The Ultraseal
®
20 is
a compact and light-
weight ergonomic
system which is easy
to use and low cost to operate.
The Branson Ultraseal
®
20 is a
rigid, lightweight and ergonomic metal
joining system able to seal metal tubes
from 4 mm capillary up to 12 mm diam-
eter. It is easily operated directly on the
charge line, supported by a balancer,
or as a bench top unit to reliably seal
pressurized charge tubes.
Environmentally friendly, the
Ultraseal
®
20 requires no stored
energy, minimal energy at 'standby -
weld ready' and, with a stack efficiency
of approximately 95%, delivers the
lowest total operating cost over life
of ownership.
The Ultraseal
®
20 mechanically crimps
the tube closed and vibrates the inner
surfaces together at 20,000 cycles per
second. The intense scrubbing action
mixes the molecules forming a metal-
lurgical bond ensuring a hermetic seal.
MODES OF OPERATION:
Pre-Height Search: A pre-sonic
crimp measurement instantly scans
and automatically activates the opti-
mum weld parameters from the
controller's memory sealing the tube.
This is used when tube size and/or
hardness varies within a production
line to produce repeatable and reli-
able welds.
Proximity Sensor: The ultrasonic
generator delivers high frequency
vibratory energy sealing the tube
to the preset final seal height. This
is used when the tube size and
hardness does not vary producing a
repeatable and reliable seal.
Explosion Proof Ultraseal
®
20EX:
Independently lab certified for use
with isobutene refrigerants. A safety
purge system removes potentially
trapped gas from the weld actuator
prior to electrical startup and
remains continuously active while
powered up, eliminating the
potential of gas accumulation.
