SANYO is justifiably proud of being renowned for developing unique technologies, offering superior products and delivering
quality services. Since its formation back in 1958, SANYO Air Conditioners has enjoyed a number of 'world firsts’, from
introducing the world's first heat pump air conditioners in 1960, to introducing simultaneous heating & cooling GHP VRF to
Europe in 2005. Positive proof that SANYO is, and is committed to remain, at the cutting edge of product innovation
and forward-thinking dynamism.
Available in 2 pipe heat pump and 3 pipe heat recovery versions, the ECOi range combines advanced design, cutting edge technologies and R410A refrigerant to produce the most energy efficient and cost effective systems to date.
With a wider range of outdoor units, indoor units and control options than ever before, it is easy to see why choosing SANYO ECOi is a good decision all round.
SANYO introduced the company's first 3-pipe VRF system back in 1989 and this, together with our continuous programme of research and development has ensured that our products remain at the very forefront of innovation. 2006/7 sees the launch of many exciting new products including the latest generation of Electric VRF - the ECOi Multi Series.
Easy to justify... a good decision all round
- Smaller pipework, lower material costs
- Easy to maintain
- High efficiency
- Reduced life cycle costs
Easy to install... smaller pipework with longer runs
R410A has a higher operating pressure with a lower pressure loss than previous refrigerants. This enables smaller pipe sizes to be used, which take up less space in risers and also lead to reduced material costs.

Easy to design... simple design software
System design software
SANYO recognise that designing, selecting and preparing a professional VRF quotation can be a time consuming and costly process, especially as it is often also a speculative exercise. We have therefore designed proprietary software which is quick and easy to use and produces a full schematic layout of pipework and controls, as well as a full materials list and performance data. We cannot guarantee you securing the project, but we can certainly help you give it your best shot!
Accurate capacity control
To ensure that the compressor capacity is matched to building load as accurately and efficiently as possible, Sanyo has designed its range of 2 and 3 Way ECOi systems to operate with DC inverter and high efficiency fixed speed compressors. The system selects the most efficient compressor to operate by dynamically monitoring the building load and choosing the best compressor combination to run.
Easy to position... compact footprint
The compact design of the ECOi outdoor units, means that they fit into a standard lift and are easy to handle and position when on site. The small footprint and modular appearance of the units ensure an attractive installation.
Easy to select...8HP to 48HP systems
With 15 indoor model styles available, ECOi systems are the ideal choice for multiple small capacity indoor unit installations as up to 40 indoor units can be connected to systems of 24HP and above.
Easy to commission... auto addressing
Simple set-up procedure including automatic addressing of connected indoor units. Configuration settings can be made from an outdoor unit via a remote controller.
Easy to control... variety of control options
There is a wide variety of control options available to ensure that the ECOi system provides the user with the degree of control that they desire.
