Vaps Copsair Heatless Dryer

Heatless

The Modular VAPS Copsair Heatless Pressure Swing Dryer for Compressed Air Dryer offers the lowest capital cost and lower long term operating costs compared to conventional heatless dryer. The VAPS Copsair Heatless dryers offer the highest

reliability solutions for low dew point compressed air.

These dryers are made simple to install, operate and able to provide consistent low pressure dew point of up to -40°C and -70°C

How the VAPS Copsair Heatless Dryer work
Saturated compressed air enters the system through the Pre- Filter, where liquid water and oil contaminants are removed. The air then enters the dryer through the right chamber.

Moisture is adsorbed by the desiccant as the air flows through the chamber. Adsorption is an exothermic (heat releasing) process, and as it progresses through the chamber, heat of adsorption is released. This heat later contributes to regeneration. Dry compressed air exits at the outlet valve, and then through an After Filter, where any desiccant dust being carried by the air will be removed. The clean and dry air then
proceeds downstream to the plant.

While the right chamber is in the drying cycle, the off stream left chamber is depressurized to atmosphere. A portion of the -40°C/-70°C PDP dry air is metered through the purge adjusting valve, expanded to atmospheric pressure further reducing the actual dew point making the regeneration air more dry, and this then passed through the wet desiccant bed counter-current to the drying flow. This extremely dry regeneration air, in conjunction with the heat of adsorption stored in the bed during the drying cycle, regenerates the desiccant bed. The regeneration air is then exhausted through the exhaust valve and a silencer to the atmosphere. Prior to switching, the newly regenerated left chamber is re-pressurized by closing the regeneration outlet valve

The dryer operates on a 4 to 10 minute automatic cycle, depending on the settings
Example : 5 minutes drying and 5 minutes regenerating.

ADVANTAGES

Lower Energy Consumption
Better Safety – No Hot surfaces
Easier and Faster Maintenance
No Need to Heat and Cool Down Desiccant
Longer Desiccant Life with lower dusting
Very Reliable and Uncomplicated Operations
Less Moving Parts and thus less chances for breakdowns
Lower Capital Investment

Dual–Core Construction

Exclusive Dual-Core design contribute to even and equal flow pass through each desiccant tube and desiccant bed, Avoid desiccant dusting and Channeling-Effect which likely happen in other traditional desiccant dryer ,those will cause lousy performance on Pressure Dew Point, Furthermore dust and wet air definitely will lead to the severe damage to air equipment. Dual-Core Modular design solve these problems and maintain a constant performance on PDP -40°C /-40°F

Dual-Core desiccant tubes are perfectly secured with bottom and top manifold and the sophisticated construction design can help the flow pass with minimum resistance, It all lead to minimum pressure drop and minimum purge lost compare to traditional desiccant dryer.

Independent In–Core desiccant tube
Removable In–Core tubes can be replaced directly on site with Copsair original filled brand–new In–Core desiccant tube, It make sure the PDP performance is absolutely same with new dryer

Double Guaranty Of Anti-Leakage
Leakage is always the potential risk for traditional modular dryer due to compact and manifold construction ,Dual–Core design can give double warranty to prevent leakage ,Dual–seal ,Dual–Pressure–Hold, Dual–Anti–Leakage, It contribute to more energy saving and stability.
