The type of heat exchanger is «high-speed water-tube» (water circulates inside the tube). Together with a smooth power modulation and stable efficiency, it can significantly increase resource savings and comfort. The wall thickness is 3.2 mm, and the maximum operating pressure of the coolant in the heating system is 6 atmospheres. The heat exchanger is coated with a special high-temperature anti-corrosion enamel, and alongside with it, it is treated from the inside with a specialized inhibiting compound that provides protection against aggressive effects (oils, salt solutions, etc.), which also contributes to the durability and reliability of Lemax equipment.
- Efficiency - 92%.
- Equiped with original European components:
- SIT 845 SIGMA automation,
- POLIDORO injection microflame torches,
- BRAHMA means of control and ignition of the flame.
- Smooth power modulation in the ratio of 1: 3, which provides the minimum load on the components of the heating system.
- Automatic ignition: reducing equipment maintenance costs.
- Low power consumption.
- Easy maintenance and familiar components.
- High reliability: built-in modern protection against
- freezing,
- overheating,
- reverse thrust in the flue duct,
- clogging of the heat exchanger,
- overpressure of the coolant in the heating circuit.
- Resistance to gas pressure surges in the range of 6-25 Mbar and network voltage of 180-245 V.
- 2 year warranty.
- Advanced connectivity:
- indirect heating tank;
- outdoor temperature sensor;
- control of the boiler circulation pump and / or indirect heating tank load,
- thermostats for regulating the temperature of the coolant depending on the conditions in the room,
- systems of remote control and management by the OpenTherm protocol (or RS485).
