SANYO's Brand Vision

SANYO HVAC consistently builds new ideas to help build
your business. By delivering multi-zone options, space-saving
and environmentally friendly designs, our solutions are evolving,
improving solutions.

Flexible Combinations: ECOi allows multiple indoor unit
combinations that provide you with the utmost in flexible
solutions. The system also allows multiple unit connectivity
providing up to 130% of the total capacity of the condensing
unit. This provides for up to 17 indoor units connected to one
condensing unit.

Inverter Control Compressor: All ECOi systems utilize highly
advanced inverter controlled compressor technology. By varying
the rotational speed of the compressor, the inverter control can
precisely match the amount of refrigerant being delivered to
the needs of each zone. This intelligent approach helps realize
excellent efficiencies during partial-load conditions. This allows
all occupants to enjoy consistent room temperature, regardless
of any increases or decreases in the heat load during the day.
ECOi quite simply knows what you need, and when you need
it throughout the day. And even better, it does so with energy
efficiency in mind.

Lower running and life cycle costs: SANYO Ecoi VRF
systems are amongst the most efficient VRF systems on the
market, offering COPs in excess of 4.0 at full load conditions.
The system is also designed to make sure that we reduce the
running cost of each system by using our unique road map
control routine to ensure that the most efficient combination
of compressors are running at any one time. Improved defrost
sequencing also reduces running cost by defrosting each out
door coil in turn when conditions allow.

3-Way ECOiTM VRF Heat Recovery

Commercial of fice buildings are subject to fluctuating heat levels generated from electronic office equipment,
lighting and varying occupant levels. Also, hotels, nursing homes and other commercial living spaces often have
times when occupants will want either heating or cooling at the same time. The heat recovery system offers the
perfect solution for stabilizing the air temperature by providing all the features of a heat pump system - and the
added flexibility of simultaneous cooling and heating from one refrigerant pipe network.
