Climats

What Climats does

Climats is a French manufacturer of customizable environmental test chambers, founded in 1974–1975 and headquartered in Martillac near Bordeaux, operating from a 10,000 m² production facility as a wholly-owned subsidiary of Weiss Technik France. The company designs and builds equipment that simulates temperature, humidity, thermal shock, and combined vibration-temperature conditions for product reliability testing and validation, with offerings ranging from compact 55-liter units to walk-in and modular chambers exceeding 100 m³. The portfolio includes the EXCAL3 next-generation platform (200 models across 8 volumes with 80+ personalization options), the WINCAL walk-in chamber series, the SCAL thermal shock family (CTR, CTK, CTH2, CTH3/CTY, CTZ/CTHZ variants), CM modular chambers for large specimens, ViBt/ViBav/ViBp combined vibration-temperature systems, and the Double Door EE type for large product loading. All products are controlled through SPIRALE, a proprietary touchscreen interface with three user levels, multi-language support, programmable test profiles, and an Energy Saving mode delivering at least 40% electricity reduction.

The company's revenue model combines one-time equipment sales of custom-built chambers with a recurring maintenance and after-sales service stream and a usage-based rental offering for standard EXCAL equipment during delivery gaps or one-off campaigns. Pricing is quotation-based and driven by customer specifications rather than published list prices. Climats serves eight primary verticals: aerospace, space, mobility (including electric vehicles), testing laboratories, electronics and connectivity, defense, telecommunications, and green energy and storage. The go-to-market is sales-led B2B, relying on direct customer engagement through expert consultation appointments, downloadable technical documentation, a bilingual French/English website with newsletter subscription, and an international distribution network that supports customers globally from the single French manufacturing base.
