SZAFIR

Coal boiler

SIMPLE AND CONVENIENT OPERATION

Boiler SZAFIR is characterised by easy operation. It has a movable, cast iron grate, which allows ash removal without opening the door. The large capacity of the top-loading chamber allows to long work with one load, and the large door opening facilitates convenient refuelling. It has a three-chamber structure that improves combustion efficiency and reduces exhaust emissions.

FROM THE SMALLEST TO LARGE HOUSES

The SZAFIR boiler can be used to heat small areas, as well as houses with an area of up to 305 m². The advantage of the SZAFIR boiler is the possibility of refuelling during operation without deterioration of the boiler’s heating properties (as in boilers with a feeder).

SMALL, COST-EFFICIENT AND CHEAP IN UTILISATION

This is one of the smallest boilers on the market. Thanks to its small dimensions, it can be installed in small and low boiler rooms. The SZAFIR boiler is characterized by low fuel consumption, thanks to the boiler efficiency amounting to 90%. Its undisputed advantage is that it does not require power supply, and the control is carried out manually or automatically using a chimney air draught control device.

RELIABLE DESIGN = LONG SERVICE LIFE

The solid and durable SZAFIR boiler is made of certified boiler sheets up to 6 mm thick (12 kW boiler weight: 360 kg), has a three-chamber structure, which reduces the risk of corrosion and sinters. It has a long warranty – up to 5 years – of the tightness of the body’s welded parts.
