HRS DTI - Double Tube Corrugated Heat Exchangers used in environmental applications .
And this is where Unicus and R series scraped surface heat exchangers come into play once again , as they are ideal for evaporation applications ; Unicus for larger jobs , and R series for smaller ones . Along with evaporation , the R series can also be effectively used in crystallisation processes to achieve Zero Liquid Discharge ( ZLD ). “ Sometimes , if the solid that is dissolved in the wastewater has value , the customer will want to recover that , so we combine an evaporation plant with the crystallisation plant ,” explains Arnold . “ We deal with wastewater from all sorts of industries : from agriculture and the processing industry to the oil and gas industry .” Scraped surface heat exchangers have a crucial role to play in ZLD systems in reducing running costs by utilising heat from process water and other existing sources , and recapturing heat at the end of the process and reusing it to boost the energy efficiency of the overall ZLD system . In addition , HRS helps its customers deal with their wastewater locally and detect what sort of added-value product can be recovered from it .

Custom solutions Building a loyal and satisfied customer base requires a tailored approach to each problem . “ Everything we do is custom-built ,” begins Matt . “ We have no standard one-size-fits-all system . We build everything based on a customer ’ s requirement , rather than offering them separate components or spares . We ’ re not a component seller . We ’ re a heat exchange solution supplier .” HRS pride themselves on building applications that fit their customers ’ needs instead of offering something that ’ s too big or too small for their requirements and forcing them to make it work . Given the wide ranging number of tubes they can fit in one heat exchanger , every client is guaranteed to receive a customised solution specifically based on the materials they deal with . To handle salts and corrosion that accumulate from highly viscous materials , the company applies higher alloys in these applications , including duplex , super duplex , titanium , and more .
