"Yes, we have installed a good air dryer but some moisture is there."

We, at Adsorbtech, reject this statement. We bring to you a new standard in compressed air treatment:

Introducing The Adsorbtech CAT Unit

3% Purge loss only

Year round performance

100% Result oriented

The Compressed Air Treatment ‘CAT’ Unit is a twin-tower, desiccant based air drying system with multi-stage filtration

that eliminates moisture, oil, dust and bacteria in a step-by-step process to deliver bone-dry air at the point of your compressed air application. 

Based on adsorption technology, the CAT employs a specialized desiccant to adsorb water molecules from the compressed air, 

thus generating bone-dry compressed air.

Adsorbtech CAT Unit is designed to treat incoming compressed air of temperature 100ºC

Based on the heated purge principle, the Adsorbtech CAT has purge loss of only 3%. 

Adsorbtech audits your requirement, and designs, manufactures and installs a tailor-made CAT Unit just for you.

No additional filters or dryers are required once CAT is installed, to get dry compressed air at usage point.

Frequently Asked Question

Rising maintenance costs, expensive and unnecessary spares, production downtime and long-term capital expense are common issues.
If the compressed air comes in contact with the product (process air), untreated air can contaminate it, leading to increasing rejection costs and thereby increasing costs for solutions also.
Pipelines carrying the untreated compressed air also contribute to increased costs due to scale formation and shortened life.

Capital: The air compressor comprises the major cost.
Oil-free compressors are substantially more expensive than oil lubricated compressors.

Power: Power usage is the highest cost in the lifetime of a compressed air system. An efficient compressed air system will ensure high utility of the compressor. A key factor in controlling power expense is the purge loss factor of the system.
For example, if a compressed air system generates 100 CFM of compressed air and has 12% purge loss, that means the user only gets 88 CFM air at the outlet of the system for actual use.

Maintenance: Here, maintenance is not just of the air system but also of the pneumatic equipment, product, pipeline that are associated with the compressed air. If the air is wet and improperly treated, all related maintenance costs will go up.

Breakdown: Similar to maintenance, the breakdown cost is tied with the equipment/product/pipeline. A breakdown in the air system could lead to production downtime, spoilage of product and failure of pneumatic equipment.

Your air compressor will work best when kept in a clean and cool environment. The more pollutants in the surroundings, the faster your compressor health declines.

Purge air is clean and dry compressed air that is used to regenerate the CAT Unit. Compared to industry standards (15-25%), the CAT requires only 2-3% of purge air.
