SIGMA E – Eco-pea coal boiler intended for larger buildings in the range of 450-800 m², meeting the criteria of the Clean Air Program (36, 48, 69 kW).

• Increased water capacity of the boiler exchanger.
• The modernized retort burner ensures accurate fuel combustion, eliminating undesirable emissions.
• The blower equipped with air dosing modulation with the “ADAPTIVE CONTROL” system and the PID function guarantees stable fuel combustion.
• Reliable operation is ensured by the energy-saving, high-efficiency ABM gearmotor. The auto-reverse function works well when the fuel feeder is blocked.
• The furnace lined with ceramic catalysts burns aggressive emission compounds
• The boiler exchanger is composed of horizontal ceramic shelves and vertical fire tubes with economizers inside, which also create an automatic cleaning system.
• The K1PV4 controller allows you to operate 4 pumps and control one mixing valve. The standard includes the so-called weather sensor, and the control system can be expanded using an additional room controller and Internet module.
• SIGMA E has a number of thermal protections that guarantee proper operation of the boiler and safe use of the device, as well as the so-called fuel tank pressure equalization system.
• The feeder screw coil is made of one element.
• Possibility to change the opening direction of external doors.

Taking care of the environment and air quality in Poland, we have created a new ecological product. Sigma E is a boiler that meets the highest stringent standards of exhaust gas purity and efficiency. This boiler has an ECODESIGN certificate and a 5th CLASS certificate. Thanks to the use of our new patented retort burner and changes in the water jacket, Sigma E boasts low emissions and savings. To ensure user comfort, a mechanical exchanger cleaning system is standard. High-quality materials used to produce the boiler. Intuitive and user-friendly controller with a color touch display with an adjustable angle. Completely new ceramic catalysts placed around the firebox. Dedicated ceramic deflector with a new shape. Convenient inspection system. Modern design and colors characteristic of our company. All this makes Sigma E a leader in the class of eco-pea coal boilers with the ECODESIGN certificate.

Characteristic features of the product: – additional ceramic catalysts placed around the furnace – dedicated deflector – mechanical exchanger cleaning system – new generation of retort burner with combustion air supply system submitted to the Patent Office of the Republic of Poland
