AIR TREATMENT
-- Electrical heater for protection of the components of
the electric panel. This is compulsory if the outdoor
temperature is lower than -8ºC WB. With an outdoor
temperature ower than -16ºC WB will be compulsory
a reinforced resistance.
-- Compressor with protection for low temperature
(supplementary crankcase heater). This is compulsory
if the outdoor temperature is lower than -8ºC WB.
-- Dampers with spring for automatic closing in case
of a tension cut. This is compulsory if the outdoor
temperature is lower than -8ºC WB.
-- Electrical heater for antifreeze protection of dampers
of mixing boxs. This is compulsory if the outdoor
temperature is lower than -12ºC WB.
-- Circuit of the hot water coil with antifreeze protection
according to the water temperature. This is
compulsory if the outdoor temperature is lower than
-20ºC WB.
■■ Humidity
-- Stop-drop in the indoor air
coil (optional from model
415 to 960 and included in
models 1100 and1200).
-- Recommended in cases
where a high moisture
content in the air is
foreseen or when the air
flow is high.
-- Stop-drop in the outdoor
air intake.
-- Tropicalised electric panel.
-- Tropicalised motors and
fans (please consult).
Indoor stop-drop
■■ Comfort / heating options
-- Hot water auxiliary coil, with three-way valve. This
optional always incorporates an anti-freeze thermostat
as safety system.
-- Auxiliary electrical heaters. With this option, the air
flow controller is compulsory to be selected.
Nevertheless, if the unit with electrical heaters
incorporates supply plug-fan, it is not possible to
select the optional the air flow controller, since the
proper fan realizes this function.
-- Natural or propane gas
burner with modulating
actuator, except models
415 and 480. Available
for all assemblies
except top and bottom
outlet. With this option,
it is compulsory the
differential pressostat for
controlling the air flow
that stops the burner
in case of fire. It is also recommended to have the
differential pressostat option for detecting clogged
filters.
In case of units with gas burner and supply plug-fan it
is not possible to select the pressostat for the air flow
controller, since the proper fan realizes this function.
■■ Corrosion
-- Coils (outdoor, indoor and/or auxiliary) with copper
pipes and copper fins.
-- INERA® coils (outdoor, indoor and/or auxiliary) with
copper pipes and fins of an aluminium alloy, of high
performance and great resistance to the corrosion.
-- Coils (outdoor, indoor and/or auxiliary) with copper
pipes and aluminium fins with polyurethane and
blygold® coating.
-- Condensate drain pan for the indoor circuit in stainless
steel.
