Programmable Climatic Chambers for Precision Environmental Cycling
Simulate extreme temperature and humidity transitions to expose design flaws and meet strict IEC/MIL-STD compliance
Unlock Dynamic Reliability with Climatic Cycling
Constant temperature and humidity testing is excellent for baseline material aging,Our programmable temperature and humidity chambers introduce controlled thermal ramps (1~3℃/min) and dynamic moisture cycles to accurately simulate day-to-night transitions and seasonal extremes, revealing structural vulnerabilities that only appear under fluctuating stress.
Validate IP Seals Against the "Breathing Effect"
Simulating rapid day-to-night temperature drops in high-humidity environments.
Why You Must Test:
As outdoor enclosures (like 5G routers or EV batteries) cool rapidly at nightfall, the internal air contracts. This creates a vacuum that literally sucks external moisture past your waterproof seals—a phenomenon known as the “Breathing Effect.” Alternating damp-heat testing forces this exact scenario, ensuring your IP67/IP68 seals won’t leak internal condensation in real alpplications.
Expose Thermal-Mechanical Fatigue
Continuous, alternating hot-and-humid to cold-and-dry climatic cycling
Why You Must Test:
Materials absorb moisture and expand when heated, then rapidly contract during cold cycles. This relentless “push and pull” creates severe mechanical stress that shears PCB solder joints, delaminates solar composites, and causes micro-cracks in plastic housings. Our JCT environmental test chamber executes these precise thermal transitions to help you pinpoint the exact fatigue limits of your assemblies before mass production.
Automate Strict IEC & MIL-STD Compliance
The Application: Running multi-step, programmable environmental profiles (e.g., IEC 60068-2-38, GB/T 2423.34).
Why You Must Test:
If Entering Tier-1 automotive, aerospace, or military supply chains,they require highly specific cyclic testing to mimic actual flight paths or cross-continental shipping environments. We can controll automate these complex alternating standards perfectly by PID, generating the dynamic, traceable reliability data you need .

Core Technology
The 4-System Dynamic Balance
Our Constant Temperature and Humidity Chamber maintain perfect environmental equilibrium through a dynamic interplay of 4 subsystems.Electric heating wires elevate temperatures,Imported mechanical compressors drive refrigerants to cool the zone.Steam generator injects precise water vapor for humidification, and the evaporator’s condensation effect will strip moisture from the air for dehumidification.A heavy-duty centrifugal fan forces this conditioned air into every corner of the workspace, completely eliminating dead zones.
Precision PID & PT100 Sensors
The core of our environmental test chambers lies in algorithmic control. High-precision PT100 platinum resistance sensors acutely capture the slightest thermal or moisture deviations. The smart PID controller instantly calculates and commands micro-adjustments across the heating and cooling systems, allowing the chamber to run continuously for months with ultra-low fluctuations (±0.5℃, ±2.0%RH).
Applications
Automotive manufacture
When vehicles are exposed to the outdoors for extended periods, they must endure both the scorching summer storms and the bitterly cold winter nights. These fluctuating weather conditions can trigger the “breathing effect” in headlight assemblies, causing moisture to be drawn in and resulting in severe internal condensation. Additionally, sudden drops in temperature can cause rubber seals to harden, forcing moisture to seep into the instrument panel display or the battery management system (BMS) module, which can lead to touchscreen malfunctions. Our JCT temperature and humidity cycling test chamber can precisely simulate these alternating extreme environments, allowing you to verify the sealing integrity and anti-condensation reliability of your automotive components during long-term use.
electronics
Outdoor 5G base stations and smartphones have been deployed in regions around the world prone to extreme weather conditions. Fluctuations in high-humidity environments have long been the primary cause of conductive anode filament (CAF) growth and ion migration on high-density PCBs, leading to catastrophic micro-short circuits. In addition, temperature changes can cause the optically clear adhesive (OCA) in displays to bubble or delaminate. By running programmable high-low temperature cycling test chamber, you can evaluate the moisture sensitivity level (MSL) and prevent these moisture-induced hardware failures.
.Semiconductors & Precision Components
Epoxy molding compounds used in integrated circuit packaging naturally absorb moisture during warehouse storage. If a chip undergoes surface-mount reflow soldering (at temperatures exceeding 260°C) while in a saturated state, the trapped water vapor will instantly vaporize and expand. This extreme internal pressure can sever the lead bonds and shatter the package housing—this is the catastrophic “popcorn effect.” Our alternating climate test chamber precisely measures the rate of moisture absorption by performing rigorous pre-humidification and moisture absorption/desiccation cycles, thereby preventing catastrophic losses on the assembly line.
Photovoltaics & Energy Storage
Solar panels are designed to have a service life of 25 years and must withstand intense daytime UV radiation and high temperatures outdoors, followed by freezing nights. This relentless cycle of heat, humidity, and freezing causes the EVA encapsulant to degrade, leading to yellowing and delamination of the back sheet. Once the moisture barrier fails, water intrusion triggers potential-induced degradation (PID), resulting in a sharp decline in power output. Our programmable temperature and humidity test chamber can automatically perform 1,000 hours of rigorous freeze-thaw cycling tests (in accordance with the GB/T 9535 standard) to ensure the long-term reliability of grid-connected solar power systems
Aerospace & Military
The aircraft rapidly transitions from the humid, hot ground environment into the cold, low-pressure stratosphere. This drastic environmental change acts like a pump, forcing atmospheric moisture deep into the sealed radar compartment and avionics equipment. The resulting condensation can instantly disable sensitive RF transceivers and severely corrode radar waveguides. Our environmental test chambers can automatically execute rigorous MIL-STD-810G and GJB 150 cyclic test protocols to verify that military hardware operates normally under these simulated extreme flight profiles.
Polymers & Surface Coatings
Industrial coatings and electroplated metal parts are constantly subjected to thermal expansion and contraction. This thermal expansion and contraction causes microscopic pores in the coating to physically expand. When alternating cycles of heat and humidity allow moisture and oxygen to penetrate the metal substrate through these expanded pores, rapid electrochemical corrosion is triggered. Our programmable high-low temperature cyclic humidity test chamber effectively accelerates this blistering and peeling process, allowing you to validate corrosion-resistant formulations and adhesion strength in a matter of weeks rather than years

FAQ
Q1: What exactly is an alternating climatic test chamber, and what does it do?
It’s a specialized, programmable oven and refrigerator combined, with a built-in humidifier. Instead of just holding one temperature, it automatically cycles between extreme heat and freezing cold, while adjusting the humidity, to mimic the complex weather patterns your product will face in the real world
It provides an extremely stable and uniform artificial environment for the test specimens.
Its core function is to simulate long-term climatic stresses found in nature by maintaining (or alternating) specific temperature and humidity parameters over extended periods (such as the classic “double 85” test: 85°C, 85% RH).
.
Q2: Why do I need to test my products in one of these chambers?
If you ship your products globally, they might sit in a freezing warehouse in Canada and then be used in the humid heat of Singapore. This climatical chamber exposes hidden weaknesses—like glue peeling, circuits shorting, or screens fogging—before your products reach your customers, saving you from expensive recalls and damaged brand reputation.
Constant temperature and humidity chamber focuses on steady-state long-term stability with gradual temperature transitions.
In contrast, rapid rate thermal cycle chambers or thermal shock chambers ）inflict rapid thermal expansion stress using extreme ramp rates (e.g., 15°C/min to instantaneous transfer).
Q3: Do I need the R (-20℃), T (-40℃), or U (-70℃) series?
For consumer electronics, R (-20℃) is usually sufficient.
Automotive and outdoor telecom require T (-40℃).
If you are testing aerospace, military, or extreme winter equipment, you must use the U (-70℃) series.
Q4: Can I export the thermal cycling data for compliance reporting?
Yes.
The system continuously logs the set value (SV) versus the actual present value (PV). You can export these precise graphs and data logs directly via USB or RS485 for your GB/IEC compliance audits.
Q5: What is the lead time for one of the 1000L chamber models?
Standard configurations of the JCT-TH-AS-100 or SS-4 series (1000L) typically ship in 20-25 days. Submit your specific payload and temperature range below for a precise manufacturing timeline.
