    (0°C/-40°C/-70°C~+120°C optional) can be customised ~+180°C
    A type: 0°C
    C type: -40°C
    D type: -70°C

    This high-capacity, professional Climate Chamber is the ultimate solution for precise, large-scale, and continuous reliability testing. Engineered for comprehensive R&D, Quality Assurance, and production-level testing, it is the most suitable choice for demanding applications involving high volumes of electronic components or larger finished products. Its robust construction, high-volume capacity, and cutting-edge intelligent features ensure reliable and efficient testing every time.

    Ideal for High-Volume and Large-Scale Testing

    Our floor-standing chamber is designed to simulate the demanding environmental conditions components and finished products face during their lifecycle. Use it for critical and continuous reliability testing of:

    • High-volume production batches

    • Large electronic assemblies and systems

    • Automotive parts and modules

    • Aerospace components

    • Advanced semiconductor devices

    • Materials and finished products requiring significant testing space

    Test for adaptability in severe high and low temperature alternating and humid and hot environments with high volume and high stability.

    Versatile Capacity Range

    • Model Options: Labec Temperature & Humidity Chambers are available in a wide range of sizes, from 100 litres up to 2000 litres capacity, ensuring a model is available to meet every scale of testing requirement.

    Advanced Refrigeration System

    • Superior Efficiency: Features a high-efficiency refrigeration system engineered for maximum reliability while ensuring low vibration and low noise output.

    • Eco-Friendly and Safe: Utilises an air-cooled system operating with CFC-free refrigerant, adhering to modern environmental standards.

    • Optimised Compressor Life: The cooling circuit incorporates a solenoid valve bypass technique. This smart control ensures the compressor remains connected unless cooling capacity is not required for a prolonged period, significantly enhancing the compressor’s lifespan and stability.

    Precise Heating System

    • Fast Response Heating: Heating is achieved using a low mass electric resistance heater strategically located directly in front of the re-circulating air blower for rapid and uniform temperature distribution.

    • Constant Control: Temperature stability is guaranteed by PID microprocessor controllers utilizing solid state relays (SSR), allowing for extremely precise and constant control of the heating process.

    Key Product Features

    1. High Capacity and Smart Efficiency

    • High Volume Testing: Floor-standing design offers significantly greater internal volume, accommodating large parts or high-volume component batches for production-level stress testing.

    • Intelligent Energy Savings: Utilises the latest intelligent (refrigeration & dehumidification) system, delivering 30-45% greater electricity savings compared to traditional high-capacity testing machines.

    • Durable & Professional Build: Robust construction designed for continuous industrial use in professional laboratory and manufacturing environments.

    2. Advanced Control and Seamless Operation

    • Intuitive Touch Control: Operate the unit via a high-definition, colour LCD touch screen. Users can display complex operating data, freely set detailed test parameters, and save extensive test profiles for consistent quality checks.

    • Remote Management: Stay connected and in control regardless of your location. The chamber can be managed remotely via LAN or USB port, allowing control and monitoring from a connected computer or mobile phone.

    3. Data Integrity and Safety Standards

    • Comprehensive Data Output: Equipped with a dedicated data collection and storage interface. Easily output your extensive test results into clear graphics and accessible Excel data tables for simple trend analysis, detailed reporting, and compliance documentation.
    • Independent Safety System: An integrated temperature limit alarm system ensures operational safety. It automatically interrupts testing if the temperature exceeds pre-set limits, protecting the chamber, valuable test materials, and personnel.
