DRYING, FILTRATION AND STORAGE

The Air Treatment Atmospheric air always contains water vapour and impurities. For the final user it is necessary to get a compressed air supply, free from condensate and contaminating particles, such as oil and dust. If such contaminations should come in direct contact with the final product, the resulting costs would be extremely high and a solution that could have been practical and inexpensive at the design stage would then be very costly. The aim of Mattei’s compressors is to provide quality compressed air, clean and dry, A quality compressed air supply needs to be dry. The use of...

Oil-Water Separator The condensed water inside the compression chamber will contain particles of the oil used as compressor lubricant/coolant in addition to those airborne contaminants including hydrocarbons drawn in to the compressor from the atmosphere. To discharge the water into the drainage, according to the regulations required in the country of installation, the condensate will first have to be purified. Mattei’s MOS Series separators are used to this end, because they are easy to install and are manufactured with recyclable materials. These accessories guarantee excellent...

Compressed air filtration Mattei filters, with five filtering elements of different grades, allow you to achieve the highest compressed air quality standards, according to ISO 8573-1:2010. GRADE C2 OIL REMOVING FILTER It is suitable as initial protection for a compressed air system or a refrigerant dryer, for general application in pneumatic devices, as a prefilter for “C2” grade filters and as a post-filter for adsorption dryers. Maximum working temperature: 100 °C. Removal of solid particles It is suitable to remove large oil quantities. Maximum working temperature 100 °C. Removal of...

ACTIVATED CARBON FILTER This filter is required for an effective retention of the oil residue, around 99,99%, and delivers technically oil free air. Maximum working temperature 100 °C. It is used to eliminate oil vapours and odours and for the final treatment of compressed air. The filtering element is made of activated carbon, with an external steel mesh. The adsorption principle removes vapours and residual odours of the oil retention process. A grade C1 filter should be always placed before it. Maximum working temperature 60 °C. Maximum liquid residue mg/m3 0,003 Removal of solid...

PURE AIR GUARANTEED BY A SUPERIOR PRODUCT In modern manufacturing processes compressed air plays the role of a safe, reliable and economic energy supply. The air delivered by compressors must be treated to obtain quality air. Otherwise, the life of pneumatic tools and the quality of finished products will be jeopardised. DIFFERENTIAL GAUGE Two different types of contaminants may seriously affect the quality of compressed air: 1) atmospheric contaminants 2) plant contaminants Regarding atmospheric pollution, a cubic metre of urban compressed air at 7 bar can contain one thousand million...

REFRIGERANT DRYERS ELECTRICAL ENERGY SAVING: a reduced pressure drop through the dryer has a direct effect on reducing the running costs of the compressed air system of between 5 and 8%. CONTROL PANEL: guarantee consistent performance also in intermittent working conditions. CONDENSER: ensures maximum performance of the refrigerant circuit and the ability to operate with changes in the ambient conditions. ALU-DRY MODULE: has a direct effect on reducing energy consumption. CONDENSATE DRAIN: adjustable electronic condensate drain with timer. INTEGRATED “HOT GAS” BY-PASS VALVE prevents the...

ENERGY SAVING: the refrigerant compressor of EMD dryers adjusts to the load demand, allowing up to 80% energy saving under normal operating conditions. HIGH RELIABILITY: ensured by a simple refrigerant circuit and by thermostatically controlled dewpoint. SURE GUARANTEEED QUALITY: remarkably low and constant dewpoint. READY TO USE: unlike traditional thermal mass systems, EMD dryers do not need pre-switching. They may be left ‘on’ without current leakage. ECOLOGICALLY SAFE: the silica thermal mass and the refrigerating gas are absolutely nontoxic and easy to dispose of. THERMAL MASS...

HIGH-QUALITY COMPRESSED DRY AIR: alumina-based technology. Alumina is an absorbent material that guarantees consistently high performance in delivering compressed air purity. ULTRA-COMPACT AND LIGHTWEIGHT DESIGN: ease of installation and maintenance. HIGHLY EFFICIENT PLC CONTROL SYSTEM: the removal of moisture and contaminant particles is rigorously controlled. COMPRESSOR SYNCHRONISATION: starts and stops the dryer with a signal from the compressor, eliminating purge loss when drying is not required. ENERGY SAVING: advanced design limits regeneration purge air usage to around 15%....
