Installation Instructions for the
TBKA/TCKA, TBKC/TCKC Air Coolers,
GOLD/COMPACT
1. General
The TBKA/TCKA, TBKC/TCKC air coolers are used for cool-
ing the supply air with chilled water or evaporative refrig-
erant as the cooling medium.
The type TCKA air cooler is equipped with connections
for insertion-tpe sensors and can be used as a multi-pur-
pose coil (cooling and heating).
The air cooler must be installed for horizontal airflow.
The TBKA/TCKA, TBKC/TCKC air coolers are composed of
copper tubes and profiled aluminium fins.
The TBKA/TCKA has headers and water connections made
of copper/brass, with male connection threads.
The TBKC/TCKC has headers and distributor tubes made
of copper. The connections are designed for brazed joints.
Extra accessories
The TBVA Valve set consisting of a 2(3)-way valve includ-
ing actuator can be ordered. See the individual instruc-
tions for the TBVA valve set. If the air heater is to be
installed outdoors or in a cold space, take into considera-
tion the enclosure class of the actuator and the permis-
sible ambient temperature. If necessary, see to it that
required protection is arranged.
3. Maintenance
Check at least twice a year whether cleaning is necessary.
Cleaning shall only be done by blowing with compressed
air against the ordinary direction of airflow, vacuum clean-
ing with a soft nozzle or wet cleaning with water and/or
solvent. Before you begin wet cleaning, you should cover
adjacent functional sections to protect them. After wet
cleaning, you should blow the surfaces dry with com-
pressed air to remove every trace of cleaning solvent.
If cleaning solvent is used, this solvent must not contain
ingredients that will corrode aluminium or copper. Swe-
gon’s cleaning agent is recommended. This cleaning agent
is sold by Swegon or Swegon Service.
While cleaning, check the air cooler for tightness and that
the drainage pipework is not clogged. For the TBKA/TCKA
air coolers, also check the glycol content and vent the
circuit.

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.
