1. General Specifications
The document provides technical data for multitubular heat exchangers used for cooling oil/water with untreated or sea water. The models covered include A065, A083, A104, A120, and A178. Each model has specific configurations for core diameter, core length, and number of passes on the cold side.
2. Materials and Construction
Materials used in construction include CuNi10Fe for tubes, CuZn39Pb2 for tube plates, CuZn36 anodized for baffles, aluminum for shells, CuSn7Pb6Zn4 for covers, and Viton for O-rings.
3. Model-Specific Data
- A065: Maximum water flow rate of 30.6 L/min, hot side connection G 3/4", cold side G 1/2".
- A083: Maximum water flow rate of 69 L/min, hot side connection G 1" 1/2, cold side G 3/4".
- A104: Maximum water flow rate of 94 L/min, hot side connection G 1" 1/2, cold side G 1".
- A120: Maximum water flow rate of 168 L/min, hot side connection G 1" 1/2, cold side G 1".
- A178: Maximum water flow rate of 380 L/min, hot side connection G 2", cold side G 1" 1/2.
4. Performance Characteristics
Each model has specific working characteristics including maximum working pressure and temperature. The document provides detailed dimensions, volume, and weight for each model.
5. Design and Geometry
The heat exchangers are designed with specific geometries to optimize flow on both hot and cold sides. Options for standard and high flow configurations are available.
6. Additional Features
Some models include a drain on the hot side for maintenance and operational efficiency.
Conclusion
This document serves as a comprehensive guide for selecting and understanding the specifications of multitubular heat exchangers for industrial cooling applications.
