Ventilations is a pure necessity. Unfortunately some people
tend to forget! Insufficient ventilation can cause serious
damage in a building. Fungi and woodrot can cause
permanent deterioration of the construction (In the
Netherlands alone, this type of damage accounts for many
tenths of millions of Euro).
Allergenic and hazardous substances in too high
concentrations-- are perhaps an even more serious threat
with severe consequences for your health.
Ergo, you can never have enough fresh air. But there is a
snag. Ventilation also requires energy, not only to run the
fans but especially because fresh air is also cold air that
needs to be heated to room temperature. In modern
buildings these so-called 'ventilation losses' may account to
as much as 50% of the total heating costs. Because of this,
modern or refurbished houses are usually as air-tight as
possible and the inhabitants are stuck with a dilemma:
“How do I get a good indoor air quality without wasting
energy?
ClimaRad is your answer! It provides healthy ventilation
and it saves energy.
CO , Indoor Air Quality and ClimaRad

People produce CO and humidity through breathing. In
2
occupied, badly vented rooms the CO -concentration will
2
increase rapidly. High concentrations of CO are not

damaging on the short term, but they create a damp and
smelly indoor climate. If people stay in such a climate for a

longer period it may irritate eyes, throat and nose. Also,
most obvious at work or school, higher CO concentrations
2
are known to affect the ability to concentrate.
Apart from that, CO is an important indicator for the
2
presence of other hazardous substances (VOCs, solvents,
formaldehyde, radon, fine dust particles, etc.) that can be
detrimental to your health. In other words, a CO concen-
2
tration below certain threshold values usually guarantees a
good indoor air quality overall.
The table below shows threshold values for CO2
concentration that are used in practice.
Desired CO -concentrations indoor climate:
2
Nominal : 1200 ppm CO2
80% satisfied : 1000 ppm CO2
People with respiratory
problems : 800 ppm CO2
The ClimaRad Sensotronic features a CO sensor that
2
measures the CO level and automatically adjusts the fan
2
speed to maintain the desired level. Thus the ClimaRad
always provides the adequate ventilation.
Humidity and ClimaRad
Every day several litres of condense and humidity are
released in a house because of the presence of people and
certain activities like cooking, washing and cleaning. Apart
from that, in new homes, humidity may stem from the
building construction.
Mites, fungi and rot thrive on a high humidity level in the
house. The mites and fungi can cause allergies and wood
rot can be detrimental to the building construction.
Adequate ventilation can prevent high humidity. The
ClimaRad has a humidity sensor that will react to high
humidity levels and try to lower it in an intelligent way. For
instance, if in (rare) cases the absolute outdoor humidity is
higher, no extra ventilation will occur.
Outside Air and ClimaRad
Depending on where you live, outdoor air may be polluted
with allergenics (pollen), exhaust fumes (benzene), lead
and fine dust particles. Obviously these substances are not
desired indoors.
There are two types of filters available for the intake-duct
of a ClimaRad to remove these substances:
!A fine dust and pollen filter and
!a combi-filter for fine dust with an additional active coal
filter
Energy Use and ClimaRad
By far the most popular way of ventilation is opening
windows and ventilation-grids.
A considerable drawback of this “method” is that it is
unpredictable whether the ventilation is too little,
unnecessary or just enough. On top of that, the warm
indoor air is lost before its heat content (energy) being put
to good use. This energy waste is not only bad for your
wallet, but also for the environment.
ClimaRad has an air-to-air heat exchanger that transfers
the heat of the outgoing air to the ingoing cold air. This
saves a bundle on your heating costs, but also the
ClimaRad is especially equipped to perform its function with
a minimum consumption of electricity. It uses DC fans in
combination with a highly efficient power supply. At a
ventilation rate of 40 m³ per hour the electricity
consumption is as low as 7 W. At 80 m³/h it is a mere 25
W. The stand-by power use (fans-off but sensors still
working) is as low as 1.5W.
