Product catalog summary

General Description
A comprehensive range of ventilation units with variable air-flow volume, featuring centrifugal fans with external rotor motors. These units are designed for modern installations, offering silent operation, robustness, versatility, and ease of installation. Airflow control is integrated with both manual and centralized digital device regulation options.

Characteristics
The units are equipped with centrifugal double inlet fans and an external rotor motor protected by thermal contact. Speed control is achieved through an electronic selector and a 5-stage converter integrated within the box. The radial impellers are high-performance, balanced both statically and dynamically, and are extremely silent and vibration-free. The casing is made of extruded aluminum profiles with high-impact resistant plastic corners. Panels are interchangeable, and a variety of accessories are available to facilitate installation.

Construction and Materials
The standard series features galvanized steel panels with 25 mm fiberglass insulation for sound absorption. Optional sandwich panels and acoustic panels with 50 mm insulation are available upon request. The use of metallic metric thread screws ensures quick and professional service.

Technical Specifications
Various models are available with different power, speed, and temperature specifications. All models operate at 230V and 50Hz frequency. Motor protection is rated at IP 44 or IP 54, depending on the model. Detailed specifications for each model, including power, intensity, speed, and condenser values, are provided.

Operating Control and Regulation
The units feature a 5-speed standard controller that provides interference-free speed regulation. Connections are external, using RJ45 connectors for easy installation. The controller supports digital communication, allowing long-distance operation and control of up to 12 units in series. Additional features include external ON/OFF control, memory function, and manual/automatic operation options. An electrical heating controller is available, allowing regulation of heating in 3 stages.

Interface and Centralized Control
An interface box is available for connection to centralized digital management systems such as DDC, PLC, or BMS, enabling direct programming and control of all equipment functions.

Operating control and regulation 5 speed Standard controller. This controller provides a 5-stage speed regulation by voltage modulation totally interference free, motor noises and vibrations free. All connections, both the input and the control, are placed outside the equipment. For a simple connection free of errors, between the controller and the equipment there is used a telephonic type cable with connectors RJ45, what reduces sensibly the installation time. The digital communication with the controller increases the protection against interferences and allows long distances (till 300m) between...
