SANWOOD TECHNOLOGY Temperature humidity test chamber ( Dual 85 Testing ): Creating Reliable Testing Solutions for Low Altitude Economy Fields

In today's booming low-altitude economy, UAVs, eVTOLs and other low-altitude vehicles are gradually being used in many fields such as logistics and transport, emergency rescue, agricultural plant protection, urban air traffic and so on. However, extreme high and low temperatures, humidity and heat conditions pose serious challenges to the materials, electronic components, battery systems, etc. of the aircraft. With advanced temperature and humidity control technology, excellent stability and intelligent design, SANWOOD's Temperature humidity test chamber ( Dual 85 Testing ) has become the core equipment for environmental adaptability testing in low-altitude economic field.

Extreme environment simulation

Low-altitude aircraft in real operation may face -40 ℃ extreme cold, 60 ℃ high temperature, 95% RH high humidity environment, and even need to adapt to high altitude and low air pressure conditions. SANWOOD’s Temperature humidity test chamber ( Dual 85 Testing )  can accurately simulate these harsh environments, and conduct ‘double 85 test’(85℃, 85%RH), high and low temperature cycle, humidity and heat aging tests on the UAV, battery, flight control system, sensors, and other key components, so as to quickly expose potential defects and optimize the product design.

Technical parameters

Temperature range: -70 ℃ ~ +180 ℃ 

Humidity range: 20.0%RH ~ 98.0%RH (60 ℃ or more corresponds to 20%RH) 

Temperature fluctuation: ± 0.5 ℃ 

Temperature uniformity: ≤ 1.5 ℃ (-40.0 ℃ ~ +100.0 ℃) 

                                        ≤ 2.0 ℃ (+100.1 ℃ ~ +180.0 ℃ or -40.0 ℃ ~ -70.0 ℃)

Temperature fall rate: +180.0°C~-70.0°C within approx. 100 min 1.0~3.0°C/min 

Temperature rise rate: -70.0°C~+180.0°C within approx. 60 min 3.0~5.0°C/min 

Note: The performance data is given at an ambient temperature of +23°C, a relative humidity of 65±20%rh, a rated voltage and no samples in the test area under the circumstances given; ambient temperature of 0 ℃ to +30 ℃ when the minimum temperature can be achieved.

Equipment features

1.Advanced cold balance control mode and PD regulation technology, greatly reducing the energy consumption of the equipment.

2.After the end of the programme, the machine has the function of returning to normal temperature automatically for the protection of the specimen.

3.With good sealing to ensure that the machine can run for a long time (more than 1000 hours) without frost.

4.Using a unique air circulation design to ensure that the top of the studio even in hot and humid mode, will not produce dripping dew.

In line with test standards 

In the R & D and airworthiness certification process of low-altitude aircraft, the environmental adaptability test must comply with international standards to ensure the authority of the data. SANWOOD’s Temperature humidity test chamber ( Dual 85 Testing ) strictly follow the IEC60068-3-5:2001 standard, to ensure that the temperature and humidity control accuracy, uniformity and stability to meet the stringent test requirements.

SANWOOD's Temperature humidity test chamber ( Dual 85 Testing ) not only meets the IEC60068-3-5:2001 standard, but also combines the double 85 test (85℃/85%RH) and temperature shock test to provide comprehensive reliability verification for UAVs, eVTOLs, and on-board equipment, and help enterprises accelerate the process of airworthiness certification.

SANWOOD is committed to providing efficient and reliable test support for customers in the low-altitude field, helping to improve product performance and safety certification. Our Temperature humidity test chamber ( Dual 85 Testing )  can help enterprises to quickly complete the high and low temperature storage, humidity and heat aging test and other verification, significantly shorten the research and development cycle, for airworthiness certification to provide strong data support.
