Gas condensing boiler Ecocondens Crystal 80 kW system
The ECOCONDENS CRYSTAL 80 wall-mounted condensing boilers, with an output of 80 kW, are an ideal solution for heating multi-family buildings, guesthouses, or office buildings. They can operate as standalone units or in a cascade configuration. By combining the boilers in a cascade (up to 6 units in a system), it is possible to achieve outputs of up to 480 kW, heating large facilities such as production halls.
After appropriate adjustment, the boilers can operate on 2E-G20 (GZ-50) or 3P-G31 (liquefied gas) gases. • Innovative heat exchanger design, which makes the boilers compact in size relative to their power output,
• Boiler venting is achieved through a vent mounted on the heat exchanger,
• Modulating electronically controlled fan ensures low energy consumption,
• Burner with a wide modulation range ensuring low NOx emissions (class 6),
• Two factory-installed adapters with measuring ports: Ø100 air and Ø100 combustion,
• NTC sensor for the hydraulic clutch included with the boiler,
• Open-Therm communication protocol,
• Compatible with domestic hot water tanks with a minimum coil output of 25 kW,
• In cascade systems, boilers are connected in series using a cable supplied with the boiler. The first boiler acts as the MASTER boiler (acting as the manager), while the remaining boilers operate as SLAVEs, so there is no need to connect an additional external manager.
• A high-efficiency circulation pump (EEI ≤ 0.23) with a head of 8 m.
