  • Low velocity air is supplied horizontally at the floor level.
  • Suitable for installation in the corner of a room; the airflow pattern is diffused at an angle of 90 degrees.
  • If ceiling installation (not recommended) is required, please contact sales.
  • The detachable front plate and metallic internal structure enable cleaning of the unit and ductwork.
  • Circular duct connection with an integrated rubber gasket on top/bottom.

Product models and Accessories

  • Model with stainless steel (AISI 316) design
  • Model with thick front panel (1,5 mm)
  • Duct cover
  • Installation base

The Halton Zen Corner displacement ventilation supply unit is made of galvanised steel, polyester-epoxy-painted with a white (RAL 9010) colour.

The unit has a robust maintenance free, non-clogging design.

The unit is comprised of a detachable, perforated front and inner panel, an internal flow equalization plate, and casing.

The unit has a circular duct connection at the top or bottom, depending on the location of the unit.

Mounting brackets are included in the delivery, srcews not.

Options

The unit can be 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.

Function

Air is supplied into the space uniformly through the front panel of Halton Zen Corner,
generally at a slightly lower temperature than the room air. The supply airflows 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 quarter-circular (90° ). 

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 airflow measurement from the displacement unit is 5 duct dimensions between displacement unit and airflow adjustment damper.
If airflow adjustment damper is installed closer to the displacement unit (minimum distance about 3 duct dimensions), supply air throw pattern is correct, but airflow measurement result will not be accurate. When installing airflow 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 floor level installation.  

Installation

Perform the installation the following order:

A)   Installation without base:
           Fix mounting brackets (4 places) to the displacement ventilation unit (1). 
           Position the unit (2) against wall and secure with mounting brackets
           (included in delivery).

       Installation with base:
           Fix the base (6) onto the floor and fix the displacement ventilation unit (2)
           onto that. Secure with mounting brackets on top (1) (2 places).

B)   Fix displacement ventilation unit duct cover frames (4) onto the wall between
       the unit and ceiling with screws (3).

C)   After installation of the ductwork, install the front plate of the duct cover (5).

D)   When multiple sections of duct covesr are used, secure them with screws
      (not included in delivery).

If ceiling installation (not recommended) is required, please contact sales.

Adjustment

The supply flow rate for displacement ventilation unit 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:

Servicing

Code descprition
1.    Front panel
2.    Inner panel
3.    Casing

Open the front panel (1) by  carefully pulling the spring connections out.
Open the inner panel (2) by unscrewing the screws.If required, the flow
equalization plate can be detached.

Wipe the parts with a brush or damp cloth. Do not immerse in water.

After cleaning, reassemble in reverse order.
