High-Tensile Strength, Stainless Steel Filter Screens
HIGH-TECHNOLOGY CORP. is the world’s leading supplier of filter screens for use with belt-type or ribbon- type continuous screen changers. Filter ribbons are furnished in rolls with a standard length of 120′ (36.5 meters) or 60’ (18.3 meters). The yield of such a roll is equivalent to several hundred ‘screen packs’ in a conventional screen changer and lasts many months in non-stop operation.
The filter screen used in HITECH™ screen changers is woven from high-tensile strength stainless steel wire, in the Reverse Dutch Twill pattern. Screens are ultra-sonically cleaned and packed in our plant in Hackensack, New Jersey and are available for immediate delivery world-wide.
HITECH™ filter ribbons can be used with all screen changers of similar design, and can be supplied in non-standard widths and lengths to suit the customer’s needs. We also supply filter screens for all other makes of ribbon-style screen changers. Please contact our screen department for more information.
