Tubular Heat Exchanger

This vertical tubular heat exchanger is engineered for efficient, controlled heat transfer in steam and vapour applications, making it well-suited for dairy and liquid processing environments. Designed and constructed to ASME VIII, Div. 1 (2007) standards, it offers a reliable and safe solution for demanding industrial processes.

The system facilitates effective heat exchange between water in the shell and steam or milk vapour flowing through the tubes. This configuration ensures consistent temperature regulation, supporting product quality while maintaining process efficiency across continuous operations.

Its vertical design allows for a compact footprint and efficient integration into existing processing systems. Built for durability and performance, the unit is ideal for applications requiring stable thermal control and dependable operation.

Sizing interpretation

With KALT / Flotech units, the model D51-1208S usually indicates:

• D51 = exchanger series / shell diameter class
• 1208 = tube bundle length / configuration
• S = sanitary configuration

Based on similar KALT shell-and-tube exchangers, the approximate size would likely be:

Estimated dimensions

• Shell diameter: 150–200 mm
• Overall length: 1.5–2.0 m
• Connection size: 40–50 mm
• Heat transfer area: approximately 1.5–3.0 m²
