The OFENBAU FRITZ furnaces are distinguished, among other things, by their low energy
consumption. The continuous wire annealing furnace system ‘Becker-Fritz’ is the most
economic furnace of its type, with a consumption of ~150.000-190.000kcal/t of
production. All the heat is given to the wires; the waste gases enter the chimney with
only ~250°C. The heating equipment, even on the bigger furnaces, encompasses only
3-4 burners (= low-cost regulation and control).
By comparing consumption data, the amount of energy that may be saved can be estimated.
Assuming 170.000kcal/t for the ‘Becker-Fritz’ furnace and 220.000kcal/t for the other annealing
furnace, on a plant with an output of 3t/h, 7.200 working hours per year
= 50.000kcal saved per ton of produced wire
= 150.000kcal saved each hour
= 1.080.000.000kcal saved during one year
This corresponds to ~100.000kg of natural gas or 1.200.000kwh.
OFENBAU FRITZ has supplied this type of furnace for 50 wires and an output of 6.000kg/h. Individual
channels allow producing low carbon wires of di erent tensile strengths in one furnace (~40kg/mm²
and 60-70kg/mm², also supplied for ~40kg/mm² and 90 100kg/mm²). By adopting the required wire
height and pitch, the furnace can be installed in existing lines.

A very economic wire annealing furnace
The Triple Twist process, a Gauder Group
patented solution since 2001, allows
40-50 per cent higher production speed
from lower investment while offering
improved cable quality compared with
conventional LAN pairing lines. It is the
best industry standard for Cat 5/6/7 LAN
cable production.
With some 200 Triple Twist twinning lines
sold, Setic, a member of the Gauder Group,
remains the leader in the LAN cable pairing
field. Thousands of kilometres of cable have
been manufactured on these machines in
the major LAN cable manufacturers’ plants
worldwide.
Setic equipment offers all the benefits
of backtwist technology, combined with
the advantages of the world-famous
‘DVD 560’ (twin vertical double backtwist
pay-off ): stabilised impedance and
superior consistency, hydraulic loading
platform and pneumatic pintles for easy
reel handling, continuous adjustment
of backtwist rate from the operator’s
control panel, integrated electrical
cabinet, and stand alone equipment.
The range includes the vertical ‘all-in-one’
Triple Twist pairing machine type ‘VTT
560’ enabling the production of Cat 5E
pairs around 6,300 TPM (instead of 4,500
TPM on standard 560mm Double Twist
twinner) and Cat 6 pairs at 6,000 TPM
for (instead of 4,000 TPM on standard
560mm Double Twist twinner).
The same production result can be
achieved by using double position
pay-off for Triple Twist process type
‘DVD TT 560 R’ or ‘DHD TT 560’ located
before an existing standard Double Twist
machine.
It increases running speed of 1,500 up to
2,200 TPM and allows production from
Cat 5 up to Cat 7, as well as being able to
use the twinner for other products types.
Setic also placed the Triple Twist pairing
process on a one-step machine creating
the ‘G3T 560’ model for twinning in one
operation 4 (or ‘n’ as an option) pairs Cat
5/5E/6E and 7/8 from insulated wires, on
the same line, speeding up to 6,000 TPM.
