Aluminium Heat Exchanger | A26

Product catalog summary
Overview: This document provides detailed specifications and operational guidelines for the A26 Aluminium Heat Exchanger. It includes dimensions, performance characteristics, and accessory options for various voltage configurations.
Specifications: The A26 heat exchanger is available in multiple configurations, including 12V, 24V, 230V, 400V, and hydraulic actuation. Key dimensions and weights are provided for each configuration, with specific details on fan size, air flow rate, voltage, current, and capacity.
Performance Characteristics: The document includes characteristic curves illustrating the heat exchange capacity, radiator passage pressure drop, and bypass passage load loss under different conditions. These curves are essential for understanding the performance under varying temperature differences and flow rates.
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: A range of accessories is available, including left and right supporting feet and thermostats with various trigger temperatures. The document also details thermal switches with IP54 and IP65 protection ratings, suitable for different environmental conditions.
Recommendations: Users are advised to consult the 'General Instructions for Heat Exchanger Use' before operation to ensure proper handling and maintenance of the equipment.
