Gas sampling and gas conditioning technology 3-3.1-ME
Correspondingly tube and hose connectors are optional available by M&C .
N O T E !
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:
Borosilicate glass heat exchangers with connections GL18-6 respectively GL25-12 (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 6mm tube
resp. G3/8“I

For sample gas in- and outlet use a corresponding tube/hose connector (e.g. D6-DN4/6, part
no. 05V3115).

The correspondingly dimensioned tube respectively hose couplings for condensate outlet with
threaded connections G3/8 ” have to be screwed in with PTFE thread sealing tape.

To grant a functional and unproblematic mounting we recommend to use union pieces with
taper pipe thread type R according to DIN 2999/1 in connection with suitable sealing tape.
N O T E !
When fixing the connectors in the PVDF respectively stainless steel heat
exchanger hold up with a wrench at the pane of the bolt head!
Option: stainless steel heat exchanger with NPTi thread at the condensate outlet

The heat exchangers with NPT threaded connectors are marked with circulated notches at the
condensate outlet.

The NPT thread must be screwed in with sealant or fixed with adhesive.
In the standard configuration, the tubes for removal of condensate are connected directly to the heat
exchangers. These protrude with the GL25-12 tube connectors (standard, Borosilicate glass heat
exchanger) respectively with G3/8” (standard) thread joint PVDF or stainless steel heat exchanger
above the base plate of the cooler casing (fig.2). Condensate removal is done by customer according
to the type of operation with:

peristaltic pump(s) type SR25.2 implemented optionally in the cooler housing,

external mounted condensate vessel(s) with manually emptying respectively,

automatic float-type condensate traps type AD-... (only for excess pressure operation).
