GENERAL FEATURES
The HMA series is designed for demanding applications such as indoor swimming pools and industrial facilities, where precise humidity control is necessary. These units allow for efficient air dehumidification combined with energy recovery, ensuring comfort and efficiency.
Construction and Components
Carpentry
The structure of the HMA units is made of high-strength galvanised steel sheet, designed to ensure durability and stability in demanding environments. The panels are removable, allowing quick access to all internal components to facilitate maintenance and service operations. The design incorporates acoustic and thermal insulation to reduce vibrations, minimise energy losses and improve comfort in the installation.
Refrigeration circuit
The refrigeration circuit is designed in accordance with European regulations and equipped with high-quality components from international manufacturers. It incorporates a dehydrator filter, expansion valves, and Schrader-type service ports to facilitate control and maintenance tasks. The system uses high-performance refrigerants, optimising energy efficiency and operational stability under variable conditions.
Compressors
The compressors used are high-efficiency hermetic types, selected to provide reliable and quiet operation. They are mounted on anti-vibration supports that reduce noise transmission to the structure. Additionally, they include thermal and electrical protections that ensure safety and prolong the equipment's lifespan.
Condensers and evaporators
The heat exchangers are constructed with copper tubes and high-efficiency aluminium fins, optimised to maximise thermal transfer. This design improves the overall performance of the equipment, reduces energy consumption, and ensures stable operation even under high humidity or temperature conditions.
Heat recovery unit
The HMA units incorporate a high-efficiency heat recovery system that allows for the reuse of energy contained in the extracted air. This system significantly improves the overall performance of the equipment, reducing energy consumption and optimising the thermal conditions of the treated environment both in winter and summer.
Ventilation
Equipped with high-performance centrifugal fans, the units ensure a constant air flow and adequate pressure available for ducted installations. The design of the ventilation system is aimed at maximising energy efficiency and reducing noise levels during operation.
Filtration
The filtration system consists of easily accessible and removable air filters, designed to retain particles and protect the internal components of the equipment. This ensures better quality of the treated air and helps maintain the system's performance over time.
Control and Regulation
The control of the equipment is carried out through an advanced electronic system with a microprocessor, which allows for precise management of the operating parameters. It includes temperature and humidity regulation, fan control, and monitoring of the main elements of the system, ensuring efficient, safe operation that is adaptable to the needs of the installation.
