GBPI OTH-150DJ – Temperature & Humidity Test Chamber (Programmable Climatic Aging)

The GBPI OTH-150DJ is an advanced, high-precision programmable temperature and humidity test chamber engineered to simulate severe environmental extremes, cyclical thermal shocks, and elevated moisture exposure for flexible packaging substrates, electronic assemblies, medical devices, automotive components, and composite polymers. Manufactured in strict conformity with universally recognized environmental durability standards—including IEC 60068-2-1 (cold testing), IEC 60068-2-2 (dry heat), ASTM D4332 (conditioning containers and packages), and GB/T 2423—this climatic cabinet provides certified environmental reliability testing.

Materials and consumer packaging distributed across global shipping lanes encounter radical climatic transitions, from sub-zero refrigerated air freight to sweltering tropical humidity. Prolonged climatic exposure can cause adhesive delamination, seal embrittlement, barrier loss, polymer crazing, or warping. Operating as a heavy-duty temperature and humidity test chamber, the OTH-150DJ subjects test specimens to tightly controlled, reproducible hydrothermal conditions to accelerate physical aging and validate product shelf life before commercial distribution.

Advanced Cascade Refrigeration & Humidification

The system incorporates a robust French Tecumseh hermetic compressor setup utilizing environmentally safe refrigerants to achieve rapid chilling down to -40°C. Humidification is delivered via an external stainless steel steam generator coupled with precision electronic capacitive humidity sensors, maintaining relative humidity levels across 20% to 98% RH with fluctuations limited to ±2.5% RH throughout long-term continuous cycles.

Programmable Touchscreen PLC Architecture

Controlled via a prominent 7-inch color graphic human-machine interface, the microprocessor supports up to 120 custom programs with 1200 ramp and soak segments. Operators can program complex real-world diurnal temperature cycles, thermal shock transitions, or long-term ICH stability trials with real-time curve plotting and USB data export.

Widely utilized by pharmaceutical packagers, food science laboratories, aerospace electronics firms, and packaging converting plants, the OTH-150DJ guarantees dependable climatic simulation for mission-critical quality validation. The heavy-gauge structural insulation prevents condensation on external cabinetry, while balanced internal airflow louvers eliminate thermal dead zones across all specimen placement tiers.
