EziLab supplies the Temperature Test Chamber EZL-TC155 for aerospace laboratories that need the same extreme -70°C to 150°C range as the 420L aerospace unit in this catalog, at a smaller 235L capacity with cascade refrigeration and touchscreen control. This humidity chamber uses cascade refrigeration to reach and hold the -70°C floor, a two-stage cooling system that achieves deeper sub-zero temperatures more efficiently than a single-stage compressor could manage at that extreme, which matters for sustaining genuinely cold-soak conditions throughout extended aerospace test cycles rather than just briefly touching the low end. The 235L capacity gives aerospace programs a smaller-footprint option for component-level cold-soak and thermal cycling testing where the full 420L chamber's larger volume isn't needed for the specific components under test, while still reaching the same extreme temperature range that ground-based industrial chambers don't cover. Touchscreen control simplifies programming the multi-stage ramp profiles extreme-range aerospace testing typically requires compared to older dial-based interfaces. Aerospace component testing programs needing extreme cold-soak capability at a smaller batch scale than full-assembly testing requires get the same temperature range as the larger unit in a more space-efficient chamber. See the Humidity Chamber and Temperature Test Chamber ranges for extreme-range aerospace testing needs across USA aerospace laboratory settings.
