Main applications of Technofilter products and processes in producing cognac/whisky beverages

• Polishing filtration before bottling

• Removal of excess amounts of metals (Ca, K, Fe, Cu,etc) for beverage stabilization

• Improvement of organoleptic properties of beverages.

Features	Advantages
High-quality finishing of inner and outer surfaces.	Steadily high quality of beverages
Easy access to internal cavities for visual inspection and washing.	Smooth start-up, maintenance of prescribed pressures at the input and output of the system No hydraulic blows
No hidden or hard-to-reach cavities owing to          extra lightweight spacer.	Optimum set of options, compact size Full exhaustion of service life of filter         elements
No stagnant zones.	Touch pad for real-time control of all filtration          parameters.
Complete evacuation of liquid through drain          valve.	Cleaning of filter elements with high-purity         water or reconditioning with washing         solutions directly inside the system without         using any extra pump.
Increased accuracy and finishing of nests for        adaptors and of surfaces for sealing parts        ensure high impermeability of boundaries        between the feed, the filtrate and the outer        environment.	Removal of residual cognac with sterile          compressed air
Simplified on-site assembly owing to hinged         connection of pipe sockets to the base. The         filter holder is provided with pressure gages         for monitoring of flow resistance.	Reliable component parts

 
Brief specification of Technofilter filter elements used for pre filtration and final filtration of cognac/whisky beverages.

Grade	Filter medium	Retention efficiency, um	Properties	Brief description
EPVg.P	100% chemically resistant polypropylene (pH 1-14)	0.5 to 20	Depth	Pleated Stable rigid matrix, high retention efficiency, multiple reconditioning, operating temp of up to 90 Used for pre filtration and final filtration.
EPV.S	Microglass fibre	0.5/0.9	Depth Pleated	Stable rigid matrix, high porosity, absolute retention capacity, multiple reconditioning, operating temperature of up to 100Ã,increased dirt holding capacity and service life. Used as a final filter.
EPV.STs	Combination of micro glass fibres, cellulose and polypropylene	1.0; 0.8	Depth Pleated	Stable rigid matrix, high porosity, absolute retention capacity, multiple reconditioning, operating temperature of up to 100Ã, increased dirt holding capacity and service life. Used as a final filter.
EPM.PS	Polyethersulfone	0.2; 0.45; 0.65	Membrane Pleated	Broad chemical compatibility (pH 1 to 14), long service life resulting from high porosity, asymmetric structure of the membrane and  increased surface area of up to 0.75 m2/250 mm,multiple reconditioning, superior stable product quality. Used only as a final filter in combination with an efficient prfilter having a high dirt-holding capacity.
