Climate chamber THR

thermostatichumiditytemperature

Overview
The THR Series walk-in temperature and humidity environmental test chamber is a customizable climate room for accelerated temperature and humidity testing of large parts and whole products, including PV solar panels, electronics, automotive components, LED systems and appliances. The system combines temperature and humidity control, programmable profiles, multiple safety protections and on-site installation support.

Series / Identity
THR Series — Temperature Humidity Room

Key Benefits

• Internal dimensions customizable to fit the DUT and lab layout, enabling whole-product tests without disassembly.
• Six selectable low-temperature grades (A–F) down to −70 °C; standard high temperature to 80 °C with optional extension to 150 °C.
• Integrated temperature and humidity control in a walk-in format for representative environmental testing of full-size assemblies.
• Multiple independent protection layers for sample, operator and system safety.
• Programmable test profiles and USB data export for reporting and traceability.

Features (What This System Delivers)

• Full customization — room size and internal layout built to customer specifications.
• Temperature coverage — six low-temperature grades (A–F) to −70 °C; optional high-temperature capability to 150 °C.
• Access and handling — walk-in door and cart-compatible design for easy loading of panels and assemblies.
• Safety — redundant protections: power, motor, compressor, heater, water shortage, over-temperature and over-humidity alarms.
