Hot Water Hydrobox (80°C)
HIGH TEMPERATURE HOT WATER MODULE FOR HITACHI SET-FREE VRF
The Hydro Free high-temperature system is ideal for high-temperature hot water needs for renovation projects, as heat is recovered via the CH box on indoor units operating in cooling mod.
A single unit to meet 2 needs: heating and DHW
The High-Temperature Hydro Free system produces hot water up to 80°C from renewable energy (no anti-legionella cycle required)
For 2-Pipe AND 3-Pipe FSXNSE and FSXNPE Systems
Requires additional PC-ARFWE Controller

Features and Benefits
- High-temperature heating: combined with the VRF Sigma or SET FREE Mini 2/3-pipe.
- Constant DHW production: combined with the VRF Sigma or 3-pipe SET FREE Mini.
- Timed DHW production: combined with the VRF Sigma or 3-pipe SET FREE Mini.
- 1 box solution – 16kW
- Smart Cascade Operation – Single Module R410a operation only up to 45°C
- Up to 80°C – the second R134a cycle occurs only if the inlet temperature is greater than or equal to 30°C or when the outlet temperature is greater than or equal to 45°C.
- Ideal for commercial hot water applications in environments where cooling demand via VRF produces waste heat. Examples IT Suites and Gymnasiums.
