Product Overview

ALP Technology's Walk-in Temperature Test Chamber (Model: ALP-GDWSW-26C) is a large-scale, high-performance testing solution designed for evaluating the reliability and performance of oversized products, large batches, or complete assemblies under controlled temperature and humidity conditions. Its spacious interior allows personnel to enter for direct operation and monitoring, making it ideal for testing automotive parts, aerospace components, large electronic systems, and new energy batteries. This walk-in temperature test chamber accurately simulates extreme environments from -40℃ to +100℃ with humidity control from 10% to 95% RH, helping manufacturers identify design flaws, verify long-term durability, and ensure product reliability before market launch.

Product Features

ALP's Walk-in Temperature Test Chamber is engineered with robust features for precision, flexibility, and ease of use:

Customizable Modular Construction: Panels are easy to assemble with tongue and groove design held together by cam-latches and silicone sealant. Embedded metal banding links cam-latches for a secure, strong unit.
Wide Performance Range: Temperature range from -40℃ to +100℃ and humidity range from 10% to 95% RH, with a heating rate of ≥3℃/min and cooling rate of ≥1℃/min (no load), delivering fast, reliable thermal cycling.
High Precision Control System: Features a 7-inch programmable color touch screen controller (WENVIEW brand) supporting 120 patterns and up to 1200 segments. It offers multi-language support (Korean, English, Chinese, Russian, Vietnamese) and advanced PID algorithm with auto-tuning function.
Durable Construction: Interior workroom is crafted from SUS304 stainless steel for excellent corrosion resistance; exterior from powder-coated cold-rolled steel. Insulated with rigid polyurethane foam and rock wool for minimal temperature loss.
Robust Refrigeration & Heating: Equipped with BOCK semi-enclosed compressors (20HP×2) using chloride-free refrigerants R404A & R23. The heating system uses nichrome alloy electric wire heater with PID.SSR synchronous coordinated control.
User-Friendly Accessories: Double doors (W1200×H2000mm×2) with anti-fog observation window, customizable cable ports, trouble lights, and heavy-duty floor loading up to 1500 PSF distributed.
Comprehensive Safety Protections: Includes compressor overpressure/overheating/overcurrent protection, over-temperature protection, earth leakage protection, phase sequence protection, and emergency stop switch with sound-light alarm.
