TQC Sheen C&W Cyclic Corrosion Cabinet

Manufactured by C&W within our TQC Sheen brand, the C&W Cyclic Corrosion Cabinet is a programmable environmental test chamber built to deliver accelerated corrosion testing that reflects how coatings and substrates behave in service – not just under continuous salt fog.

Used by automotive OEMs and their coatings suppliers, aerospace and defense manufacturers, offshore and marine engineering firms, electronics manufacturers, metal packaging producers, and paints and coatings laboratories, the cabinet supports quality, R&D and production teams whose corrosion decisions must hold up against automotive OEM specifications and international standards.

The cabinet is manufactured from specially formulated fire-retardant glass-reinforced polyester (GRP) with high chemical and temperature tolerance, and is corrosion-resistant throughout. Apex lids are available in a range of composite materials and are supported by gas springs; a wet or dry seal option and removable lids and base frames make delivery and installation in restricted-access areas straightforward.

Why it matters

Corrosion data that stands up to automotive OEM and international audit. The cabinet supports testing to ASTM B117, ISO 9227 and 12+ automotive OEM protocols including Ford EU B 153-2, Nissan NES M0007, Renault D41 010, Toyota TSH 1555G, VDA 624-415 and VW PV 1210 – so pass/fail decisions are defensible with customers, certifying bodies and internal quality management systems.

Model real-world corrosion, not just steady-state salt fog. Programmable cycles combine salt spray, dwell and ramp, high humidity, air purge, forced air drying and dry heat – so R&D and materials engineers replicate the wet-dry-thermal transitions that actually cause corrosion in service, rather than accelerated failure modes that never occur outside the lab.

Robust, low-maintenance uptime. GRP construction is corrosion-resistant throughout, the peristaltic pump and atomizer are engineered against blockage, and consumables (filters, tubing, spray gaskets) are stocked as spare parts – so the cabinet runs when the production or R&D program needs it, and downtime for maintenance is predictable.

Operating modes and test conditions

The cabinet provides a full range of environmental test conditions, selectable individually or in any programmed sequence:

• Conventional salt spray / salt fog
• Dwell and ramp functions
• High humidity, 98% RH, at constant or cyclic temperature
• Air purge cycles
• Forced air drying
• Dry heat, ambient to 70°C
• Ambient temperature control to 55°C +/- 1°C

The user-friendly programmable logic controller lets you combine any of these conditions in any sequence, for any pre-set duration. The cabinet can also be operated in single mode as a Cyclic Prohesion Cabinet, CASS Cabinet, Conventional Salt Spray / Salt Fog Cabinet or Humidity Cabinet – so one instrument replaces what could otherwise be several dedicated cabinets. 

Precise control and operation

Every unit incorporates a microprocessor controller capable of holding up to seven programs with unlimited event entries, plus an end-of-test cycle counter. The sophisticated atomizer delivers even salt spray distribution and precise collection rates throughout the chamber. Salt solution flow is controlled by a variable-speed heavy-duty peristaltic pump and flow meter – ensuring accurate collection rates and preventing atomizer blockage.

Protection against overheating and low water is built in as standard. A dry / moist air facility supports rapid transitions between test regimes with minimum fluctuation, and the filling and sterilization entry is easily accessible to prevent algae buildup. A fully adjustable water temperature control with digital display is included, with an optional low-level alarm system available.

Available Cyclic Corrosion Cabinet models

Three series are available, each in five chamber volumes:

• SF/CCT – standard cyclic corrosion test cabinet
• SF/CCT-E – cyclic corrosion test cabinet with Eurotherm control
• SF/CCT/VH – cyclic corrosion test cabinet with Variable Humidity

Chamber volumes: 200 L, 450 L, 750 L, 1000 L and 2000 L – sized for sample throughput from single test panels through to full component assemblies. Your TQC Sheen C&W specialist can advise on the right series and volume for your standards, sample sizes and site constraints during enquiry.

What’s included

Each Cyclic Corrosion Cabinet is supplied with:

• 1x CW4088 Installation kit
• 1x CW4035 Set of Collection Vessels (2 funnels, 2 cylinders)
• 1x 5 kg Salt plus Certificate
• 1x CW5882 Adapter for pipe
• 1x VF7101 Corrosion Handbook

Optional accessories are available – contact us to discuss your test protocols and consumable requirements.

Testing to international and OEM standards

The Cyclic Corrosion Cabinet supports accelerated corrosion testing to a wide range of international and automotive OEM standards, including:

ASTM B117 – Standard Practice for Operating Salt Spray (Fog) Apparatus

ISO 9227 – Corrosion tests in artificial atmospheres, salt spray tests

CCT I, II, IV – Cyclic corrosion test protocols

Ford EU B 153-2, Nissan NES M0007, Renault D41 010, SWAAT and MASTMAASIS Honda 5100Z, Toyota TSH 1555G, VDA 624-415, VW PV 1210 – automotive OEM cyclic corrosion protocols

JIS K 5622-7, Unichem 692 and 741 – additional regional and industry protocols

Spares and consumables

Genuine TQC Sheen C&W spare parts and consumables keep your cabinet running to specification:

• Peristaltic Pump (CW4024) – 4-roller dosing pump with mount plate and tube for accurate salt solution delivery
• Annual Consumables Pack (CW4052) – includes 5 salt solution filters and 3 meters of peristaltic pump tubing, sized for one year of typical use
• Salt Solution Filters (CW4043) – pack of 5, keeps salt solution feed clean and prevents atomizer blockage
• Spray Gasket/Washer – ensures proper sealing and spray function during accelerated testing

What happens after you enquire

When you enquire about the Cyclic Corrosion Cabinet, our TQC Sheen C&W specialists will confirm which standards you need to test to, review your typical sample sizes and throughput, and recommend the right series (SF/CCT, SF/CCT-E or SF/CCT/VH) and chamber volume (200 L to 2000 L). They will also confirm site requirements – the cabinet’s compact design and removable lids and base frames simplify delivery to areas of restricted access.

For purchasing teams, we provide clear model references across the three series and five volume options, quotation turnaround, and the technical documentation you need for internal sign-off. After delivery, our team supports installation, first-use walkthrough (programming test cycles, calibrating collection rates, setting up alarms) and initial operator training – so your team gets consistent, defensible corrosion data from day one.

Service, warranty and ongoing support

Every Cyclic Corrosion Cabinet is supplied with a 1 year parts and labour warranty as standard. Subject to agreed maintenance procedures, a 2 year warranty is available. Beyond the warranty period, the Industrial Physics global service network supports scheduled preventive maintenance, genuine spare parts and technical support – so the cabinet stays productive across its working life. Contact our support team to arrange a service, request spare parts, or discuss the extended warranty and maintenance agreement options in your region.

Operator training is available covering programme setup, cycle sequencing, salt solution and collection rate calibration, and interpretation of test results against ASTM, ISO and automotive OEM protocols – so results stay repeatable between operators, shifts and sites. Our global support network means help is available wherever you operate.
