Engineered Air Distribution, Fabric Ducting & Specialist HVAC Solutions for Commercial, Healthcare & Industrial Buildings

ecoHVAC is a long-established Australian supplier of engineered HVAC equipment, specialising in air distribution systems, fabric ducting, hydronic components, UVC germicidal solutions, air-pressure stabilisation and critical-environment ventilation products. Their engineered range supports complex HVAC technical projects across commercial, healthcare and industrial sectors.

Serving Australia and New Zealand since the 1970s, ecoHVAC supports consulting engineers, mechanical contractors and facilities managers with high-performance, energy-efficient and standards-aligned solutions for complex building services projects.

ecoHVAC’s portfolio aligns with AS 1668.1/2, NCC Section J energy-efficiency requirements, Green Star performance frameworks, and IAQ reliability strategies used in hospitals, laboratories and commercial air distribution design.

Fabric Ducting & Air Dispersion – DuctSox, LabSox & DataSox

ecoHVAC is the primary Australian/New Zealand distributor for DuctSox textile air-distribution systems used in: These fabric duct systems are commonly used to distribute air uniformly through occupied spaces while maintaining low noise and stable comfort conditions.

• commercial buildings
• schools and universities
• sports centres and gyms
• industrial & food-processing facilities
• indoor pools
• data centres

Fabric ducting delivers air  distribution by combining air conveyance + uniform diffusion, producing highly consistent air patterns, stable temperature control and low acoustic impact.

Engineering Advantages

• Extremely lightweight vs sheet-metal ducting
• Reduced structural load and seismic considerations
• Rapid installation with fewer labour hours
• No condensation risk on porous fabrics
• Removable/cleanable textile ducts for hygiene
• Consistent induction and throw through jets, nozzles and perforation patterns
• Lower fan static pressure compared to metal ductwork

ecoHVAC provides diffuser layouts, fabric selection, perforation patterning and AS 1668.2-aligned air-pattern support using CFD and manufacturer design tools.

VAV Diffusers & Zone-Level Airflow Control

ecoHVAC supplies smart, decentralised VAV diffuser solutions for zone control in modern commercial buildings: In practice, these VAV diffusers operate in conjunction with room thermostats and optional BMS logic to maintain tight zone temperature control without bulky ceiling-mounted terminal boxes.

Solutions include:

• Smart Electric Square Swirl VAV Diffusers – motorised VAV actuation, swirl discharge, high induction
• Thermally Powered VAV Diffusers – self-regulating and require no external power

Engineering Value

• Decentralised VAV
• Reduced commissioning time
• Better zoning in open-plan offices & refurbishments
• Predictable induction and lower noise levels
• Solves ceiling congestion in refurbishment projects

Hydronic Equipment – Buffer Tanks, Expansion Vessels & Accessories

ecoHVAC supplies critical hydronic stabilisation components including: The range is designed to integrate with primary and secondary pump circuits to improve stability.

• Buffer tanks (500–15,000 L) to prevent short-cycling
• Expansion vessels for closed-loop systems
• Air/dirt separators
• Dosing pots and auto-fill units
• High-efficiency boilers and hydronic accessories

These products support steady-state chiller/boiler/heat-pump performance, assist in achieving NCC Section J5 requirements and strengthen lifecycle resilience in new and retrofit plant rooms.
