One way for drugmakers to reduce costs and remain competitive is to increase the efficiency of their production lines. Personnel
can reevaluate their equipment to make sure that valuable ingredients are not wasted and mechanical failures are infrequent.
Mindful of the pressures on the industry, equipment vendors seek to develop reliable products that will improve their clients'
operations. This month's products are designed to aid various parts of the manufacturing process. The Titus Company's nitrogen
generators perform precise separations. A metering pump from Moyno is intended to offer accuracy and gentle handling. DENSO's
series of cleanroom robots are designed for repeatability and flexibility.
Nitrogen generators offer efficiency
The TN2 series of nitrogen generators from The Titus Company (Morgantown, PA) is designed for high efficiency. Each unit includes
Air Products and Chemicals's (St. Louis, MO) PRISM hollow-fiber nitrogen membrane, which enables precise separation and high
selectivity. The membrane reduces the amount of lost nitrogen and allows the device to create nitrogen that is 99.9% pure,
says Jim Bowers, a product manager at Titus. In addition, the membrane resists oil-vapor contamination and does not require
compressed air to be predried.

The TN2 generators are available in three configurations. The TN2 Essentials model is appropriate for small applications that
do not require high purity. The TN2 Total unit is available as a wall-mount enclosure and enables operators to fine-tune the
purity and amount of nitrogen generated. A fully self-contained model includes a compressor and air receiver for facilities
that lack a reliable source of compressed air.

Metering pump provides variable-speed control
Moyno (Springfield, OH) offers a metering pump with new pumping elements that enable the machine to provide flows of 0.1–400
gal/h. The metering pump is also available with integral VFD motor controls that enable variable speed, improve metering accuracy
and repeatability, and enable operators to compensate for slip and obtain the desired flow rate.

The progressing-cavity pump imparts low shear, flows products gently into the discharge piping, and changes the fluid velocity
only slightly. The unit is thus appropriate for sensitive products that require gentle handling.
Cleanroom robots have long reach
The VM series cleanroom robots from DENSO (Long Beach, CA) have long, slim arms that can reach around equipment or tooling
and into small spaces. The units are available with reaches from 1000 to 1300 mm, a payload of 10 kg, and standard cycle times
of 0.89–0.95 s. The six-axis, articulated arms have a repeatability of ±0.050 to ±0.070 mm that makes them appropriate for
applications requiring precision. The robots' maximum allowable moment of inertia is greater than that of conventional robots
and allows operators to choose from a wide range of end-effectors. These features bring the series flexibility.

Despite their long reach, the VM series units have a small footprint. Unlike many robots, the devices' wiring and air lines
are concealed within the arms. This design helps save floor space and enables the robots to be integrated easily into a production
