A new era in drying technology

Korpikorpi’s Korvent dryer marks a new era in drying technology – and makes the process of drying damp structures significantly quicker, quieter, and easier.

Drying damp buildings can normally be something of a nerve-racking experience. People do not like being exiled from their homes, and businesses do not take easily to losing customers due to the temporary loss of space they have to put up with as a result of the slow drying achieved by conventional systems.

A quick and effective drying system has been on many people’s wish-list for a long time.

Better performance all around

Korpikorpi’s Korvent dryer is capable of drying surfaces such as concrete or brick up to four times faster than the absorption method normally used. In the case of concrete for example, Korvent can dry a damp area in less than a week in some cases, and even the most difficult cases can be handled in two weeks on average.

The benefits of getting premises back in use in such a short time are obvious – whether you are talking about a family, a business, or a construction site.

Speed is not the only advantage of the Korvent, however. With its double aluminium construction and controlled internal airflow, the Korvent is both cost-effective and environmentally friendly, using only 500 W of electricity per square metre per hour.

This makes the Korvent significantly cheaper to operate than conventional systems. A Korvent, for example, uses only 200-250 KWh of electricity to dry a few square metres of damp-affected area in a bathroom, while a conventional unit can easily use three times that amount.

Noise levels are also very low, at 45 decibels, or the equivalent of a quiet dishwasher. Conventional dryers, in contrast, normally generate 65-70 decibels of noise. This makes living or working close to an area being dried by a Korvent very feasible.

And being made almost entirely of aluminium, the compact Korvent, weighing between less than 10 kg and no more than 16 kg, depending on the model, can be moved from place and place very easily, and takes up little storage space.

After three years of design work and numerous prototypes, the Korvent is now ready to enter production.

Optimised performance

Highly optimised air circulation is a major factor in the excellent performance of the Korvent, enabling the unit to operate at an optimal temperature regardless of local conditions and minimise the volume of exhaust air generated. In practice, heating can be sustained at 90 °C for extended periods.

Thanks to well-designed thermal insulation and efficient internal air flows, a Korvent will not increase the overall ambient temperature around the unit, or suffer from excessively hot surfaces.

By combining units, which are available in four different sizes, users can easily treat walls, floors, and ceilings.

All the unit’s functions are easily controlled, even remotely, cutting the need for contractors to be on-site to a minimum. And if anything goes wrong, operators are alerted to the problem via an SMS message on their mobile phone.
