Compared to standard dustcollector cartridge filters, the HemiPleat filter typically doubles the life at half the pressure drop, according to the manufacturer. The key to the filter’s performance is a patent-pending pleating technology that has never before been used in the manufacture of a cylindrical dust collection filter. An innovative media pack design holds the pleats of the cartridge open, making virtually all the media surface available for filtration. The wide, uniform spacing results in lower pressure drop for more efficient performance.

Conventional ball valves utilize elastomeric or mechanical stem seals to contain the transmitted medium. If these seals fail, the medium escapes to the environment. This is a grave concern if the medium is a potential environmental pollutant or health hazard. The Roetelmann design eliminates this potential by encapsulating the stem and seals in a welded canister, should the seals fail the medium cannot escape to the atmosphere. Previous designs were unable to provide an indication that the internal ball had rotated to the desired open or closed position when the valve was actuated.

The advanced TS4000 Toxic Gas Monitoring System combines a highly intelligent microprocessor-based design with exceptionally reliable and rugged electrochemical sensors in an explosion-proof housing. The intrinsically-safe design of its interface module supports sensor field replacement without the need for special tools or hot work permits. Other features include longdistance remote mounting up to 2,000 ft, dual redundant MODBUS communications, 8-A relays, three-digit display, 4–20-mA output, and indication of remaining sensor life.

The DeltaFlow 2.0 system produces ultrapure water without the use of hazardous ion exchange regeneration chemicals by employing three membrane separation technologies — reverse osmosis (RO), GTM membrane degasification unit and electrodeionization (EDI). The system features a new GTM module design with larger, more-efficient contactors that can be configured to produce water containing less than 5 ppb dissolved oxygen.

Types RSL and RSH seals provide greater sealing efficiencies due to a combination of seal lip and additional labyrinth formed by a gap between the tapered rubber part and the inner ring shoulder. Use of uniquely shaped sheet steel reinforces the rubber material, which keeps the seal stiff within the lean design. High-precision manufacture of seal counterfaces and specially engineered recesses in inner ring shoulders help to reduce seal lip wear.

The Tetra Detector Array uses state-of-the-art GPC/SEC multiple detection technology for the characterization of natural and synthetic polymers, biopolymers and proteins. It consists of a patent-pending low-angle light scattering (LALS) detector, four capillary viscometer detector, refractometer and selectable wavelength UV/VIS. All the detectors, as well as the GPC columns, are contained within a heated oven compartment with temperature control to 80°C, thus eliminating temperature variations.

Designed for use on glass-lined reactors where batch-to-batch cleanability is important, the Clean Valve is a bottom-flush valve that is easy to operate and clean. The self-draining valve allows for a variety of functions (including sampling, gas dispersion, maintenance, etc.) without the need to interrupt the process and without dismantling the valve. The glass-linedsteel design ensures no metal contamination of the process fluid and enables use across a wide temperature and pressure range.

The 410/412 series large-diameter butterfly valve features a bi-directional, bubble-tight shutoff pressure rating of 150 psi, high Cv ratings, heavyduty construction, reliability and long service life. The 410 model, a wafer-style body, is available in sizes from 24 in. to 36 in. The 412 model, a double-flanged style body, is available in sizes from 24 in to 48 in. Valve bodies are offered in cast and ductile iron, cast steel and stainless steel and comply with ASME/ANSI 125/150 flange drilling standards.

The MECO custom shaft seals reduce solvent vapor loss from rotating extractor, dryer and reactor driveshafts, resulting in local solvent concentrations of 100 ppm or less. Fully split seals can be installed on existing machinery with minimal downtime. Operator-adjustable seals often allow adjustment while machinery continues to run. Patented seal designs accommodate 6 mm and more of diametric shaft run-out.

The stainless-steel Micro C-Series (MCeccentric) disc pump line extends this manufacturer’s operating range from 0.03 to 158.5 gal/min (0.1 to 600 L/min). The pumps’ gentle, low-shear handling of fluids accommodates a variety of chemical-process and metering applications. Sealless technology assures zero leakage and provides consistent delivery and pressure over long periods of time.
