The technically advanced LoKr reverse rupture disk (photo) delivers a best-in-class flow-resistance factor, KR, to maximize pressure-relieving performance while delivering superior reliability and service life. The disk’s architecture has been refined and optimized to improve performance in three key areas:…
In June, the newly developed, dust-tight OEB version of the DDSR20 2.0 twin-screw feeder (photo) passed the highest occupational exposure bands (OEB) classification certification, OEB5. OEB classifications are used to grade substances accurately into “classes” or “ranges” based on the…
The new Sensor Bypass Armature Modular (BAM; photo) accommodates all potentiometric, amperometric and conductivity sensors from this company for water treatment. It is simply installed in a bypass of the main process line. The modules of the armature and the…
The Delta Hybrid series (photo) offers an innovative solution for the pneumatic conveying of sensitive, powdery and granular media. The rotary lobe compressors or screw blowers can offer maximum energy efficiency, minimum lifecycle costs, 100% pure and reliable process air…
At Powtech last month, this company presented completely new, more wear-resistant screen cloths that, compared to previous standard cloths, achieve an increased service life with abrasive bulk materials. Matched to the wire thickness and mesh size, the screen cloths are…
With a minimal footprint of approximately 1 m², the compact Aircenter systems (photo) are available for flowrates from 0.34 to 2.7 m³/min and also provide application-specific compressed-air treatment and storage. All Aircenter models are characterized by their exceptional efficiency. At…
In crossflow membrane filtration (CMF), feed flow is parallel to the filtration surface (rather than perpendicular to it, as in conventional filtration). During a given pass, a portion of the feed permeates the membrane, while a larger portion is retained…
Fouling of heat exchanger surfaces reduces thermal efficiency. An improved understanding of fouling and the design factors that affect it can help ensure that heat exchange occurs during normal operating conditions Using tubular heat exchangers is an efficient and reliable…
This C Series heat exchanger (photo) replaced an older shell-and-tube design that had high operating costs, due to a 2.4 psi pressure drop. While both old and new units have the same capabilities, the new C Series pressure drop is…
During vessel breakout activities, plants should pay close attention to the design of the washers used on bolted flanges. A simple change in this area can help to reduce downtime and improve safety Bolted flanges on vessels, and their associated…
