In buildings and premises where we stay regularly and for longer periods of time, we should settle high demands on the air quality!

Ventilating office buildings a certain proportion of outdoor air is used. This means that moisture is introduced into the building during parts of the year via the ventilation. Humidity and temperature should be kept relatively constant at a level preferably below 55% RH to avoid corrosion and mold growth. Moisture affects the entire building, from the building elements themselves to those in the building and their health! Materials and equipment stored or used on the premises can also be damaged by too high a moisture level with corrosion or mold formation.

Airwatergreen energy efficient dehumidifiers are installed in a large number of properties in attics, basements, crawl spaces and in archives – above and below ground. Being able to dehumidify just as efficiently at low temperatures they are very appreciated, as it has made it possible to reduce heating costs in rooms that are rarely used. Being able to install the dehumidifiers without unnecessary drawing of ventilation pipes has reduced installation cost and made installations possible that were not financially viable to address before.

Below ground

Challenges

The moisture load in premises below ground comes in through floors and walls. If the moisture level is too high, mould and bacterial growth soon develop in the creep ground. Mould is then spread to the rest of the building, resulting in reduced air quality.

Our solution

FLEX can be set to be controlled against “mould index” (LIM1) which provides optimum control to the right moisture level depending on the temperature in the crawl space. The installation is simplified by the fact that we generate dry air in place and that the dry air is distributed in the space of the powerful built-in fan.

BASEMENT STORAGE

Challenges

Moisture in basements can either come from the ground but also from poorly drained walls. The risk of high humidity levels in the basement spaces is both corrosion and mould in the space and that the moisture level is too high in the concrete. If the concrete is too moist, the reinforcement can begin to corrode, which can lead to the concrete being blasted.

Our solution

FLEX & REX is suitably set against a relative humidity level below 60% RH to protect against corrosion and mould. The installation is simplified by the fact that we generate dry air in place and that the dry air is distributed in the space of the powerful built-in fan. This makes it easy to install the dehumidifiers in existing buildings

PRODUCT CHOICES

The product selection depends on the moisture load that can be estimated by calculation. In smaller to medium-sized spaces, FLEX is the natural choice. Dew point sensors can be used to control the FLEX against the correct moisture level to avoid condensation on cold surfaces. Alternatively, the expected moisture level is set so that the dehumidifier controls that level.
FLEX Can be mounted on wall bracket or stand freely on the floor.
Both FLEX and REX can be connected to existing monitoring systems via Modbus.
