A chamber performs only as well as the requirement behind it. Most problems on a reliability test line — a profile the chamber cannot reach, a specimen that runs hotter than expected, an enclosure one size too small — trace back to a parameter that was never pinned down before the order. The engineering review is the step where we pin it down.
Send us the information below and our engineers check it against the chamber series. You get back a configuration and the performance figures that follow from it. The review is free of charge and carries no obligation to order.
Information we need
| Item | What to send | Why it decides the design |
|---|---|---|
| Test standard | IEC 60068-2-1, IEC 60068-2-2, IEC 60068-2-30, IEC 60068-2-78, GB/T 2423, GJB 150, MIL-STD-810, JEDEC JESD22, ISO 16750-4, or your own internal procedure | Sets the profile, the ramp rate and the tolerances the chamber has to hold |
| Chamber type | Temperature-humidity, thermal shock, rapid temperature change, walk-in, altitude / low pressure, thermal vacuum, HALT/HASS, ESS, salt spray, dust | Narrows the series before anything else is discussed |
| Temperature range | Lowest and highest temperature required at the specimen, in °C | Fixes the refrigeration stage (single stage, cascade, or cold-source cooling) |
| Humidity range | % RH required, and whether a dew point step or a dry-out step is included | Decides whether humidification, dehumidification and a water supply are needed |
| Internal dimensions | Required working space in W × H × D mm, or the specimen envelope plus the clearance you want around it | Sizes the chamber and sets airflow and uniformity |
| Specimen load | Mass in kg and, more importantly, heat dissipation in W while the test runs | A live load adds heat the refrigeration has to remove; this is the parameter most often left out of an enquiry |
| Low pressure / vacuum | Target absolute pressure (Pa, kPa or mbar) and whether altitude simulation is required | Decides the pump train, the chamber construction and the sealing |
| Power supply | Voltage, phases and frequency available at the installation site (for example 380 V, 3-phase, 50 Hz) | Decides heater and compressor configuration |
| Site | Country, ambient conditions, and availability of cooling water and compressed air | Affects the cooling scheme and the documentation |
| Specimen | What is tested: PCB and components, module, battery or cell, optical assembly, structure | Drives fixture design and safety measures |
How the review runs
- Requirement intake. You send the list above. A table, a drawing, a standard reference or a test specification all work. If something is missing we ask for it rather than assume it.
- Feasibility check. We compare the requirement with the published range of each series and identify where the request falls outside a standard model.
- Configuration. We propose a series and model and state the figures that come with it: temperature range, ramp rate, uniformity, humidity range, vacuum level, load capacity.
- Documentation. You receive the configuration, the site and utility requirements, and the standards the chamber is designed against.
- Confirmation and production. Once the parameters are agreed, the chamber goes to production with the reviewed figures attached to the order.
Engineering capability
- Thermal design. Air circulation and uniformity work, plus heating and refrigeration staging for the ramp rate the profile needs.
- Refrigeration. Single-stage and cascade systems, cold-plate and cold-source cooling for the low-temperature end.
- Vacuum. Pump train selection, chamber sealing and outgassing control, pressure regulation over several ranges.
- Control. PLC and PID control, programmable profiles, data logging and remote monitoring.
- Fabrication. Sheet metal, insulation, pipework and vacuum assembly in-house, with calibration and performance verification before shipment.
What you get back
- A recommended model and configuration for your requirement
- Temperature, humidity and, where applicable, vacuum performance figures
- The utility and site requirements for installation
- The standards and test procedures the chamber is designed to run
