Mattei Adsorption Dryers
Our adsorption (desiccant) dryers feature a compact design that can be installed as needed at the most critical plant locations. These dryers are heatless but still produce superior pressure dew points at low purge rates by using desiccant material to attract and adsorb water molecules.
DD Series
Mattei's DD Series dryers are the optimal solution for thousands of compressed air applications across a number of different industries.
Adsorption is a process whereby specific molecules (the adsorbate) adhere to the surface of a highly porous solid (the adsorbent) by electrostatic and molecular forces. The adsorbent has a specific pore structure which will be a combination of larger or macro pores, slightly smaller or mesopores, or very small pores known as micro pores.
BENEFITS OF DD DRYERS
The use of Mattei’s dryers removes the condensate from the air, preventing any damage to the compressed air distribution system. Mattei DD dryers reliably give you:

- more for your money - everything needed for installation is in the box
- moisture and particulate protection of your production process
- lower life cycle costs - low energy costs and simplified maintenance
- built in dew point monitoring (optional)
- space saving - models up to DD 130 can be easily wall mounted
- safe and quiet operation
- flows from 5 to 1900 Nm3/h ( 3 to 1110 scfm) at 7 barg operating pressure
- peace of mind - the most reliable product of its kind
Designed for use in the compressor room, at the point of application or integrated into your original equipment, DD dryers are an effective solution to the problems caused by contaminated compressed air.
DDH Series
A centrifugal blower and high efficiency heater eliminates the use of valuable compressed air to be used for desiccant regeneration.
The completely automatic drying system uses blower to pull ambient air and pass it through the heater. This hot air stream flows opposite to drying flow direction. Hot air above 200 °C regenerates the moisture inside desiccant bed and strips it completely of all moisture. The advanced control system monitors the dew point and adjusts the regeneration accordingly thereby providing valuable energy savings. 
FEATURES OF DDH DRYERS
- dew point monitoring and control
- computer control, display status
- display alarms and pressure
- remote start/stop,low pressure alarm
- minimum pressure monitoring valve
- high pressure switches and alarms
- externally heated or heatless dryer functions integrated to the DDH dryers
We can deliver complete BEKOMAT electronically level-controlled condensate drains and service kits as well. The BEKOMAT range provides the 12, 13, 14 and 16 standard drains for virtually every application, which are not just the correct solution, rather more also the most suitable low-energy solution. The integrated capacitive sensor for level-controlled condensate discharge helps save energy and enhances efficiency – which is what you would expect from a BEKOMAT.
The regular maintenance was carried out in 2 consecutive years by the team of TUNGS-STAR on an ABC Horizon 1400 compressor at Plastipak Romania SRL in Urlati. The 40 bar PET compressor is powered by a 280 kW motor equipped with VSD. It has 3 stages with 4 horizontally opposed cylinders.
New 15 kW MATTEI compressor was installed next to an old 7.5 kW Mattei compressor to assure the increased production of a local company.
