GENERAL - HD

HIGH WALL FAN COIL UNITS - HD

Comfair HD fan coil units are similar in design and use to the widely
used DX high-wall mini-split systems. With a maximum width of only
210mm, the casing is manufactured from high quality plastic and
is of an aesthetically pleasing design to compliment almost every
environment.

«A BREATH OF FRESH AIR»

The fan is of a Tangential type running at low speed to guarantee
low noise levels. The concept of air discharge from the unit allows
effi cient distribution of the treated air for maximum comfort, and
simplicity of use. HD units are equipped with a system of automatic horizontal air defl ection through an arc of 35° in cooling operation
(10° in heating operation), which avoids stratifi cation of the airstreams. When the unit stops, the defl ector blades close automatically,

which serves not only to protect the internal components against dust but also preserves the
neat aesthetic appearance of the unit.

FILTRATION AND AIR QUALITY

The Comfair HD units not only control the temperature of the air but also the air quality in the
conditioned space. Each unit is fi tted with a fi lter and an Ioniser which produces negatively
charged ions which attracts the positively charged dust particles and neutralises harmful
microbes present in the atmosphere. The Ioniser comprises of a small generator, which transmits
an intermittent high voltage to carbon fi bres situated in the airstream.

COILS

Each unit contains a chilled and hot water coil manufactured from copper tubes with aluminium fi ns. Water connections are female gas
½» and each coil is fi tted with an air vent. A water temperature sensor prevents low temperature discharge.

REMOTE CONTROLLER

The infa-red remote controller offers the same functions as a DX split system. It includes an LCD display which indicates the status
and set points of the unit. Sixteen buttons allow fast and easy control of the operation of all functions of the unit.
