Cranemat® and Revonex™ are polymeric wet-laid, calendered non-woven, manufactured in Pittsfield, Massachusetts and Quimperle, France. It is a membrane support substrate of choice, specified by membrane manufacturers world-wide. It has a reproducibly smooth uniform surface and controlled porosity that allows for high quality membrane casting.
It has been used across the membrane filtration spectrum including Microfiltration, Ultrafiltration, Nanofiltration, Reverse Osmosis, and other specialty applications. Critical characteristics such as porosity, thickness and basis weight, as well as roll width and length, are routinely tailored to meet customer’s specific needs. The employees of Gessner Technical Materials pride themselves in caring about the of success of their customers, being responsive to customer needs and providing an excellent product in a timely fashion.
For 70 years Naltex™ Extruded Netting, our premier diamond net, has delivered high-performance results in environments needing filtration, separation, and protection.
The biplanar configuration of Naltex Extruded Netting allows excellent flow as feed water spacers in Reverse Osmosis (RO) applications. Specific strand alignment achieves the turbulence needed to protect and maintain the systems membranes. In addition to RO applications, Naltex can be used in many industrial applications including bags and racks for food processing and plastic mesh for protection and packaging applications. Naltex is also an ideal composite flow media for resin distribution in applications like wind turbine blade manufacturing.
Naltex™ diamond mesh continues to improve the process of extruding through counter-rotating die heads. Over the years we've introduced nets with new resins, varied strand count and cross section, and a range of strand angles, offering customers different looks, feels, strengths and additional functionality. We custom-develop extruded netting to meet your specific industrial performance requirements for demanding applications in the filtration market.
Naltex™ Feed Spacers, a bi-planar mesh with thermally bonded strand intersections, is the most widely utilized net in the filtration industry for feed spacers. Specialized engineering-grade Naltex nets have unmatched performance in high-end filtration systems. Our premier line of Naltex Feed Spacers support and protect thin film composite (TFC) membranes in RO spiral wound element filters. Filtration manufacturers around the world seeking high performance feed spacers turn to our full line of custom designed diamond netting with varying geometries, specialty resins and optimal flow characteristics. Naltex Feed Spacers are used in nearly all TFC membrane filtration applications, ranging from HRO to municipal water and industrial process filtration.
Coretec™ Permeate Tubes include a wide range of high-performance components, made from advanced engineering-grade resins and stainless steel. Our filtration products include center tubes for reverse-osmosis water filters, feed spacers, cores, pressure vessels, machined parts, adapters. and interconnectors. Coretec high performance permeate tubes are made from engineering grade resins and are custom designed to deliver unmatched performance and quality. Coretec permeate tubes are used in a wide variety of spiral wound membrane filters ranging from small HRO products up to large volume municipal and industrial membrane systems used in water and process filtration applications.
Coretec™ Machined Parts are made from engineering grade materials and are custom designed to deliver unmatched performance and quality. Uses include a wide variety of spiral wound membrane filters ranging from small HRO to large volume municipal and industrial membranes for both water and process filtration applications.
Clean water is a necessity for the survival of humankind. Today clean water is a diminishing resource, making water purification technology more important than ever. Our Cranemat products are especially designed to meet customer’s unique specifications for membrane support backing used in reverse osmosis for seawater, brackish water, tap water, residential and waste water filtration segments.
Applications like Juice and Dairy processing can deal with thicker more viscous fluids, as they separate out solids or proteins, perhaps under higher pressures, requiring frequent cleaning cycles. A more robust, stiffer membrane is often necessary to handle these challenging conditions. These membranes require a specialized backing fabric which can hold up to their demanding process parameters.
The Cranemat line also offers stronger membrane backing substrates with higher basis weight and thicker caliper, optimized for excellent membrane adhesion, for these and other specialty applications.
Gessner Technical Materials is focused on meeting the needs of novel and emerging applications. For example, our materials are now used to bond dissimilar substrates like a bulk nonwoven to microporous film, or to serve as printing substrate for conductive networks or for nanoparticle immobilization. Gessner Technical Material’s R&D group continues to work closely with researchers to develop and supply materials for these new and emerging markets.
As we strive together for a more sustainable world end users are requiring water filtration products that are more efficient and need to withstand increasingly harsh and diverse conditions of service. Our Cranemat® product series is the solution for…
