IntrCooll: dual-stage adiabatic cooling for industrial facilities.

A healthy indoor climate is essential for the well-being of your employees. In summer, IntrCooll uses 100% fresh outside air during free cooling and cooling. By ventilating the contents of the production hall several times an hour, you’re always assured of optimal air quality. The number of air changes in the colder periods depends on the amount of internal heat available. When the system is equipped with the optional Heat Reclaim module, the number of air changes is maximized.

You may not always realise it, but outside air is not always clean either. ‘Fresh’ air can be polluted by, for example, pollen, (fine) dust, exhaust gases, bacteria and mold spores. IntrCooll always purifies incoming fresh air before it is blown into the production area. In colder periods we can also guarantee a dust-free indoor climate, by filtering the air recirculated with the Heat Reclaim module. The degree of filtering depends on the chosen filter class.

Internal heat generated from machines, processes, heating, lighting and people rises up towards the ceiling by convection. IntrCooll's optional Heat Reclaim module reuses this residual heat. IntrCooll will keep temperatures in your hall consistent, it will supply preheated ventilation air and guarantees a draft-free blow-in. Horizontal temperature layers in your production area are breached (anti-stratification) and the difference in temperature of the roof (between inside and outside) is minimized. This results in less heat loss and therefore provides significant savings.

If there’s no (air) heating system present and internal heat released from machines is insufficient, the Heat Reclaim module can be equipped with heating batteries. This will heat recirculation air gathered at the ceiling. A pleasant working temperature is established. The module can be combined with all common heating methods such as gas, electric or heat pump. The control of the heating system is prepared as standard, to prevent unnecessary heating.

Even in the spring, winter or fall, cooling of your plant may be required. Despite lower outside temperatures, the indoor temperature can get uncomfortably high. This internal heat is caused by machines, processes and sunlight from windows and skylights. In contrast to traditional cooling systems such as air conditioning, where air is mainly recycled, we use outdoor air smartly with free cooling. This allows us to cool and ventilate your workshop "free of charge".

When the outside temperature increases further, the system switches to dual-stage adiabatic cooling. The first indirect adiabatic "cooling step" uses cold recirculation water to pre-cool the ambient air. Because no moisture is added, the air has a lower dry bulb and wet bulb temperature than the outside air, when leaving the heat exchanger. The second direct adiabatic "cooling step" cools the air even further through Oxycom's patented Oxyvap. The combined wet bulb efficiency increases to 114%.
