Technical Specifications:
The document provides technical data for air-oil heat exchangers, specifically the HY 020 model. It includes performance metrics such as oil flow rates and pressure drops. The performance is measured in kW, with conversions provided (1 kW = 860 Kcal/h and 1 kW = 635 HP).

Performance and Flow Rates:
The performance graph indicates oil flow rates ranging from 0 to 150 liters per minute, with corresponding performance values from 0.04 to 0.24. The pressure drop is also charted against oil flow, showing values from 0 to 0.8 bar.

Viscosity Correction:
Viscosity correction factors are provided for different oil types (ISO VG @ 40 °C), with multiplication factors ranging from 0.7 to 2 for oils with viscosities of 22, 32, 46, 68, and 150.

Product Specifications:
The document lists specifications for two models, HY02001 and HY02003, detailing oil flow capacity (30 - 120 l/min), weight (9.3 kg), voltage (230 V or 230/400 V), frequency (50/60 Hz), current (0.39 to 0.56 A), power consumption (90 to 130 W), fan diameter (250 mm), air flow (1100 m3/h), and noise level (70 dB(A)).
