Elba DualCast-iron, floor-standing boiler
ELBA DUAL
ELBA DUAL is an innovative range of floor-standing boilers,
designed and manufactured by Fondital. Having thermal
outputs ranging from 24 to 73 kW, ELBA DUAL can be
equipped with oil-or gas-fired blown burners.
The heat exchanger with three flue gas passes is made of
cast-iron (EN-GJL-200). The combustion chamber is
engineered for the flame to fully develop and reach a wide
exchange area, which absorbs high heat while keeping the
superficial thermal load on its walls low. The three flue gas
passes, the high efficiency combustion chamber with wet
bottom, and the flue gas passes profiles, which optimize the
heat exchange, allow ELBA DUAL to be classified among
high-efficiency heat generators.
The heat exchanger is fully insulated by a high-thickness,
glass-wool layer, avoiding cost-affecting heat losses.
The casing is manufactured with electro-zinc plated metal
sheet, finished by epoxy-polyester powder paint for longer
lasting life time.
The control panel includes CH temperature selector (49°C/82°C range), thermometer, power on switch with light, manual reset safety thermostat, and lights indicating pump and burner operation and overheating shutdown.Behind the control panel door, space is provided for installation of optional equipment such as a thermoregulation control unit or a programmable timer.
