Air conditioning unit for a climatic chamber

The Air conditioning unit for a climatic chamber complies with multiple international and industrial standards, including IEC 60068, MIL-STD-810, ASTM D4332, ISO 16750, AAMA501, and automotive, aerospace, and electronics-specific regulations. Its customizable workroom sizes range from 100 L to 1000 L, allowing testing of small electronic components, industrial assemblies, and even large automotive or aerospace specimens. The chamber is suitable for environmental reliability testing, thermal cycling, material aging studies, electronics evaluation, and pharmaceutical stability testing, ensuring consistent and repeatable results across industries.

Performance Advantages

1. Independent Power Components for Maximum Stability: The compressor, condenser, and heating units are completely separated from the workroom, preventing heat, vibration, and airflow interference with the test specimens. This design ensures that sensitive electronics, batteries, and precision instruments experience true environmental conditions without distortion, maintaining accurate temperature and humidity readings throughout long test cycles.

2. Rapid Thermal Response for Efficient Testing: Equipped with high-power heating elements and a mechanical compression refrigeration system, the chamber can quickly adjust temperature between –70 °C and +150 °C. Fast ramp rates (3 °C/min heating, 1 °C/min cooling) allow accelerated thermal cycling and stress testing, reducing overall test duration while still maintaining stability and uniformity for reliable results.

3. Quieter Laboratory Operation for Comfortable Use: By positioning the power units outside the main workroom, the chamber operates at ≤65 dBA, significantly lower than conventional integrated chambers. This low noise environment allows laboratory staff to conduct concurrent experiments, data analysis, or monitoring without distraction, making it ideal for shared laboratories, R&D spaces, or cleanroom conditions.

4. Compact Footprint and Flexible Installation: The split-type design allows the workroom to be installed in constrained laboratory spaces while the larger external components can be located elsewhere. With internal volumes ranging from 100 L to 1000 L and customizable workroom dimensions, laboratories can efficiently test small modules, mid-sized components, or full-size assemblies without compromising floor space. The modular layout also facilitates easy transportation, installation, and future upgrades.

5. High Accuracy and Environmental Uniformity: Utilizing PT100 Class A temperature sensors with 0.001 °C resolution and optimized airflow through centrifugal fans, the chamber maintains precise environmental conditions with ±0.5 °C temperature fluctuation and ±2.5 % RH humidity deviation. The uniform airflow design eliminates hotspots or condensation zones, ensuring that all test specimens receive consistent conditions for reliable and reproducible data.

6. Robust Construction with Integrated Safety Protections: The interior SUS304 stainless steel and reinforced steel exterior provide exceptional corrosion and mechanical resistance in high-humidity and extreme temperature environments. Comprehensive safety features include over-temperature protection, over-current monitoring, water shortage detection, refrigerant high-pressure protection, and earth leakage prevention. These safeguards protect both personnel and samples, allowing 24/7 operation with minimal supervision and long-term reliability.

Operating Parameters of the Air Conditioning Unit for a Climatic Chamber  

Typical Tests Performed 

The Air conditioning unit for a climatic chamber can perform thermal shock cycling from –40 °C to 85 °C, thermal endurance testing between 0 °C and 70 °C, high- and low-temperature exposure at 85 °C and –20 °C, damp heat and humidity testing up to 95 % RH, shelf-life evaluation at 25 °C and moderate humidity, and hydrolysis aging tests between 20 °C and 70 °C. Continuous monitoring ensures reliable and repeatable results. For example, a test could cycle a battery pack from –20 °C to 100 °C at 3 °C/min with 80 % RH to evaluate thermal stability.

FAQs

Q1: Can the chamber achieve faster ramp rates, such as 20 °C/min?

A1: Standard ramp rates are 5–10 °C/min, but custom configurations can achieve 20 °C/min or higher to meet specific requirements.

Q2: Does it include audible or visual alarms?

A2: Audible alarms are standard. Visual alarms can be added optionally and configured to meet customer needs.

Q3: Will custom test ports or viewing windows delay delivery?

A3: Standard adjustments do not affect lead times. Fully custom optical windows may add 5–10 days, and LIB manages production to ensure timely delivery.
