Aluminium Heat Exchanger | A48

Product catalog summary

Overview: This document provides detailed specifications, dimensions, and performance characteristics for the Aluminium Heat Exchanger A48. It includes information on various models, their electrical and hydraulic configurations, and associated accessories.

Specifications: The heat exchanger is available in multiple configurations based on voltage (12V, 24V, 230V, 400V) and fan types (aspirating, blowing, high power). Key specifications include fan diameter, air flow rate, voltage, current, and weight. The document also details the bypass valves used, including thermostatic and pressure bypass types.

Dimensions: The document provides precise measurements for each model, including overall dimensions and specific component sizes. It highlights the importance of consulting the 'General Instructions for Heat Exchanger Use' before installation.

Performance Curves: Graphs illustrate 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 temperature and flow rate scenarios.

Bypass Valves: Two types of bypass valves are used: T15 VT (thermostatic, 3 bar, 60°C) and T15 VNR (pressure, 4.5 bar). These 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.

Key Considerations: The document emphasizes the importance of selecting the correct model based on specific application requirements, including voltage, fan type, and bypass valve configuration. Proper installation and adherence to the general instructions are crucial for optimal performance and longevity.
