Aluminium Heat Exchanger | A75

Product catalog summary

Overview: This document provides detailed specifications, dimensions, and performance characteristics for the Aluminium Heat Exchanger A75. It includes information on various models, their electrical and hydraulic configurations, and associated accessories.

Specifications: The A75 heat exchanger is available in multiple configurations, including 12V, 24V, 230V, and 400V models. Key specifications include fan dimensions, air flow rates, voltage, current, and weight. The document lists several models with different bypass settings and pressure ratings.

Dimensions: Detailed dimensions are provided for each model, including the overall size and specific measurements for installation. The document specifies that support feet are not included and must be purchased separately.

Performance Characteristics: The document includes characteristic curves illustrating the heat exchange capacity, radiator passage pressure drop, and bypass passage load loss under various conditions. These curves are essential for understanding the performance under different operational scenarios.

Bypass Valves: Two types of bypass valves are detailed: the thermostatic T15 VT (3 bar, 60°C) and the pressure T15 VNR (4.5 bar). These valves are critical for maintaining optimal performance and safety.

Accessories: The document lists available accessories, including left and right supporting feet and thermostats with various trigger temperatures. It also details thermal switches with IP54 and IP65 protection ratings, providing additional safety and operational control.

Legend: A legend is provided to explain the abbreviations used in the document, such as A75 for the exchanger type, and various codes for fan unit configurations and bypass valve types.
