Environmental technology is a widely used term nowadays. Behind this are concealed
technical and technological developments whose employment protect our environment
or offer the chance to regenerate it. We also make our contribution here in
different areas.

Typical tasks for SIGMA plate heat exchanger in metal
processing are:
- Cooling of waste-dump percolation water
- Heat recovery

Application example: Cooling of waste-dump percolation water
We received an order from a municipal refuse collecting firm for the delivery
of plate heat exchangers, including replacement plate packages in 1.4539. With
our plate heat exchanger, extreme sludge-content waste-dump percolation water
is cooled before biological preparation treatment. An operational durability
of 9 - 12 months, without intermediate opening of the equipment, was required
by the customer. Up to now the equipment has been opened only once for inspection.
The dirt accumulation was so slight that the plate heat exchanger could be
started again immediately afterwards.
Application example: Plate heat exchanger for wash water
Our company received an order for a total of eight plate heat exchangers in
titanium material. In each case, four units serve as regenerative
exchangers for the pre-warming of cold alkalized waste water using hot waste
water. The heat recovery in the exchangers is 90%. The alkalized waste water
comes from the washing system of a garbage-collecting unit. According to a
new ordinance, the plastic garbage must be cleaned of contamination and food
residue before combustion. The waste water results from this cleaning. |
