ALFA EC

Product catalog summary

Overview: The document provides comprehensive technical specifications and operational guidelines for the ALFA EC and AHAL ventilation units, designed for commercial environments such as offices, shops, and sports facilities. These units are optimized for efficient air ventilation and heating.

Specifications:

Available in six sizes with airflow capacities up to 10,000 m3/h.
Equipped with energy-efficient EC fans for low specific fan power (SFP) and quiet operation.
Includes integrated electric or water after-heaters, with options for modular change-over (C/O) or direct expansion (DX) coils.
Designed for low installation height, suitable for suspended ceilings.
Constructed with sandwich panels and a silver-painted exterior.

Operating Conditions:

Intended for indoor use in dry environments with ambient temperatures between +5°C and +35°C, and relative humidity up to 80%.
Capable of handling air free from rough dust, grease, and chemical fumes, with temperatures ranging from -30°C to +40°C and relative humidity up to 90%.
Features an IP20 protection rating when installed in a duct system.

Control and Maintenance:

Features a sophisticated integrated control system with a touch controller for intuitive operation.
Allows control of air capacity in five levels, air heating, flap adjustments, and identification of failure conditions.
Emphasizes simple maintenance and easy installation.

Performance Characteristics:

Performance is characterized with filter class Coarse 90% (G4).
Various models are available with different heating options, including electric heaters with temperature differentials (ΔT) of 10°C to 40°C, and hot water heaters.

Graphical Data:

Includes performance graphs showing the relationship between air flow (m3/h) and pressure (Pa) for different models and configurations.

Design and Development:

Projects involving these ventilation units should be developed by HVAC designers to ensure optimal performance and integration.

Installation and Assembly: Units are designed for horizontal installation with inspection covers facing upwards or downwards. Proper installation must ensure sufficient access for maintenance and servicing. Flammable materials must be kept at a safe distance from the unit.

Control System: The AirGENIO SUPERIOR control system allows for remote adjustment of operational parameters and alarm display. It supports various control modes including CO2 concentration, CAV, VAV, DCV systems, and features like night ventilation, boost mode, and fire protection mode.

Noise Data: Indicative sound pressure levels at a distance of 3m are provided for different unit types, detailing frequency bands and total sound power levels.

Accessories: Required accessories for functionality are listed, with specific configurations for different unit types. Some combinations are not allowed in the EU zone.

Main Sections:

1. Specifications: The document outlines various specifications for ventilation units, including nominal air flow rates ranging from 500 m3/h to 8000 m3/h. It also details different configurations such as electric heaters and LPHW coils.

2. Procedures: The document includes information on input and output connections for various components like the main electric supply, pressostat, air quality sensor, and external control systems.

3. Standards and Recommendations: The document provides coding keys for identifying different models and configurations of the ALFA ventilation units, indicating features like electric heating and control systems.

4. Key Components: The document lists components such as the main power supply, remote control, extract unit, and PC RS232/485 connections, along with their respective input and output specifications.
