Duran-Glass Heat Exchanger With Gl-Connections; Pvdf- Heat Exchanger With Pvdf-Tube Connectors - M&C EC-30C Instruction Manual

Connect the gas outlet of solenoid valve 1 on the right hand-side to the gas inlet of the
flow meter FM 40. Connect the outlet of the flow meter FM 40 to the gas outlet which
protrudes through the bottom plate of the cooler close to the front panel on the left-hand
side.
Connect the outlet of solenoid valve 2 (left) which protrudes through the bottom plate of
the cooler, in the middle, close to the front plate, to the fourth peristaltic pump.
If you are using three optional peristaltic pumps: Connect the heat exchanger outlets to
the peristaltic pumps. Each heat exchanger outlet will be connected to one peristaltic
pump at the front panel of the cooler.
Keep the tubing of the condensate outlets as short and structured as possible. The tubing
does not need to be connected in order.

8.6 Duran-glass heat exchanger with GL-connections

On mounting the glass heat exchangers, please follow these instructions:
Before mounting the GL connections, please check the PTFE/Silicone locking
„
rings for damages.
Mount the locking rings with the PTFE side facing the medium.
„
After assembly please check the leak tightness of the GL connections at the Duran glass
heat exchangers.

8.7 PVDF- heat exchanger with PVDF-tube connectors

Compared to Duran glass heat exchangers, the PVDF heat exchang-
ers have a lower heat conductivity. If you are using PVDF heat
Note
exchangers, please keep in mind, that the cooling capacity of these
heat exchangers are lower.
On mounting the PVDF heat exchangers with PVDF compression fittings, please follow
these instructions:
Carefully remove the nut from the screw-connection. Pay attention to the loose
„
ferrule inside the nut.
Push the union nut onto the 4/6 mm tubing.
„
Push the ferrule with the thick bulb facing the nut onto the tubing.
„
Push the tubing onto the support nipple in the screw-connection.
„
Tighten the union nut hand-tight.
