NEW FEATURE: Comparing DDI “Cube” or “Square” Heat Recovery to competition. Since DDI’s Heat Recovery System has a Minimum Gap of 2.75" on both sides (to avoid blockage) it makes no difference which side has Water or Sludge, or even both sides could have Sludge (for Heat Recovery). We achieved our NON-PLUG design (compared to the Spiral design) via large GAPS, NO OBSTACLES and ROUND CURVES. DDI has achieved the possibility of having THE SAME FLOW in both sides (for Heat Recovery), compared to Tube and Shell exchangers which cannot do it (see the SURFACE Heat Transfer area and FLOW area Comparisons). DDI’s overall size is SMALLER then the Tube and Shell and does not require Grinders or Macerators (adds 200,000$ in 10 years) as the Spiral design does. We have had 12 Engineers working for many years to come up with this design and to TEST it in real life with working units. Our MissionTo provide high quality Heat Exchangers with our unique, efficient,
non-pluggable design.
Company ProfileDDI was founded in 1980 and has been providing quality service and reliable solutions ever since. DDI is a well established Canadian company experienced in the design and manufacturing of plate type heat exchangers specifically suitable for applications in heat recovery from liquid waste materials containing large size solids such as municipal sludges and many other processes.
