TUNNEL OPTIMIZATION

We don't just support your tunnel. We engineer its performance.

Tunnel washers are high-stakes systems where precision chemistry and process design determine throughput, quality, and the life of expensive equipment. WSI brings deep, field-based tunnel expertise to operations on every major manufacturer — and the measurable results to prove it.

People + Process = Performance

Great tunnel performance isn't a product you buy — it's a system you engineer. WSI pairs experienced specialists with a disciplined process to get more out of the tunnel you already own.

What sets WSI apart:

WSI tunnel specialist servicing equipment on the wash aisle

OEM-agnostic expertise — we optimize across all major tunnel manufacturers, not just one platform

A nationwide team of tunnel specialists, strategically positioned to be on-site where you operate

Conventional-quality results — a properly set tunnel can match the wash quality of conventional washers

Outcome-focused, not product-heavy — we measure success in throughput, quality, and cost control

One-Pass Processing — for laundries that require it, WSI can build a program around this process

We measure success the way you do — in throughput, quality, and cost control.

A structured methodology — not guesswork

Every engagement follows a repeatable framework built on WSI's real consulting and training approach.

Assessment & Diagnostics

We measure what's actually happening: flow rates, transfer times, load weights, and the mechanical components that drive performance — weirs, reuse systems, and more.

Process Engineering

We design sequencing and scheduling around your plant's mix, and build clear operator flow charts so the right process runs every shift.

System Optimization

We tune water levels, reuse temperatures, and overflow settings to eliminate inefficiencies built up over years of operation.

Training & Enablement

We train operators and maintenance teams so gains hold — performance shouldn't depend on one person being on shift.

Continuous Improvement

We monitor, follow up, and keep tuning as your volume and mix change.

Proven on the wash aisle

Real results from real plants — in Problem → Solution → Result format.

Throughput Optimization

Excess purges and pass-empties were dragging down throughput and utilities.

Solution: WSI re-sequenced the process and corrected transfer timing.

Result: Higher throughput and lower utility usage from the same tunnel — supporting more output per labor hour.

Legacy Tunnel Optimization

An older tunnel was underperforming against current quality standards.

Solution: WSI adjusted flow rates and transfer times, customized to the plant's loads.

Result: Restored consistent quality without new capital equipment.

Water & Reuse Efficiency

Reuse tank overflow and temperature settings were wasting recovered water.

Solution: WSI corrected overflow and reuse-temperature settings.

Result: Reduced waste and improved reuse efficiency.

Flagship Innovation

TRU-UV: The New Standard for Tunnel Hygiene & Performance

Confidence you can measure. See the clean.

TRU-UV is the innovation layer chemical-only competitors don't have. It sends UV-treated water into the wash and/or bleach zones of your tunnel — not just the rinse — so you can run no chlorine bleach, lower wash temperatures, and peroxide-only chemistry, with no ozone or hydroxyl gas.

UnknownUV-Validated Clean

UV-validated hygiene you can prove — not assume.

Proof of Clean

UV validation gives you visible verification of hygienic performance. No more relying on assumption.

Microbial Reduction

Verified 7-log reduction of organisms, producing hygienically clean textiles.

Integrated with Your Tunnel

TRU-UV runs continuously with the tunnel, enhancing the wash environment in real time rather than bolting on a separate step.

Performance & Quality Gains

Improved whiteness, reduced rewash, and biofilm removal across the tunnel and reuse tanks.

Efficiency Improvements

Lower wash temperatures (a 10–20°F reduction; preferred range 125–140°F), reduced chemical dependency, and the elimination of chlorine bleach and PAA as oxidizers. Where plants run bath exchanges, TRU-UV typically eliminates them.
