TECHNICAL FEATURES
The ALKON 90 boiler is a low water content thermal element
about 2,64 gal (10 l), with a built-in premix gas burner, for
heating only.
It is mainly used as element for the modular boilers in casca-
de (max 4 boilers).
PECULIAR CHARACTERISTICS:
1)
modular structure to tall integration.
2)
mainly for outdoor installation
3)
prearranged for quick installation '' Plug and Play '' also
in cascade of up to 4 modules.
4)
modulation ratio of the single module
5)
control for every single module, with display and
diagnostic
These boilers have an input head power of:
341,000 Btu (99,94 kW), These boilers are designed for use
on gas category IV.
The ALKON boiler is supplied complete with all the safety
and control devices in accordance with all the current
regulations and its technical and functional features comply
with the regulations prescribed by:
ANSI Z21.13 / CSA 4.9 - Gas-fired low pressure
steam and hot water boilers
