ALPHA EXTRACTION PRESS
Modern laundries require machines with very high productivity, lowest use of resources and best hygienic conditions. With the further development of the JENSEN water extraction presses, JENSEN has taken this into account and meets these requirements. The previous press design was completely revised and optimized. The result is the new generation press JENSEN SEPPlus. Through innovation, JENSEN sets new standards in the field of water extraction technology. The JENSEN know-how for this further development is based on more than 30 years of experience in the construction of presses and more than 2500 extraction units built (status 2015). Hardly any other manufacturer can benefit from such an extensive wealth of experience.
JENSEN presses now offer a variety of new developments which once again improve the efficiency, reliability, userfriendliness and durability. These new developments include an innovative screw connection of posts, an optimized cushion fastening, an electronic level control of the cushion with automatic refilling as well as a new software which offers an even better operation and an even more comprehensive data collection. Furthermore, the product range now includes an additional press size for linen batches of up to 120 kg. Just like the SEP 100 SHD, the SEP 120 SHD has a basket with a diameter of 1300 mm and reaches, in connection with a pressure of up to 57 bar, exceptionally low residual moistures. With the SEP 90 SHD, JENSEN was the first manufacturer to develop a press with such a large basket diameter. JENSEN has again set new standards in water extraction technology.
Design and Construction
Top plate and hydraulic system
The top plate of the press is made of extremely stable spheroidal graphite cast iron. This top part bears the hydraulic cylinder and the hydraulic unit as well as the respective control. The hydraulic system includes an infinitely variable pump which is extremely low-wear and highly efficient, compared to conventional systems.
Innovative TopDrain-system
The base plate is made of a solid steel block and provided with a durable anticorrosive. The patented TopDrain-System is mounted onto this base plate. The TopDrain-System is a closed drainage system of stainless steel. The extracted liquor is fed into either a separate, easily accessible recovery tank or, if combined with a tankless JENSEN tunnel washer SL (pat.), directly back to the rinse process of the batch washer without the use of any intermediate buffer tanks. Standing water is avoided and an outstanding hygiene is guaranteed. The TopDrain-System also has extraction pipes with larger diameters which provide an even faster discharge of the pressed-out liquor. Thanks to this, even lower residual moisture values can be reached for the press cakes. The stainless steel drainage plate can also be easily removed for cleaning.
Posts
The top plate and base plate are connected via four strong posts. For the SEPPlus a new post screw connection with special tensioning elements was developed. With this screw connection it is possible to reach a higher and more precise pretension. Furthermore, the corrosion protection of the posts and of the round nuts has been optimized by a teflonbased coating.
Press cushion
The press cushion is installed on the press plate by means of a new clamping device. The press plate is on the bottom end of the hydraulic cylinder. Thanks to the optimized geometry of the stainless steel clamping ring, the cushion is better supported and the lifetime of the cushion is thereby increased. The clamping ring also has a new outer coating made of an extremely stable synthetic material which improves the sliding properties within the basket. The position control of the press plate on the SEPPlus is infinitely variable. For this an innovative ultrasonic sensor is used. Thanks to a highly resistant hard rubber coating, the plate itself has optimal protection against corrosion.
The press cushion is made of wear-resistant special rubber and is filled with water. The concave shaped press base ensures best extraction results with the most gentle treatment of linen, even under high pressure. Furthermore, an electronic level control of the cushion with automatic refilling was developed for the SEPPlus to ensure optimum filling of the cushion and constant extraction results. Also the press cushion portfolio has been extended: The new optional 2K press cushion (patent pending) with its unique two-component rubber mixture offers even more individual adjustment to the customer requirements and different applications. The two components have been adjusted perfectly to the differently affected functional areas of the press cushion which extend the lifetime of the cushion correspondingly.
