Nexus - Scraped Surface Heat Exchangers
Nexus is a compact, high-capacity, high-pressure scraped surface heat exchanger designed for various high-viscosity applications within the Fats & Oils industry. It is designed for low energy consumption using CO2 as the highly efficient cooling medium, but it can also be used with the traditional ammonia NH3. It provides high crystallization performance, minimal downtime, and easy maintenance.
FEATURES
Benefits
- Multi-purpose machine for all edible Fats & Oils (F&O) products.
- Hygienic design suitable for the food industry.
- All product contacting parts are made in stainless steel AISI 316 or better.
- Completely sealed, fully insulated, corrosion-free stainless steel casing guarantees years of trouble-free operation.
- Special, corrugated multi-layer chromed chilling tubes for improved heat transmission value.
- The chilling tubes can easily be inspected and replaced.
- Optional rotor systems with scrapers in a selection of different materials depending on the application.
- Low energy production of crystallized fat products. Test results show that using CO2 at -10°C reduces energy consumption in the refrigeration system by up to 30% compared to an ammonia compressor at -20°C.
- Reduction in heat transfer costs. CO2 is a very efficient refrigerant which has an external heat transfer coefficient which is2-3 times higher than that of ammonia and which will increase the total heat flux by up to 40%.
- Heat recovery system possible. When using CO2 as the refrigerant, it is possible to install and use heat recovery systems to save energy. The heat recovery can offer useable water at up to 90°C, which can be used elsewhere in the plant. Up to 70% of the energy can be recovered.
- CO2 as refrigerant provides lower investment costs for CO2 refrigeration system compared with ammonia.
- Minimum downtime as CIP cycles are fast and efficient, and maintenance procedures are simple.
- The low energy motors and the cast iron gear boxes yield maximum power while keeping noise levels to a minimum.
- Small footprint which optimizes the floor space and the piping requirements.
