Overview

This document provides detailed technical data for a range of multitubular heat exchangers designed for oil/water cooling applications using untreated water or seawater. The models covered include E065, E083, E110, and E135 series, each available in different configurations and options.

1. Product Description and Application

These multitubular heat exchangers are intended for cooling oil with water, suitable for untreated or seawater sources. They feature a shell-and-tube design with oil/water flowing through the outside tubes and water flowing inside the tubes.

2. Models and Variants

• E065 Series: Available in 2-pass and 4-pass cold side configurations, with maximum water flow rates of 30.6 L/min and 60 L/min respectively.
• E083 Series: Also offered in 2-pass and 4-pass versions, supporting water flow rates up to 150 L/min.
• E110 Series: Available in 2-pass and 4-pass configurations, with maximum water flow rates up to 280 L/min.
• E135 Series: Larger models with 2-pass and 4-pass options, supporting water flow rates up to 460 L/min.

3. Key Technical Specifications

4. Materials and Components

• Tubes and Tube Plates: Brass or copper-based materials.
• Baffles: Anodized aluminium.
• Shell and Cover: Brass or bronze options.
• O-rings: Viton for sealing.
• Options: Drain on hot side, zinc anodes on cold side for corrosion protection.

5. Dimensions and Weight

Dimensions vary by model and configuration, with core lengths ranging approximately from 100 mm to over 500 mm. Weights range from around 2.8 kg for smaller models to over 24 kg for larger units.

6. Options and Accessories

• Drain on Hot Side (D): Facilitates draining of the hot fluid side.
• Zinc Anodes (AA): Two zinc anodes on the cold side for corrosion protection.
• High Flow (H): Option for increased flow on the hot side.
• Material Options: Copper or Copper-Nickel tubes, bronze covers.

7. Performance and Usage Recommendations

The heat exchangers are designed for efficient cooling of oil by water, with untreated or seawater as the cooling medium. Selection of model and configuration should consider maximum flow rates, pressure limits, and temperature requirements. Material options and accessories should be chosen based on the operating environment, especially for corrosion resistance.

8. Summary of Critical Parameters

• Maximum working pressure ranges from 2.8 to 24.2 bar depending on model.
• Maximum water flow rates vary from 30.6 L/min to 460 L/min.
• Tube materials and sealing components are selected to optimize durability and performance.
• Multiple pass configurations allow customization of flow and heat transfer efficiency.
