Aluminium Heat Exchanger | A22

Product catalog summary

Overview: This document provides detailed specifications, dimensions, and performance characteristics for the A22 Aluminium Heat Exchanger. It includes information on various models, their electrical and hydraulic configurations, and associated accessories.

Specifications: The A22 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 valves used, including thermostatic and pressure bypass types.

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 showing 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.

Accessories: Accessories such as supporting feet and thermostats are detailed, including their dimensions and trigger temperatures. The document lists codes for ordering these accessories.

Key Data from Tables and Graphs: - Air flow rates range from 920 to 1100 m³/h for 12V and 24V models. - Pressure drop and heat exchange capacity are illustrated for different flow rates and temperatures. - Bypass valves operate at 3 bar and 4.5 bar, with specific temperature settings.

Recommendations: Users are advised to refer to the 'GENERAL INSTRUCTIONS FOR HEAT EXCHANGER USE' before operating the heat exchanger. Proper selection of bypass valves and accessories is crucial for optimal performance.
