Updated PCM testing specifications are now available on RAL website

Ben Welter - Monday, May 28, 2018

A revised version of a document outlining the RAL Quality Association PCM’s quality testing program has been approved by the association's governing body and is now available on the association's website.

RAL quality mark“Quality and Testing Specifications for Phase Change Materials,” also known as RAL-GZ 896, sets out the general principles for PCM. The document defines PCM, PCM composites, PCM objects and PCM systems; establishes performance requirements; and outlines the nature and scope of monitoring measures.

Improvements to RAL-GZ 896 include:

• Clearer structure and wording. 

• Heat flow meter measurements are now permissible. This will make measuring larger PCM products much easier.

• Reduced testing frequency during cycling. The prior edition required testing the quality criteria at fixed intervals during cycling. The new edition recommends testing at intervals during cycling (to reduce the risk that cycling is continued until the end despite the sample has already failed) and the intervals are wider. These changes are designed to reduce the cost of testing.

• Segregation, an important criterion for salt hydrates especially, was approved as an additional quality requirement.

• Better explanation of monitoring.

“The now published document is a huge improvement” said Stefan Thomann, the association's managing director. “Over a period of two years, an expert task group added crucial requirements, new measurement methods and better explanation and guidance. The RAL Quality Mark as an independent proof of outstanding quality has become even more meaningful now.”

Axiotherm joins RAL Quality Association PCM

Ben Welter - Thursday, March 01, 2018

Axiotherm GmbH of Germany has joined the RAL Quality Association PCM, a European-based organization established in 2004 to develop standards for the phase change material industry.

Axiotherm, a subsidiary of ESDA Technologie GmbH, specializes in developing macro-encapsulation of phase change materials for various applications. The company's HeatSel capsule, for example, is designed to increase the capacity of water-based heat and cold storage systems.

Dirk Buttner at Swiss TES symposium, January 2018Dirk Büttner, Axiotherm's chief research officer, said the European Commission recently recognized HeatSel's market potential.

"Out of 135 applications in the Horizon 2020 SME's energy category, the Hi-ThermCap project proposal was rated with the highest score and thus ranks first among the most innovative ideas in Europe," said Büttner, right. "Within the scope of the project Axiotherm is now also striving for validation by an external testing of their products performed by one of the association’s monitoring institutes, ZAE or ISE."

Croda International, which is working with Axiotherm on thermal energy storage applications, is also a member of the association. Other members are Microtek Laboratories, Rubitherm, EMCO, va-Q-tec, PCM Technology, Global Energy Systems Europe, Sasol, Sunamp Ltd., Pluss Advanced Technologies and Entropy Solutions.

The association held its semiannual meeting in Düsseldorf, Germany, on Thursday. Crystal Air PCM Ltd. was invited as a guest but had to cancel because of severe weather in Ireland. The company will be invited to make a presentation at RAL's next meeting, scheduled for Nov. 15, 2018, in Düsseldorf.

• Nantucket, Mass., has approved the installation of an Ice Bear thermal storage and air-conditioning unit in a building owned by the town. Last summer, Genbright won a $1.5 million grant from the state to install the units in more than 200 Nantucket homes, with the goal of reducing peak energy demand and staving off the need for a third undersea power cable for the island. But some residents voiced skepticism about the technology, prompting the town board to approve the test installation.

• Shippers have found that cocoa butter can be hard to contain on long ocean voyages. There have been reports of the material leaking out of containers as it changes phase, clogging bilges and generally making a mess. The Cargo Incident Notification System, established in 2011 to share information on all cargo-related incidents, has issued guidelines that recommend the material be shipped in refrigerated containers, particularly when passing through hot climate zones. 

New map shows notable PCM building projects around the world

Ben Welter - Tuesday, February 06, 2018

Phase change materials have been improving energy efficiency in homes, schools, office buildings and cold-storage warehouses for more than a decade. Now, for the first time, makers of PCM products and systems can submit their signature projects for inclusion in a Google-based map. 

RAL PCM mapThe new map is maintained by the RAL Quality Association PCM, a European-based organization established in 2004 to develop standards for the PCM industry. Sunamp Ltd., Pluss Advanced Technologies, PCM Technology and other association members are among the early contributors to the map. PCM makers around the world are invited to submit their projects.

Stefan Thomann, the association’s managing director, explained the map's purpose.

"PCM products and systems can be used to efficiently regulate temperature and store energy in buildings," he said. "But the players who are active in this area frequently encounter the prejudice that it is a new technology that is still in its infancy. Well, it isn't. It is mature and fully developed and has proven its effectiveness numerous times.

"The map shows successful PCM installations around the world to make that point. It is only a start at this point in time, showing only a fraction of the installations, but it will be updated and extended continuously."

The map now lists information on more than 60 PCM installations. Some of the project descriptions are terse; others offer quite a bit of detail. The most useful listings include the building name, building type, project description, location, PCM application type, manufacturer name, product name, year of installation and a website where more information can be found. 

Listings should be sent to s.thomann@pcm-ral.de.

RAL Quality Association PCM approves updated quality and testing specifications

Ben Welter - Thursday, December 14, 2017

Members of the RAL Quality Association PCM have unanimously approved revised versions of two documents governing the association’s quality testing program.

The association, formed in 2004, promotes the use of high-quality phase change material and oversees independent testing of PCMs. Members include Croda, va-Q-tec, Pluss Advanced Technologies and Entropy Solutions. Members and non-members alike can submit their products to the association for independent testing and earn the RAL Quality Mark.

RAL PCM quality markThe first document, “Quality and Testing Specifications for Phase Change Materials,” also known as RAL-GZ 896, sets out the general principles for PCM. The document defines PCM, PCM composites, PCM objects and PCM systems; establishes performance requirements; and outlines the nature and scope of monitoring measures.

Improvements to RAL-GZ 896 include:

Clearer structure and wording, less text. The prior edition was judged to be strongly fragmented, hard to read and too long. At the same time some definitions, especially those in the glossary, required clarification.

Heat flow meter measurements are now permissible. This will make measuring larger PCM products much easier.

Reduced testing frequency during cycling. The prior edition required testing the quality criteria at fixed intervals during cycling. The new edition recommends testing at intervals during cycling (to reduce the risk that cycling is continued until the end despite the sample has already failed) and the intervals are wider. These changes are designed to reduce the cost of testing.

Including segregation. Segregation is an important criterion for salt hydrates especially and was included as additional quality requirement.

Better explanation of monitoring.

The second document provides detailed provisions and references to the certification of PCM, PCM composites, PCM objects and PCM systems. Improvements to this document include more detailed descriptions of measuring methods and guidance on which methods are appropriate for different types of PCM.

The revised documents will be submitted to the German RAL Institute for Quality Assurance and Certification, the PCM association’s governing body, for final review and approval. The revised documents are expected to take effect in early spring.

Samit Jain, managing director of Pluss Advanced Technologies, was also attending his first RAL meeting. Jain, right, presented an overview of Pluss R&D efforts and its PCM product line, which is focused on addressing four challenges: vaccine waste, food spoilage, neonatal deaths and energy inefficiency in buildings. 

Other member organizations attending the meeting in Dusseldorf were Croda, va-Q-tec AG, Rubitherm, ZAE Bayern, Fraunhofer ISE, Sasol Germany GmbH, Sunamp Ltd., EMCO, PCM Technology and Entropy Solutions. Discussion topics included RAL-GZ 896 quality and testing specifications; registration of the new RAL quality mark; efforts to integrate PCM in the German Energy Saving Ordinance; ISSO publication 111 PCM in Netherlands; and the new Phase Change Materials Industry Association of North America.

As the meeting drew to a close, Prof. Bernd Boiting, chairman of the quality association, thanked BASF's Marco Schmidt for his contributions. As Micronal's head of business management at BASF, Schmidt played a key role in many RAL initiatives, including the development of a Google map that will showcase PCM building projects around the world.

RAL's next meeting is scheduled for March 1, 2018, in Dusseldorf. 

PCM briefing: Managing heat in low-orbit satellites; Expert Forum on VDI 2164 canceled

Ben Welter - Tuesday, May 30, 2017

Roccor LLC of Longmont, Colo., is using phase change material in a device designed to manage internal heat in low-orbit satellites. “We have one product with paraffin wax inside a flat structure. When the spacecraft is hot, it dumps heat into that paraffin wax and turns that into a liquid — basically a store of energy,” Chris Pearson, Roccor’s vice president of space programs, said in an interview with Via Satellite. The heat is later released into the satellite to keep temperatures stable.
