Construction and Components
Carpentry
The structure is made of hot-dip galvanised sheet metal, ensuring high resistance to corrosion and a long service life even in demanding conditions. The panels are removable, allowing quick access to all internal components to facilitate maintenance and inspection tasks. The condensate tray is designed to ensure proper drainage of water.
Refrigeration circuit
The refrigeration circuit is made with top brand components and in accordance with current regulations. It includes a dehydrator filter, expansion devices, and Schrader type service valves to facilitate maintenance, charging, and system control operations. The design is optimised to maximise energy efficiency and reliability.
Compressors
The compressors used are high efficiency, selected based on the model to ensure the best performance. They are equipped with thermal protections and mounted on rubber anti-vibration supports that significantly reduce noise levels and vibrations during operation.
Condensers and evaporators
The coils are constructed with copper tubes and high efficiency aluminium fins, optimised to improve heat exchange. This design allows for high performance with a compact size, also ensuring long durability of the unit.
Ventilation
They incorporate high-performance centrifugal fans, designed to provide a constant air flow even in ducted installations. Their operation ensures an even distribution of treated air throughout the space.
Filtration
Equipped with easily removable air filters for cleaning and maintenance. These filters protect the internal components of the equipment and help improve the quality of the treated air.
Control and regulation
Electronic control system using a microprocessor that allows precise management of the operating parameters of the equipment, ensuring optimal control of humidity and temperature at all times.
Refrigerant
Uses eco-friendly refrigerants in accordance with current regulations, selected to provide an optimal balance between energy efficiency and low environmental impact.
