Deumidificatore Yety+ da incasso
Deumidificatore canalizzabile da incasso in parete verticale realizzato in polipropilene espanso sinterizzato (EPP) e struttura zincata da incasso (laccata o verniciabile).
The SLPK26 and SLPZ26 series dehumidifiers are high-performance appliances, designed to be paired with radiant panel cooling systems.
The YETY+ recessed units have been designed for vertical wall-recessed installation. They are produced in two versions:
- YETY+ PN recessed (code SLPK26), for dehumidification only
- YETY+ PR recessed (code SLPZ26), which adds 1,818 W of cooling to the dehumidification process
The galvanized recessed structure (code SLAC18), the lacquered grille (code SLAC19), and the paintable grille (code SLAC20) are supplied separately.
All units undergo leak testing and vacuum cycles, are charged with eco-friendly refrigerants, and operate using the same supply water used for the radiant panels.
All units also comply with European directives and bear the CE marking and relative certificate of conformity.
Each unit is equipped with:
- Air filter
- Condensate collection tray
- Electronic regulation board
- Pre- and post-cooling coils
- 35 dB fan
All units comply with European directives and bear the CE marking.
Field of use
The YETY+ PN units are designed to ensure effective dehumidification under thermally neutral air conditions, maintaining the same temperature as the air drawn from the environment.
The YETY+ PR units integrate the performance of the YETY+ PN series with cooling of the treated air, thanks to the 1,818 W condensing coil, making them ideal for meeting requests for additional cooling power and improving summer comfort.
The YETY+ PN and YETY+ PR dehumidifiers are suitable for applications in the residential sector and small-scale commercial sector. From a hydraulic perspective, the units must be connected to low-temperature manifolds and use the supply water of the radiant panels.
The nominal airflow of each unit is 260 m³/h, making the YETY+ PN and PR dehumidifiers suitable for treating environments with an internal volume between 260 and 325 m³, equivalent to approximately 90–120 m² of floor space, considering a room height of 2.80 m.
Operation
SLPK26 – Operating principle
The operating principle of the SLPK26 dehumidifier is as follows: moist air is drawn from the environment by the fan (M) and directed through the filter and the water pre-cooling coil (6), where it is cooled and brought to a condition close to the saturation curve.
Subsequently, the air passes through the evaporating coil (5), where it is further cooled and dehumidified.
Finally, the air passes through the condensing coil (4), where it is post-heated at constant humidity and returned to the required comfort conditions before being reintroduced into the environment.
SLPZ26 – Operation with plate heat exchanger
In the SLPZ26 version, the dehumidifier is not equipped with an air condensing coil, which is replaced by a plate heat exchanger (14) that allows the correct operation of the refrigerant circuit.
This solution allows to avoid heat load dissipation into the air, transferring the heat directly to the supply water. In this way, the unit's thermal load is dissipated into the water, ensuring useful cooling power in the environment.
The system makes the SLPZ26 version particularly suitable for radiant panel systems and for applications where efficient additional cooling is required, improving environmental comfort without unwanted heat dispersion.
ALL VERSIONS
Through a specific probe (LIMIT PROBE), the dehumidifier closes the water circuit if it detects a water temperature higher than 32°C, automatically excluding the compressor during the winter period.
The electronic board monitors frost formation on the condensing coils and, once a certain level is exceeded, automatically starts a defrost cycle.
These functions allow for the elimination of any maintenance intervention throughout the life of the product.
YETY+ PR VERSION ONLY
An integrated ambient probe allows for the regulation of the temperature at which the additional cooling must intervene, allowing the YETY+ PR dehumidifier to dose its intervention only when necessary.

Installation suggestions
Positioning and minimum technical spaces SLPK26 and SLPZ26
SLPK26 and SLPZ26 vertical dehumidifiers are normally installed recessed into the wall, taking care to first position the galvanized sheet structure; the wall box (supplied separately – code SLAC18) is first placed in a niche created in the wall, ensuring it is slightly larger than the recessed structure (L 715 mm x H 703 mm x D 240 mm) considering any thickness due to the fixing cement.
The height from the floor depends on aesthetic and functional needs; it is normally considered so that the cover grille is positioned above the baseboard.
ATTENTION: The front profile of the recessed structure must be flush with the finished plaster of the wall. The unit is then fixed to the recessed structure using the screws provided.
