Low Temperature (& Humidity) FM Chamber

This is the successor model to
Faster Temp. (& Humid.) Chamber SM series and
Low Temp. (& Humid.) Chamber FM series.

The FD series is desirable for testing large assemblies and completed products such as lithium-ion battery modules, EV powertrain, PV modules and avionics components, etc.
The right solution to meet your applications and various test standards such as MIL, ISO, IEC, and LV 124.

  • Size variations are available in the range from 1m3 to 12m3, depending on your application.
  • Additional safety features are also available for the LiB tests.
  • Tests in-situ or full-size samples are possible even for EV powertrains and instrument clusters, not requiring you to prepare test coupons or reduce-size test pieces.
  • Photovoltaic modules durability, reliability tests according to IEC/JIS standards.
  • Ideal for secondary battery charge / discharge testing with inner size flexible design.

Temperature change rate (Reference example) -18°C ⇔ 158°C 3°C/min or more
(No specimen, average, during the test -40°C ⇔ +180°C)
-45°C⇔155°C 3°C/min or more
(No specimen, average, during the test -70°C ⇔ +180°C)

※Temperature change rate shown above are a reference case. This may not be possible due to the internal volume.

* We can meet various customers requirements by combining temperature and humidity performance with the chamber dimensions shown above.

*1 Excluding partial protrusions.

* The specifications will be adjusted according to customer requirements for the thermal cycle test (IEC 61215 10.11, JIS C 8990), humidity freeze test (IEC 61215 10.12, JIS C 8990), and damp heat test (IEC 61215 10.13, JIS C 8990).

* This series supports hot-spot testing when combined with a solar simulator.

* These models can also support DML testing (IEC 61215 10.16, JIS C8990) when combined with the mechanical load test.
