NHJ series is designed based on our high efficiency model, Efficio series, and adopts our unique waste hot water heat exchanger. It contributes cost saving and lower environmental impact.
Pursuit of energy saving
Waste heat recovery rate
Operation by only Waste hot water at cooling load up to 53%
Equipped with optional waste hot water independent operation mode that does not use fuel except during startup.
Operation by only waste hot water without fuel consumption is possible at cooling load up to 53% even in normal mode. The large amount waste hot water type can operate without fuel consumption at cooling load up to 60%.
Fuel gas consumption rate
Reduced machine weight
Lineup of large amount waste hot water type
Applying compact and high-performance heat exchanger used in Efficio series and optimization for even the smallest details, we achieve 30% weight reduction compared to conventional model. It contributes to reduction of installation cost and reinforcement for the existing foundation at renewal.
Large amount waste hot water type is available to match waste heat amount from co-generation equipment.
