Compressed Air Dryers

Cooling is the simplest and most positive way of removing moisture from compressed Air. A Refrigerated Dryer has closed-loop Freon circuit, which cools compressed air to a controlled temperature and so condensed moisture is separated out. To prevent freezing of condensed moisture in the heat exchanger, Air/Gas, can be cooled to a minimum temperature of +2-3°C approx i.e.

Compressed Air Dryers:

• Moisture Use Air / Gas Dryer
• Water or Moisture in the compressed air system causes air leakages, damages tools systems and ultimately increases cost.

Problems due to unwanted moisture in the compressed air system:

• Rust and scale deposit in steel pipes causes leakages, increase resistance to flow.
• Malfunctioning of pressure control equipment & instrumentation.
• Corrosion in Solenoid valves & Pneumatic cylinders.
• Solidification of media in pneumatic conveying systems.
• Bubbling or orange peal effect in paint spraying & powder coating.
• Sluggish operation of cylinder, valves & other moving parts.
• This results in loss of efficiency & material and increases downtime. Moisture is usually the single major cause of unnecessary costs to compressed air system. The cost of drying air is much lower than the damage. Thus clean, dry compressed air produced using air Dryer is essential.

Technical Specifications:

Modern industry's increasing levels of sophistication and capital investment imply that highest precision with zero downtime is an absolute must for an economically viable process. Integrated Engineers & Contractors cooling solutions, developed specifically for industrial users, perfectly answer industry's need for precise temperature control and absolute reliability, 24 hours a day, 365 days a year. The cost of not implementing the optimized solution far exceed the cost of an optimized Integrated Engineers & Contractors industrial cooling solution. 

Heatless type Dryer takes advantage of the natural phenomenon of desiccant to establish equilibrium with their surroundings. In this type, wet Air (fluid) is cycled automatically between two desiccant towers, one adsorbing the moisture from the wet fluid, while the other being regenerated. The wet fluid enters one tower, passes through the desiccant bed where the saturated moisture is adsorbed. A small portion of the dried air at ambient temperature and pressure is passed through the desiccant bed in the second tower for regeneration and is purged to atmosphere. At preset interval, the towers changeover automatically and the cycle continues giving out a regular supply of super dry Air having dew points up to (-) 70°C to (-) 80°C (At atm. pressure)

Dew point is the measure of moisture content in air. It is the temperature at which moisture content present in the air, starts condensing. Lower the dew point, more dry is the air”. Air of (-) 40°C Dew Point means no moisture would condense unless temperature of the compressed air is reduced less than (-) 40°C. Lower the Dew Point, higher would be the operating cost of Air Dryer. Hence proper selection of Dew point is very important for economical operation of the unit.

• Dew Point up to (-) 80°C can be achieved.
• Soft Seated imported control valves used for bubble tight shut down.
• Gradual depressurisation and repressurisation prevents bed attrition.
• Epoxy coated towers from inside.
• Stainless steel desiccant support screen inside tower.
• Low-pressure drop of 2 Psig only.
• Fabricated as per ASME sec. VIII, Div-1 or IS 2825 codes.
• Units fully tested before despatch.
• Stage-Wise inspection involved.
• Modular skid mounted units.
• Quality product, only quality components used.
• Economical.
