Osmosis has been applied to the food industry for many years. Its use in wine-making has made it possible to obtain enriched musts with an increase in extracts.
Enomeccanica Bosio - who have been developing and applying advanced technologies exclusively for the wine-making industry for 40 years have worked over the last few years on the application of REVERSE OSMOSIS to musts and CROSS-FLOW FILTRATION on wines, achieving the two main targets the originally set themselves:

• 100% PRESERVATION of varietal aromas and flavours in musts.
• Limited OPERATING COSTS

A very special machine has been developed called HF/ET, with a balance kw / permeate yeld / operating costs that has never before been achieved on this type of plant. Its reliability and initial, and above-all operating-cost benefits make the HF/ET a cutting edge food & wine industry machine.


SOME FEATURES OF OUR MACHINES

• Operating from 0°C to any room temperature
• No centrifugal pumps, just low-speed, high-flow pumps that optimize treatment without affecting the product.
• Minimal temperature variations during working of the must
• Output of between 20 and 2.600 litres+/hr of permeate
• EC standard machines with safety devices certified for 24 hour-a-day operation
• Tailor-made plant design
• Oversized hydraulic system for the HF and HF/ET models, so their power can be increased if necessary with the addition of extra membranes

The following is a description of the safety devices which have been installed on the HF / ET and HF Series Reverse Osmosis Units in order to improve their performance.


5 x LOW PRESSURE CIRCUIT SAFETY DEVICES

• Automatic machine stoppage with filter blockage
• Automatic machine stoppage with liquid shortage
• Automatic machine stoppage with supply pressure of more than 2-3 bar, to protect the membranes and pump
• CAT high pressure pump start-up timer to evacuate all the air in the unit before it enters into operation;
• Automatic machine stoppage in the event of accidental closure of supply and drainage valves.

• 80-bar high pressure transmitter 85-bar mechanical
• TELEMECANIQUE safety pressure switch
• 90-bar I.S.P.E.S.L.-approved mechanical safety valve
• Instant shut-down safety device fitted to safety valve
• Automatic machine stoppage in the event of any leakage anywhere in the unit
• Special safety device installed on maximum pressure regulation valve
• Alarm device on CRA pump sea
