Compressed Air Powered Pneumatic Systems

April 29, 2011


Delair is leader in compressed air treatment. All pneumatic systems are run through compressed air. These compressed air dryers are energy-efficient. Compressed air pneumatic systems are used widely throughout industry. Almost every industrial plant , from a small machine shop to an immense pulp and paper mill , has some type of Pneumatic compressed air system. In many cases, the pneumatic compressed air system can vary in size from a small unit of 5 horse power to huge systems with more than 50000 hp.

Compressed Air dryers are absolute essential for pneumatic systems / tools / valves. Pneumatic systems in fixed installations in factories and manufacturing units which are powered by Compressed air Compressed air is used as a source of energy, much like electricity.. A major problem in compressed air systems is the presence of water, dust particles, oil (oils particles are introduced by lubricated air compressors) and solid contaminants which can adversely affect air quality. To out come these problems compressed air dryers are used for powering pneumatic systems.

Delair manufactures different types of dryers for pneumatic system like : Refrigeration dryer, Desiccant dryers and customized engineered air dryers. 

A desiccant dryer works on the principal of usage of a desiccant  to absorb moisture and oil found in the air supply. The benefits of desiccant dryers are their low cost and ease of installation. These types of dryers are recommended for small operations that see low or intermittent use for micro-abrasive blasting. These instrumentation air dryer can also be used for pet drying, pneumatic air drying. For painting purpose, paint booth dryers are used. Desiccant dryers are an excellent low cost solution for small scale or intermittent blasting.

Refrigeration dryer operates on the method of cooling the air to near freezing point to remove the moisture and reheating it to approximately 10°C below the incoming compressed air temperature at nominal conditions. For general plant air, dew points of 2°C to 4°C are considered adequate, well within the range of refrigeration dryers. Refrigeration type dryers use less energy and hence are lower in first and operating costs. The refrigeration type air dryer is a packaged self contained unit, fully automatic and produces a steady level of dew point. There is no regeneration cycle with complex valving, no periodic recharging of chemicals, oil in the air stream does not affect performance.

Customised / engineered adsorption dryers also works on the principal of usage of a desiccant  to absorb moisture and oil found in the air supply but it is designed and produced to the exact specification of the customer.
