The new Xtreme (forged) head (photo) is designed for use with cone crushers in extremely demanding conditions, and complements this company’s Elect (traditional-cast) and Enhanced (heavy-duty) crusher heads for Nordberg MP800, MP1000, MP1250, HP800 and HP900 crushers. Forged as a…
This company’s sanitary vertical blenders (photo) are engineered for rapid homogenization and drying in delicate applications under vacuum. The design avoids the destructive effects of heat on unstable ingredients, and it promotes vaporization at lower temperatures during gentle agitation while…
Vartech Industrial System Cleaner (ISC; photo) provides turbine operators with a non-solvent-based solution for removing varnish and sludge in turbine-oil systems. Vartech ISC can be added directly to oil during operation to clean varnish and sludge before a scheduled oil…
DetaPipe (photo) is a new high-performance clad-metal pipe product designed for use in corrosive, high-temperature processing environments. DetaPipe is produced using a proprietary process that joins corrosion-resistant alloys, such as zirconium and titanium, to lower-cost, base metals, such as carbon…
The MAN-LC (photo) is said to be the only digital pressure gage available with IO-Link. The device includes two configurable outputs that form part of a standard instrument and may be custom-programmed by users as desired. The display screen features…
Flow Detective Plus (photo) is an electronic airflow-meter calibrator designed to measure the flow of air-sampling pumps to within 2% accuracy. It can calibrate within the airflow range of 20 to 5,000 mL/min to ensure correct flow. Compatible with this…
ParallelPro (photo) is a leveling tool designed for chemical-vapor-deposition (CVD) processes, or any equipment requiring precise parallelism. Equipped with wireless communications and a field-serviceable battery pack, the ParallelPro measures offset distance, parallelism and temperature. Measurements are transmitted via Bluetooth to…
Sequencing batch reactors (SBRs) are a variation on the activated sludge process in wastewater treatment. This article provides an overview of SBRs, including their history, current use and future outlook Sequencing batch reactors (SBRs) are a type of wastewater treatment…
