SPIRAL technology gets BLOCKED,
Max. gap is only 1” and has pins for
other liquid (no % solids there).
- 1“-
TUBE Technology cannot have
same flow for both liquids, and 3”
gap each, at the same time.

Vitalix 65-70 % Solids Molasses

Vitalix Inc. has been using the DDI heat exchanger
almost a year now with very positive results. Raw
molasses at 65% to 70% solids is running on one
side and hot water on the other. We have had no
problems with plugging or pressure build up.
We are also very pleased with the effectiveness of
this unit in heat transfer. Thank you for your help
and support.

• The Pembroke Pollution Control Centre is using the DDI Heat Exchanger with very positive
results. Raw sludge with an average temperature between 11* C to 19* C flows
through one side of the heat exchanger and re-circulated sludge from the
digesters with temperatures ranging in the high thirty’s flows through the opposite side of
the heat exchanger. This has resulted in substantial savings as the raw sludge is
increased in temperature prior to entering the
digesters at no expense to the City sewage
system. After almost two years of operation no plugging has occurred and it works as
