HRS ParaDice* is a unique offering for dices and ready to eat food processing industry which is capable of processing fruit dices vegetable dices without shearing them. In this cutting edge solution, dices are pumped using HRS Hygienic Piston Pump and are heated and cooled in the highly efficient ECOFLUX* Double Tube Heat Exchangers. The fruit dices can be pasteurised or aseptically processed using the ParaDice*. HRS ParaDice* can be used for processing diced fruits, particulate foods, blanching of vegetables, pasteurisation and chilling of Ready-to-Eat foods, and similar applications.

HRS Process Systems Limited also designs and manufactures ECOFLUX* Smooth Tube Heat Exchanger for various industrial application like heating, cooling, condensing and reboiling in our world class manufacturing facility to cater to Customer's heat transfer requirement. We manufacture units presently to working pressure of 80 bar for process service plant and with 0 temperature upto 400 C. For specific design we can manufacture units with 150 bar pressure at 500 C.Our manufacturing facility is equipped to fabricate STHE with diameter of 2000 mm and tube length upto 9000 mm. For special equipment we can make heat exchanger with 12000 mm tube length. These are customised units based on specific industry application. The units can be fabricated based on customer drawings. We can design and manufacture units to customer specifications too. We design STHE with or without ASME 'U' stamp certification, CE certification and others codes. Heat exchangers are manufactured in Stainless Steel AISI 304/316, depending upon the application. Material like SS304L, SS316L, Hastelloy, Copper, Cu-Ni alloys, Titanium, AL6XN can also be offered.

heat exchanger for difficult and critical processes where other types of heat exchangers such as rotary scraped surface heat exchanger, shell and tube or plain type are incapable of offering an adequate solution. Unicus is capable of generating high levels of turbulence in products of high viscosity increasing substantially the overall heat transfer coefficient. In addition it does not allow the formation of any fouling layers on the inner tube surfaces and always stays clean enabling the unit to work in the optimum condition for efficient heat transfer at all times.

Ecoflux* Corrugated Tube Heat Exchangers (CTHE) use corrugated tubes instead of smooth tubes. The corrugations induce turbulence in the media and ensure high Reynolds number even at low velocity. The development of corrugated tube is perhaps the most exciting advancement in heat transfer technology.

Corrugated tube is produced by indenting a plain tube with a spiral pattern. No tube wall thinning takes place & no strength is lost.

Features

• A smooth indented inner profile ensures easy cleaning
• Turbulence is created at low fluid velocities to enhance the heat transfer in the tube
• Fouling on the tube surface is minimised
• A wide range of diameters & styles are available

Technology:

Corrugated tube is produced by indenting a plain tube with a spiral pattern. This imparts different flow regimes - spiral in the core and eddy's at the periphery.

The helical flow contributes to the situation that the fluid particles are alternatively in the vicinity of the tube wall and then in the main flow. Between the helical impressions, around the circumference of the tube, secondary flow, typically in the form of eddies occur.

The flow regime ensures that the rate of decrease in boundary layer resistance exceeds the rate of increase in pressure loss. In other words high heat transfer coefficients with minimum increase in pressure drop.

Hydrodynamic Thermal Boundary Layer

Increase in heat transfer coefficient brings the temperature of the tube wall closer to the temperature of the bulk fluid on the tube.

The roughness elements need to have a minimum height so as to influence the flow ( Fig. A ) and thus the heat transfer ( Fig. B ). To ensure that the heat transfer is improved by roughness elements, the flow must be influenced within the heat conduction layer.

Advantages:

Corrugated tube shell and tube heat exchangers have many benefits and advantages over comparable smooth tube versions:

• Compact tubular heat exchanger
• Long running times due to turbulent flow
• Very low maintenance costs, minimum spares requirement
• Higher heat transfer coefficient (2-3 times) results in reduction in heat exchanger area upto 50%
• Fouling is minimised due to turbulence created by eddies at the periphery or tube wall
• High response to CIP
• Wide choice of MOC
• Uniform thermal processing
• More flexibility in annular space sizing
