ISO 14001: was recently updated to ISO 14001: 2015, which introduces a few requirements to a universally beneficial certification. Key benefits of ISO 14001: 2015 include:
Reducing environmental impact
When becoming ISO 14001:2015 certified, Precision Fluidics Division of Parker Hannifin was getting two trash and one recycling pickup each week. The goal was to reverse those numbers. It was achieved in 18 months by training, raising awareness to all employees, increasing recycling bins throughout the facility with signs/labeling, and constant monitoring. Goals of this magnitude take time and planning, but the environmental rewards are immense.
Helping our customers and our team
Precision Fluidics is a great example of an organization set on reducing its environmental impact. A goal was set to improve the durability of product packaging and eliminate landfill waste at a customer location by introducing recyclable materials. A few simple adjustments were made such as using recyclable trays instead of bubble wrap, bubble bags, and foam inside each shipping container. The change resulted in energy savings, trash reduction, and reduction in the weight production needed of each box. The total result was almost 64,000 pieces of foam a year eliminated from landfill, 100% percent recyclable packaging, and a simpler tray packaging system.
Transitioning to a tray system reduced the weight the production team needs to handle when transporting from the production cell to shipping, providing a much-appreciated safety and ergonomic improvement. Another exciting feature of the new packaging is that our product is even more secure during shipment. Following the ISTA (International Safe Transit Association) test procedure, Precision Fluidics validated the new packaging to be an improvement over the non-recycled foam — reducing the risk of shipping damage and increasing the product quality when it's received at our customers' locations.
Reduce, reuse and recycle
Another simple adjustment Precision Fluidics has made is utilizing reusable packaging for component parts from repeat vendors.
Precision Fluidics reuses trays from various vendors when possible (see image left). After the trays are empty, they are shipped back to the vendor and reused. This is a great example of a very simple way to reduce, reuse and recycle.
Precision Fluidics is an ISO 14001: 2015 certified company that has set both large and small goals that have been beneficial to the company as a whole, customers, and best of all, the environment. The above examples show how ambitious yet simple goals can have great impacts. The main objective in ISO-14001: 2015 is having continuous improvement and never being content with what you have achieved.
The first step in becoming ISO 14001:2015 certified is to define your objective. What does your company want to achieve by getting this certification? Make sure you have the support of senior management. Take the time to review any existing processes and systems pertinent to environmental impact. If desired, third-party certifications are available that will conduct audits of your practices against the requirements standards. ISO does not perform certification.

One of the most import medical devices created in the last century is the ventilator. The ventilator is critical for patients who cannot breathe on their own due to medical procedures or long-term respiratory ailments. The significant impact the ventilator has had on the medical industry has made the device an essential piece of emergency care, intensive care, and anesthesia delivery.
Ventilator technology is rapidly advancing, and OEMs (original equipment manufacturers) need component manufacturers to design innovative new parts to meet their demands. Here, we’ll examine what OEMs are looking for when it comes to one of the most crucial components of ventilators — proportional control valves.
From a design standpoint, ventilators can be complex and costly. Using versatile parts that have multiple functions/settings allows OEMs to reduce part complexity — decreasing the number of vendors required as well as making the device easier to manufacture and repair. A proportional control valve that features a wide linear control range makes it possible to have a single ventilator for various desired flow ranges. For instance, different flows are required for a child vs. an adult in respirators or anesthesia delivery.
Other features OEMs are looking for in a proportional valve for the next generation of ventilators are fast response time and consistent flow from cycle to cycle. Fast response is necessary to deliver oxygen in milliseconds when sensors detect a patient trying to breathe. Smooth, consistent flow is very important for the patient’s comfort and safety.
Lastly, OEMs want valves that are compact and energy-efficient. Power and space are limited in portable ventilators. Emergency ventilators need to be light and easy to maneuver. When a hospital loses power, ventilators continue to operate on emergency power and batteries, so any power reductions in the ventilator’s design are desirable.
A one-size-fits-all valve solution
The valve that is meeting all these demands is Parker’s new LM-Pro (Linear Motor Proportional Valve) — an innovative miniature proportional valve that is separating Parker from the competition. The LM-Pro introduces unparalleled flow control capabilities to meet OEM needs. Featuring a linear controllable flow range from 0.5 to 540 slpm for precise flow control, the LM-Pro ensures the accurate and safe delivery of precise gas flow to patients, from neonates to adults. Additionally, this valve offers a pressure capability up to 100PSI (6.9 Bar), and typical power consumption of fewer than 2 watts. It has been tested to well over 100 million cycles. With all these advancements, the LM-Pro is still easily face-mounted/ported into ventilator systems and can be configured with an optional inlet filter to prevent debris from dirty system connections from entering the valve. Parker’s LM-Pro is the only valve that’s meeting OEM demands to make the one-size-fits-all valve solution to achieve the next level of ventilator technology.

The LM-Pro dimension
The LM-Pro is lightweight at 36.6 grams (1.29 oz) and sized for all OEM applications. Read more technical specifications of this product here.
International Standard Organization (ISO) certifications
In addition to the LM-Pro breaking ground with its broad range of controllability, pressure capability, low power consumptions, and validated to over 100 million cycles; this proportional valve has been carefully crafted to comply with some of the most sought-after certifications for medical components. The LM-Pro is certified in two critical ISO standards for anesthesia and respiratory applications: ISO 10993:2010 and ISO 15001:2010. ISO 10993:2010 certification means this valve is biocompatible and does not use materials that can potentially cause irritation when used in breathing circuits. ISO 15001:2010 certification means this proportional valve meets the cleanliness requirements for oxygen circuits. The LM-Pro is compliant with RoHs directive (2002/95/EC) and Reach EC 1907/2006, which means this valve doesn’t use any hazardous materials that can’t be recycled and is composed of registered, evaluated and authorized materials. The LM-Pro is meeting new market needs and complying with the most important medical device certifications.
The ventilator is an essential piece in emergency care, intensive care, and anesthesia delivery, and will continue to be a pivotal part of health care as it adapts to our needs, whether portable, lower power consumption or multiple flow control settings. As ventilator technology advances, OEMs will require innovative products like the LM-Pro miniature proportional valve to stay competitive in the ever-changing medical device market.

A condition monitoring system is concerned with the early detection of failure. Vibration monitoring systems, whether they use traditional techniques based on displacement or acoustic emission sensor techniques, form part of your condition monitoring (CM) tool chest.
Machinery vibration analysis equipment is part of a machine monitoring system that aims to provide months of warning of developing issues before they become bigger problems. This can save your company from serious disruption by avoiding unnecessary downtime and delays. There is also the potential for both on and offline implementation of these systems, subject to capability and level of available technology for the techniques, which makes them perfect for the food and beverage, power generation, marine and offshore industries.
Vibration monitoring equipment uses techniques based on the use of accelerometers, which are well known in the field of CM, and can be classified into three main categories:
VM Vibration Monitoring (ISO 10816): Perfect for maintenance engineers, vibration monitoring ISO 10816 offers an instinctive understanding that a machine is vibrating unusually from the non-rotating parts. Great for small machines, electric motors and pumps and production motors.
VA Vibration Analysis (ISO 13373): A mainstream CM option and essential addition to any other technique used, vibration analysis offers a more sophisticated improvement in signal to noise ratio for repetitive defect signals. This highlights what is internally causing the vibration.
AE Acoustic Emissions (ISO 22096): This technique looks for high-frequency signals from cracks or impact rather than a repetitive movement from vibration. As a passive technique, acoustic emissions can diagnose incipient machinery prior to undertaking a lengthy diagnosis. Highly effective in detecting the very early onset of machinery fault conditions where needed most.
There are many approaches which fall under the umbrella term condition monitoring, each with its own features and areas of excellence. These include machinery vibration monitoring and analysis, and also acoustic emission analysis systems.
Techniques in BLUE = Technologies available from Parker Kittiwake
Parker Kittiwake focuses on techniques such as an acoustic emission system that provides for the greatest protection or longest period of warning for potential damage and eventual failure. While machine vibration monitoring systems can help prevent the worst cases of damage.
