System provides high pressure tube solution
Conex Bänninger, in partnership with
Wieland K65 tubes, has developed
K65 fittings for the commercial sector,
as a solution for high pressure ACR
applications. Conex Bänninger CO2
solutions can deliver pressure ratings up
to 120 bar (1,740 psi). The K65 system
also enables businesses to retain their
green credentials by using the highly
pressured CO2 R744 refrigerant.
Suited to a range of highly pressured
refrigeration and air conditioning
applications, such as installations in
office blocks, high rise apartments,
schools and supermarkets, the K65
system simplifies specification as there
is no tube gauge variation in Wieland’s
alloys and Conex Bänninger’s
complementary fittings range.
With installer safety of paramount
importance, both the tube and fitting
components of the K65 system are
UL 207 certified. The K65 range’s
processing properties, similar to those
of copper, mean that the fittings can
be easily brazed to the tubing without
the need for expensive or special
equipment.
The thermal conductivity of K65
enables heat to be transmitted
through the pipe with improved energy
efficiency – claimed to be higher
by a factor of 20 compared to its
stainless steel counterparts. Its high
mechanical strength means that it can
be manufactured economically and at
a lighter weight compared to some
alternative materials.
Bill Barlow, Conex Bänninger’s UK
sales director for OEM and ACR,
commented, “At Conex Bänninger we
recognise the significant rise in demand
for highly pressurised CO2 solutions
within commercial refrigeration and air
conditioning. To this end, the K65 system
offers a best-in-class system. The
product not only delivers outstanding
pressure withstanding performance of
up to 120 bar (1,740 psi), but is also an
environmentally friendly solution.”
Conex Bänninger K65 fittings are easily
identified by the manufacturer’s mark,
as well as the K65 mark and 120 bar
(1,740 psi) pressure rating. In addition,
the material is slightly magnetic and
can be easily distinguished from copper
by means of a neodymium magnet,
providing a practical advantage for
installers and system builders.
