Materials, Components &

Specifications

Control & Operation

The b-touch control panel regulates air volume, air velocity, discharge width

and temperature in either automatic or manual mode. It is connected to the

unit by a low-voltage data cable with RJ11 plugs. Multiple units are also connected

in this way.

Electric Connections

LPHW heated units are connected to the mains supply by a 2 metre cable with a

moulded, earthed plug.

The mains supply cable on electric heated units enters the air curtain via a cable

gland on the top of the unit. The cable is then connected to a terminal strip within

the unit. The water connections and low voltage connector plate are fitted to the

top of the unit to avoid the need for opening during installation.

Casing

The casing is made from zinc plated sheet steel and incorporates an inspection

panel. The inlet grilles have anodised aluminium grilles with fixed fins.

All casing components come in two standard colours - white (RAL 9016) or silver

aluminium (RAL 9006). Other RAL colours are available at an additional charge.

Motor/Fan Assembly

Units are supplied with two or more (depending on type) dual-inlet, vibration-free

suspended centrifugal fans driven b

y a two-side, suspended rotor motor. The fan

casing and impeller are made from zinc coated steel.

The motor is manufactured according to DIN 40050, protection class IP44 and

insulation class B. It is fitted as standard with thermal contacts which break the

circuit if the maximum motor temperatur

e is e

xceeded.

LPHW Heating Battery

The heating battery comprises copper pipes and aluminium fins and a water supply

connection with a G1”

female thr

ead.

The test pressure is 30 bars and the maximum operating pressure is 6 bars at

110°C.

Electric Heating Battery

The electric heating battery is made from aluminium fins and incorporates an

electronic control unit, complete with overload protection. When the unit is

switched off, the fans will continue to rotate until the fins have sufficiently cooled.
