The NPT thread must be screwed in with sealant or glued in with adhesive.
In the standard configuration, the tubes for condensate removal are connected directly to the heat
exchangers. These protrude with the GL 25-12 tube connectors (standard, Borosilicate glass heat
exchanger) respectively with G 3/8” (standard) thread joint PVDF or stainless steel heat exchanger out
of the bottom plate of the cooler housing (fig.2).
The condensate removal is customer specific and depends on the type of operation:
•
peristaltic pump(s) type SR25.2 optionally mounted into the cooler housing,
• external mounted condensate vessel(s), which needs to be emptied manually respectively,
•
automatic float-type liquid drainer type AD-... (only for over-pressure operation).
Note
If using a stainless steel heat exchangers with G 3/8” thread, the float-type
automatic liquid drainer AD-SS can be directly monted to the heat exchanger by
using the threaded adapter part number FF11000 (1/2” NPT to G 3/8” i). In this
case wall mounting and tubing of the AD-SS unit isn’t necessary!
