ECO3 Commercial AC Retrofitting

What Is ECO3?

Smarter compressor control — immediate savings.

ECO3 is an intelligent control device that reduces the run time of compressors in multi-split commercial air conditioning systems. Retrofit it to your existing VRV/VRF system — no replacement required. By optimising when and how long each compressor runs, ECO3 reduces total electrical consumption by approximately 10% per system.

Compatible with virtually all multi-split VRV/VRF commercial AC systems
Works with wall-mounted, ceiling, floor-mounted, ducted, and cassette types
Low upfront cost vs. full system replacement
No change to cooling comfort experienced by occupants
Reduces compressor wear — lower long-term maintenance cost

~10%

Electricity reduction per systemImmediately after installation, with no changes to your AC equipment or occupant comfort.

How It Works

Optimise what you already have.

1

Retrofit to your existing system

ECO3 connects to your existing VRV/VRF system. Cabling runs from the weatherproof ECO3 enclosure to the outdoor condensing unit.

2

Optimise the compressor cycle

ECO3 determines when and for how long each compressor runs to maintain its most efficient operating state.

3

Reduce run time and energy consumption

Less unnecessary run time = approximately 10% less total electrical consumption — without changing occupant comfort.

ECO3 reduces the run time of compressors — reducing total electrical consumption by approximately 10%.

Who Is This For?

Any business with multi-split commercial AC

ECO3 is for everyone looking to reduce massive electricity costs from existing multi-split commercial AC systems

For everyone looking to reduce the massive electricity costs consumed by their existing multi-split type commercial air conditioners.

Additional cabling from ECO3 weatherproof enclosure to outdoor condensing unit — minimal installation works

Additional cabling works from the ECO3 weatherproof enclosure to the outdoor condensing unit — minimal site disruption.

💰

Low CapEx vs. Replacement

Cost is relatively small compared to replacing the entire multi-split system. Achieve savings without capital-intensive overhaul.
