Two-zone Thermal Shock Test Chamber

Advantages of Sanwood Test Chamber

The two-zone thermal shock test chamber is designed with two independent control rooms, one for low temperature and one for high temperature. The product is quickly transferred back and forth between the high and low temperature zones, allowing the product to withstand severe temperature changes in a short period of time.

• The temperature recovery time period is short, and two temperature systems have achieved rapid sample temperature recovery time (less than 15 minutes).

• It is in compliance with IEC 60068-2-14 Na and IEC 61747-5 testing standards.

• Excellent temperature uniformity: The average airflow within the testing area generates an outstanding temperature distribution.

• The chamber can be controlled and monitored remotely by mobile phones, tablets, and PCs.

• Can customize the chamber’s volume, temperature, and appearance on demand.

• Operating system with multi-language support.

Application Fields

The two-zone thermal shock test chamber is widely used for product testing in various fields such as electronics, electrical appliances, mobile phones, communications, instruments, vehicles, plastic products, metals, food, chemistry, building materials, medical, aerospace, etc.

Test Standards

The testing standards for the two-zone thermal shock test chamber usually vary depending on the industry and product. The following are some common standards and specifications:

• IEC 60068-2-14: Environmental testing – Part 2: Test methods – Test Na: Rapid change of temperature.

• IEC 61747-5: Liquid crystal display devices – Part 5: Environmental test methods.

Control System

The control system of the Sanwood test chamber adopts the world’s leading software and hardware system to ensure that the test chamber operates under preset conditions, provides accurate and reliable experimental data, and helps users achieve precise control and data collection of various experimental conditions.

• Controller: It adopts the controller imported from South Korea Sanwon and the self-developed control system, which can be equipped with Siemens control system and equipped with RS232, RS485, and Ethernet communication ports.

• Programmable control: It supports setting experimental programs, such as heating, cooling, constant temperature time, etc., and can execute multiple program settings, and supports advance reservation startup function.

• Multiple languages are available: English, Korean, Chinese, and Japanese.

• Remote monitoring: Using SAMWON-EZNET network remote technology to achieve remote control, the test chamber can be monitored at any time, and the current data can be viewed through the user’s PC and mobile phone, which improves the convenience of testing.

Refrigeration System

The refrigeration system of the test chamber is a complex and important system. The stability of the refrigeration system is crucial to the accuracy and reliability of the test results.

• Sanwood Technology has developed a refrigerant hot gas defrosting technology, which effectively melts the frost on the evaporator by injecting high-temperature and high-pressure refrigerant steam into the heat exchanger in the test chamber. This not only ensures that the evaporator does not frost but also greatly reduces the energy consumption of the equipment.

• The refrigeration unit adopts an internationally renowned brand. In cooperation with Japan’s Saginomiya and the United States’ Sporlan, the EPV series and XUP series energy-saving system quick-opening solenoid valves have been developed, with an all-weather service life of more than 15 years.

• Optimize the layout of the refrigeration system and adopt VRF (refrigerant flow control) technology based on the PID cold end output principle to achieve low-temperature energy-saving operation, which can reduce energy consumption by 30% under low-temperature conditions.

• The refrigeration system adopts a modular design, with low failure rate, few welding points, high refrigeration efficiency, good reliability, simple maintenance, and low maintenance cost.
