When it comes to hoses and cold weather performance, force to flex is not as important as actual hose construction. In harsh winter temperatures, hose construction materials can be a major contributor to hose failure. Over time, cold temperatures and UV rays dry out the core and jacket of a hose. This embrittlement of materials results in cracks. Cold sluggish fluid or low temperature fluids not compatible with the core materials can also add stress and cause damage.
Parker engineers have been working closely with machine and vehicle designers for more than 30 years on the selection of optimal hoses. The added stress of colder environments, led them to design the new, low-temperature hydraulic hoses which operate in temperatures as low as -70°F/-57°C with pressures operating up to 5,000 psi (345 bar).
This new technology for low-temperature hydraulic systems has proven itself in a variety of different low and high-pressure applications, especially forklifts and aerial lift equipment or used in commercial freezers in harsh winter conditions. Applications range from low pressure fluid transfer, over-the-sheave, and steering lines to high-pressure hydraulics.
Parker low temperature thermoplastic hoses are built with a proprietary blend of materials specifically formulated to withstand repetitive flexing in cold temperatures. The 563LT and 594LT offer the same abrasion resistance as Parker's standard hose but decrease component downtime in low temperatures. The ability of these hydraulic hoses to perform repetitive flexing in a cold environment opens a new range of possibilities for the industry while increasing product life. For the customer, excelling in cold climates means reduced change outs, reduced warranty maintenance and replacement costs.
Each hose is reinforced with either synthetic fibers, steel wire, or a layer of each, which enables assemblies to handle up to 5,000 psi (345 bar) working pressure (depending on hose selection). Available core tube options have a low coefficient of friction while maintaining excellent flexibility and a premier, abrasion resistant cover. This maximizes efficiencies and minimizes pressure losses to ensure long service life.
Temperature deformation of the product does not affect the assembly’s chemical compatibility, technical performance or functionality. In addition, hose covers are durable and insensitive to UV or ozone exposure and thus, resistant to environmental stress.

Reliable cooling is a decisive factor for production, particularly in the marine industry. It is responsible for ensuring adequate temperatures in the turbine, the electronics racks and on the tool, or the machine, itself. The entire production and product life cycle of elements and machines are dependent on the efficiency of the cooling process and how it ensures ideal operating temperatures.
Parker has a broad program of thermal management components. It stands out thanks to its efficient interplay which is essential for ensuring that cooling circuits work reliably on a permanent basis. Each individual product stands for reliable functionality, durability, high material quality and compact design.Parker quick-action couplings are easy and fast to assemble
Quick-action couplings that can be used to connect cooling elements and cables are well suited to the thermal management field. Parker's RNS Series systems for block and panel installation expand the possibilities of design freedom for planning and installation. The series was initially developed for control cabinets to allow fast and reliable coupling and locking of the cooling circuits to the racks.
It has several benefits:
Another benefit of Parker's quick connection couplings is the variety of materials available. NSA Couplings, for instance, are made of aluminium and correspond with the trend towards lightweight construction. In addition, components made of nickel-plated brass or stainless steel are corrosion-free with a wide range of liquids, while offering consistent quality and long service life, just like the other couplings. Thanks to the different sizes available (3, 6, 9, 12, 16, 19 and 25 mm), couplings can be adapted optimally to the specific cooling circuit. When used in transportation systems, the couplings prove their resistance to vibration and torsional movements.Silicone hose minimizes maintenance costs and assembly time
The 6722 Series Silicone hose is an important system element for the heating and cooling applications as they allow to minimize maintenance cost and time and maximize the performance of the system.
The extruded hose meets SAE J20 R3 Class A specification and can be installed as thermal management solution wherever there is a cooling/heating circuit to run efficiently. The low permeation material is suitable for a wide range of coolant fluids and withstands ozone and UV attack more efficaciously than traditional solutions. The series is not only chemical and oxidation resistant but also extremely stable at elevated operating temperatures in engine compartments starting from –54°C to achieve +177°C. It maintains flexibility and elasticity over time. This reduces the risk to crack, harden, or become dry rotted and increases the possibility of installation in narrow and compact spaces, tight envelopes and around an obstruction. Additionally, it offers good ability to dampen sounds and vibrations keeping a quiet and stable profile. All these benefits contribute to an extended service life reducing costs of maintenance, downtime, warranty and logistics while sustaining the performance of circuits and equipment over the long haul.
There is no better choice for today’s trend where there are applications surpassing the temperature capabilities of other rubber solutions on the market. Silicone is the ultimate choice for extreme temperature applications and when flexibility over the lifetime is requested.Total system solution
The wide Parker product range for Thermal Management is enlarged by its extensive portfolio of push-to-connect fittings as an alternative to metal screw-on, clip-on and barbed connection technologies. The productivity is increased thanks to quick assembly (connection without tools; no need to weld, glue or crimp).
Based on its broad product range, Parker develops modular systems in close collaboration with its customers. In addition to individual products, the company also offers ready-to-install systems from coupling to screw fitting, hose or distributor. The benefit for the customers is that they can rely on the supplier’s decades of experience and they can save valuable assembly time thanks to the delivery of complete systems blocks, which in turn greatly simplifies the spare parts stocking process.

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.
