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
