Allegro 15-25 screw compressors are energy-saving devices with variable speed and direct drive. They ensure long use, long service intervals and high efficiency. The devices are available for mounting on a frame with or without a dryer and for mounting on a tank with a dryer. Allegro 15-25 compressors are offered in 4 power versions that operate in the operating pressure range from 5,5 to 13 bar. The appropriate set of optional equipment makes the Allegro 15-25 screw compressor with variable speed a complete device retrofitted with a refrigerant dryer, a pressure tank and 2 filters.
Allegro 15-25 variable speed compressors owe their high efficiency to the screw element with increased flow capacity. This solution allows you to reduce energy costs. The direct drive used in the devices translates into no transmission losses. The use of variable rotational speed allows both the adjustment of compressed air production to the needs of production processes and reduces energy demand.
A heat exchanger is also available as an option, which allows you to recover part of the energy used to compress the gas.
Allegro 15-25 variable speed compressors are characterized by low noise emission, which allows them to be installed at workstations. In this way, not only the risk of pressure drops in the network is reduced, but also the consumption of electricity necessary to maintain the appropriate pressure in the installation and the risk of leakage.
The Allegro 15-25 variable speed compressors feature an intuitive and easy-to-use Air Control 5.1 controller, which ensures proper monitoring and control of the device, as well as control of fault warnings and complete information about the service schedule. The advantage of the controller is its intuitive graphic screen.
Allegro 15-25 screw compressors use two-micron closed filters responsible for eliminating impurities at the device inlet. To increase the efficiency of the variable speed compressor, air is taken from the room from the cold side of the compressor. The durability of the oil, components and entire compressors is enhanced by separate air flow, which ensures efficient cooling of the motor and inverter.
To increase the operating efficiency of the Allegro 15-25 variable speed screw compressor, it is worth using the available options, including an internal water separator that reduces the humidity of the compressed gas by up to 90%, linear filters capturing dust particles up to 0,1 ppm or an electronic separator drain. water.
