Technical Specifications
The document provides technical information on air-oil heat exchangers, specifically the HY 020 model. It includes performance data, oil flow rates, pressure drop, and viscosity correction factors.

Performance
The performance of the heat exchanger is depicted in a graph showing the relationship between oil flow (in liters per minute) and performance (in kW). The performance ranges from 0.04 to 0.24 kW as the oil flow increases from 0 to 150 l/min.

Pressure Drop
Another graph illustrates the pressure drop (in bar) corresponding to the oil flow rates, ranging from 0.1 to 0.8 bar as the oil flow increases from 0 to 150 l/min.

Viscosity Correction
The document provides viscosity correction factors for different oil types (ISO VG @ 40 °C) with multipliers ranging from 0.7 to 2 for oil types 22, 32, 46, 68, and 150.
