High Low Temperature Alternating Constant Temperature Test Chamber

Product Overview

This high low temperature alternating constant temperature test chamber is a controlled environmental testing system designed to expose products, components, and materials to repeatable high-temperature, low-temperature, and alternating-temperature conditions. Its 408 L effective volume provides a practical workspace for reliability evaluation while maintaining tightly defined temperature performance. The equipment supports controlled operation from 20°C to +100°C, helping laboratories establish dependable evidence of thermal endurance and product consistency.

The system is suited to battery testing, automotive component validation, electrical and electronic product assessment, and environmental simulation for parts and materials. It enables teams to assess how samples respond to sustained thermal exposure and repeated temperature transitions before products move into production, qualification, or further engineering review. The chamber is particularly useful where temperature reliability must be evaluated across different assemblies, housings, connectors, electronic modules, and material constructions.

Built for demanding laboratory operation, this unit combines controlled heating and cooling performance with specified limits for fluctuation, deviation, gradient, and overshoot. These performance controls help users run consistent test conditions, compare results between samples, and support structured reliability programs. With three-phase power and a robust 540 kg equipment mass, the system is configured as a substantial environmental test asset for professional research, development, and quality environments.

Key Features

• Controlled 20°C to +100°C Test Range: The equipment provides full-range controllable temperature operation from 20°C to +100°C. This range supports high-temperature, low-temperature, and alternating-temperature environmental simulation within one integrated test space.

• 408 L Effective Test Volume: A 408 L chamber provides useful capacity for batteries, automotive parts, electrical products, electronic assemblies, and material samples. The internal dimensions of W600 mm × H850 mm × D800 mm give engineering teams room to arrange test articles while retaining a defined environmental envelope.

• Stable Temperature Performance: Temperature fluctuation is specified at ≤±0.5°C after stabilization. This controlled stability is important when comparing sample behavior over time, identifying temperature-sensitive failures, and reducing uncertainty caused by chamber-condition variation.

• Defined Temperature Accuracy Limits: The unit specifies temperature deviation of ≤±2.0°C and temperature gradient of ≤±2°C after stabilization. These limits support more reliable environmental exposure by controlling the difference between nominal conditions and the temperatures experienced within the test space.

• Alternating Thermal Cycling Capability: The system supports non-linear, no-load average heating rates of 1 to 3°C/min across the range and cooling rates of 0.75 to 1°C/min. This allows laboratories to introduce controlled temperature changes for thermal cycling and environmental reliability evaluation.

• Limited Transition Overshoot: Heating and cooling overshoot is specified at ≤±2.0°C. Limiting overshoot helps protect test integrity during setpoint transitions and is valuable when samples require disciplined exposure to programmed thermal conditions.

• Professional Electrical Configuration: The equipment operates on AC 380 V, 50 Hz, three-phase power with a 5.0 kW rating. This configuration suits fixed laboratory installations that require dependable electrical supply for controlled environmental testing.

• Controlled Laboratory Noise Level: Noise is specified at ≤70 dB in A-weighted sound level. This supports placement in professional testing areas where equipment performance must be balanced with the operating environment.
