Laird & Company has been pioneering and perfecting Applejack brandy for 325 years. In 1698, William Laird immigrated from County Fyfe, Scotland to Monmouth County, New Jersey, bringing nothing but the distillation skills of his homeland with him. Keen to experiment with the ingredients of the New World, William began to dabble in the distillation of the most abundant crop in the area – apples.
As part of its ongoing corporate initiative to find ways to reduce its energy bills, and the costly impact on the bottom line, a cleaning products plant, located southwest of Chicago, recently focused on improving their compressed air system operation. This company is a global leader in water, hygiene and infection prevention solutions and services. This article discussed their efforts to improve the operation of their compressed air system by implementing an innovative compressed air monitoring and control system.
There were two situations brought to our attention. The first was that production at times was having to slow down, or even stop, due to compressed air system pressure falling below the required levels. The second reason was due to reports, from plant personnel, of compressed air moisture problems negatively affecting the bag life of the dryer baghouses.
Vane motors can run at much higher speeds (2000 rpm and up), but piston motors tend to turn much slower – less than 1000 rpm. For slower speed applications, vane motors are mated with a gear reducer and called a gearmotor. The gearmotor can produce the higher torque and slower speed needed for some applications, but the gear reducer can add some drivetrain loss. While a piston air motor may not be able to replace a vane motor where high speed is needed, it can be a good choice for high torque/low speed applications.
This article discusses some experiences in using cellular connected data loggers to perform a compressed air assessment during a time when travel was restricted. While not ideal, this exercise identified huge savings for this customer.
In the absence of the control system, the air compressors were loading and unloading according to pre-set pressure bands, which forced the system to operate at higher pressures and run inefficient combinations of compressors in order to effectively match air demand. When switched on, irrespective of air demand, the control system was able to control all compressors on a single, tight pressure band and efficiently match output with demand.
The AZEK Company is a producer of durable and low maintenance building materials, and like many manufacturers, it found its compressed air system to be time consuming and expensive to keep maintained. But that changed after the company replaced its outdated and faulty compressed air system with a new design that includes technically advanced air compressors, dryers, receiver tanks – as well as controls to provide better control of the entire system and achieve optimal performance.
When an automotive company added a new 200-horsepower (hp) rotary screw air compressor and accompanying dryer to a satellite building at its Chicago-area assembly plant, it needed a cost-effective way to integrate the equipment into its existing compressed air network. Doing so would allow plant personnel to easily monitor the air compressor’s performance and ensure it operates in harmony with the plant’s centrifugal air compressors. Importantly, it would contribute to efficient and reliable air compressor operation at all times.
One of the challenges with compressed air system design is dealing with periodic large flow demands. Food and beverage manufacturers are among those process industries that often face these events. Adding in the compressed air demands of onsite packaging further adds to the task.
To improve the delivery of compressed air at the plant, which is supplied by low-pressure and high-pressure compressed air systems, the manufacturer took an important first step by using airflow meters to monitor and measure the performance of both systems. Subsequent planning based on actionable data led to a unique compressed air system upgrade that increases the plant’s ability to maintain peak production of high quality glass bottles and containers at all times – while saving \$150,000 per year in energy costs. The project also delivered a payback of less than two years.
Advances in phone technology dramatically improve their function and our experience. More storage, faster speeds, enhanced communication options, bigger and brighter display….and so on. As a result, today’s phones are significantly more powerful – improving our productivity and changing our lives. As for the technology laggards, obsolescence eventually prompts change. Repairing or replacing parts and accessories on the old phones is an increasing challenge. Eventually they have to succumb to technology.
