Connecting The Moisture Detector (Option); Connecting The Peristaltic Pump (Option); Sample Gas Pump Connection Gas Lines (Optional); Connecting The Heat Exchanger - Buhler TC-Double+X2 Guía Rápida

TC-Double (+) X2

4.2.2 Connecting the moisture detector (option)

When ordering the cooler with moisture detector option, it
will be factory installed inside a flow adapter, or for the filter
option installed and connected in the filter head.

4.2.3 Connecting the peristaltic pump (option)

Coolers ordered with attached peristaltic pump already have
it installed and wired. Heat exchangers ordered at the same
time are already installed and connected to the peristaltic
pump.
The connection via the condensate outlet screw connection on
the pump must be carried out carefully and properly.
NOTICE
Installing peristaltic pumps CPsingle / CPdouble limits the
maximum permissible operating pressure in the system!
Operating pressure ≤ 1 bar

4.2.4 Sample gas pump connection gas lines (optional)

On coolers ordered with attached sample gas pump these are
already installed and wired. Add-on parts ordered at the same
time are already installed and connected to the sample gas
pump.
Avoid mixed-material installation, i.e. metal piping to plastic
bodies. If this cannot be avoided in isolated applications,
screw the metal connections into the pump body with care,
never use force.
Lay the lines so the line at the inlet and outlet remains flexible
for an adequate distance.
The pumps are marked IN for inlet and OUT for outlet at the
mounting ring. Be sure the gas line connections are tight.

4.2.5 Connecting the heat exchanger

To minimise gas wash out in the cooler, the two (identical)
heat exchangers must be operated in series. This should be
done as follows:
1. Gas inlet line to red gas inlet on heat exchanger no. 2 (pre-
cooling).
2. Connection between the heat exchanger no. 2 gas outlet
and the red gas inlet on heat exchanger no. 1 (after-cool-
ing).
3. Secure final gas outlet line to the heat exchanger no. 1 gas
outlet.

The gas inputs are marked in red.
On glass heat exchangers the correct position of the seal is im-
portant when connecting the gas lines (see image). The seal
consists of a silicone ring with a PTFE sleeve. The PTFE side
must face the glass thread.

4.3 Electrical connections

The operator must install an external separator for the device
which is clearly assigned to this device.
This separator
• must be located near the device,
• must be easy for the operator to reach,
• must comply with IEC 60947-1 and IEC 60947-3,
• must separate all live conductors and the status output,
and
• must not be attached to the power feed.
The mains supply of the device must be fused according to the
specifications under technical data.
Potential equalization/static charge
Static charges can result in incendive sparking. Avoid static
charges. Any conductive parts of the cooler must be groun-
ded!
The housing has a connection for an earth/equipotential
bonding conductor. Ensure the housing is adequately earthed
(minimum conductor cross-section 4 mm
