1 Nitor Cross-Flow Filtration Systems Designed specifically for wine

2 Nitor Cross-Flow filtration systems The Padovan NITOR Cross-Flow Filtration System was developed in 1989 as an answer to the growing issues posed by Diatomaceous Earth in Europe. TMCI Padovan (Italy) experimented for several years with various solutions to these problems leading to the development of a unique system of cross-flow filtration, which is both respectful of the specific organoleptic qualities of wine, while also being highly efficient. Its all in the membranes! 2

3 Nitor Cross-Flow filtration systems The specific advantages of using cross-flow filtration technology are: No Diatomaceous Earth usage. No negative D.E. flavor effects on the wine. Minimized labor costs as systems can be automated. Greatly reduced wine losses during filtration. 3

4 Nitor Cross-Flow filtration systems Historically there were some disadvantages seen with cross-flow filtration technology: Limited working life of the filtration membranes. Poor efficiency of the filtration over extended time periods especially when filtering wines with high NTU levels and/or the presence of Bentonite. Problematic heating of the wine during filtration. 4

5 TMCI Padovan Solutions The membranes used by Padovan are specifically designed for very long life, this is reaffirmed by the length of the warranty offered which is 3 years. Filtration efficiency is optimized by the on-board PLC, using a managed approach which is the only way to efficiently filter wine. Issues of heating during filtration are solved by the unique modular approach to filtration construction. 5

8 Membranes Two major types seen in the wine industry. Ceramic Organic 8

9 General Rules for Organic Membranes Thinner membrane capillary walls give shorter useful life and less chemical washings allowable. Thinner membrane capillary walls give lower mechanical resistance. Smaller internal diameters will not work well with products rich in suspended solids. 9

10 Recirculation Flow Asymmetrical Pores Symmetrical Pores Filtrate Flow Filtrate Flow 10

11 PES FEATURES Inherently hydrophilic Low protein binding characteristics Good chemical compatibility Excellent flow rates The hydrophilic nature of PES means no added surfactants are used to increase wettability. Superior burst strength Thermal resistance Highly microporous Durable 11

12 Nitor Cross-Flow filtration systems TMCI Padovan cross flow filtration systems use a unique polyolephin in the membrane construction with symmetrical pores and a nominal porosity of 0.2 microns. Membrane modules are assembled by Padovan for complete quality control. Proven longevity, several units with over 12 years continuous running without membrane replacement. Highly respectful of wine quality. Warranted for 3 years. 12

13 Nitor Cross-Flow filtration systems TMCI Padovan cross flow filtration systems are available in two versions each with distinct advantages. Nitor CAXL Series Fully Automatic (from 120 m² to 800m² ) Nitor Smart Fully Automatic (either 20 m², 40 m², 60 m² or 80m² ) 13

14 Nitor CAXL Series Fully Automatic The CAXL Series has the unique advantage of being expandable without changing the base machine configuration simply by adding modules composed of four membranes (80m 2 ). 14

15 Nitor CAXL Series Fully Automatic. MODULARITY This modularity gives several very significant advantages; 1. Expandability. CA XL series units can be expanded as standard all the way to 400m 2 2. Selectable surface area for small and large lots, a 400m 2 filter can also be used to filter very small lots of 800 liters or less. 3. Reliability as multiple recirculation pumps are used. 4. Less than 1 C temperature pick up, because of the use of low rotational speed pumps (1.450 rpm) giving low linear flow rates during recirculation. 15

17 Nitor CA XL Series Fully Automatic The CA XL Series has a high level of automation giving many advantages for process efficiency Fully automatic programmable back washing during filtration. Fully automated cleaning. Programmable flow rates. Data storage and retrieval. PLC optimized filtration efficiency. Programmable for end of cycle cleaning without operator. Selectable filtration surface area. On-board flow and integrity testing. Available in sizes from 80 m 2 to 400 m 2 17

18 Nitor CA XL Series Fully Automatic 18

19 CA XL Series advantages continued... 3 years membranes warranty. Independent of the cellar. Allen Bradley PLC as standard. Network integration possible. Efficient filtrations at high turbidity for extended time periods. Reduction in product losses thanks to scavenger filtration either by nitrogen or by valves. Inert gas sparging during filtration for less than 0.1mg/l dissolved oxygen pickup. 19

20 Optionals In-line filtrate turbidity monitoring and reporting. In-line filtrate addition dosing. Iso-baric configuration for sparkling wine filtration. Inlet/outlet manifolds for tank management and blending 20

21 Filtration...and TMCI Padovan Automation Fully automatic and programmable yet very simple and intuitive to operate. PLC control with multiple levels of password security. Automatic protection of membrane to prevent fouling. Designed to suit your needs. 21

22 Filtration...and TMCI Padovan Automation In house customization of touch screen software as required. Multiple password levels. Data recording and integration. US based back up of systems data. 22

23 Filtration...and TMCI Padovan Automation On screen real time graphing of the filtration process. Very simple operation. 23

24 Filtration...and TMCI Padovan Automation Maintenance and engineering access for remote assistance. 24

25 Nitor Smart Series Fully Automatic The Smart Series of Fully Automatic filters features the same level of automation of the CA Series. Designed for applications where space is at a premium. Fully automatic like the CA series. Fully independent of the cellar. Can be located easily by one person. Can be moved by forklift with built in channels. More filtration surface area per sq.ft of floor surface than any other system available. Available as either 20 m 2, 40m 2, 60 m 2 or 80m 2 25

26 Nitor Smart Series Fully Automatic 26

27 Optional turbidity meter Turbidity reading and control unit with automatic wine divertion when turbidity is above the prefixed value Stainless steel cell including two light sources and two miniaturized photocells. One cell is directly illuminated from a light source, while the other receives only the reflected light from particles suspended in the liquid. The reflected light and the direct light ratio is converted into a signal. This instrument is not sensitive to colour or temperature changes. Graduated display indicating the degree of turbidity in NTU units. 27
