Wax-bulb actuator
The TCA (D355…630mm) can be equipped with a waxbulb
actuator. Neither auxiliary energy nor dedicated
control system are needed.
The actuator position changes according to the
temperature of supply air.
When warm air is supplied at a temperature up
to 18°C, the wax bulb actuator piston moves
progressively until the conical central core is at the
low position. The supply air pattern is vertical compact
jet.
The cycle for movement between extreme positions
takes 10 to 20 minutes.
When cold air is supplied, the conical central cone
is returned back by springs to the upper position for
horizontal radial jet function.
The operation range of the wax-bulb actuator is
between 18°C and 32°C.
No maintenance is required for the wax-bulb actuator.

Radial Jet
Function
Supply air is supplied into the space through cones,
either horizontally along the ceiling (ventilation or
cooling application) or vertically (heating application).
The supply air mixes with the room air around the
diffuser.
The adjustment from the radial jet position to the
compact jet position can be performed either manually
or by using an electric or wax-bulb actuator.

Installation
CODE DESCRIPTION
1 Conical central core
2 External cone
The TCA diffuser can be installed flush with a
suspended ceiling or fully exposed in the space.
The diffuser is connected either directly to the duct or
using a PLC plenum or TRI balancing plenum.
When connected directly to ductwork a safety
distance of minimum 3xD upstream of the diffuser
should be maintained.

Adjustment
CODE DESCRIPTION
1 plenum box plc
2 Measurement and adjustment
Part (MSM)
The airflow rate can be adjusted and measured only
when the diffuser is installed.
In order to enable airflow adjustment and
measurement of the airflow rate, it is recommended
that the diffuser be connected to the plenum
equipped with the MSM module.
The supply flow rate is determined by using the
measurement and adjustment module MSM.
Unscrew the conical central core and pass the tubes
and control spindle through the diffuser.
Measure the differential pressure using a manometer.
The flow rate is calculated using the formula below.
q
v
= k *
p
m
Adjust the airflow rate by rotating the control spindle
until the desired setting is achieved.
Lock the damper position with a screw.
Replace the tubes and spindle into the plenum and
replace the central cone.
K factor for installations with different safety distances
(D= duct diameter)
Airflow adjustment damper DC
The airflow rate is adjusted by turning the damper
blades behind the diffuser with a screwdriver. The
measurement is carried out when diffuser is installed.

Servicing
Remove the conical central core by gently drawing it
out by the central core.
Clean the parts by wiping them with a damp cloth.
Push the conical central core back into place so that
the springs lock.
Option: with balancing plenum TRI + MSM or PLC
+ MSM
Remove the measurement and adjustment module by
gently pulling the shaft (not the control spindle).
Wipe the parts with a damp cloth, instead of
immersing in water.
Reassemble the measurement and adjustment
module by pushing the shaft back into place until the
module meets the stopper.
Push the diffuser back into place so that the springs
lock.

Vertical throw pattern with non-isothermal air
Vertical throw patterns shown in the diagrams are
based on isothermal air. When heated or chilled jets
are considered, the distance of projection changes
due to air density.
Throw patterns using different input data can be seen
calculated precisely using the Halton HIT Design, or
the table below to determine the projection factor.
Multiply the factor by the isothermal throw pattern
(L0.2) to determine estimated projection distance:
