Hot water fire-tube boilers ATON SAB Dual 0,19-0,8

ATON SAB D (Dual) - a boiler with reversible development of a torch and horizontal smoke pipes, is designed to work with gas and oil burners. This model consists of two boilers of equal capacity, arranged vertically one above the other in a common housing.
Design allows to significantly reduce the area for installation of equipment, as well as reduce heat loss.
The reliability of the construction and the safety of the operation of the boilers are guaranteed by the exact ratio of the thermal loads to the volume of the combustion chamber and the heat exchange surface, thereby achieving a high efficiency.
The boiler SAB D (Dual) combines excellent qualities, such as:

  • high efficiency,
  • reliability in operation, 
  • long service life.

The boiler is designed for heating networks with a working temperature of the coolant from 60 to 115 ° C.

  • High flexibility in operation when changing power is required, high reliability in case of boiler failure (half the power is always guaranteed in case of one of the modules fails).
  • Two-way gas flue system in the boiler heat exchanger ensures reduced emissions of harmful substances into the atmosphere.
  • The steel heat exchanger of the boiler is resistant to temperature differences between the supply and return lines within the permissible temperature range (115 ° C - 60 ° C).
