New Range of Hoesch Filter Presses Offers Higher Quality, Lower Cost and Shorter Delivery Times
10 March 2008 12:07
A comprehensive redesign program has resulted in a new modular range of Hoesch filter presses available with improved quality and operation and shorter delivery times.
In 2006 Larox began a detailed development program to reduce the cost and improve the delivery time of the Hoesch range of filter presses, while at the same time, maintaining or improving on the well known very high technological standards and quality associated with all Larox products.
The goals were achieved by developing a modular design with standardized options. Common components are now used for both the side bar and overhead beam presses. This benefits the customer who not only now has access to competitive prices and deliveries for the filters but, if he has different filter types, he can now use the common spare parts thus minimizing the total spare parts stock level.
The following areas of improvement are of note:
1. All drives (plate shifter, washing device and swivel plates) are now installed with electrical motors so that additional hydraulic distribution (with the added complexity and potential for failure) is no longer needed for these items.
2. All moving parts are now located as far as possible outside of the product wetted areas to prevent both corrosion and product contamination.
3. Previous designs of the Hoesch presses left the chain of the plate shifter uncovered where it could be exposed to the environment or process fluids such as wash water and aggressive slurry ingredients. In the new designs the chain is integrated in the side bar design and is fully protected, thus reducing maintenance and extending the lifetime of the chain.
4. Using Larox knowhow the weak point in a many existing side bar presses on the market, the connection between the side bars, head piece and especially the cross head, has been eliminated. Larox has designed the new filter generation according to the new Eurocode 3 regulations together with the aid of FEM (finite element method) calculations. The resulting design ensures all structural components will last for the lifetime of the filter. The filter designs were also subjected to an extensive risk assessment to minimize the risk of damage to workers and machines.
5. A larger 2,000mm x 2,000mm plate has been developed for both side bar and overhead beam designs and the operating pressure range is now increased to 30Bar for the side bar design.
6. The levels for the machine control have been standardized to offer the customer a simple and competitive choice. With the fully controlled version the filter can be operated without any additional signals from the process. This version is included in the standard design. A PID or a simple terminal box version can be ordered as options. These customer tailored solutions reduce the risk of programming and logical failures and eliminate the need for extensive programming on site.
In addition to the new product design program, Larox has also invested in developing a world wide supply network whereby we are now able to deliver filters within a short time, while reducing shipping costs by completing manufacture closer to the point of use.
The Hoesch range of membrane filter presses is fully supported by the Larox Service group, the most comprehensive and experienced network in the industry, covering the world with operations in over 40 countries and providing reliable support throughout the entire lifecycle of the product – 'Performance for Life'.
Larox is committed to helping its clients meet the following goals:
- Reduced lifetime production costs – especially energy based costs
- Improved product quality, value and consistency
- Improved safety, health and environmental performance
- Improved yield and productivity
