Climatech Group

What Climatech Group does

Climatech Group, founded in 1989, is one of Australia's largest Tier 1 mechanical services (HVAC) contractors, headquartered in Kogarah (Sydney) with offices in Canberra (ACT) and Murarrie (Brisbane), operating across Australia and New Zealand through its subsidiary Sedatech. The company delivers comprehensive design and construction solutions spanning commercial, data centre, defence, healthcare, retail, education, correctional, government, and infrastructure sectors, with individual project values ranging from $300K to $85M (notably Quay Quarter Tower at $85M for Multiplex, Wynyard Place at $65M, and 6 & 8 Parramatta Square at $62.5M for Walker Corporation). Its technical capabilities rest on four pillars: BIM-led project coordination (3D Revit modelling and simulation), NABERS and Green Star credentialed energy-efficient design, cogeneration/trigeneration systems (including a 3.6 MW system delivered for Westfield's $1.2B CBD precinct redevelopments), and prefabrication and modularisation that shifts high-risk work offsite. The group also operates industrial refrigeration through Tri Tech Refrigeration Australia (acquired 1 July 2022), and 24/7 service and commissioning through Seda Services.

The business model is B2B mechanical contracting: project-based, lump-sum tenders for design and construction, plus ongoing service and maintenance revenue. Go-to-market is enterprise field sales via competitive tendering and early-stage design partnerships with Tier 1, 2, and 3 builders (Multiplex, Mirvac, Walker, Lendlease, John Holland, CPB Contractors) and direct relationships with major asset owners and hyperscalers (Scentre/Westfield, QIC, AMP Capital, AWS, Equinix, AirTrunk, Department of Defence). Marketing is dominated by project portfolio, sector credentials (NABERS, Green Star, Defence clearances), and repeat referrals rather than broad digital campaigns. Pricing is not publicly disclosed; quotes are issued per project based on scope and complexity.

On 30 January 2025, shareholders sold a 70% majority stake to Japanese listed multinational Sojitz Corporation through its Australian subsidiary Ellis Air Group, combining Climatech with Ellis Air's ~450-employee Victorian, Queensland, and New Zealand operation to form a leading ANZ HVAC and Refrigeration provider. Existing management (CEO Joel De Stoop, Managing Director Marc De Stoop, GM & Director Nahi Beaini, Director QLD & NZ Ryan De Stoop, Director & Financial Controller Emmie Yang) continues to run operations, with Climatech, Sedatech, Seda Services, and Tritech Refrigeration retained as standalone brands. The company is now pursuing international expansion, evidenced by the December 2025 MOU with FAS Energy & Infrastructure for advanced district cooling solutions in the Kingdom of Saudi Arabia, anchored on King Fahd International Airport in Dammam under Saudi Vision 2030.

Broad incumbents

• EMCOR Group: Large US-listed mechanical and electrical services contractor with global operations delivering HVAC, building automation, and energy services — comparable Tier 1 mechanical contractor model, though at materially larger scale and geographic spread.
• CPB Contractors: Major Australian tier-1 contractor (CIMIC Group subsidiary) executing large-scale infrastructure, commercial and defence projects — broader incumbent that is also a Climatech customer, providing alternative in-scope mechanical capability to general contractors.
• Comfort Systems USA: US-listed national mechanical services contractor serving commercial, industrial, and data centre customers with HVAC, plumbing, and building automation — directly comparable business model and hyperscale data centre exposure, though US-focused.
• Downer Group: Large Australian listed infrastructure services group with HVAC, electrical, and facilities maintenance capabilities across transport, utilities, and commercial — broader incumbent with overlapping mechanical services portfolio and scale advantages.
• Honeywell Building Technologies: Global building automation and HVAC controls provider (Honeywell division) — broader incumbent whose products complement or compete with mechanical contracting scopes; relevant for the building controls portion of Climatech's portfolio.

Others

• Lendlease: Australian-headquartered global real estate and construction group — also a Climatech customer (e.g., Gosford Hospital $32M); adjacent peer at the construction-firm tier that sources mechanical services from Climatech but competes in adjacent scopes.
