1.1 Introduction
Dear Customer,
ALHENA TECH K 50 is a high-efficiency, low emissions
premix condensing heat generator
with
heat exchanger in s/steel
and incorporated DHW production, equipped with a microprocessor
control system.
DHW production is ensured by a 50-liter hot water tank integrated in the unit.
It can run on
Natural Gas
(G20),
Liquefied Gas
(G30-G31),
Propane Air
(G230) and, thanks to
the
“Hydrogen plug-in”
system, self adjusts to also work with mixtures of
natural gas and hy-
drogen
(Natural Gas/Hydrogen mixtures 80%/20%), that will soon arrive in Europe to fight global
warming.
The sealed chamber unit is suitable for indoor installation or outdoors in a
partially protected
place
