Vimodrone, July 2017 – In order to make the operation of your rotary vane compressors even more efficient, Mattei offers a new range of high-tech adsorption dryers.
Born out of Mattei experience in responding to the needs for high-quality compressed dry air in all industrial sectors, from food to biogas production, the DD range of heatless desiccant dryers use alumina-based technology. Alumina is an absorbent material that guarantees consistently high performance in delivering compressed air purity, certified in accordance with ISO8573:1 – 2010 (up to Class 1 for water).
Avaliable with flows from 5 to 1900 Nm³/hr, these new dryers represent a clear, quality solution to the problems caused by contaminated compressed air, which if introduced into production cycles when saturated with water vapour, can cause serious damage to compressed air equipment. By reducing the humidity, the Mattei dryers maintain the quality of the air supply and protect the components of the compressor from damage, expensive repairs and possible breakdowns.
The ultra-compact and lightweight design of the dryers is especially appreciated during the installation phase because they are easily installed even within existing systems that quite often have limited space, that is not suitable for traditional dryers. The dryers can be wall- or floor-mounted and the setup requires just a few simple steps. Maintenance is also made easy by the design simplicity: the specially patented combined filter and desiccant cartridges they are equipped with can be replaced in just 15 minutes.
The removal of moisture and contaminant particles, concentrated in the air compression phase, is rigorously controlled through a highly efficient PLC control system that is very accurate and reliable. All the information monitored is available on a large digital display. Another interesting energy-saving feature is the compressor synchronisation which starts and stops the dryer with a signal from the compressor, eliminating purge loss when drying is not required.
The new desiccant dryers have been designed to save energy, in line with Mattei corporate values. Their advanced design limits regeneration purge air usage to around 15%. Available as an optional extra, dew point monitoring offers energy savings of up to 60% during reduced inlet moisture loading. Through a sensor integrated into the dryer the outlet dew point is constantly monitored allowing the cycle time to be adjusted accordingly depending on the actual moisture load. The energy saving option reduces valve actuation in a functional and efficient manner, thereby increasing the service life. As a result Mattei has offered an extended 5-year warranty on the valve, if this option is chosen.
All the new Mattei desiccant dryers guarantee an uninterrupted flow of compressed air with a consistent air pressure at an optimum dew point set as standard to -40°C (-40°F). Optional dew points from -20°C (-4°F) to -70°C (-94°F) are available.
To complete the positive environmental impacts, the new desiccant dryers are fitted with unique exhaust air silencers significantly reducing noise levels.
Mattei full suite of dryers is completed with its DDH range of heat regeneration adsorption models.
