Air Dryers

Water vapor is contained in high-pressure air. In vapor form, the water does little damage in most components. But if the water is allowed to condense in the system, it can rust pipes, freeze up actuators, and damage a process, tool, or instrument. Manufacturers of pneumatic components normally specify that air of a certain dryness be supplied for best operation. For example, some pneumatic instruments and logic elements require ultradry air; at the other end of the scale, most pneumatic hand tools require only that moisture not actually turn to liquid during the air-expansion process. Main-line pneumatic system dryers are installed close to the compressor, usually between the air receiver and distribution lines. Such a unit dries the whole pneumatic system in a plant and prevents a host of filtration problems throughout the system. Individual dryers may be used directly upstream

Products & Services
Laboratory Freeze Dryers
Laboratory freeze dryers preserve samples by freezing the material and then allowing sublimation to occur. This water-removal process is also known as lyophilization.
Sample Dryers
Sample dryers are used to remove liquids from a sample through techniques such as freeze drying, spray drying, and evaporation.
Aftercoolers
Aftercoolers are heat exchangers for cooling the discharge from a compressor.
Compressed Air Dryers
Compressed air dryers utilize technologies such as refrigeration, desiccant adsorption, and membrane filtration to remove contaminants, particularly water, from the air.
