• Walk-in Environmental Test Chambers: The Hidden Tech Gem in Industrial Testing

  Nov 18, 2025

  In industrial manufacturing's "quality defense line", walk-in environmental test chambers are low-key yet critical. As "environmental simulation masters", they replicate extreme conditions from polar cold to tropical heat, testing large equipment and batch products. Their hidden technical strengths merit in-depth exploration. I. Spacious Interior for Flexible Adaptation to Diverse Testing Needs The "walk-in" design is a core breakthrough. With  several to dozens of cubic meters of space, it accommodates large products (automotive parts, electronic devices) and enables batch testing of small/medium items. New energy vehicle battery packs and rail transit systems can be tested integrally without disassembly. Flexible racks and zoning fit various sample shapes, solving traditional equipment's "unfit and unstable" issues. II. Precise Temperature Control for Highly Simulating Diverse Extreme Environments Precise temperature control is its core advantage, with a temperature range of -70℃ to 250℃ and humidity of 20%RH to 98%RH, replicating high-altitude, desert and coastal environments. Using PID algorithms and multi-point sensing, temperature/humidity fluctuations are controlled within ±0.5℃ and ±2%RH, ensuring reliable data. It simulates high-altitude conditions for aerospace and verifies consumer electronics' performance in extremes to support product iteration. III.

• Have You Completed These Critical Checks Before Delivering a High-Low Temperature Humidity Test Chamber?

  Nov 15, 2025

  1. Preparation for Load-bearing and Dimensional Adaptation • The load-bearing capacity of the site floor shall strictly meet the core requirement of ≥500kg/m², which is a key prerequisite for ensuring the long-term stable operation of the equipment and avoiding equipment deformation or safety hazards caused by insufficient load-bearing capacity. • It is necessary to accurately confirm the external dimensions of the test chamber specified in the technical specification in advance. Combined with the on-site actual survey of the transportation and installation path, ensure that the equipment can smoothly pass through all key passage nodes such as elevators, laboratory doors and corridors, so as to avoid delay in delivery and installation due to inconsistent dimensions. 2. Preparation for Installation Site Conditions • The floor of the installation site shall be flat without protrusions and depressions, and the ventilation conditions shall meet the basic standards for equipment operation. At the same time, there shall be no flammable, explosive, corrosive gases or dust in the environment, as such substances will seriously affect the service life of equipment components and the accuracy of test data. • Strong electromagnetic radiation sources such as high-voltage lines and large motors should be actively avoided near the equipment installation location, as strong electromagnetic interference may cause disorder of the equipment control system, thereby affecting the temperature and humidity control accuracy of the test chamber. • A floor drain that meets the drainage standards must be provided within 2 meters of the equipment's refrigeration unit. This requirement is to timely discharge the condensed water generated during the operation of the refrigeration system, so as to avoid water accumulation soaking the equipment or polluting the site environment. • Sufficient maintenance and operation space shall be reserved around the equipment in accordance with specifications. The specific requirements strictly follow the following standards: Area A ≥80cm, Area B ≥60cm, Area C ≥110cm, Area D ≥110cm. Sufficient space is a necessary guarantee for later equipment maintenance, calibration and component replacement.
