Aluminium Heat Exchanger | A20

Product catalog summary

Overview: This document provides detailed specifications, dimensions, and performance characteristics for the A20 Aluminium Heat Exchanger. It includes information on various models, their electrical and hydraulic configurations, and associated accessories.

Specifications: The A20 heat exchanger is available in different 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 options with thermostatic and pressure bypass valves.

Dimensions: The document provides precise dimensions for each configuration, including the overall size and mounting details. It specifies the dimensions for both electrical and hydraulic actuation models.

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 provided for different oil viscosities and temperatures.

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). Their dimensions and threading specifications are provided.

Accessories: The document lists available accessories, including supporting feet and thermostats with various trigger temperatures. It also specifies thermal switches with IP54 and IP65 protection ratings.

Key Data from Tables: The tables provide detailed model codes, fan specifications, power ratings, and dimensions for each configuration. They also include information on the bypass options and associated performance metrics.
