Portable steam-sampling cart requires no water
Budzar (Willoughby, OH) recently introduced a portable, sanitary steam-sampling cart that operates without cooling water. The cart includes a small refrigeration unit that creates cooling capacity for the condensate, thus removing the need for a water source, according to Adrian Pop, Budzar’s engineering manager. Operators can move the cart to any sampling point near a wall outlet.
The cart incorporates a retaining tank that facilitates steam sterilization. A steam-rated hose connects to the condensate outlet, enabling the operator to handle the sterilization process safely. If the tank fills up with condensate, it can be removed and drained easily. A pressure transducer in the steam line does not allow the operator to disconnect the hose until the pressure in the steam loop is zero. In addition, a programmable logic control (PLC) guides the operator through the sampling steps, thereby reducing the amount of training needed.
Self-protecting blower ensures longevity
The DB 166C and DB 236C CompaK Plus blowers from Kaeser Compressors (Fredericksburg, VA) include an Omega Control Basic controller module that operates and monitors the units. Sensors transmit pressure and temperature readings to the controller, which shuts down the blower if measurements exceed specified levels, thereby increasing the blowers’ longevity.
Each unit includes a blower, motor, drive, silencers, controls, and a full enclosure. The enclosure attenuates noise, protects the package from dirt and dust, and keeps the blower properly ventilated. The integrated package is designed to facilitate maintenance and installation. Operators need only make a piping connection and an electrical connection to set up the blowers.
The DB 166C and DB 236 units have a small footprint and are easily moved. The blowers are appropriate for pneumatic conveying of process components, chemicals, bulk powders, and pills.
