MODEL SELECTION

What We Need to Select the Right Model

The unit capacity is determined by the amount of water evaporating from the pool. The information listed here is enough to calculate it. You can make a preliminary selection in a few minutes with our sizing tool, or send us the information and we will make the selection together.

Smart Features

You'll know before you even check.

MicroLight+

MicroLight+ Humidity Indicator

Microwell microLIGHT+ is a unique LED technology designed to quickly and accurately transform the current level of humidity into colour. Green light, just like on traffic lights, means that everything is ok. Red light alerts high humidity. Blue light simply tells you that humidity is too low — so you can turn your dehumidifier off and save on electricity.

Green — Humidity is ideal — environment is healthy (55–65%)

Red — Humidity is high — unit is actively dehumidifying

Blue — Humidity is low — ventilation recommended

Options

Configured to Your Needs

In its standard form DRY WAVE meets the needs of most pool halls. Depending on the conditions of the hall, the options below can be added at the ordering stage.

Control options

In addition to the digital panel on the unit, the wireless EASY 300 controller or a wired room controller can be selected. Placing the controller on the opposite wall of the pool hall ensures that humidity is measured and controlled evenly across the whole hall.

Additional air heater

If the heating in the hall is insufficient or a backup heat source is wanted, an additional heater can be added to the unit. The electric heater is rated 2–2.5 kW and switches on automatically according to the panel setting. The hot water heater is fed from the building heating system; its output is 1–7 kW depending on the model and water temperature, and it can be supplied with a solenoid valve.

Air filter

Pool halls are generally dust-free and most applications do not need a filter. When selected, the filter also captures chlorine and salt particles along with dust, helping both the unit life and the cleanliness of the room. It sits on the inside of the cover and cleaning it every two to three months is enough.

Fresh air connection

The unit can be equipped with a Ø100 mm connection to take in fresh air from outside. In this case there must be an exhaust fan on the opposite side of the hall working together with the dehumidifier; the fan can also be powered and controlled from the unit itself.
