Compact, heatless compressed air dryers for volume flows up to 86m³/h and dew points of -25°C to -70°C.
The Parker Zander K-MT 1-8 range of heatless adsorption dryers are designed to dry industrial compressed air reliably and efficiently down to a pressure dew point of -70°C. The units are compact and can be installed either free-standing or wall mounted. They come equipped with integrated high performance pre- and after filtration and are capable of volume flows up to 86 m³/h in a system operating at 7 barg (100 psig).
Features
• Pressure dew point down to -70°C stable
• Volume flows up to 86 m³/h @ 7 barg (100 psig)
• High performance pre- and after filters installed as standard
• Energy saving dew point dependent switching (DDS) as an option
Benefits
• Highest quality air
• Compact and space saving
• Energy efficient
• Very flexible due to a wide range of options and accessories
Operation
Compressed air first enters the GL pre-filter. Next, the air flows into one of two adsorption chambers both filled with molecular sieve – a renowned drying-agent, where the compressed air is dried. During the drying cycle, the second chamber undergoes regeneration. At the start of the cycle, this chamber exhausts to atmosphere, and a small portion of dried compressed air passes through the adsorption bed, transporting the humidity out. When the regeneration process is complete, the regenerated chamber is re-pressurised in readiness to repeat the drying process. Continuous, uninterrupted operation is maintained utilizing so called pressure-swing technology together with individually operated main- and exhaust valves.
Dry compressed air finally exits via a GL after-filter preventing the migration of particles into the downstream compressed air network. K-MT 1-8 adsorption dryers operate a fixed, timed, changeover cycle between the two drying chambers.
Energy Savings
Where an application calls for a unit able to cope with variations in operating pressure and load, the installation of a dew point sensor at the outlet of the dryer is available as an option. In such an operating mode, the changeover cycle between chambers only takes place when required, and is dependent on the required dew point being achieved. Only upon reaching this adjustable set dew point, does changeover to the regenerated chamber occur. This feature enables the drying phase to be lengthened and thus avoids the unnecessary use of purge air for regeneration and consequently provides energy savings.
Compressed air can be selectively dried to meet a dew point of -25°C down to -70°C.
