1.7 Applications
The AP series unit heaters are used in the industrial and civil sectors, in rooms where you want to
raise the temperature having hot process or central heating water available, or you want to lower the
temperature by having cold water or chiller available.
They are also used in shopping centres, workshops, showrooms, gyms, dairies, etc.
In the livestock industry, they can be used in pig farms to heat farrowing rooms, weaning halls, lean-
tos and corridors, or in chicken farms, in tunnels with longitudinal, natural and chimney ventilation. In
agriculture they are used for heating or cooling greenhouses and mushroom houses.
The materials used guarantee reliability and durability.
The exchanger is fitted with copper tubes and aluminium fins with increased pitch and thickness; it is
painted with cataphoresis, a treatment that gives it considerable resistance to corrosion;
The structure of the hot water heater is made of polypropylene, a material with a low specific weight
and high chemical (corrosion and acid) and tensile strength.
The fans used on the AP series are single-phase 4- or 6-pole axial fans (with condenser), with IP54
protection (for the AP15 and AP25 versions, IP44). The motors have class F insulation and are equipped
with automatic reset thermal protection. The screws are made of stainless steel.
