- High efficiency condensing boilers designed for heating only, in power ratings of 50, 60, 75, 100 and 120 kW, for single installations or cascaded combined with remote DHW storage tanks, or for an instantaneous DWH production.
- R1K 50 and R1K 60 are single condensing exchanger boilers, while R1K 75, R1K 100 and R1K 120 are dual condensing exchangers.
- The ONE-TECH® system is equipped with a stainless steel heat exchanger 100% made in Radiant with wide Ø 28mm single-pipe coils.
- These boilers, in addition to size advantages (70 cm width for 75 kW, 100 kW and 120 kW), offers great flexibility of installation in centralized systems, as well as many advantages in terms of performance, such as 1:20 Air/gas modulation ratio (75, 100 and 120 kW) and the possibility of excluding one of the two boilers in case of failures (models 75, 100 and 120 kW) in order to avoid the system shut down by making the other boiler running.
- ONE-TECH® heat exchanger 100%, Ø 28 mm STAINLESS STEEL coils.
- Air/Gas modulation ratio 1:20 (75 kW, 100 kW and 120 kW models) for higher efficiency and lower consumption both in heating and DHW production modes.
- It can be combined with a plate heat exchanger or hydraulic separator.
- IPX5D protection rating.
