SANYO’s policy of product development continues with the expansion of the ECOi Mini, the 2 pipe heat pump small VRF system specifically designed for the European market.
Offering between 11kW and 16kW cooling capacity in 3 sizes and up to 9 indoor units connected, the ECOi Mini sets new standards of performance and flexibility.
Utilising R410A and DC inverter technology, SANYO offers VRF to a new and growing market.
Forming a new key part of the SANYO VRF line up, the ECOi Mini is compatible with the same indoor units and controls of the electric and gas powered VRF range.

Extended compressor life
The compressor running time is monitored and optimised by a microcomputer to ensure that there is no imbalance in the operation times of compressors on the same refrigerant circuit.
Longer piping means greater installation area
Reducing the refrigerant volume by reducing piping size has extended the piping actual length to 150m (175m equivalent piping length).
