Nowadays, most newly built
houses are airtight. During re-building, most of gaps and holes are also made
tight in order to prevent undesired heat leaks. However, a natural air
circulation inside rooms is prevented this way, unpleasant smells cumulate and
mould might appear. It is necessary to ensure the essential air ventilation,
keeping the inevitable heat losses at a minimum level. This can be reached only
by using ventilation units with heat recovery. The unit has an inbuilt
heat-recovery heat exchanger in which the warm stale air transfers the most of
its heat to the cold fresh incoming air. Thanks to that, warm air is not let out
uselessly through an open window.
Two basic types of
ventilation heat recovery are available:
Central units of a
higher performance; air is distributed through pipes into individual rooms.
Local units
that are installed in a wall and ensure air ventilation for only the room they
are mounted in.
|
CENTRAL RECOVERY UNITS
The central unit will ensure an even air exchange in the whole building. The
unit brings fresh air into living areas like bedrooms or a living room via
pipes, and removes stale air from stressed rooms like lavatories, bathrooms or a
kitchen.
Central recovery unit AIR MINDER
AIR MINDER represents a new generation of wholehouse heat recovery and
ventilation systems. It combines continuous ventilation with the most
progressive heat recovery system on the market. It will effortlessly remove
polluted air and unpleasant smells from your kitchen, bathrooms and toilets and
provide a constant supply of clean filtered air, allowing you and your family to
live in an ideal indoor environment.
|
The optimum temperature comfort is kept and your heating cost
reduced. Continuous ventilation is thus ensured even when your house is sealed
(leaving for a holiday, or in recreation houses).
By keeping humidity levels low and introducing warmed fresh
filtered air to replace contaminated air, the quality of the internal
environment is significantly improved. Constant wholehouse ventilation can
reduce the relative humidity, which inhibits the ideal living and breeding
conditions of the house dust mite and mould spores. It is ideal for people who
suffer from asthma, allergy, and in homes with elevated indoor radon levels.
- Up to 93% efficiency of heat recovery,
- Low noise level.
- Low operating costs.
- Washable filters.
- It already meets future European directives for efficiency.

Remote controller:
Remote controller with LCD status screen. Automatically switches
between 3 speeds, slow (night), medium (day) and manually switchable
boost. Supplied with each Air Minder unit.
Simple installation:
AirMinder is the best in heat recovery, it is installer friendly and
fits into many different orientations with its unique ducting turrets
rotating to any required angle. Thanks to its simple construction based
on a mere clicking the modules together it can be easily mounted
horizontally as well as vertically. Remote controller with LCD status
screen. Automatically switches between 3 speeds, slow (night), medium
(day) and manually switchable boost. Supplied with each Air Minder unit

Central recovery
unit HR 100R
|
HR100 is a small-sized heat
recovery unit intended for ventilating either
apartments or just several rooms in single-family
houses. The installation is very easy thanks to its
small size and the unit will fit even into a very small
space (a cupboard, ceiling void). A 100mm piping is used
for air distribution. The system assembly with HR100R unit
is simple and fast.
- small dimensions
- low operating costs
- low noise level
- efficiency of 70%

LOCAL RECOVERY UNITS
Local Heat Recovery Units are intended esp. for houses that undergo
re-building and where only some rooms were made airtight, i.e. by window or
façade renewal. It is essential to use controlled ventilation for an optimum
comfort. A big advantage of these units is their easy mounting. The ventilation
units are mounted directly into a wall of the space in question, so no bulky
pipelines are needed, nor big building modifications.
Local recovery unit HR 25
HR25 Heat Recovery Unit is suitable for rooms that need intensive
ventilation, e.g. bathrooms, toilets, kitchens etc. During the
high-speed mode, this unit works partially with underpressure, i.e. it
sucks a bit more air from the room
than it lets in. This difference will ensure that air from such a room
will never spread into other rooms.
The unit works in two modes. The low-speed mode is suitable for
long-term ventilation, and the high-speed mode is intended for intensive
removal of stale, contaminated air and humidity.
Switching between
the low- and high-speed mode can be done either by a manual switch or
automatically by a humidistat, depending on the preset degree of
relative air humidity. Switching can be also wired to a light switch and
the high-speed mode can be switched on together with turning on a light.
Local recovery units HR 30W and HR 100W
These heat recovery units are suitable for ventilating living space like
living rooms, working rooms, bedrooms, and especially for open kitchens.
These units are well pressurebalanced, i.e. they bring almost the same
quantity of air inside a room as they exhaust. Sucking stale air from
other rooms is so prevented.
The HR 30W unit is equipped with a fine polyurethane dust filter of EU2
filtration class (suitable also for children‘s bedrooms).
Thanks to its possible higher performance, the HR 100W unit is suitable
also for poorly ventilated restaurants etc. Switching between the low-
and high-speed mode can be done either by a manual switch or
automatically by a humidistat, depending on the preset degree of
relative air humidity.
