Sigma E is a modern and ecological boiler fulfills the highest standards of cleanliness and efficiency. It is a leader in the 5th class of eco-pea coal boilers and is certified by Ecodesign. The boiler uses a new and patented retort burner, also changes in the water jacket, thanks to which the furnace is economical and has low exhaust emissions. The Sigma E boiler has been equipped with a mechanical cleaning system for the exchanger and an intuitive touch screen controller. The boiler construction was made of high quality materials, and new ceramic catalysts were placed around the furnace.

The boilers meet the energy and emission requirements of class 5 of the PN EN 303-5: 2012 standard and have the Ecodesign Certificate.

Standard equipment:

ADAPTIVE CONTROL,
K1Pv4 controller,
leveling feet
blowing fan
analog thermometer,
ash drawer,
extension of the flue with a throttle,
tank cover opening sensor,
fan speed sensor,
ceramic deflector,
ceramic linings of the boiler chamber,
mixing valve controller (in the K1P controller)
mechanical exchanger cleaning system.

Additional equipment (extra charge):

GSM module,
Internet module,
WIFI internet module,
firefighting system "Strażak",
NZ to the closed system,
DK LOGIC 100 regulator,
room regulator DEFRO SPK Lux,
DEFRO MZ module,
SPK Lux wireless regulator,
set for RS wireless communication

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

Product characteristics:

- additional ceramic catalysts placed around the furnace
- dedicated deflector
- mechanical exchanger cleaning system

The boiler heat exchanger was made of certified boiler steel / grad. P265GH / 6 mm thick

High boiler thermal efficiency of up to 88% thanks to increased heat recovery from outgoing boiler fumes

ADAPTIVE CONTROL control - regulation of boiler operation based on air flow through the exchanger

The possibility of changing the direction of opening the external door,

NZ version with reinforced construction and built-in coil adapted to work in a closed system (optional extra payment, installed on customer's request)

Combustion chamber with a highly efficient retort burner inside

feed screw made entirely from one piece

Fuel tank lid open sensor installed

Pressure equalizing system in the fuel tank

The manufacturer grants a 5-year warranty on the tightness of the heat exchanger and 2-year smooth operation of the boiler and other elements.

System enabling mechanical cleaning of the heat exchanger (in standard)

Energy-saving geared motor with reverse in case of blocking the fuel feeder

The K1P v4 controller with a colored touch panel can support 4 pumps (heat, DHW, circulation, floor) and a mixing valve. As an option it is possible to control via GSM or INTERNET (additionally payable).

Stabilization of the combustion process by a ceramic catalyst

K1Pv4 Controller

Functions carried out by the controller

modern ADAPTIVE Control with the use of a turbine flowmeter ensuring optimal selection of fan and feeder operation parameters;
the ability to check the history of the last twenty alarm states of the boiler;
an option to download the temperature history to the USB external memory;
option of cooperation with an exhaust fan module;
control of the fan and screw feeder;
control of the mixing valve actuator as standard;
weekly control;
control of central heating and hot water pumps;
control of two additional pumps;
the possibility of connecting a room regulator with RS or traditional communication;
option to connect the DEFRO GSM module;
the option of connecting a new version of the DEFRO Internet module that enables the remote change of boiler operation parameters (access to the user and service menu);
option of controlling two additional valves by means of DEFRO MZ modules;
operation of the gearmotor with reverse operation (not applicable to the PZ version);
a large, color graphic display with a touch panel and an adjustable screen tilt screen;
temperature sensor for central heating, hot water, valve, return, additional, flue gas and outside temperature;
temperature protection (thermals);
screw temperature sensor (protection);
high quality housing.
