Walk-in Temperature Humidity Test Chamber

The walk-in design is built for projects where standard cabinet chambers cannot provide enough internal space. It supports larger samples, multiple racks, and flexible fixture layouts.

Key features:

• •Large internal space for full-size products and assemblies.
• •Suitable for batch testing and multi-sample validation.
• •Custom chamber dimensions according to sample size.
• •Flexible door structure and sample access design.
• •Floor load design based on test object weight.
• •Practical for R&D labs, production QC, and third-party test centers.

This structure is especially useful for large products, assembled systems, packaging tests, and batch reliability validation.

As a walk-in temperature humidity test chamber, this equipment simulates controlled heat, cold, humidity, damp heat, and cyclic climatic conditions for reliability testing.

Typical test modes:

• •High temperature testing.
• •Low temperature testing.
• •Constant temperature and humidity testing.
• •Damp heat testing.
• •Alternating temperature humidity testing.
• •Temperature cycling for large samples.
• •Storage and aging tests under controlled conditions.

Temperature range, humidity range, chamber volume, cooling capacity, and airflow design should be selected according to the sample size, heat load, and test program.

The chamber is suitable for products that are too large for standard cabinet chambers or require batch-level environmental simulation. It helps engineers evaluate durability, sealing performance, corrosion risk, deformation, electrical stability, and material aging under temperature and humidity stress.

Typical applications:

• •Automotive components and interior/exterior parts.
• •Home appliances and industrial equipment.
• •Communication cabinets and electronic assemblies.
• •Packaging materials and transport simulation samples.
• •Aerospace and aviation components.
• •Large plastic, rubber, metal, and coating samples.
• •Batch testing for production quality control.
• •Third-party laboratory reliability testing.

The main value is not just chamber size, but the ability to reproduce stable climatic conditions for large or multiple samples.

Large chambers require careful airflow and refrigeration design to maintain stable temperature and humidity uniformity. SANWOOD can design the system according to chamber volume, sample layout, heat load, and test requirements.

System highlights:

• •Programmable touchscreen controller.
• •Multi-step temperature and humidity profiles.
• •Optimized airflow design for large chamber uniformity.
• •Built-in refrigeration and humidification system.
• •Optional RS232, RS485, or Ethernet communication.
• •Optional PC monitoring and data recording.
• •Modular refrigeration design for easier maintenance.
• •Alarm protection for abnormal operation.

Final configuration should be selected according to chamber size, temperature range, humidity range, cooling rate, sample heat load, and installation environment.

Walk-in temperature humidity chambers are usually project-based systems. SANWOOD can customize chamber size, door type, floor structure, airflow layout, refrigeration capacity, humidity system, cable ports, observation windows, lighting, control system, and power supply according to the customer’s test plan and installation site.

The chamber can be configured to support test conditions related to common environmental testing methods, including IEC 60068-2-1, IEC 60068-2-2, IEC 60068-2-30, IEC 60068-2-78, ISO 16750, and MIL-STD-810.

Customization options:

• •Inner chamber size and walk-in layout.
• •Temperature and humidity range.
• •Cooling capacity and heating capacity.
• •Air duct and airflow direction.
• •Floor load and sample access design.
• •Door structure, lighting, and viewing window.
• •Cable ports and communication interface.
• •Local voltage and installation requirements.

SANWOOD Technology can provide model selection, engineering layout support, installation guidance, commissioning, maintenance, repair, and technical service according to project requirements.
