What G2 Tech Pty Ltd does

G2 Tech Pty Ltd is an Australian proprietary limited company headquartered in Carrum Downs, Victoria, that designs, manufactures, and maintains commercial solar thermal, hot water, warm water, and water treatment systems for Australian and international clients. Its core product line centres on the G2 Aeris warm water delivery system family, which combines centralized thermostatic mixing valves, dual ring main pump sets, and proprietary copper-silver (Cu-Ag) ionisation technology to provide residual disinfection against legionella in aged care and healthcare facilities. Supporting offerings include a +gas series of gas-fired commercial calorifiers (315L to 800L storage), commercial solar thermal pre-heat systems using evacuated tube technology, dual ring main circulators with BMS integration, water filtration packages, flue design, and a Dairy Hot Water Solutions product line for the food and beverage sector.

The company generates revenue through four streams: hardware sales of pre-packaged and custom-designed hot water and warm water systems, professional engineering and design services (delivered in AutoCAD or SolidWorks), preventative maintenance agreements managed via a Computerized Maintenance Management System (CMMS), and turnkey project delivery. Pricing is quote-based and tailored to project specifications, with on-site commissioning (Comm Assist) complimentary for orders above AUD 25,000. Go-to-market is direct enterprise field sales, supported by a company website, a toll-free phone line (1300 428 111), and reputation-driven engagement through tender processes in aged care, hospitality, education, healthcare, and commercial building sectors.

G2 Tech serves aged care facilities (its primary vertical), hospitals, universities, hotels, commercial and industrial buildings, and wineries/abattoirs, with a notable customer base including Arcare, Blue Cross, Mecwacare, Nazareth House, St Vincent Private Hospital, Australian Unity, the University of Melbourne, La Trobe University, Monash University, Accor Asia Pacific, Mercure, the Great Southern Hotel, and Viva Energy. The firm operates with 1-10 employees and is privately held with no disclosed external investors, making it a tightly scoped specialist engineering company rather than a scaling platform.
