Smarter Systems. Greater Efficiency.

Solar-Driven Digitally Controlled Chiller

Solar PV powers the chiller directly before surplus electricity is supplied to the building grid, reducing conversion losses and lowering installation costs.

Smart Fan Coil Units (FCU)

Smart FCUs operate at higher chilled-water temperatures while automatically adjusting fan speed to maintain comfort with lower energy consumption.
