Product catalog summary

Inspectable Water-Oil Heat Exchangers Overview
This document provides technical specifications and performance data for inspectable water-oil heat exchangers, specifically the HW 1001_B model by OESSE S.r.l. It includes details on materials, performance metrics, and correction factors for various operational conditions.

Components and Materials
The heat exchangers are composed of several key components: the shell, tubes, tube sheet, heads, baffles, and seals. The materials used include aluminum (Al), copper-nickel (Cu-Ni), brass (Br), OT52, and NBR (Viton) for seals.

Performance and Correction Factors
The document outlines the performance of the heat exchangers in terms of oil flow and efficiency. It provides correction factors for viscosity, temperature, and water flow to adjust performance calculations based on specific conditions:

Viscosity Correction Factor: Varies with oil type (ISO VG @ 40°C) and ranges from 0.7 to 2.
Temperature Correction Factor: Based on the temperature difference (∆T) between oil and water inlet temperatures, ranging from 0.6 to 1.4.
Water Flow Correction Factor: Adjusts for different water flow rates, ranging from 0.2 to 1.

Technical and Dimensional Information
The document provides detailed technical specifications for various models (HW10011B to HW10016B), including:

Performance with Oil (kW): Ranges from 1.7 to 5.5 kW.
Surface Area: Varies from 0.2 to 1.14 m².
Oil and Water Flow Rates: Oil flow ranges from 9 to 90 l/min, and water flow from 6 to 60 l/min.
Capacity and Weight: Oil capacity ranges from 0.5 to 2.9 liters, water capacity from 0.7 to 2.1 liters, and weight from 6 to 12.1 kg.
Dimensions: Provided for each model, including length, width, and height, with specific BSP thread sizes for connections.

Additional Notes
The document includes notes on water and oil discharge points, as well as the inclusion of a zinc anode for corrosion protection.
