Technical Specifications
The document provides technical specifications for the HY 140 series of air-oil heat exchangers manufactured by OESSE S.r.l. Key parameters include oil flow, capacity, weight, displacement, motor flow, power, fan diameter, air flow, and noise level. Two models, HY14005 and HY14006, are detailed with specific values for each parameter.

Performance and Efficiency
The performance section includes a graph showing the relationship between oil flow (l/min) and pressure drop (bar), indicating how pressure drop varies with different oil flow rates. Additionally, a viscosity correction table is provided for different oil types (ISO VG @ 40 °C), with correction factors ranging from 0.7 to 2.

Noise and Power Output
The noise level for the HY14005 model is specified at 79 dB(A). The document also provides a conversion for power output, stating that 1 kW equals 860 Kcal/h or 635 HP.
