TQC Sheen C&W Humidity Cabinet

TQC Sheen C&W Humidity Cabinets are designed to reproduce test conditions of high humidity at constant or cycling temperatures. The test chamber environment is created by water being heated to precise temperatures to generate water vapour. The water vapour saturates the air in the test area which is constantly being circulated by the internal fan to ensure even distribution. The test panels or components are exposed to the moisture enriched air, allowing the water to be absorbed by the coating. Oxidising with the base metal results in either blistering of the coating or the formation of red rust or oxidisation on a non–ferrous metal. This test is used to reproduce the exposure to naturally occurring condensation or by cycling the temperature, in the cabinet dew formation can be produced.

Used by coatings laboratories, automotive manufacturers, packaging producers, and materials testing facilities, humidity cabinets like this help assess how coatings and materials will perform in moisture-rich environments before they reach real-world conditions.

Pioneering designs have made TQC Sheen C&W the UK leader in the manufacture of accelerated corrosion and environmental test cabinets.

Why it matters

The Humidity Cabinet helps identify coating failures early, reducing the risk of corrosion, blistering and product degradation in real-world environments.

By simulating high humidity and condensation conditions, it supports more reliable product development and quality validation.

Accelerated environmental testing helps reduce time-to-market by replicating long-term exposure in a controlled laboratory setting.

Operating Modes

TQC Sheen C&W Humidity Cabinets provide a wide range of environmental test conditions:

• Any constant temperature between 30°C and 70°C. +/- 1°C accuracy
• Cyclic temperatures, step –up / step-down over time.
• Constant high humidity – 95% to 100% saturated.

These controlled conditions allow testing teams to replicate specific climates and environmental scenarios, supporting consistent and repeatable testing across different applications.

Precise Control

TQC Sheen C&W Humidity Cabinets are designed for ease of operation. Their comprehensive package of control and display features ensures that all cycles, events and functions can be closely monitored:

• Microprocessor controller with seven-programme memory.
• Full digital display of test conditions. Low water sensor protection.
• Air circulation by internal fan ensures uniform test conditions.
• Time cycle facility for precise test duration control.
• NTC temperature sensor for precise control.
• Over temperature safety cut out system.

This level of control helps ensure reliable, repeatable test results, supporting accurate quality control and product development decisions.

Design Benefits

All TQC Sheen C&W cabinets with their clean functional design are manufactured from high quality materials selected specifically for this application. They are made out of specially formulated fire retardant glass reinforced polyester (GRP) with high chemical, water and temperature tolerance. The Wet seal apex roof is insulated or transparent. The construction of the Humidity Cabinets is corrosion resistant throughout. The control panel has an ergonomic design. Standard panel racks are included, options are available. Transportation of the Humidity Cabinets in areas of restricted access is made easier due to the compact design aided by wheels and removable lids.

This robust construction supports long-term use in demanding laboratory environments while maintaining stable testing conditions.

Humidity Function

TQC Sheen C&W cabinets come in a wide range of types, Humidity Cabinets are dedicated cabinets only allowing humidity testing. You can also obtain a standard corrosion test with humidity function added. Cabinets with salt spray / humidity combined, and salt spray / prohesion / humidity combined are available.

This flexibility allows laboratories to adapt testing setups to different materials, coatings and environmental requirements.

Scope of supply

Each Humidity Cabinet comes with:
1x CW4088 Installation kit
1x CW4035 Set of Collection Vessel (2 funnel, 2 cylinder)
1x CW5882 Adapter for pipe
1x VF7101 Corrosion Handbook
