Industrial Utility Efficiency    


When users consider adding an oil free air compressor to their facility, there are several factors that should go into the decision to ensure it is the right equipment for the user’s operation. Some considerations and factors can include why to choose oil free to begin with; how to properly select and size the compressor; how to adjust sizing for different cooling water conditions or different ambient temperatures; and what it will take to maintain the compressor throughout its lifespan. To lay a foundation, it is important to first understand why oil free air is important, how compressed air is used and what options are on the market.

Air Compressors

Properly sizing a compressed air system can help determine if your facility has enough air to adequately supply your production equipment. Designing a cost effective system that minimizes any interruptions to productivity requires thoughtful planning and design. Typically, the desired outcomes of such a system focus on stable pressure and efficient operation, though it is important to note that each of these elements requires a unique solution. This article will provide guidance in proper selection considerations and suggest when a centrifugal air compressor may be ideal for your needs.

Air Treatment

This article is for you if your company is purchasing nitrogen gas at 99.999% purity and you’re not sure why.  While there are many applications which do require nitrogen gas concentrated to 99.999%, they are significantly outweighed by the applications that don’t. Rather than relying on a delivery of bulk liquid or pressurized cylinders, many nitrogen users are choosing to produce a custom supply of nitrogen within their facility, and they are doing it at a fraction of the cost. Over the past decade we’ve seen a mass industry shift from delivered nitrogen supply, to nitrogen generation.


The plant upgrades, in combination with a progressive management strategy, allows the plant to consume less energy and reduce its reliance on outside contractors for biosolids removal, resulting in total operational savings of approximately $60,000 per year.  The plant is also positioned to efficiently manage the area’s wastewater for decades to come.

Compressor Controls

A large chemical plant in Celje, Slovenia, planned to retrofit a kiln used to produce titanium dioxide. To make space for the new equipment related to the retrofit, the plant needed to relocate its high-pressure compressed air system feeding an adjacent pressing process used to dry the material before firing it in the kiln. However, a comprehensive compressed air audit using cloud-based software showed the plant did not need to relocate the system.


Micro-aerosolized droplets are how many members of the microbial world become cross-contaminants via the air mode of transmission.  Food borne viral pathogen Hepatitis A and the ubiquitous Norwalk are very often transported via micro- aerosols. It is well known that many viral or bacterial pathogens or spoilers are transmitted via respiratory bursts [coughs/ sneezes] from people or air handling system, condensate, and splash back from floors. Strict cGMPs  can limit  and control transmission in terms of personal & environmental  hygiene.


Electricity and compressed air play an important role in the thermal and kinetic processes for everything from mixing and extruding the ingredients, deep-freezing to -13°F (-25°C), dipping into various chocolate coatings through to final packaging. Energy efficiency is therefore right at the top of Unilever’s list of priorities. As part of the Unilever Sustainable Living Plan, this global corporation has succeeded in saving more than $186 million in energy costs from efficiency improvements in production alone since 2008.


It’s one thing to move materials during the production process, but when it’s a finished product on the packaging line, choosing the right material handling system is essential. Getting it wrong results in squandered production time when product loss occurs, and wasted raw materials.

Cooling Systems

With efficient heat exchange an important requirement in the design of an HVAC system, the type of cooling tower you specify to support your project’s unique cooling goals requires careful consideration. After determining the process parameters required for your application – tonnage, range, and approach – cooling tower capabilities can be analyzed.
BEKO Technologies’ business strategy is rooted in ingenuity, dating to the very beginning when it pioneered the use of zero air loss condensate drains with the introduction of the BEKOMAT® condensate drain. The company, which was far ahead of the curve at the time when it created the BEKOMAT, developed the technology to help users save energy at a time when energy wasn’t a priority for most.
In this article we will discuss how to achieve actual oil-free air from your air compressor, no matter what type of air compressor it is. Air compressors of all designs turn mechanical power into pneumatic power by successively concentrating air across compression stages. A rotary screw air compressor, for example, utilizes rotating helical screws to drive air forward, increasing its pressure by reducing the volume of space the air mass takes up. Mechanical compression of this nature takes quite the force and energy to accomplish, which equates to heat generation and physical wear inside of the compressor. 
Reciprocating/piston air compressors have many moving parts and regular maintenance is an essential practice.  This ensures all compressor components function at peak efficiency as well as for preventing wear that can ultimately lead to premature failure. The following tips can serve as a guide for safe, reliable, and economical reciprocating compressor operation and maintenance.
Batch tracing is a critical process for any business that is interested in quality management. The importance of this process goes well beyond the manufacturing stages of a product. As it relates to air compressor lubricants, the ability to trace a product throughout its useful life, has a direct impact on the distribution and servicing organizations that use these products in the field. Service contractors, distributors, resellers, and even online wholesalers all have a responsibility to both protect themselves from liability, as well as their customers, by ensuring that traceability systems are in place and maintained down to the end user.
Reciprocating air compressors are designed for variable up and down duty cycle applications as the full power of the compressor is available when needed. When demand stops, a reciprocating compressor shuts off automatically to reduce consumption of power. In selected cases where the high demand for air is short term, a tank mounted system provides air flow bursts that exceed the capacity of the compressor by using stored up compressed air from the tank.
The Wonderful Pistachios and Almonds campus in Lost Hills, California is a manufacturing facility that processes and packages pistachios and almonds for the consumer market. Food processing requires extensive use of compressed air to control multiple applications ranging from actuators, valves, optical sorters, packaging equipment and plant maintenance operations. The campus has its peak season during harvest in late August/early September, but processing and packaging operations take place year-round.
For decades, a major meat processor and packaging operation in Northern England did what many growing companies do when more compressed air is needed to meet demand: added another air compressor and then another air compressor and so on. Yet the company decided the strategy of adding equipment had run its course, especially given a positive outlook for continued growth and the need to resolve nagging issues with system downtime and compressed air quality.
One of the most satisfying parts of being a compressed air system auditor is resolving compressed air system reliability issues. This article exposes a seldom, if ever, mentioned problem that can occur when air dryers are dedicated to air compressors. It examines a real-world application and discusses the action taken to remedy the situation.
Moisture in compressed air is almost never a good thing. It can damage a compressed air system by causing corrosion, rust and scale buildup. It can damage downstream equipment with these moisture byproducts or with the moisture itself. It can negatively affect processes and products that require dry compressed air.
Industrial operations and manufacturers using pneumatics have access to more Industrial Internet of Things (IIoT) technology than ever before, from position sensors on cylinders to system flow sensors and edge gateways that operate independently from the machine controller with globally accepted communication protocols.
