High output gas condensing systems
Luna Duo-Tec MP+
Single or cascade centralized heating systems installations
READ MOREThe range of Luna Duo-tec MP+ consists of wall-hung commercial condensing boilers, with output between 35 and 150 kW (50/30°C).
Luna Duo-tec MP+ are heating only boilers for centralized systems with the possibility to be connected to a domestic hot water tank.
Luna Duo-tec MP+ can be mounted on a frame to be installed also in the middle of plant rooms. The frame is common for to all models, for single and cascade installation.
Cascade option for greater heating demand , up to 16 boilers

Cascade option for greater heating demand , up to 16 boilers
Characteristics
- Modulation up to 1:9 (1:5 for 1.115, 1.130 and 1.150) reduces on-off cycles for improved efficiency and energy savings
- Large back-lit display
- Stainless steel burner (metalic fiber for 1.110 model)
- Low water content heat exchanger for a rapid response to system heating demand
- Electronics that allow up to 16 boilers in cascade format
- Premix air-gas unit ensures that the burner constantly has an optimal air/gas ratio, for better efficiency and lower energy consumption
- Accessories for single or cascade installation, for direct wall hung mounting or upon a metal hanging frame
