Encapsulator handles highly potent products
The unit's dynamic airlock is protected by a high-efficiency particulate air (HEPA) filter and maintains operator exposure at the nanogram level.
The encapsulator incorporates a closed air system and does not require external venting. Screens protect the HEPA filters on the exhaust and inlet sides of the unit during operation. The HEPA filters keep the fan and plenums out of the contaminated area, Lawrence adds.
Factor-1 sensors withstand washdown environments
The Factor-1 "uprox+" proximity sensors from Turck (Minneapolis, MN) sense all metals at the same range. The devices are available with sensing ranges as high as 30 mm and barrel sizes from 12 to 30 mm.
The units are appropriate for washdown processes in the pharmaceutical industry. The sensors' cap is made of a liquid-crystal polymer that resists harsh chemicals. Double sealing protects the sensors against moisture ingress. The units' stainless steel construction resists continuous pressures of 145 psi. In addition, the sensors withstand temperatures from-40 to 100 °C.
Compact conveyor saves energy
The conveyor features "COAX" multistage ejector technology, which allows the unit to consume less air and energy than pneumatically driven vacuum conveyors. The conveyor operates with feed pressures of 58–87 psi and working temperatures of 0–140 °F. Thomas says the conveyor is designed for low flow rates (around 1200 lb/h).
The device is assembled with triclover-style band clamps. It can be quickly disassembled, cleaned, and reassembled in less than 20 min without tools, Thomas says. A 0.5-μm filter prevents powder from entering the vacuum pump.
