Fast Temp Change Temperature and Humidity Tester KTB Series is designed for all kinds of electrical and electronic products and other products, parts and materials for high and low temperature constant and gradual change, sudden change, hot and humid test and other environmental simulation reliability test.
Accelerated Environmental Stress Screening Powered by 12°C/min Linear Ramping Precision.
The ITM-LAB KTB Series is a high-performance, water-cooled rapid temperature change testing chamber engineered for rigorous Environmental Stress Screening (ESS) and reliability profiling. Purpose-built to subject aerospace electronics, automotive components, and semiconductor modules to extreme thermal shock and gradual stress variation, the KTB series delivers adjustable linear ramping rates up to 12°C/min across a broad dynamic spectrum from -55°C to +125°C.
Utilizing an advanced Balanced Temperature and Humidity Control (BTHC) system paired with elite German semi-hermetic refrigeration trains, this series eliminates thermal overshoot while cutting redundant energy consumption during steady-state soak periods. Fully compliant with international testing protocols including IEC60068-2-14, IEC60068-2-1, and IEC60068-2-2, it provides uncompromised data logging for mission-critical engineering labs.
❄ High-Ramp Thermal Train: Driven by twin German semi-hermetic compressors running eco-friendly DuPont HFC R404A/R23 refrigerants, supported by Danfoss expansion valves and a heavy-duty Emerson oil separation loop.
🌀 Zero-Overshoot Airflow Dynamics: Features dual 1HP Taiwanese TECO circulation motors paired with multi-blade centrifugal aluminum alloy fans to enforce uniform top-delivery and bottom-return climate mapping.
📊 Intelligently Automated BTHC Modality: The system automatically shifts refrigerant flow velocities based on real-time loads, completely turning off excess cooling stages during constant phases to optimize power consumption.
🛡 Multi-Tiered Fail-Safe Security: Outfitted with independent Omron over-temperature protectors, German Schneider electromagnetic safety switches, automated phase-loss barriers, and live specimen power-off interlocks.

The KTB Series is managed by a high-precision 7-inch TFT true-color resistive touchscreen interface featuring deep paperless data logging and remote diagnosis networks:
Massive Program Capacity: Supports storage for 100 separate program groups containing up to 1,000 distinct segments, allowing complex nested profiling and free program interlinking up to 20 steps.
Automated XLS Data Export: The built-in memory captures 24-hour runtime curves continuously for 300 days, outputting directly to localized USB ports as natively readable Excel spreadsheets.
Remote Browser Diagnosis: An integrated LAN network interface enables central monitoring of up to 16 chambers simultaneously. Technicians can securely log in via any standard web browser using the machine's dedicated IP address to review fault logs and runtime data remotely.
The hardware and control loops are pre-configured to execute specialized simulation programs in strict accordance with global test criteria:
IEC 60068-2-14 (Test N): Rapid change of temperature with prescribed linear ramp profiles.
IEC 60068-2-1 / IEC 60068-2-2: Steady-state low temperature and high temperature operational endurance assessments.
To guarantee nominal performance at peak 12°C/min ramp loads, your facility must accommodate the following logistics:
Power Distribution: Three-Phase 5-Wire AC 380V (±10%), 50Hz with a dedicated ground resistance ≤ 4Ω, utilizing a 3P+N 250A leakage isolation switch.
Integrated Water Auxiliary Chiller (Model JLSF-10HP Included): Features an independent 10HP fully enclosed scroll compressor loop delivering a nominal cooling capacity of 31 kW to maintain optimal condensation heat exchange.
Humidification Feed: Clean water input line requiring a minimum water resistivity ≥ 500MΩ.
