Designed to minimize risk and maximize productivity, this company’s ribbon blenders (photo) meet OSHA standards with safety shaft guards (no external moving parts) and limit switches that prevent operation of the agitator when any cover or manway is open. In…
The Series 2900 industrial control valves (photo) are suitable for food and beverage, packaged water heaters, pharmaceutical and general service applications, as well as wastewater applications with moderate pressure drops and temperatures from –20 to 400ºF. The Series 2900 features…
CellScrew is a patented cell-cultivation system for biotechnology laboratories, which is constructed fully of plant-based materials — a first for the industry. At launch, there are two different versions that differ in the size of the growth surface: the CS10k…
To ensure that wastewater discharge meets all compliance requirements, plants should adopt a multi-tiered approach, rather than assuming that the downstream treatment facilities can handle all potential contaminant loads Most industrial manufacturing facilities are required to meet strict limits on…
When evaluating capital projects in the chemical process industries (CPI), there are many scenarios in which there are important differences between the alternatives in terms of capital, operations and maintenance and decommissioning costs. In these cases, decisions must be made…
This company’s self-cleaning filters (photo) remove oversized particles from process or wastewater flows of up to 2,500 gal/min without filter elements or bags. Removing particulate matter enhances the quality of products, such as oil-based or latex paints, solvent-based or waterborne…
Using proper installation practices and adhering to maintenance schedules helps ensure reliable operation of safety-relief valves Safety-relief valves are critical components of any pressurized system. In fact, a functioning safety-relief valve could be the most important piece of equipment on…
