New Brazed Heat Exchangers
 |
Brazed Plate Heat Exchangers work on the same principle
as conventional plate heat exchangers, but consists of
a pack of corrugated plates joined together and sealed
by vacuum furnace brazing. Typically the units are copper
brazed, however for those applications where the medium
is aggressive to copper or where temperatures range from
225°C to 400°C, then nickel is used. The plates
are manufactured as standard from high-grade AISI 316
acid resistant steel with a thickness of either 0.35mm
or 0.4mm dependent on the model type. A specially designed
chevron pattern causes a turbulent flow of the fluid resulting
in higher heat transfer and a reduction in heat exchanger
fowling. |
TYPICAL APPLICATIONS
Brazed plate heat exchangers are designed for a wide range of
applications within the process, marine and industrial cooling
applications such as, beverage coolers, co-generation systems,
de-ionized water systems, hydraulic oil coolers, lube oil coolers
and onboard coolers and heaters. This type of heat exchanger
is also widely used for refrigeration applications such as evaporators,
condensers and sub-coolers.
ADVANTAGES OF THE BRAZED HEAT EXCHANGER
Compact:
Due to the high efficiency of the brazed plate heat exchangers,
these heat exchangers are often 25% the size of a conventional
shell & tube heat exchangers. The smaller footprint also
makes it easier to be installed on skid systems and portable
equipment packages.
High Efficiency:
Due to the turbulent flow of the fluid in the channels, the
heat transfer coefficients of brazed plate heat exchangers
are 3-5 times higher than that of a conventional Shell &
Tube heat exchanger for a similar application.
Low-Maintenance:
The 316SS construction of brazed plate heat exchangers provides
superior corrosion resistance, and fouling is virtually eliminated
by the self-cleaning effect generated through high- induced
turbulence.
Rugged Construction:
The brazed plate heat exchanger is brazed using 99.9% copper.
The copper provides a strong bond when heated in a special
vacuum furnace, keeping the plates bonded together. The heat
exchangers have a high pressure-temperature rating
Cost Effective:
Very low investment and quick pay pack period.
