Luna Duo-Tec MP+

High output gas condensing systems

Single or cascade centralized heating systems installations

Commercial

Wall-Hung / on frame

The 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, allowing installation even in the middle of plant rooms. The frame is common to all models, both for single and cascade installations.

Cascade option for greater heating demand, up to 16 boilers

(1) Low temperature: return temperature (at boiler inlet) for condensing boilers 30°C, for low temperature boilers 37°C and for other heaters 50°C.
(2) High temperature setting means 60 °C return temperature at boiler inlet and 80 °C flow temperature at boiler outlet.
