STELT
STELT condensing boiler, made from AISI 316 Ti stainless steel with reverse flame
combustion chamber able to produce hot water at a maximum temperature of
110 °C. Connected to pressure jet burners operating on gaseous fuels.
Some of the product's main features are related below:
- inclined boiler body for condensate drainage support
- large cylindrical combustion chamber with reversed flame manufactured from
AISI 316 Ti stainless steel, TIG pulse welded, able to withstand acid condensate
attack.
- stainless steel gas passages with special profiles, placed around the combustion
chamber in order to extend flue gas development and consequently increase
heat exchange and increase boiler efficiency (obtaining low NOx emissions in
conjunction with Low NOx burners)
- heat exchange surfaces made from AISI 316 Ti stainless steel, welded with TIG
method, consisting of stainless plates characterized by a particular corrugated
shape being able to increase heat exchange surface, and facilitate droplet condensate
formation allowing adequate drainage.
- welded using TIG, MIG and plasma procedures, methods that guarantee stainless
steel main mechanical characteristics, without sacrificing corrosion resistance to
acid condensation.
- flanged flow connection and two system return connections for boiler differential
input and ensuring minimum possible temperature to take advantage of
condensing benefits even in case of medium-high temperature returns.
- flue gas chamber able to collect resultant condensate and discharge it through a
water trap connected to a neutralizer (where provided) to the waste water drainage
system.
- burner mounting plate, for attaching pressure jet burners for gaseous fuels use.
- heat dispersion surface insulation with thick glass wool mattress, protected with
steel varnished panels that can be easily removed
- front door with reversible steel sheet opening thermally insulated with ceramic
fiber.
Standard equipment:
- complete insulating casing
