3. Installation
For the installation of air coolers in duct systems, see the
individual instructions entitled: Installation Instructions for
Duct Accessories.
The capacity of the TBKA/TCKA air cooler is dependent
on the direction of airflow and correct connection of
the water pipes. Parallel-flow circulation will decrease its
capacity. For appropriate connections, see the figure. 1.
Use a pipe wrench to restrain the pipe connections of the
air cooler when tightening the external pipe connections
to avoid damaging the tubes in the air cooler. Always fill
the air cooler with liquid from the lowest connection. Vent
the air cooler before you commission it.
In the case of the TBKC/TCKC, the direction of airflow
has an insignificant effect on its cooling capacity. The air
cooler connections are designed for brazed joints. The
inlet cooling medium pipe should be connected to the
upper connection of the air cooler as shown in Fig. 2.
Connect the condensate discharge pipework across a
water trap to a drain gulley. A TBXZ-1-40 water trap is
available as an accessory. See individual instructions.
When connecting the condensate discharge pipework
of air coolers TBKA/TBKC with circular duct connections,
connect the pipework to the drainage connection at the
discharge air side of the air cooler. Blank off the drainage
connection at the inlet air side using a plug! See Figure 3.
Mix anti-freeze agent in the water to prevent the risk of
freeze damage in the TBKA/TCKA air cooler for chilled
water. If for some reason anti-freeze agent cannot be
used, take other measures to prevent freezing.
