Misuse of Plant Air

By: Michael Camber

In our visits to plants we often find poor uses of compressed air.  Even though our business depends on selling and servicing compressors, we hate to see people running compressors when they don’t need to.  It’s energy wasted, and we devote much human energy to educating customers on saving electrical energy.

The Benefits of Adaptive Control Systems

By: Stephen Horne

In municipal and industrial wastewater treatment, there has been a shift from manual to automatic process control in order to increase efficiency and improve effluent quality. An increasingly popular approach includes installing a variable frequency drive (VFD) to constantly adjust the amount of air injected into the process to control dissolved oxygen, NH4, and/or NO3 in the wastewater treatment.  This approach works well from a process control standpoint. The additional benefits include: lower power cost and extended service life of the blowers.  VFDs offer great flexibility, but they have high purchase costs and there are still many applications in which they can be inefficient.

Blowers for air knives? Actually, it’s a very good idea.

By: Stephen Horne

Industrial air knives direct air flow toward a product and use the air’s velocity for product drying, cleaning, coating and cooling in many manufacturing and packaging plants. In their most simplistic form, holes are drilled into pipes. Involutes or air amplifier designs are used in more advanced systems. In either case, these applications require high air velocities but not high pressure. Continue reading “Blowers for air knives? Actually, it’s a very good idea.”
