Refrigerant Dryers

This revolutionary design matches energy consumption to the work load to achieve energy savings while in operation.

Advanced design makes this dryer extremely compact and lightweight. Small footprint and frontal access for all controls and refrigeration components save valuable plant floor space.

DE iTECH automatically adapts itself to any operating condition, without any need to adjust or switch OFF the dryer. User friendly digital control is standard on all the models and shows all the main parameters, providing warnings and alarms to ensure correct dryer operation.

Thanks to some sensors placed on the refrigeration and on the compressed air circuits, the microprocessor controls the dryer operation granting the most energetically effective method of compressed air drying.

• For high/medium flows, the dryer applies the Impulse Technology to regulate its drying capacity.
• For low air flows, the dryer utilizes the thermal storage operation.

IMPULSE TECHNOLOGY FOR HIGH/MEDIUM AIR FLOWS
The refrigerant compressor is permanently ON to achieve a perfect control of the dew point.
The microprocessor controls through “impulses” the opening and closing of a solenoid valve installed on the suction pipe of the refrigerant compressor, in partial load conditions then only a small portion of the nominal refrigerant flows through a by-pass capillary to the compressor.
In partial load conditions the compressor compresses less refrigerant than at peak load and therefore it consumes less energy (refrigerant flow control technology).

THERMAL STORAGE OPERATION FOR LOW AIR FLOWS
The refrigerant compressor cycles ON/OFF for maximum savings and reliability.
Since the refrigeration capacity is greater than the load, the excess capacity cools the all-in-one exchanger that acts like a thermal storage.

New 3-in-1 high efficiency heat exchanger with optimized fluid dynamics useful to keep the pressure drops to a minimum level.
Advanced drying capacity control by impulses or by thermal storage effect.
Enhanced energy savings (up to 80% compared with hot gas by-pass dryers).

The stainless steel demister separator efficiently removes the condensed moisture at all airflows (unlike centrifugal separators). This ensures a high grade of drying all the time.

High maximum inlet temperature +70 °C (DEiT 018-080) +60 °C (DEiT 100-270) and maximum ambient temperature (+50 °C) ensure a fail – safe operation at all times. High maximum operating pressure (16 barg).

Hybrid drying technology by combining two drying processes into a single dryer, direct exchange and thermal storage operation; the result is the very lowest energy consumptions. This concept also offers the most reliable dryer technology, ensuring continuous operation in all conditions. Ease of use is assured: DE Hybrid switches itself off when not needed and requires absolutely no seasonal adjustments. All models feature advanced digital controls and the unique iDRAIN condensate drain.

DE Hybrid: 2 dryers in 1, much more than twice the benefits.

The GTS exchanger’s cycling function and unique Hybrid operation save up to 80% of your energy. Choose between 2 dew point settings, permitting further savings when conditions permit it. The iDRAIN condensate drain notably reduces unwanted energy losses.

The simple refrigeration circuit, without a hot gas valve, notably increases reliability. The compressor runs cooler and less often, increasing its longevity. Extensive factory testing offers peace of mind, and wide air paths reduce the chance of air-side blockages.

DE Hybrid requires no start-up programming, automatically adapting itself to any operating conditions. On-off operation means there is never a need to switch the dryer off. Digital controls, standard on all models, offer a User friendly interface.

There is no need for seasonal adjustments, unlike dryers with hot gas valves or traditional drains. The simple refrigeration circuit is easy to maintain, whilst the top mounted condenser reduces fouling. The controller features a user programmable service warning.

DE Hybrid operates up to class leading air inlet (70°C) and ambient (50°C) temperatures, and pressures of 16barg (50barg also available). Refrigerant R134a offers high overload capacities. There is no hot gas valve so the risk of freezing in winter is avoided.
