Large Temperature Cycling Test Chamber for Environmental Reliability Testing

Product Overview

This large temperature cycling test chamber is an 800L environmental simulation system for evaluating how products, parts, and materials respond to controlled high-temperature, low-temperature, and alternating temperature conditions. Its -40°C to +150°C operating range, 0.01°C temperature indication resolution, and defined stability metrics provide a clear platform for repeatable environmental reliability assessment.

The equipment is suited to battery cells, automotive components, electrical and electronic products, and other assemblies requiring temperature-based environmental testing. The generous internal workspace supports larger test articles and organized fixture arrangements while maintaining a specified temperature gradient of no more than ±2.0°C after stabilization.

Built around clearly defined thermal performance requirements, this unit supports demanding qualification and development workflows. Average unloaded heating and cooling rates of 5°C/min across the -40°C to +85°C transition help laboratories execute accelerated thermal cycling programs with predictable timing and controlled test conditions.

Key Features

• 800L Effective Test Volume: The 1000 mm wide, 1000 mm high, and 800 mm deep internal chamber provides substantial usable capacity for battery cells, automotive parts, electrical products, and other larger specimens. Its dimensions help teams accommodate practical test setups without reducing the environmental evaluation scope.

• Broad Temperature Coverage: The system operates from -40°C to +150°C, covering low-temperature exposure, elevated-temperature exposure, and high-low temperature cycling within one controlled test environment. This range supports reliability programs that need to examine product behavior across substantial thermal variation.

• Defined Thermal Cycling Performance: Average unloaded heating from -40°C to +85°C and cooling from +85°C to -40°C are both specified at 5°C/min. These reference-backed transition rates allow engineers to plan test cycles, estimate program duration, and compare results under stated non-linear unloaded conditions.

• Fine Temperature Indication Resolution: A temperature indication resolution of 0.01°C provides detailed visibility when setting, monitoring, and documenting environmental conditions. This level of resolution is valuable where test records and repeatable chamber settings are central to engineering review.

• Controlled Temperature Stability: Temperature fluctuation is specified at ±0.5°C, while temperature deviation is no more than ±2°C after stabilization. These stated limits help define the operating environment used for evaluation and support consistent comparison between test runs.

• Specified Temperature Gradient: After temperature stabilization, the maximum difference between average temperatures at any two points inside the chamber is specified as no more than ±2.0°C. This metric uses the current temperature-gradient definition in place of the older temperature-uniformity terminology.

• Laboratory-Ready Environmental Conditions: The equipment is specified for ambient temperatures of 5 to 35°C and ambient humidity of 10% to 85%RH. Documented installation conditions give facilities teams a direct basis for evaluating laboratory compatibility before deployment.

• Industrial Three-Phase Power Configuration: AC 380V, 50HZ three-phase power supports operation of this large-capacity environmental test system. The stated electrical requirement enables straightforward coordination with laboratory infrastructure and site power planning.

Applications

Technical Specifications

The specifications above define the intended operating envelope and test-condition basis for this large environmental test chamber. Ambient conditions, specimen assumptions, stabilization-related metrics, and unloaded transition-rate conditions should be considered together when planning a test program. In particular, the listed heating and cooling rates apply under non-linear, unloaded conditions and span the stated -40°C to +85°C intervals.

For procurement review, the internal and external dimensions provide the key space-planning information. The internal dimensions establish the usable test envelope, while the external dimensions support facility-layout review. The 800KG equipment weight and AC 380V, 50HZ three-phase electrical requirement are also important inputs for installation planning.

The performance entries distinguish temperature indication resolution from chamber control characteristics. Resolution describes the 0.01°C display increment, while fluctuation, deviation, and gradient describe different stabilized-temperature criteria. Reviewing these values separately helps engineering, quality, and laboratory teams align chamber conditions with their internal environmental reliability procedures.

Why Choose This Product

• Substantial Test Capacity: The 800L effective volume and 1000 × 1000 × 800 mm internal dimensions make this system a strong fit for laboratories evaluating larger products, component assemblies, and organized multi-sample test arrangements.

• Defined Performance for Repeatable Programs: Specified temperature range, fluctuation, deviation, gradient, and transition-rate values give procurement and engineering teams concrete criteria for evaluating fitness for their environmental reliability workflow.

• Clear Facility Integration Data: External dimensions, 800KG equipment weight, ambient operating conditions, noise limit, and three-phase power requirement support earlier and more accurate installation planning.

• Versatile Environmental Test Scope: The unit is intended for battery cells, automotive components, electrical and electronic products, and materials, allowing one temperature cycling platform to support multiple laboratory qualification activities.

• Precision-Focused Test Visibility: The 0.01°C temperature indication resolution and stabilization-based performance definitions support disciplined monitoring and technically defensible environmental test documentation.
