NARAH 160 ventilation unit with heat recovery

Casing

is made from durable, white, hardened plastic. The part of the unit containing the heat exchanger allows for installation in an external wall with a thickness of 250–490 mm (for thicker walls, installation is possible using an extension pipe 500 or 700 mm in length). The interior of the unit is fitted with a stylish front panel featuring a digital display for unit control.

Fan

The unit is fitted with a reversible axial fan with a DC motor. The fan is designed for continuous operation.

Motor

Brushless motor with electronic control and low power consumption.

Regeneration

The unit is fitted with a regenerative heat exchanger made of ceramic material. It achieves a heat recovery efficiency of up to 95 per cent. For easy maintenance and servicing, the heat exchanger is accessible after removing the unit’s internal cover.

Filters

A G3-class filter (ISO coarse 60 per cent) is fitted on both sides of the heat exchanger.

Installation

The unit is designed for indoor wall mounting. The unit may only be installed with the heat exchanger body in a horizontal position, with a minimum slope of 1 per cent towards the outer edge of the wall. The telescopic duct containing the heat exchanger, fan and filters can be adjusted to suit wall thicknesses ranging from 250 to 490 mm. For thicker walls, the 250 mm section of the telescopic duct, which is included as standard with the unit, can be combined with an extension duct measuring 500 or 700 mm. When using the 700 mm duct, the unit can be installed in walls up to 940 mm thick. The unit is also supplied with an internal designer cover featuring a digital display and an external façade grille.

Electrical connection

A three-core 230 V / 50 Hz power cable is connected to the unit.

Control

The unit features a fully automatic mode which, based on an integrated humidity sensor, ensures smooth speed control without the need for any further intervention in the unit’s operation. It is also possible to control the unit manually. The stylish remote control (included) allows you to set the ventilation intensity to one of four levels, select ‘supply only’ mode, ‘night-time silent’ mode and ‘by-pass’ mode. In the standard supply and extract alternation mode, the airflow change interval is set to 60 seconds. Up to 4 units can be synchronised wirelessly without the need for any additional accessories. The unit can also be controlled using wireless air quality sensors from the AIRSENS RF.2 series, or a wireless BOOST RF.2 button can be added to the unit.
