Technical Specifications:
The document provides technical specifications for the HY 160 series of air-oil heat exchangers manufactured by OESSE S.r.l. Key parameters include oil flow rates ranging from 100 to 400 liters per minute, with specific models like HY16005 and HY16006 having different weights and capacities. The fan diameter is 680 mm, and the noise level for the HY16005 model is 82 dB(A).

Performance and Efficiency:
The performance of the heat exchangers is measured in terms of pressure drop and efficiency. The pressure drop is depicted in a graph showing a relationship with oil flow rates, and viscosity correction factors are provided for different oil types (ISO VG @ 40 °C). The performance graph indicates efficiency in kW, with a conversion factor of 1 kW equating to 860 Kcal/h.

Viscosity Correction:
Viscosity correction factors are provided for various oil viscosities, ranging from 0.7 for ISO VG 22 to 2 for ISO VG 150, indicating how the performance metrics should be adjusted based on oil viscosity.
