U-Turn
U-Turn is a liquid separator especially designed for use with plate heat exchangers in ammonia applications. The module – including the separator and plate heat exchanger ensures minimum pressure drop losses and maximum energy efficiency.
Alfa Laval U-Turn is designed to utilize the very best from Alfa Laval’s plate heat exchanger technology. Installed above, the self-contained U-Turn can be easily mounted onto the compatible plate heat exchanger. It can cover ammonia capacities from 200 to 1400 kW at 0°C evaporation temperature and from 50 to 500 kW at -40°C evaporation temperature.
The module provides an effective and compact installation with less vertical rise and smaller overall dimensions than any other solution.
Main design features
- Compact dimensions
- Shorter height and length allowing installation onsite without dismantling
- No additional support is needed, as the U-Turn separator is supported entirely by the plate heat exchanger
- Easy maintenance, as both sides of the plate heat exchanger are fully accessible.
- All ammonia connections access the same side which makes installation easy
- Integrated oil drain
- Stainless steel ensuring corrosion resistance and no need of surface treatment
Ready to install
The U-Turn module is delivered within short time, due to standardization. It is a fully functional module from one supplier and carries the CE-stamp, as well the approval from PED (Pressure Equipment Directive).
Cómo funciona
El módulo U-Turn abre un nuevo capítulo en la evaporación. Para ver por qué y cómo funciona, lea las características principales y vea nuestro video en la parte inferior de la página.
- Asegura una separación eficiente - debido al uso de cuatro métodos de separación diferentes
- La columna de amoniaco es corta, permitiendo aproximaciones térmicas menores y una alta eficiencia del sistema
- El soporte deslizante permite la expansión térmica, asegurando que no haya tensiones térmicas
- Recipiente de recogida de aceite integrado para operación manual
- Separación basada en tamaño de gota 0,15 mm.
- El margen de separación es un 25% superior al suministrado.
- La velocidad máxima del gas de separación se limita al 60% de la velocidad de arrastre, evitando el retorno del líquido al flujo de gas.
- Margen de seguridad extra de por la U en 180º
