Air is supplied into the space uniformly through the front panel of Halton Zen Rectagular, generally at a slightly lower temperature than the room air. The supply air flows down to the floor level, before gradually pervading the occupied zone at a low velocity. Finally the convection of warm surfaces causes the air to rise out of the occupied zone. The low velocity flow pattern is directed forwards.
The non-clogging unit can be easily opened and cleaned.
Halton PRA or Halton PTS/C can be used as an airflow adjustment damper in round duct sections. The safety distance for reliable air flow measurement from the displacement unit is 5 duct dimensions between displacement unit and air flow adjustment damper.
If air flow adjustment damper is installed closer to the displacement unit (minimum distance about 3 duct dimensions), supply air throw pattern is correct, but air flow measurement result will not be accurate. When installing air flow adjustment damper close to the displacement unit (minimum 3xD), attenuator could be needed between the damper and the displacement unit.
Note: The flow pattern data has been defined for a floor level installation.
Perform the installation for Halton Zen Rectangular in the following order:
A) Installation without base:
Fix mounting brackets(4 places) to the unit (1).
Position the unit (2) against the wall and secure with mounting brackets
(included in delivery).
Installation with base:
Fix the base (6) onto the floor and fix the unit (2) onto that.
Secure with mounting brackets on top (1) (2 places)
B) Fix duct cover sides (4) onto the wall between the unit and ceiling with
screws (not included in delivery) through cover.
C) After installation of the ductwork, install the front plate of the duct cover (5).
D) When multiple sections of duct covers are used, secure them with screws
(not included in delivery).
E) Install front plate of the low velocity unit (6).
Ceiling installation available as tailored solution. Please contact sales.
The supply flow rate is determined by measuring the differential pressure from the measurement nipple with a manometer.Use a measurement probe thin enough fit into the nipple. Then use tape or another gasket to create a seal in the nipple in order to get an accurate reading .
The flow rate is calculated by using the formula below:
The values of k factor for formula
(D = duct diameter; L/R, T, B = location of duct connection)

Code description
1. Front panel
2. Casing
Open the front panel (1) by carefully pulling the spring connections out.
If required, the flow equalization plate can be detached.
Wipe the parts with a damp cloth. Do not immerse in water.
Reassemble after cleaning in reverse order.
The Halton Zen Rectangular displacement ventilation supply unit is made of galvanised steel, polyester-epoxy-painted with a white (RAL 9003) colour.
The unit has a robust maintenance-free, non-clogging design.
The unit is comprised of a detachable, perforated front panel, an internal flow equalization plate, and casing.
The unit has a circular or rectangular duct connection on at the top, or a circular connection on the left/right side or back depending on where the unit is located.
Mounting brackets are included in the delivery, screws not.
The unit is equipped with a duct cover and/or installation base, where required.
The front panel of the unit is available of 1.5mm thick galvanised steel for demanding spaces.
