Product Overview

ALP Technology's Walk-in Temperature Humidity Test Chamber is a large-scale, high-performance testing solution designed for evaluating the reliability and performance of oversized products, large batches of components, or complete assemblies under controlled temperature and humidity conditions. This walk-in temperature humidity test chamber provides a spacious interior that allows personnel to directly enter the working area for convenient setup, inspection, and monitoring . It is ideally suited for testing automotive parts, aerospace components, large electronic systems, new energy batteries, and other products that cannot be accommodated in standard chambers. By accurately simulating extreme temperature environments from -70°C to +150°C and humidity conditions from 10% to 98% RH , this chamber helps manufacturers identify design weaknesses, verify long-term durability under climatic stress, and ensure final product reliability before market release.

Product Features

ALP's Walk-in Temperature Humidity Test Chamber is engineered with robust construction and advanced features for precision, flexibility, and efficient operation:

Customizable Modular Construction: Panels are assembled with tongue and groove design using cam-latches and silicone sealant. Embedded metal banding links cam-latches together for a secure, strong unit. Chamber dimensions are tailored to customer specifications, accommodating virtually any test requirement .
Wide Performance Range: Standard models offer temperature range from -70°C to +150°C and humidity range from 20% to 98% RH, with optional ranges from 10% to 98% RH or even 5% to 98% RH with dehumidifier . Heating rates reach 2.0-5.0°C/min and cooling rates 0.7-3.0°C/min depending on model .
High Precision Control System: Features a programmable color touch screen controller (e.g., South Korea TEMI-1500 or equivalent) with multi-language support . It enables both fixed-value and complex multi-segment program operation, providing temperature accuracy of ±0.5°C and uniformity of ±2.0°C .
Durable Construction: Inner chamber is crafted from SUS304 stainless steel for excellent corrosion resistance; exterior from powder-coated cold-rolled steel. Insulated with rigid polyurethane foam (100-150mm thickness) plus rock wool or glass fiber for minimal temperature loss .
Energy-Efficient Refrigeration System: Utilizes powerful semi-hermetic compressors from world-renowned brands such as Germany Bock or Bitzer, with eco-friendly refrigerants R404A and R23 . Advanced refrigerant flow control technology can reduce energy consumption by up to 30% under low-temperature conditions .
Robust Safety Protections: Equipped with comprehensive safety features including compressor overpressure/overheating/overcurrent protection, over-temperature protection, earth leakage protection, phase sequence protection, and emergency stop with sound-light alarm .
User-Friendly Accessories: Includes double doors with anti-fog observation window, customizable cable ports, trouble lights, heavy-duty floor loading options, slopes for carts, and data recorders.
