4. CORRUGATED TUBE HEAT EXCHANGERS • HRS Heat Exchangers applies corrugated tubes in the heat exchangers it manufactures. Corrugated tubes heat exchangers provide interesting advantages compared to smooth tube heat exchangers: • Corrugation disrupts the boundary layer near the tube wall. • Corrugation introduces extra turbulence. • Extra turbulence means less fouling. • Corrugation increases heat transfer. • Corrugated tubes allows for more economic designs.

5. MULTI TUBULAR HEAT EXCHANGERS

6. PASTEURIZATION: MX SERIES • The MX series is developed especially for food and pasteurization applications. It is designed with a removable tube bundle. This allows for product to product heat recovery. The compact header design makes it possible to fit a lot of heat transfer area in a very small space: • Features: • Compact header design, easy maintenance. • Removable tube bundle. • Corrugated tubes. • Heating / cooling / product to product heat transfer. • High degrees of energy recovery. • Small footprint.

8. OTHER TUBULAR HEAT EXCHANGERS

9. UNICUS: DYNAMIC SCRAPED SURFACE HEAT EXCHANGER • HRS Heat Exchangers has developed the Unicus for applications where corrugated tubular heat exchangers can no longer perform: • High fouling applications. • Very viscous fluids. • For these applications it is necessary to keep the heat transfer surface clean at all times. Also it is important to mix the fluid and increase the heat transfer. This is exactly what the Unicus does. • The Unicus is a dynamic scraped surface heat exchanger. It outperforms normal shell and tube heat exchangers, works fouling free and has high heat transfer rates. The Unicus can work with delicate products (food industry) and big particles, without damaging the products integrity.

10. UNICUS: DYNAMIC SCRAPED SURFACE HEAT EXCHANGER The Unicus is a shell and tube exchanger. Each interior tube contains a scraped bar with scraper elements. The reciprocal movement of the scraped bar mixes the fluid and keeps heat transfer rates high. The scraper bars are moved by means of a hydraulic drive or pneumatic drive system. The scrapers continuously clean the tube wall and remove any formation of fouling layers. Zero fouling means that shutdowns for heat exchanger cleaning reduced. Less downtime results in a more economic operation. Various types of scraper elements can be fitted. The scraper type depends on the type of application and product.

11. UNICUS: DYNAMIC SCRAPED SURFACE HEAT EXCHANGER • U SERIES • Food grade and industrial design. • Materials: AISI 304 / 316L. • Area: 0,7 to 10 m2 (Food grade models). • up to 100 m2 (Evaporator models). • Applications: • Condensation. • Heating / cooling. • Evaporation. • Medium to high viscosities. • Big particle size. Industries: • Food industry. • (Petro) chemical. • Environmental. • Biomass. • Pulp and paper.

12. PLATE HEAT EXCHANGERS The plate heat exchanger consists of a series of heat transfer plates (separated between gaskets) which are fixed between a fixed plate and a pressure plate. The plate heat exchanger contains a lot of heat transfer area in a very small space. Each plate has a corrugate profile for increasing heat transfer. The plate heat exchanger is an economic solution for no fouling applications with low viscosity products.

13. PLATE HEAT EXCHANGERS • PHE SERIES • Industrial design. • Materials: AISI 304 / 316L. • Area: 0,1 to 1400 m2. • Applications: • Steam. • Water. • Heating / cooling. • Low viscosities. Industries: • (Petro) chemical. • Heating and ventilation (HVAC). • (Waste) water. • Heat recovery.

14. EVAPORATORS HRS Heat Exchangers applies the corrugated tube heat exchangers and the Unicus scraped surface heat exchanger as evaporators. The corrugated tube heat exchangers are applied for low viscosity evaporation without fouling. The Unicus evaporators are applied for concentrating to high dry matter contents. In these cases fouling and high viscosities are often a problem. HRS Heat Exchangers applies these evaporators in a forced recirculation setup. Multi effect evaporation and evaporation with mechanical vapor recompression can be applied.

15. PISTON PUMP HRS Heat Exchangers has developed a positive displacement piston pump for applications closely related to Unicus applications: delicate and viscous food products. The piston pump is able to pump food stuff with large particulates without damaging the structure of the product. In many occasions the piston pump and the Unicus are applied for offering the best solution for pumping and heat treatment of food products.

16. PISTON PUMP • BP SERIES • Food grade design. • Materials: AISI 304 / 316L. • Flow rates: 1 to 12 m3/hr. • Pressures: up to 30 bar. • Applications: • Food products. • Big particles. Industries: • Food industry

17. DESIGN Thermal design: HRS Heat Exchangers uses in house developed software for the design of its heat exchangers. The program contains special developed correlations for the corrugated tube heat exchangers and the scraped surface heat exchangers. Mechanical design: HRS Heat Exchanger can design to the following mechanical design codes: PD5500 AD2000 Merkblätter ASME
