Cold-Hot Balance Technology cuts waste from temperature overshoots. Conventional systems overheat, then overcool, running both at once—wasting power. Costs can near new equipment prices in years.

TestEQ uses smart algorithms to balance heating and cooling precisely. This maintains stability while slashing energy use by up to 49%, saving costs and boosting sustainability.

Development Milestones
2011

Established in Dongguan, Pearl River Delta, China.

2012

Collaborated with Tsinghua University Shenzhen Research Institute on R&D for non-standard testing equipment in simulated environments through industry-university-research partnerships.

2013

Produced China’s first highly accelerated aging test chamber, filling the domestic gap in three-axis six-degree-of-freedom test chambers.

2014

Partnered with the Air Force Equipment Research Institute to develop ultra-low-temperature rapid temperature cycling test chambers. Collaborated with Guangdong Quality Inspection Center to create annular wind-speed test chambers, achieving ±5% uniformity in temperature-humidity-wind control.

2015

Jointly developed a 54 m³ explosion-proof rapid temperature cycling low-pressure test chamber with Jianghang Aircraft Equipment. Collaborated with the China Academy of Engineering Physics on a high-low-temperature humidity-pressure test chamber for simulating underwater and high-altitude environments.

2016

Developed China’s first domestically produced temperature-humidity-altitude multi-stress coupled test chamber (21,000-meter altitude control), reaching world-class standards. Expanded into breakthrough cloud-layer simulation chambers, rapid-freezing cold-rain test chambers, and fast-icing test chambers.

2015/2017/2021

Awarded "National High-Tech Enterprise" certification three times consecutively.

2018

Received the Guangdong Provincial Innovation Award for Technology-Based SMEs.

2019

Developed China’s largest crossbeam multi-unit high-low-temperature low-pressure test chamber (6,300 mm crossbeam length, 120 m³ capacity) for State Grid.

2020

Collaborated with Beijing Qingyun Aviation to create China’s first mechanical explosion test chamber (integrated temperature-humidity-altitude functionality with explosive decompression).

2021

Partnered with the Chinese Academy of Sciences to develop an 18-meter optical thermal vacuum chamber with a 3.5-meter heat sink.

2023

Co-developed a 1,700 m³ multi-chamber rapid temperature cycling test chamber with Beijing Lantian Group.

2024

Collaborated with China FAW Group (Changchun) to create an electric drive reliability HALT test platform.

2025

Has been awarded the "Dongguan Intelligent Environmental Test Chamber Engineering Research Center" “AAA-level Credit Enterprise for Enterprise Credit Evaluation”“Guangdong Province Technology-based Small and Medium-sized Enterprise”“Carbon Neutrality Commitment Demonstration Unit”
