11.3 - Reheating and humidity control (optional)
Electrical heating (and dehumidification system)
The electrical heaters can largely keep the correct
temperature with dry bulb. The elements are made of
aluminum with high efficiency fins to keep a low pow
er density on the surfaces. The ionization effects are
removed thanks to the low surface temperature of the
elements.
The stages of the electrical heaters are distributed on
the 3 phases to avoid balancing problems.
There are three steps, two contactors, temperature
electronic control of the ON-OFF type, safety ther
mostat with manual reset, magnetothermal switch against short circuits, harness protection against pos
sible casual contacts.
When the electrical heating is installed, the dehumidification system is operating as well, and the relevant
humidity sensor and indicator are provided (see "Humidification and dehumidification system" for the de
humidification function).
It is possible to install the electric heating matched with the hot gas or hot water reheating. In this case,
refer to the paragraph "Hot gas reheating" or "Hot water heating".

Hot gas reheating (and A/W/D/F/H unit optional dehumidification system)
Hiflex can be supplied with a reheating system using the heat that is normally sent to the condenser to
heat the air, saving energy. This system is activated during dehumidification (in fact, the relevant humidity
sensors and indicators are provided) when the temperature decreases under the set value: in this way
no additional energy is required for the reheating.
