These large environmental chambers are tailored for oversized components, full-vehicle modules, aerospace structures, EV battery assemblies, and industrial equipment requiring large-volume, high-stability environmental control.

With temperature ranges from –70°C to +150°C, humidity control from 20–98% RH, and configurable test room capacities from 5 m³ to 60 m³ (customizable beyond 100 m³), LIB industry's custom large environmental chambers deliver stable, repeatable, and precise testing conditions for qualification, validation, reliability, and stress screening programs.the integrated walk-in series offers greater test loading capacity, multi-point airflow uniformity, and modular mechanical architecture, ensuring consistent performance even under full-scale operational loads.

Key Advantages of Integrated Testing Custom Large Environmental Chamber

High-Capacity Airflow for Large-Volume Uniformity

A multi-duct circulation system maintains ±0.5°C temperature uniformity across test rooms up to 60 m³.Air velocity of 1.5–3.0 m/s ensures identical stress exposure to components of varying size and placement, supporting high-reliability and repeatable evaluation of large assemblies

High-Power Thermal & Humidity Control System

Equipped with evaporators, modular heater, and dual-loop refrigeration, the custom large environmental chamber delivers:

Heating rate: 3°C/min

Cooling rate: 1°C/min

Humidity stability: ±2.0% RH
This performance enables demanding climatic cycling, material behavior simulation, and environmental endurance programs.

Reinforced Structural Insulation

A 100 mm multi-layer insulation barrier with thermal-deviation compensation modules ensures stable control even during long-duration cycling.

Designed for High-Duty Testing Cycles

The integrated testing custom large environmental chamber is engineered for continuous operation, supporting:2,000+ test cycles,24/7 stable running.Ideal for reliability qualification, accelerated life testing (ALT), and HALT/HASS-level environmental simulation.

Flexible Walk-In Design for Oversized & Heavy Samples

The walk-in configuration allows operators to enter the test area directly, making handling and installation of oversized, high-weight, or fully assembled products safe and efficient. Reinforced flooring and structural support ensure load stability without compromising environmental uniformity.

Key Recommendations for Reliable Large-Volume Reliability Testing

1. How does the integrated testing custom large environmental chamber maintain temperature stability in large volumes?

A multi-zone PID control system coordinates heating, cooling, and humidity subsystems. Real-time compensation algorithms ensure stable performance with ±0.5°C stability and ±1.0°C uniformity, even under high internal thermal loads.

2. Is it possible to perform multi-condition combined testing in the same room?

Yes. Custom configurations allow combining temperature, humidity, airflow, lighting, or dust filtration modules within a single walk-in chamber to simulate real-world operational environments more accurately.

3. Are ultra-fast thermal cycle upgrades available?

Yes. Optional modules provide up to 5–15°C/min transitions for high-stress, high-speed reliability verification programs.
