Our Mission is Advancing Performance through Expert Rotating Equipment Solutions
Established in 2013 by industry veteran Arthur Stack, AJSS combines decades of OEM expertise with a passion for knowledge sharing to reduce technical risk, lower costs, and drive operational excellence across Australasia’s most critical industries.
Specialists in field services, training and engineering solutions for critical rotating equipment since 2013
Founded in 2013, AJSS was established to improve the delivery of technical and business solutions for customers operating critical rotating equipment. Built on experience across OEMs, equipment operators, field service, engineering, and training, AJSS brings together a team focused on practical problem-solving, knowledge sharing, and condition-based maintenance.
Today, AJSS supports the oil and gas, power generation, and mining industries by helping customers improve equipment performance, reduce technical and commercial risk, and achieve cost-effective outcomes. The company provides project management, detailed design, technical auditing, field support, and technical training, while continuing to invest in practical innovation and challenge conventional approaches to solve complex client problems.
Redefining Industrial Excellence
2013
The Founding of AJSS
Arthur Stack decided to take early retirement from Solar Turbines and formed AJSS. The company was established with the encouragement of his wife, Elaine, to provide specialised technical and business solutions for rotating equipment that clients were not receiving from original equipment manufacturers (OEMs).
2015
Regional Partnerships and Global Contracts
Expanding the footprint into Papua New Guinea and beyond. In early 2015, AJSS formed a strategic partnership with GMT Automation, a national company in Port Moresby, PNG. Later that same year, the company reached a major milestone by being awarded its first long-term service contract outside of Australia.
2016
European Alliances and Asian Educational Reach
Broadening technical representation and training capabilities. In January, AJSS signed a representation agreement with Airpack Netherlands to package European compressors and nitrogen generators. The company also expanded its educational influence by hosting a forum in Myanmar in July, which led to the awarding of its first Asian training contract in October 2016.
2017
Infrastructure and Product Innovation
Establishing a dedicated training hub and bespoke equipment solutions. AJSS opened its new interactive training facility at the Cheltenham office to provide hands-on learning for students and technicians. This year also marked the launch of their first product, a specialised transportation and storage container, with plans to offer various models for lease.
2021
Challenging the Norms in Engineering
Proving technical possibilities through critical problem-solving. In December 2021, the team successfully supported a customer by swapping dry gas seals between compressors to avoid millions in lost revenue—a move the OEM claimed was not possible. This event solidified the company’s reputation for "challenging the norms" to find cost-effective solutions.
2022
The Emergence of Stacked Learning
Transforming technical education through immersive digital solutions. Building on over 400 combined years of engineering experience, AJSS launched Stacked Learning. This new entity focused on bespoke courses, face-to-face training, and immersive digital content—moving beyond "digital slide decks" to utilise VR, AR, and gamification based on the "Cone of Learning" philosophy.
2023
A Decade of Excellence and Further Expansion
Celebrating ten years with a new headquarters and global ventures. AJSS celebrated its 10th anniversary, marking a decade of success driven by family support, employee dedication, and customer trust. Significant developments this year included the purchase of a new office and training centre in Perth and the transition of the training arm, Stacked Learning, into a Singapore-based company to achieve a global reach.
2025
The Acquisition of GTS and Clayton Expansion
Strengthening parts supply and establishing a new Melbourne headquarters. In December 2025, AJSS announced the acquisition of Gas Turbine Services (GTS), effective January 5th, 2026. This acquisition significantly broadens AJSS's support for the Frame & Industrial Gas Turbine range (Frames 3, 5, 6, and 9). In alignment with this growth, the company established a new Melbourne headquarters in Clayton, complemented by a dedicated warehouse in Perth for storage and dispatch.

STREAT
As a partner of this social enterprise, AJSS helps provide training and employment opportunities in the hospitality industry for young people experiencing or at risk of homelessness.
Cancer Council
As a leading foundation in the fight against cancer, they fund research and provide crucial support to those affected. In 2023, Arthur personally completed "The Longest Day" golf marathon, playing four rounds in a single day to raise $17,000 for cancer research.
RCD Foundation
Supporting paediatric brain cancer research in memory of Robert Connor Dawes, AJSS participates in initiatives like Connor’s Run to fund care and development projects.

Charity Skydive
To support local communities, the team parachuted from 14,000 feet over St Kilda Bay, raising approximately $14,000. We managed these funds to ensure a "multiplied impact," purchasing eggs from local farmers and meat from butchers to then distribute to other organisations and firemen.
Daylesford Cinema
Named in honour of John Egan, the Irish pioneer credited as the first to discover gold in the Daylesford district in 1851 and reputedly the second in all of Victoria, Phoenix at The Rex carries on the spirit of a man who helped build a community from the ground up. AJSS is proud to support this cultural landmark, where Daylesford's rich history and vibrant present continue to meet.

Through research, advocacy, and support services, they work tirelessly on behalf of Australians living with this life-limiting condition and their families. AJSS is proud to support their mission.
Celebrating Ten Years of Technical Innovation
The Foundation of Success Reflecting on the past ten years, Managing Director Arthur Stack recalls the early days in 2013 when the company was merely a "watching brief" and a conversation with his wife, Elaine, who inspired him to take the leap. What began with a small, dedicated team has flourished into a business that now supports 31 major customers across the oil and gas, power generation, and mining sectors. Our success is built upon a foundation of family support, loyal partners, and a team of experts who treat one another like family.
