do you have questions?

LETS compressed air systems are equipped with a refrigeration dryer. Without extra compressed air drying, malfunctions, production stops and costly maintenance and repair works are inevitable. Other options are an adsorption dryer or a membrane dryer.

Why choose a LETS bv compressed air dryer:

  • High-quality compressed air
  • For an operationally reliable compressed air system
  • Save on maintenance and repair works

How it works

The atmospheric air that is sucked into the compressor is a mixture of gases that also includes water vapour. When the temperature rises, such as during compression, the potential for water absorption also increases. Because the air cools down afterwards, large quantities of condensate are formed in the air pipe network and around the eventual air users. This is undesirable.

How much can you save on your energy costs?

Compressors consume 5-20 times the purchase price in power costs. Therefore, LETS compressors are standard frequency control, driven directly and have a low speed, which leads to considerable savings. Possibly expandable with heat recovery.

How it works

Refrigeration dryer
With a refrigeration dryer, the temperature of the compressed air is brought down, causing the water vapour to condense, and then we dry the compressed air. The temperature reached is 3°C, called the pressure dew point. The compressed air is not able to absorb more than 5.95 grams of water vapour, so the compressed air is dry and suitable for use as long as the compressed air does not come into contact with temperatures below the pressure dew point.

Membrane dryer
Membrane dryers require no electricity and are almost maintenance-free. They also only condition the compressed air when there is demand, and do so at the required quality. Membrane dryers can be used flexibly for various dew point requirements. The desired dew point at the membrane dryer’s exit can be adjusted to the user’s desires.

Adsorption dryer
When compressed air with a pressure dew point of 3°C comes into contact with temperatures below 3°C, condensation will form again and using a refrigeration dryer is no longer sufficient. For those applications, we use adsorption dryers. Applications of adsorption dryers are for instance necessary at points where the compressed air pipes are outside, or inside of cooling cells, and for certain processes where very dry air is a necessity.
