Components

1 Rotary heat exchanger is used when the

need for heat recovery is considerable. At the

same time it can recover humidity from the hot

extract air. It is very energy efficient and

requires limited space due to the short length.

Efficiency up to 85%, variable rotation speed

for adjusted efficiency, purging sector, plus

alarm if unintentional stop.

2 Counter flow heat exchanger is used where

there are special requirements of separation of

the airflows, example to avoid the transfer of

odours to the supply air. As humidity cannot be

transferred between the airflows it can be

used for dehumidification. Efficiency up to

90%, temperature sensor and modulating by-

pass damper ensures against ice building.

3 EC-motors, low energy consumption, good

control properties, high efficiency maintained

at small loads, low noise level and short length.

4 Supply and extract damper, air tightness

class 3 (EN 1751), aerodynamically damper

blades in extruded aluminum with rubber sea-

ling, steel rods and brass bearings, actuators;

on/off or spring-return (additional option).

5 Supply and extract filters, bag filters in filter

quality F7/F5 (EN 779), fixed with filter rails

that ensures the tightness requirements (EN

1886), handle for easy replacement, alarm

when the filters need to be replaced.

6 Hot water coil, designed for temperature up

to 100 °C and pressure up to 10 Bar. The coil is

secured against frost (additional option).

7 Integrated control system, installed from

factory. See page 5.

8 Casing complies with air tightness class L3,

has closed frame profile of steel and aluzinc

185 protected panels with 50 mm isolation.

9 Supporting legs, made from strong galvani-

zed steel and equipped with adjustable feet.
