Water processing facilities


A reliable supply of clean drinking water doesn’t happen by itself. Processing and pumping facilities are essential. Uncontrolled humidity in these facilities could lead to all manner of problems, including:

  • Condensation on pipes, tanks, building surfaces, structures, fittings and equipment
  • Undesirable microbial and bacterial growths, encouraged by humidity and condensation
  • Health and safety risks for personnel, due to pooling condensate
  • Service interruptions resulting from the need for unscheduled maintenance work
  • Energy consumption, operating and maintenance costs that are unnecessarily high
  • Difficulty maintaining mandated hygiene standards


Ensuring controlled humidity in water processing facilities

Humidity challenges in water processing facilities

For those who have to manage and run modern water processing facilities, one of the major practical challenges stems from condensation – and the many problems and costs that result from this constant plague.

When warmer, ambient air containing moisture comes into contact with cooler surfaces (such as cold pipework and storage tanks, as well as building surfaces), it often condenses – and then drips, pools and accumulates on surfaces, structures and equipment.

This in turn gives rise to an environment that’s pretty much deal for corrosion, along with conditions favourable for the growth of many types of microbes and bacteria.

Getting rid of the problem

Cotes adsorption dehumidifiers are the most effective way to deal with any condensation issues – and the resulting corrosion, mustiness, mildew and mould – in water processing setups of all types, including oxygenation, filtration and biological processing.

They enable you to carefully control the dew point of the air so that such condensation simply cannot arise, because of the basic laws of physics. This means expensive traditional – but largely ineffective – anti-condensation measures such as heating and ventilation simply aren’t needed.

Preventing condensation also enables you to maintain a controlled hygiene regimen, thus avoiding cross-contamination and compliance issues. This is often vital in conjunction with potable water installations.

Standard Cotes dehumidifier units are equally effective over the whole range of temperatures between -15°C and 35°C, and feature the only dehumidification technology that works effectively at the lower temperatures often found in water treatment plants.

Cotes adsorption dehumidifiers also have another big practical advantage compared with traditional condensation units. They’re fitted with ultra-reliable fans designed to create a slight overpressure, to distribute the dehumidified air to all the areas you specify – with no need for costly special ducting or additional ventilation setups.


  • Maintain better end-to-end control of air conditions, wherever required
  • Do away with problems caused by condensation and corrosion in and around structures, fittings and equipment
  • Ensure a reliable, uninterrupted service to your customers
  • Reduce energy consumption, operating costs and maintenance costs
  • Make it easier to achieve required hygiene standards
  • Improve health and safety conditions for staff

How Cotes stands out from the competition

  • Effective from -15°C up to 35°C
  • Only adsorption dehumidifiers available with heat recovery
  • Help you distribute controlled-humidity air throughout the facility, with no extra fittings needed
  • Comprehensive control options, for unmanned operation and maximum flexibility
