Parker Sporlan's new web-based product selection program, Virtual Engineer, allows the user to size, select and fully configure products for Air Conditioning and Refrigeration applications. Virtual Engineer features quick selection of single or multiple components by template. An innovative dashboard and project system make saving, editing, and sharing projects easy. 

Virtual Engineer replaces Parker Sporlan’s legacy Selection Program. The legacy Selection Program was originally created to perform distributor calculations for internal purposes. Over the years, its use expanded to include many of the products Parker Sporlan offers and became an industry standard tool for selecting products in HVACR applications. 

By using Virtual Engineer, OEMs, Wholesalers, and Contractors can select the latest Parker Sporlan products with the most up-to-date refrigerants available on the market today. Users can select and size easily while out on the job site, in the equipment room or from their office. Parker Sporlan is committed to serving the HVACR industry with new and updated innovative tools to help users get the job done quickly and efficiently.

Virtual Engineer highlights 17 product areas with a basic template layout.

Product areas:

  • Distributors

  • Expansion Valves

  • Solenoid Valves – Discharge, Suction, Liquid

  • Catch-Alls® – Liquid, Suction          

  • Suction Filters

  • Discharge Bypass Valves

  • Evaporator Pressure Regulators

  • Discharge MTW Valves

  • Head Pressure Control Valves

  • Differential Pressure Regulators

  • Temperature Responsive Valves

  • 3-Way Hot Gas Defrost Valves

  • Condenser Split Solenoid Valves

  • 3-Way Heat Reclaim Valves

  • Secondary Coolant Valves

  • Liquid, Discharge and Suction Line Sizing

  • Flash Gas Bypass and Gas Cooler Valves


Getting started - Background and the basics

 With the use of an interactive template, all product areas are represented on the Dashboard when the user accesses the login page. The user can toggle from part to part from within the different categories, then is prompted to enter specific information when the part is chosen. Once a part is chosen, the Sizing and Configuration tools for each product appears. This feature is particularly valuable in systems such as cooling loops in which the optimal sizing and selection path is not intuitive. First-time users can now complete sizing and selection with minimal assistance.

Virtual Engineer allows refrigerant and product updates to become available as they are released. The web-based aspect of it ensures users are working with the latest version of the program. The HTML5 interface makes it scalable to the screen size being used. NIST Refrprop 10.0 is used for the refrigerant properties.

Popular system features from the previous Selection Program such as line sizing and thermodynamic reports have been carried over to Virtual Engineer. Thermodynamic reports have been expanded to include Pressure-Enthalpy, Pressure-Temperature and Enthalpy-Temperature graphs.

“We are excited about several new tools in the Virtual Engineer package, including the ability to size electric valves and mechanical valves in the same tool allowing for side-by-side loading analysis. The new software also allows for sizing of a wider range of electric valves including the Modulating 3-Way Valves, electric head pressure control valves, and Transcritical CO2 products. The new tools build on Parker Sporlan’s legacy of supporting the HVACR industry and providing new, innovative tools that help users get the job done.”

Why is Outgassing Critical in Optics and Electronics Applications? - GettyImages-963423914-electronic-board-checked-using-an-electron-microscope300x200 - Parker O-Ring & Engineered Seals DivisionFor some applications, a critical component of selecting a seal material is a phenomenon known as “outgassing”. However, even within the elastomer community, outgassing is not something that is commonly considered. Which begs the questions: what is outgassing and why is it important? Outgassing is usually most relevant in vacuum applications, where the vacuum causes the elastomer to release constituent material. The constituent material could include water vapor, plasticizers, oils, byproducts of the cure reaction, or other additives used in the seal material. Outgassing becomes a problem if a thin film of those chemicals condenses and is deposited on nearby surfaces. Such a film poses major challenges in highly sensitive applications, such as optics or electronics, where cleanliness is of utmost importance. A seal material with low outgassing  is essential because it shows the seal material does not emit volatile constituents under vacuum conditions.

Weight loss of compounds in vacuum

Outgassing is most often characterized by weight loss of the seal material. The ASTM test method E595 is one way to quantify outgassing by measuring Total Mass Loss (TML %), Collected Volatile Condensable Materials (CVCM %) and a reported value for Water Vapor Regain (WVR %).  Measurements are taken following a 24 hour exposure to vacuum of 5x10-5 torr at a temperature of 257°F.

Why is Outgassing Critical in Optics and Electronics Applications? - Black O-rings 300x200 - Parker O-Ring & Engineered Seals DivisionTaken together, these three parameters tell a complete story. The TML is reported as the percent of the specimen’s initial weight that is lost during the test; under standard criteria, the result must be less than 1.00% mass loss. Obviously, minimizing TML is a good thing, but it is not the only important factor. Collected volatile condensable material (CVCM) is the amount of outgassed matter from a specimen that condenses onto a collector during the maintained time and temperature. CVCM is of particular concern because any material that readily condenses in the test is likely to condense on and contaminate nearby surfaces during use. To pass the standard CVCM requirement, the amount collected relative to the initial mass of the specimen must be less than 0.10%. The final measurement, WVR, is the mass of the water vapor absorbed by the specimen after a 24-hour stabilization at 23°C in a 50% relative humidity atmosphere. There is seldom a pass/fail limit for WVR; instead this result is merely reported. In many applications, the small amount of water vapor lost by a seal may not be of concern, particularly if the application already includes a means of controlling moisture. Further, any WVR is presumed to be equal to the portion of original TML that was water vapor. The difference between TML and WVR is therefore presumed to be volatile organic material that has evaporated out of the material (only some of which condenses in the CVCM test), so minimizing the difference between TML and WVR is also of considerable importance.

To illustrate, we can look at the most recent outgassing data completed on a few popular low temperature fluorocarbon materials. Table 1 contains the results from a 3rd party laboratory to measure the outgassing properties of VM125-75 and VX065-75. Both had undetectable amounts of CVCM and very small differences between TML and WVR.  VX065-75 in particular displayed remarkably little outgassing as well as a low WVR.

There are a few additional resources detailing seal materials that are known for having low weight loss. The O-Ring Handbook ORD 5700, Table 3-19 (page 65 of the pdf), has a few legacy materials with weight loss percent after a two-week exposure to 1 x 10-6 torr vacuum level, at room temperature. Additionally, non-Parker resources such as the NASA website contain an interesting summary of a much broader range of materials.

What is ISO14001:2015 - Recycle - Parker Precision FluidicsISO 14001 is recognized as the international standard for environmental management systems and provides organizations/businesses with criteria to follow, which will identify, control, and reduce their environmental impact. Becoming ISO 14001 certified has numerous benefits to businesses, sectors, and activities large or small. ISO 14001 is a voluntary standard that hundreds of thousands of companies worldwide have chosen to become certified in, uniting them in a global goal to reduce the environmental impacts created by companies and businesses, to preserve the natural Earth for future generations.


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:

  • Improved environmental management - Reduce the resources your business consumes and improve efficiency. 
  • Legal compliance - Understand regulatory requirements impact on your business and customers.
  • Reduce operating cost - Save money through efficiencies in energy and water usage.
  • Improved stakeholder relationships - certifications demonstrated to potential customers that you are proactive and responsible.
  • Proven business credentials - verification proves and gives recognition to achievements.
  • Increase business - business often requires certification as a condition to supply.


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

What is ISO14001:2015 - tray - Parker Precision Fluidics

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

What is ISO14001:2015 - trays- Parker Precision FluidicsAnother 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. 


Becoming certified

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.
