Smart Cascade Cooling Cycle – Hitachi Innovation
-
The ability to operate one or two cooling cycles (Smart Cascade) based on internal and external conditions for energy savings.
-
Achieves required temperature regardless of external conditions.
-
Maintains stable performance even at -15°C ambient temperature.
-
Maximizes energy efficiency with minimal energy consumption.
-
Replaces existing boilers without needing any additional energy source.
High Thermal Efficiency
-
Yutaki S80 high-temperature heat pumps provide the highest thermal efficiency on the market, up to 18 kW.
-
Can produce hot water up to 80°C even in extreme external conditions (-20°C).
Control Options:
-
With the addition of the PC-ARFHE controller, you can program all heat pump functions, allowing the system to adjust its power to match the space’s needs for precise temperature control.
-
Specifically designed for the Hitachi Yutaki S80 high-temperature split heat pumps.
Ideal Solution for Boiler Replacement
-
Output hot water temperature up to 80°C even with an external temperature of -25°C.
-
Perfect for replacing existing boilers in installations with high-temperature heating systems (e.g., radiators, steel panels, aluminum panels).
-
Smart Cascade system combines optimal performance for low temperatures and combined operation for high temperatures.
-
Uses a combination of 3 heat exchangers for high efficiency.
