THE PATENT
2x1 by Galletti: Evolution in air conditioning
Only someone who has been designing and manufacturing heating and air conditioning units for 45 years could have conceived a product which transcends
the limits of existing technology.
2x1 is an indoor unit for hydronic heating and cooling systems which combines two operating modes in a single unit.
Thanks to an exclusive patented design, 2x1 can function as a heater without the aid of a fan, exploiting instead the principle of natural convection.
In summertime 2x1 offers the advantages of the best fan coil units, cooling, dehumidifying and filtering the air inside the room.
The exclusive patent combines 2 different operating modes in a single unit:
2 different air flow routes inside the unit and 2 distinct heat exchangers make it possible to switch over from natural convection heating to ventilated cooling
or heating.
Heating: 3 operation mode, 5 thermal emission levels:
st
> 1
level - convection heating mode, fan off, flap open. The thermostat
controls the room temperature by acting on the valve (optional), which
interrupts the flow of water. The unit can be shut down immediately by
positioning the air outlet flap in the closed position.
> 2
nd
level - convection heating mode, fan speed set on extra low, flap
open. The thermostat controls the room temperature by acting on the fan
and valve (optional), which interrupts the flow of water.
