Choosing Tunnel Equipment in 2026: An Operator's Honest Take on OPW/Belanger, Trident, and ICS

What follows is a working operator's take on the express tunnel equipment market as it actually exists in 2026, who owns whom, what's changed since the 2021-22 capital cycle, and how to make a decision that you won't regret five years in.

The market structure most operators get wrong

Before you can pick equipment, you have to understand who actually makes it in 2026. The independent-brand era is mostly over. Three corporate parents now control the majority of the tunnel equipment, POS, and chemistry sold into new builds:

• Dover Corporation (NYSE: DOV) → OPW Vehicle Wash Solutions, which contains PDQ, Belanger, ICS (acquired January 2021), Kesseltronics, and Transchem (acquired January 2024, brings Turtle Wax Pro chemistry and ClearWash reclaim). Marketed under the "United We Wash" cross-brand motto since Car Wash Show 2025.
• Vontier Corporation (NYSE: VNT) → DRB (acquired September 2021 for $965M from New Mountain Capital). Owns the Patheon, SiteWatch, and Washify POS platforms. Largest installed base in conveyor tunnel POS.
• Genstar Capital → Sonny's Enterprises (acquired August 2020). Vertically integrated equipment plus the largest factory-owned service network in the Southeast through Car Wash Services of the Southeast (Georgia, Carolinas, Tennessee, Kentucky) and direct Florida service.

Berkshire Partners owns National Carwash Solutions (NCS), which holds Ryko (touch-free in-bay), MacNeil (tunnel), and the unified NCS Chemistry line (formerly Lustra, Cleantouch, and ProFormance, sunset and rebranded May 7, 2024).

Major independents at scale in 2026 include Coleman Hanna, Washworld (touch-free in-bay only), and WashTec (Germany-based with a smaller US tunnel presence). Tommy Car Wash Systems is both a tunnel operator and an equipment manufacturer to its own franchisees, a vertical model that gives it scale without the traditional distributor footprint.

What matters when you're choosing equipment

The questions that should drive your decision, in order:

1. Service network in your specific market: How far are factory-trained techs from your site? Lead time on a service call?
2. Parts availability: Can I get a critical part in 48 hours, or am I waiting two weeks?
3. Uptime track record: How many hours per year is this system down for unplanned maintenance?
4. Total cost of ownership over 10 years, not sticker price at purchase
5. Throughput: Realistic cars per hour at peak, not the brochure number
6. Wash quality consistency: Same finish on Car 1 and Car 400

Sticker price is rarely the right tiebreaker. A $40K savings on tunnel equipment that costs you 8 hours of downtime per month at $400/hour in lost revenue is a $38K loss in Year 1 alone.

Tunnel systems: OPW Vehicle Wash Solutions (PDQ and Belanger)

Why I run it

PDQ and Belanger are the equipment I've personally rebuilt, troubleshot at 6am, and trained crews on across multiple portfolios. Since the Dover consolidation under OPW VWS in 2019, the two product lines have been maintained as distinct brands with shared engineering, service tooling, and parts logistics. The reasons it wins for me:

• Parts logistics: OPW VWS maintains regional inventory through their distributor network and the Transchem acquisition tightened their chemistry-side support. Realistic lead time on a critical wear part in the Southeast is 24-72 hours.
• Modular component design: Failed soft cloth wraps, dryer components, and contour arms can be swapped without dropping the entire system.
• Brand continuity: Despite the corporate consolidation, the Belanger Vector and PDQ LaserWash product lines have continuous engineering lineage going back decades.
• Tunnel throughput: Conservative spec'd CPH is realistic, not aspirational.

Honest tradeoffs

• Up-front cost is mid-pack, not the cheapest option.
• OPW VWS uses a distributor-network model rather than the factory-owned regional service arm Sonny's operates through CWSSE. If your distributor relationship is weak, the brand support story doesn't help you.
• The cross-brand integration story ("United We Wash") is newer than the individual product lines, so operators standardizing across PDQ tunnel + ICS POS + Transchem chemistry are buying into a unified ecosystem that's still maturing.

What I'd consider against it

• Sonny's: Strong product with a meaningful factory-owned service footprint in the Southeast. If a Sonny's service tech is closer to your site than the nearest OPW VWS distributor, that's a legitimate reason to spec Sonny's.
• Coleman Hanna Carwash Systems: Independent with a long-standing distributor network. Credible tunnel option, particularly in markets where their distributor has strong service depth.
• Tommy Car Wash Systems: Their compact equipment package targets operators who want manufacturer-direct support; vertical integration with the Tommy's Express operating business is part of the story.
• MacNeil (NCS family): Solid tunnel platform with broad North American service through the NCS service network.

Service network beats brand preference every time. If a competitor has techs within 30 minutes of your site and the OEM I'd otherwise recommend is 90 minutes out, I'll tell you to spec the competitor.

Point of sale and pay stations: ICS

Why I run it

ICS (Innovative Control Systems, based in Bethlehem, PA) was acquired by Dover/OPW in January 2021 and now sits under OPW VWS alongside PDQ and Belanger. The combined Dover ecosystem story is real, but ICS earned its position on its own merits:

• WashConnect platform: Multi-site POS and management software with cohort-level membership analytics. Handles complex membership programs, multi-tier, family plans, fleet accounts, without breaking.
• Auto Sentry Flex / Flex HD: 17-inch touch flagship pay terminal with EMV/tap. Lower failure rate per transaction than most competitors I've operated.
• API integrations: Clean integrations with QuickBooks, marketing platforms like Rinsed, and the Auto Passport RFID/LPR module set.
• Tighter integration story with PDQ and Belanger tunnel equipment under the unified OPW VWS umbrella.

Honest tradeoffs

• Distant #2 to DRB in installed base on conveyor tunnel POS. DRB markets itself as serving 8 of the top 10 conveyor chains in the US.
• Cost is mid-to-upper range, not the cheapest POS option.
• Cross-platform CRMs like Rinsed are increasingly the membership marketing and analytics layer, so the depth of any one POS platform matters less than it did in 2022.

What I'd consider against it

• DRB Patheon (Vontier): The current go-forward DRB platform. Browser-based hybrid cloud POS, subscription-licensed. Super Star Car Wash announced a 118-site, 550,000+ member migration to Patheon in May 2026, confirming Patheon as the strategic platform.
• DRB SiteWatch (Vontier): Legacy Windows-based POS, still supported and sold. Mature membership feature set, native QuickBooks Interface, supports up to 64 pay stations per site. Strong choice for operators not ready to migrate to Patheon.
• Sonny's pay station and tunnel controller, with the January 2025 Fiserv payment processing partnership, is a credible integrated option for operators on Sonny's equipment.
• Washify (DRB) for single-site operators who want cloud-only and entry-level pricing.
• WashCard Systems (now owned by D&S Car Wash Supply, acquired April 2024): Strong in self-serve and IBA payment, less common on express conveyor.

If you're building a portfolio with PDQ or Belanger tunnel equipment, ICS gives you the tightest Dover-ecosystem integration. If you're building on Sonny's equipment, run Sonny's controller and pay stations. If you're acquiring a multi-site portfolio already on DRB, migrate the new sites to Patheon and let the existing SiteWatch sites run until natural refresh.

Chemistry: Trident Wash Systems

Why I run it

Trident Wash Systems is based in Pineville, NC, 20 minutes from our Charlotte office. They're a vertically integrated equipment-plus-chemistry manufacturer, smaller than the national chemistry players (Simoniz, NCS Chemistry, DuBois/BlendCo) but with three things I value at our scale:

• Regional support: Field chemists who actually visit Southeast sites, calibrate equipment, and dial in formulations to local water hardness.
• Equipment-chemistry integration: Their chemistry is engineered for their own metering and dilution platforms, which removes one layer of "who's responsible when something goes wrong."
• Cost discipline: Competitive cost per car without going to the cheapest tier where you start losing wash quality consistency. Realistic blended chemistry cost for a full express menu lands at $0.55-$0.85 per car (lower bound on a value menu mix, upper bound on a premium menu with ceramic top wash).

Honest tradeoffs

• Brand recognition is lower than NCS Chemistry, Simoniz, or DuBois/BlendCo. Some operators have to be educated on it.
• Smaller distribution network than the largest national chemistry players. If you're operating outside the Southeast, the regional support advantage shrinks.
• Premium positioning (graphene, ceramic-infused top wash) is now table-stakes across the industry, so the chemistry brand alone is rarely a deciding factor at the consumer level.

What I'd consider against it

• NCS Chemistry (Berkshire Partners): The largest equipment-tied chemistry brand after the May 2024 unification of Lustra, Cleantouch, and ProFormance under the NCS Chemistry name. Strong distribution, broad menu coverage.
• Simoniz USA: 100+ year brand heritage with a full-service direct model, monthly site visits, business and marketing plans bundled with the chemistry contract. Carbonite graphene-infused and Ceramic Sealant are strong premium SKUs.
• DuBois/BlendCo: BlendCo has been part of DuBois Chemicals since 2009. Mid-market national chemistry, signature "Lots Of Suds" line.
• Stinger Chemical: Independent Houston-based, full tunnel-plus-detail chemistry line. Strong in Texas and the Gulf.
• Qual Chem: Independent, high-concentrate professional positioning. Used by many of the largest tunnel operators.
• Diamond Shine: Still active in 2026, regional strength in the Southeast.
• Transchem (Dover/OPW VWS, includes Turtle Wax Pro): The captive chemistry now bundled with PDQ/Belanger/ICS under the OPW VWS umbrella, since Dover's January 2024 acquisition.

Chemistry as a percent of revenue benchmarks at 5-10% for a well-run express tunnel; best operators land at 5-7%, and the way to get there is metering and menu engineering, not buying the cheapest chemistry.

The decision framework

When I spec a new site, the priority order is:

1. Service network in your market: Confirm tech response time on a Tuesday morning service call. If the nearest factory-trained tech is over 90 minutes away regardless of brand, that's a build-risk you have to price into your underwriting.
2. Existing portfolio compatibility: If you already operate 3 sites on one brand, the operational efficiency of standardization usually beats the spec advantage of switching.
3. Capital constraints: Cheaper equipment makes sense only if you've modeled the lifetime cost of downtime, not just the sticker price.
4. Throughput requirements: A high-volume site (350+ CPD stabilized) needs equipment that's been proven at that throughput. A 200 CPD site has more flexibility.
5. Ecosystem strategy: Are you building toward a unified Dover stack (PDQ or Belanger tunnel + ICS POS + Transchem chemistry)? A DRB-anchored stack with Patheon POS and the OEM tunnel of your choice? Or a Sonny's-integrated single-vendor build? Each is defensible; mixing without intent creates support headaches.

What's changed since 2022

The industry has consolidated meaningfully in the last 36 months and operators should know the landscape:

• Dover continued building out the OPW VWS portfolio with Transchem (January 2024), unifying tunnel + POS + chemistry + reclaim under one corporate umbrella.
• DRB consolidated around Patheon as the go-forward platform, with major migrations announced (Super Star Car Wash, 118 sites, May 2026) and the Washify+Patheon hardware partnership covering ~2,500 sites globally.
• Berkshire Partners recapitalized NCS, which unified its chemistry brands as NCS Chemistry in May 2024 and continues to build out the integrated equipment-plus-service-plus-chemistry play.
• Sonny's added vertical depth through Genstar Capital's ownership, acquiring distributors (WashTech and Wash Pros in Canada, Sunbelt Car Wash Services in the Gulf) and the WashMetrix software business in 2025.
• ZIPS Car Wash filed Chapter 11 in February 2025 with $654M of debt and 260 locations, the clearest signal yet that the 2021-22 build cycle outran demand in many markets.
• Whistle Express acquired Take 5 Car Wash from Driven Brands in April 2025 for $385M (385 units, roughly 8x on $50M+ EBITDA), making Whistle the largest US express operator at 530+ locations across 23 states.
• Mister Car Wash announced its take-private by Leonard Green & Partners in February 2026 at $3.1B enterprise value.

The implication for equipment selection: corporate ownership of the brands you're buying matters more than it did in 2020. A long-term decision should account for who owns the manufacturer, how committed they are to the segment, and how the service network actually performs in your specific market.

What we do at WLG

We spec equipment packages for every development project we touch, and we spec what we'd run ourselves. Our distributor relationships exist because we wanted leverage on pricing and lead times for our own development pipeline, not because we wanted to become a salesforce. When the right answer for a specific site is a brand we don't distribute, we say so.
