Retra Light 350 kW boiler

Retra Light 350 kW boiler

Retra Light solid fuel hot water heating boilers, made of steel, are available for domestic use with capacities ranging from 18 to 98 kW, and industrial boilers with capacities ranging from 150 to 600 kW. They are designed for heating individual homes and public utility buildings. They feature microprocessor-controlled coolant temperature control and forced-air combustion. The system distributes the airflow throughout the entire firebox to ensure complete combustion.

ADVANTAGES

• Increased firebox volume;
• The working cycle duration has been extended;
• Electronically controlled primary and secondary air supply;
• Increased fuel efficiency due to 80-93% efficiency and complete fuel combustion;
• The thickness of the inner wall of the heat exchanger is 4 mm (up to 100 kW), 5 mm (150-600 kW), which ensures a long service life.

The introduction of certain technical innovations, such as regulation and direction of air flow into the combustion zone, secondary air supply, electronic control of operating parameters, and programmable modes, have enabled a new technological level of energy efficiency. A control panel, supplied with the boiler, controls the air supply fan and circulation pump.

ADDITIONAL FEATURES

• Possibility of installing a pellet torch burner with a hopper.
• Possibility of inserting an auger feed with a hopper for wood chips, sawdust, grain and nut husks, corn cobs, etc.
