Humidity management

WHAT EXACTLY IS HUMIDITY

HUMIDITY IS THE AMOUNT OF MOISTURE PRESENT IN THE AIR

Humidity is the amount of moisture present in the air. Absolute humidity is the amount of moisture present in a particular volume of air, and is normally measured in grams/m3Relative humidity, on the other hand, is the relationship between the actual amount of moisture present and the maximum amount that the air could contain. Relative humidity is always measured in percentages.

Inappropriate levels of relative humidity give rise to a wide range of potential problems in industrial processes and commercial operations of virtually all kinds.Uncertainty and lack of control are never a good thing in business – so Cotes humidity management capabilities are designed to help you establish full control over humidity conditions in important structures, equipment and processes.

 

Relative humidity and the dew point

This film explains the relation between relative humidity and the dew point, and how you can manage this to get the results that suit you best.

HUMIDITY PROBLEMS

The most common problems stemming from airborne moisture and undesireable humidity include:

CONDENSATION

Condensation arises when air – which almost always contains certain amounts of moisture – has a different temperature than the surfaces it comes into contact

CORROSION

Any combination of airborne moisture and oxygen is a fertile basis for metal corrosion. Iron and steel rust and lose structural integrity, while copper

MOULD, FUNGI AND BACTERIAL GROWTH

Mould, fungi and bacterial growths of all kinds occur easily in environments where the relative humidity is high – the humidity helps give them the

ICE FORMATION

When there’s lot of moisture in the air and you have no control over it, it’s really a problem waiting to find somewhere to manifest itself.

ELECTRICAL FAULTS

Moisture and electricity are never a good combination. High levels of moisture in the air - humidity - can often result in faults and operating glitches

CLUMPING AND BLOCKAGES

Uncontrolled humidity often has significant effects on powders and granulates of all kinds – they have an exceptionally large surface area in contact with

SEASONAL FLUCTUATIONS IN AIR CONDITIONS

In most parts of the world, ambient air conditions fluctuate significantly from one season to another. Climate change is also resulting in increased uncertainty

COTES TECHNOLOGY

Cotes is the world’s leading expert in adsorption dehumidification technology, providing superbly engineered, low-maintenance humidity management solutions that are remarkably energy efficient.

A Cotes adsorption dehumidifier is a sleekly designed, fully enclosed unit that includes a rotor, geared motor, ventilator fan(s), heater, air filters and an integrated electrical control system.

We can also add other equipment and special heating/cooling capabilities to tackle your specific requirements and priorities. The best technology and the best know-how about how to apply it effectively are a potent combination.

 

The adsorption dehumidification principle

The effect of Cotes adsorption dehumidifiers basically stems from the action of two flows of air. The process is self-sustaining and requires little maintenance.

HOW IT WORKS

This film explains how the two air flows are used to collect and lead away airborne moisture.

HOW YOU BENEFIT

Effective humidity management gives you a degree of control over operating conditions that is often crucial for future profitability.

Dehumidification technology is the most cost-effective and environmentally responsible way to tackle many practical problems widespread throughout industry. It’s a relatively straightforward, inexpensive way to implement pro-active measures that help you maintain the value of key structures and other high-value assets, reduce energy consumption, and boost the efficiency of a wide range of industrial processes.

Better control over the moisture in the air gives you:

  • Better control of key parameters that affect your raw materials, production processes, manufacturing installations and fixed assets
  • A way to actively prevent detrimental conditions and events that include condensation, rust and corrosion, mould and rot, electrical faults and spoilt materials
  • Longer service life and better return on investment for structures, buildings and equipment
  • Reduced expenditure on service, maintenance and refurbishment
  • Lower energy costs and reduced environmental impact
