|As part of its energy review, this global company sought to reduce
its aluminium furnace gas costs. A Gas to Air Superconducting
H/E was selected for the installation.
The project was approved on the basis of a
$100K / year savings and a total cost of $168K.
The superconducting, smooth pipe GA exchanger offers many
benefits in this high particulate exhaust environment which include:
- Low fouling susceptibility – due to smooth,
removed for cleaning
- Ease of maintenance – pipes can be easily
- High reliability – through multiple redundancy design as
each pipe operates independently so that a single pipe
failure (in itself a rare event) will not incapacitate the unit
- Failsafe design – The overall installation design needed to
be failsafe such that production would not be affected in the
event the recovery unit needed to be switched off. To
address this challenge, a design was proposed which
allowed the unit to be by-passed for routine maintenance
using an innovative, cost-effective approach that avoided
the need for costly exhaust diversion valves.
Once in operation, the actual annual saving was 50% higher than
the original estimate!. This excellent result delivered a total
payback period for the project of 13 months. Based on this
success, the client has placed an order for two more systems.

|This client choose an outside pad location, but most are
located as close to the heat source as possible.
|Excessive heat inside the plant was always a problem
so inside air was used as the makeup air for the system
