The ECO SB range of filter presses has been designed to respond to the market’s need for flexibility by combining a high output with ease of use and fitness for a very wide range of applications, such as the chemical and pharmaceutical industries. Its construction, with two pulled tie rods, provides access from the top to the plate pack and makes for flexible operation and handling. In addition, the separation between the plate-holding effort and the thrusting effort makes for easier structural use. The machine is very fast at the opening and closing stages and is perfectly reliable; it can be used unattended, 24 hours a day. The plate-handling system can be full, with packs or simple, and can be designed and customised to suit the client’s needs or specific applications. Finally, the effective cake separator, with adjustable force and timing systems, safely separates the panels. Ideal for use in unattended applications in processing industries.

Hydro-pneumatic bag system: : the low-pressure (max 30 bar) bag closing system evenly distributes efforts, thus avoiding concentrated stress or warping which could damage the frame and which are the main source of wear in the cloths. In addition to the structural benefits, this system does not use a hydraulic unit or a high-pressure cylinder, which are the main, unavoidable sources of reduced reliability in the long run.

Adjusting and locking screws: the adjusting and locking system for the movable head uses specially designed adjusting screws, made of stainless steel with an extremely high yield point. The screws are mechanically timed and operated by inverters. The system withstands the stress applied by pressure in a perfectly even and well-balanced way, resulting in lower stress on the whole machine and therefore in a longer life for both plates and cloths.

Automatic cloth washing system:it is a veritable robot arm which accommodates a high-pressure water jet system. The arm, which runs all along the machine, automatically washes the cloths, one by one. The very high-pressure water jet can remove any kind of impurity so the cloth will be ready to filter and drain again and the plant will be ready to dehydrate the sludge again.

Double feeding system: depending on the material to be filtered or the work cycle, the test laboratory will select one of two opposing feeding systems to deliver the best results in terms of cycle time and solids in the panel.



Safety barriers: at the client’s request, safety is provided by photoelectric barriers installed at the sides of the plate pack or by quickly-removable gates (usually, it is the client that analyses the space around the machine with ASTEC’s advice and assistance).



Quick opening system: the plates are joined together by stainless steel pads; because of such system, the opening and closing operations are very quick, and the distance at which the cake is separated is always the right one.



Knockout carousel: the plate pack is knocked out by a very safe quick-inverter-operated carousel. Such system picks up the plates, one by one, and carries them near the previously opened pack.



Shaking system: because of the powerful pneumatic cylinders provided with this system, the number of times the plates are lifted and lowered on top of the side-member and the impact can be programmed. So the separation of the cake will take place neatly.



Plates: depending on the type and temperature of the fluid to be filtered, the plates may be supplied in different materials or thickness. Polypropylene, copolymer or cast iron are just a few of such materials.




Water trap:the cloth washwater is collected in an automatic, tilting metal bowl which opens up to dump the cakes and closes back just after, so, as well as collecting the cloth washwater, it protects the filtrate from the drops that might accidentally fall down during the process.


Monitoring system: the monitoring system is served by an integral PLC with a touch screen. Such smart system can manage any optional extra requested by the client, such as remote control of the machine, troubleshooting, processing statistics, Ethernet connection, and much more.
