Refrigeration dryer DRYBERG®️ RF90/AC equals to DRYPOINT®️ RA5400/AC
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 refrigeration compressor, in partial load conditions then only a small portion of the nominal refrigerant flows through a by-pass calibrated orifice of the solenoid valve 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).

Refrigeration dryers with Energy Saving Impulse Technology and Thermal Mass
With the introduction of RF, the new generation of energy-saving refrigeration dryers, BERG not only renews its product offering for the compressed air treatment but also reinterprets the concept of thermal storage operation, that made the international success of the RF dryers. The new Impulse Technology offers important advantages in terms of energy saving, reliability and operating costs as the RF dryer is able to adapt itself to the real needs of the compressed air system. The regulation system of the dryer controls the dryer operation granting the most energetically effective method of compressed air drying, achieving high energy saving and ensuring at the same time an excellent dew point stability also in dynamic conditions.
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 refrigeration compressor, in partial load conditions then only a small portion of the nominal refrigerant flows through a by-pass calibrated orifice of the solenoid valve 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.
• 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.

Function description
Operating principle – All dryer models described in this manual function according to the same principle. The hot and moisture-loaded air is led into an air/air heat exchanger. Afterwards, the air flows through an evaporator, which is also known as an air/refrigerant heat exchanger. The air temperature is reduced to approximately 2°C, so that water vapour condenses to liquid. The continuously accumulating condensate is collected in the separator to be discharged via the condensate drain. Subsequently, the cold and dry air is led through the air/air heat exchanger, so that it is reheated to up to 8°C below the inlet temperature when leaving the dryer.
Refrigeration cycle – The refrigerant is conducted through the compressor and reaches a condenser under high pressure. There, cooling-down takes place, making the refrigerant condense to a liquid state which is under high pressure. The liquid is pressed through a capillary tube where the resulting pressure drop ensures that the refrigerant evaporates at a defined temperature. The liquid refrigerant which is under low pressure is led into the heat exchanger, where it expands. The cold resulting from the expansion serves to cool down the compressed air in the heat exchanger. During this process, the refrigerant evaporates. The low-pressure gas is resupplied to the compressor, where it is compressed again. It then re-enters the cycle. In phases of a reduced compressed-air load, the excess refrigerant is resupplied automatically to the compressor via the hot gas bypass valve.

Ambient conditions!
In the event that the dryer is not installed under suitable ambient conditions, the ability of the device to condense refrigerant gas is impaired. This can result in a higher load of the refrigerating compressor, and in a loss of efficiency and performance of the dryer.
This in turn leads to overheated condenser fan motors, to malfunction of electric components and to a breakdown of the dryer. Failures of this type will affect warranty considerations.
Do not install the dryer in an environment in which chemicals with a corrosive effect, explosive gases, toxic gases, evaporation heat, high ambient temperatures or extreme dust and dirt can be found.

Air-air heat exchanger
Hot and humid air enters the air-to-air heat exchanger, where it exchanges heat in the total counterflow with the existing cold air. Pre-cooling saves energy by reducing the heat load to the evaporator area. The cold, dry compressed air flows through the secondary side of the air-to-air heat exchanger, where it is reheated by the hot supply air that pre-cools it.

Aluminium heat exchanger
The heat exchanger module consists of an air/air heat exchanger, an air/refrigerant heat exchanger, and of a high-performance separator. The compressed air flows top-down through the heat exchanger. The large cross-sections of the flow passages cause low flow rates and low compressed-air losses. In the air/air heat exchanger, the heat exchange is effected in a reverse current. This guarantees maximum heat transfer. The heat transfer in the air/refrigerant heat exchanger also takes place in a reverse current. This allows full evaporation of the refrigerant. The high-performance separator ensures almost complete separation of the condensate. Maintenance of the high-performance separator is not required.

Function of Refrigeration air dryers
A refrigeration air dryer is a device that removes moisture from compressed air by cooling it down and then condensing the moisture into liquid water. The compressed air enters the dryer at high pressure and temperature, and it is then cooled using a refrigeration system. As the air cools, the moisture in the air condenses, and the resulting liquid water is collected and drained from the system. The cooled and dried air is then reheated to an appropriate temperature for use in industrial applications. This process ensures that the compressed air is free from moisture, making it suitable for use in various industrial processes and equipment.
Certified skilled personnel

Operating principle of DRYPOINT® RA
In the DRYPOINT® RA refrigeration dryers, the air is dried in a counter-flow process with optimised heat exchange along the entire process path. The air flows in a constant downwards direction with no diversions.
The generously dimensioned counter-flow heat exchanger unit which consists of an air-air and an air-refrigerant heat exchanger, among others, cools the compressed air to a temperature of around 3°C . Therefore the size and design of the heat exchangers promote effective cooling while minimising flow resistance.
Warm compressed air saturated with moisture is pre-cooled in the air-air heat exchanger when it enters the refrigeration dryer (1). Consequently, the refrigerating capacity of the refrigerant needed in the downstream air-refrigerant heat exchanger (2) is reduced. This makes the system more energy-efficient. Gravity supports a very high droplet separation of nearly 99 %. The flow velocity is greatly reduced in the very large condensate collection chamber with subsequent broad return. This reliably avoids any entrainment of droplets which have already been separated (3).
The condensate which is produced is drained from the DRYPOINT® RA through the level-controlled condensate drain BEKOMAT®. This prevents any pressurised air losses and can be treated reliably with processing systems such as the oil-water separation system ÖWAMAT® or the emulsion splitting plant BEKOSPLIT® (4). Before leaving the DRYPOINT® RA, the dried, cold compressed air is re-heated in the air-air heat exchanger. This significantly lowers the relative humidity and recovers BEKOMAT® up to 60% of the refrigerating capacity used (1).
