SIGMA E

WITH A TRAY AT THE RIGHT SIDE




Taking care of the environment and air quality in Poland, we have created a new eco-friendly product. Sigma E is a boiler that meets the highest strict standards of exhaust purity and efficiency. This boiler is ECODESIGN and 5 CLASS certified. Thanks to the new patented retort burner and changes in the water jacket Sigma E can boast of low emission and economy. Caring for the convenience of users, the system of mechanical cleaning of the exchanger is standard. High-quality materials used to produce the boiler. An intuitive and user-friendly controller with a color touch display with adjustable angle. Completely new ceramic catalysts arranged around the hearth. Dedicated ceramic deflector with a new shape. Convenient revision system. Modern design and colors characteristic for our company. All this makes Sigma E the leader in the eco-pea coal class with the ECODESIGN certificate.

Product characteristics:
- additional ceramic catalysts arranged around the furnace
- dedicated deflector
- mechanical exchanger cleaning system
- a new generation of retort burner with a combustion air supply system

1The maximum area of ​​heated rooms has been estimated for a unit
heat demand q = 80 W / m2.
2Capacity of the fuel tank for the bulk density of eco-peas equal to 0.8 kg / dm3.
3The weight of the boiler depends on its additional equipment.


The height of the boiler can be additionally adjusted using the attached feet.
The feet have a regulation range from 38 to 50mm.


ATTENTION! When ordering a SIGMA E boiler, specify the side of the storage tank (left or right).


Adaptation of the SIGMA E boiler to the closed system (NZ version) should be reported when ordering the boiler due to the impossibility of subsequent installation.


Elements of additional equipment should be reported when ordering the boiler due to the lack of possibility of subsequent installation.
