Gas Condensing Boiler Luna Duo-tec MP+ 1.90

Description

Gas Condensing Boiler Baxi Luna Duo-tec MP+ 1.90

Main features:

• high modulation ratio (1:9);
• nominal efficiency 50/30°C: 105%;
• high efficiency full modulating circulating pump included in the boiler;
• heat exchanger with combustion chamber and stainless steel coil hydraulic system, single chamber models from 50 to 70
kW, double chamber models 90 - 150 kW
• low water content in the exchanger that means very limited thermal inertia and therefore a rapid response to the variations
in thermal energy required by the system;
• premixing unit with double clapet technique, ensuring that the burner constantly has an optimal air/gas ratio independently
from the number of fan revs, keeping consumption to a minimum and always guaranteeing correct combustion and
consequently a reduction in polluting emissions;
• NTC sensor on flow and return for a more precise modulation;
• digital PCB with latest generation double microprocessor;
• control panel with large back-lit LCD;
• stainless steel burner for 1.50, 1.70, 1.90, 1.130 and 1.150 models and metalic fiber for 1.110 model;
• adjustable speed fan and insulation for a noiseless operation;
• electronics that allows great flexibility in highly diversified contexts. With specific accessories that can also be installed
inside the boiler, it is possible to control mixing zones, daily and weekly programming of heating and sanitary functions,
cascade, recirculation and other functions;
• 0-10 V control available as optional;
• accessories for single or cascade installation, for wall hung mounting or with metal frame;
• hydraulic accessories to install from 2 to 6 boilers in cascade;
• operation with natural gas and LPG (with LPG convertion kit).
