Product Overview

ALP Technology's 2-Zone Thermal Shock Test Chamber is a specialized reliability testing system designed to evaluate the resistance of materials and products to extreme, rapid temperature changes. This 2-zone thermal shock test chamber employs a basket-type design with two independently controlled zones-a high-temperature zone and a low-temperature zone . During testing, a motor-driven basket rapidly transfers the test specimen between these zones, simulating the drastic temperature fluctuations products may encounter during real-world use. This 2-zone thermal shock test chamber is widely used across electronics, automotive, aerospace, and semiconductor industries to identify design flaws, assess material durability, and perform environmental stress screening.

Product Features

ALP's 2-Zone Thermal Shock Test Chamber is engineered for precision, speed, and efficiency:

Rapid Temperature Transfer: The high-speed basket lift system transfers specimens between hot and cold zones in less than 10 seconds (≤3-5 seconds for high-performance models), ensuring immediate thermal shock as required by international standards.
Wide Temperature Range: High-temperature zone reaches up to +220°C, while the low-temperature zone cools down to -75°C, accommodating a broad spectrum of testing requirements.
Fast Temperature Recovery: Temperature recovery time is ≤5 minutes, enabling efficient testing cycles and maximizing throughput.
Precision Control System: Features a programmable color LCD touch screen controller with Ethernet connection for PC link and remote monitoring . Supports multi-language interface and complex test profile programming.
Durable Construction: Interior workroom is crafted from SUS304 stainless steel for corrosion resistance and easy cleaning; exterior from powder-coated steel for durability .
Advanced Defrosting System: Capable of continuous impact testing of 1000 cycles without defrosting, significantly improving test efficiency.
Live Testing Support: Integrated cable hole enables power-on testing of electronic devices and batteries with continuous data monitoring.
Comprehensive Safety Protections: Includes over-temperature protection, compressor overpressure/overheating protection, earth leakage protection, and over-current protection.

FAQ

Q1: What is the difference between a 2-zone and 3-zone thermal shock test chamber?

A: A 2-zone thermal shock test chamber consists of a high-temperature zone and a low-temperature zone, with the specimen transferred between them via a motorized basket (dynamic testing). A 3-zone chamber has a separate testing zone where the specimen remains stationary, and hot/cold air is introduced via dampers (static testing). The 2-zone design offers faster transfer times and is more compact.

Q2: What types of products are typically tested in this chamber?

A: This chamber is used for testing electronic components, semiconductors, IC chips, automotive parts, aerospace materials, metals, plastics, rubber, and medical devices.

Q3: How does the defrosting system work?

A: The chamber features an advanced defrosting system that enables continuous impact testing of up to 1000 cycles without needing to defrost, significantly improving test efficiency and reducing downtime.

Q4: Can I monitor tests remotely?

A: Yes. The chamber is equipped with Ethernet and USB interfaces for PC connection, remote monitoring, and data export. Optional smartphone/tablet access is also available.

Q5: Can ALP customize the chamber size or features?

A: Yes. ALP's greatest advantage is the ability to customize a variety of non-standard test chambers according to specific customer requirements, including dimensions, temperature range, load capacity, and optional accessories.
