Desiccant Dryers

Compressed Air Systems should be designed for just the right quality of air at the most economical costs. Delair has a wide range of dryers for all your needs, for general plant and instrumentation air.

If the application requires extra dry air and PDP below -20°C, the delair has a large range of adsorption dryers for the job-heatless regenerated and energy-less.

Desiccant Dryers, heatless type, use 10 to 15% purge air for regeneration of desiccant i.e. 10 to 15% of compressor power (HP) is being used as energy operating costs for drying thereby increasing the capital costs in installing extra capacity of the compressor. They contain two pressure vessels or towers, each containing a quantity of desiccant. One tower dries the air, while the other is being reactivated.

The ‘heatless’ principle of regeneration is based on the physical property of the desiccant, given as Delsorb as one of its kind in Asia and approved by all major consultants, which liberates the adsorbed water vapour, if air with a low water vapour pressure is passed through it.
