why adsorption?

The goal of construction drying should always be to restore the natural moisture balance of a building.

This can be achieved when the drying air has a relative humidity (RH) that matches or is slightly below the normal moisture 
level of the space. Ideally, the drying air should be 10% below this level to maximize drying performance.

The table shows typical climate data and the corresponding recommended indoor target values. 

In winter, a relative humidity of 40% RH should be aimed for, while in summer, 45–50% RH is recommended.

The most effective and sustainable way to achieve these conditions is through adsorption drying.

How to choose the right technology?

Choosing the right dehumidification technology plays a critical role in the speed and effectiveness of the drying process. 

Our guide is based on the ANSI/IICRC S500, PAS 64:2013 and ISO 13788 standards. It will walk you through the following steps:

  1. Setting Drying Goals
  2. Defining the Room’s Humidity Setpoint
  3. Choosing the Best Dehumidification Technology

To make this process easier, we provide a humidity setpoint map that converts meteorological data into the recommended indoor climate settings, based on the ISO 13788 standard.

What our customers say

CL26_Window Kit_Water Damage_Room

"

At Polygon Denmark, we are highly impressed with Cotes' dehumidifying solution for the damage service industry. ​ ​

We prefer to dry out using adsorption dehumidification rather than condensation dehumidification, as it is generally more efficient and works at low temperatures. Additionally, it eliminates issues with condensation elsewhere in the building. ​ ​

The Cotes CL26 is a highly effective dehumidifier where innovation solves the usual problems associated with dehumidifying equipment. The dehumidifier is small and very lightweight, which improves ergonomics.

The Cotes Window Kit is a simple and time-saving way to dispose of the exhaust air. The Cotes dehumidifier is the preferred solution and thus in high demand among our technicians. We highly recommend Cotes' solution.​

CL26_Application_Bathroom

"

The Cotes CL26 adsorption dehumidifier is the best solution for building drying I have experienced in my 19 years in the industry. It is incredibly efficient – drying deeply, delivering high pressure, and offering significant airflow, undoubtedly the fastest way to dry after water damage. The adjustable EC fans and a program for either low energy consumption or high capacity depending on the need are a huge advantage.

The option to add a mold filter to the intake makes it possible to use it for cavity drying, opening up entirely new application possibilities.

Its ergonomics, low weight, and high energy efficiency align perfectly with our values of protecting employees and being a sustainable supplier. We are also very enthusiastic about Cotes’ window kit, which makes installation incredibly quick. We give our warmest recommendation to Cotes and their building drying solutions.
