Features of the WRING-500

AC variable frequency drives as standard equipment on all machines

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

Easy to understand alarm signalization

All motors, proximity sensors, photoeyes and other sensors have quick disconnect cables that simplify installation and maintenance

Photoeyes are maintenance free and protected

All Wulftec structures are made of heavy-duty steel for rugged performance in the harshest work environments

These stretch wrappers are built to last forever

4-legged design for maximum stability at high speed

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 roller blue compound

Preset pre-stretch ratios are available from 50-300%

Angled carriage with very low wrap possibility properly secures the product to the pallet, resulting in stable transport and less damage

No film threading required

Lexan cover eliminates operator's ability to reach rollers when gate is closed

Wulftec's revolutionary drop away clamp ensures clean film release from the pallet load

Non-proprietary parts accessible on a local base

Cut and Wipe System

Pneumatically operated cut and wipe-on system automatically cuts and wipes the film onto the load upon cycle end

First a vertical roller positions the film over the clamp which grabs the film, ensuring 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

Best Warranties in the Industry

3-year unlimited cycle warranty

10-year warranty on steel structure

Lifetime warranty on pre-stretch roller blue compound
