Aluminium Heat Exchanger | A83

Product catalog summary

Overview: This document provides detailed specifications and operational guidelines for the Aluminium Heat Exchanger A83. It includes dimensions, performance characteristics, and component descriptions for various configurations and voltage options.

Specifications: The heat exchanger is available in multiple configurations, including 12V, 24V, 230V, 400V, and hydraulic actuation models. Key specifications include fan diameter, air flow rate, voltage, current, and weight. The document lists specific models with their respective performance metrics such as bypass pressure and thermal capacity.

Dimensions: Detailed dimensions are provided for each model, including tolerances. The document specifies the layout for 12V-24V, 230V-400V, and hydraulic actuation models, highlighting critical measurements for installation and integration.

Performance Curves: The document includes characteristic curves illustrating 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 described: the thermostatic T15 VT (3 bar, 60°C) and the pressure T15 VNR (4.5 bar). These components are crucial for maintaining optimal flow and pressure conditions within the system.

Accessories: The document lists available thermostats and thermal switches with their trigger temperatures and threading codes. These accessories are designed to enhance the functionality and safety of the heat exchanger system.

Legend: A legend is provided to decode the model codes, explaining terms like aspirating, blowing, and various power levels (e.g., high power, extra high power).
