Wulftec was the first in North America to put AC variable frequency drives as standard equipment on all machines. Why? Lower maintenance and better reliability—Wulftec stretch wrappers will save time and money
NEMA 4/12 control panel dust tight and waterproof
The control panel is neatly organized eliminating time otherwise lost searching for wires
The control panel is UL508A approved
Superior Electrical/Electronic Design including Allen Bradley MicroLogix PLC and AC drives
User friendly touch screen offers a simple yet effective way to adjust and maintain your equipment
All motors, proximity sensors, photoeyes and other sensors have quick disconnect cables that simplify installation and maintenance
All Wulftec structures are made of heavy-duty steel for rugged performance, even in the harshest work environments. They’re built to last forever
Robust 3-legged design for optimal stability and less stress on the frame
A 25″ ring gear with pinion gear drive provides the strongest drive in the industry and is warranteed for 10 years.
Dual chain driven for balanced movement & no vibration
Our heavy duty conveyors are second to none in the industry
The “Maintenance Free” spring loaded carriage gate equipped with spring loaded rollers, ensures optimal contact with the stretch film year after year, without involving maintenance
Wulftec is the only manufacturer to offer a LIFETIME warranty on its pre-stretch rollers’ blue compound.
Preset pre-stretch ratios are available from 50-300%
The angled carriage with very low wrap possibility, the product is properly secured to the pallet, resulting in a pallet that is more stable for transport, and therefore less damage
No film threading is required and a Lexan cover eliminates operator’s ability to reach rollers when gate is closed
The pneumatically operated cut and wipe-on system automatically cuts and wipes the film onto the load upon cycle end
A vertical roller positions the film over the clamp which grabs the film; this ensures longer heat wire life expectancy
Then the heat wire swings in and cuts the film
A timed impulse heat control, allows quick cool down so the heat wire becomes cold to the touch within 5 seconds
Wulftec’s revolutionary drop away clamp ensures clean film release from the pallet load
Benefit from our splash proof program with the top cover pause
Non-Proprietary parts accessible on a local base
