Climate chamber THR

humiditytemperaturethermal shock

Summary
Programmable walk-in climatic test chamber for EV Charger: designed to test heat resistance, cold resistance, dry heat and damp heat. Suitable for quality control in electronics, electrical equipment, automotive, metals, food, chemical, construction materials, luggage, adhesive tape, printing, packaging and other industries.

Series and certifications
Series THE — Temperature Humidity Room. CE certified. Standard 12-month warranty. Custom sizes available. Lifetime remote support.

Overview
Designed for products that do not fit in bench chambers: walk-in access for large parts and machinery with combined temperature and humidity control, adapted to DUT layout and laboratory design. The series features integrated piping and duct design, all-in-one touch control panel and programmable logic controller. Used for reliability testing of complete products in electronics, automotive, LED, PCB and appliances.

Features

• Customization: internal dimensions tailored to the DUT; allows testing without disassembling large equipment.
• Coverage: six low-temperature grades (A–F) down to −70 °C; high-temperature option up to 150 °C.
• Access: walk-in door for full-product testing; supports carts and sliding trays.
• Safety: seven independent protection layers for power, motor, compressor, heater and water supply.

Integrated functions (highlights)

• PID temperature and humidity control for stable, precise regulation across the chamber.
• Programmable profiles: 100 patterns × 999 segments each; supports ramp rate control.
• Humidity sensor for real-time measurement and closed-loop control.
• Independent overheat thermostat.
• 50 mm cable test port to route cables to the DUT.
• USB data storage for exporting test data.
• Heated double-glazed observation window with interior lighting.
• External water supply with convenient refill and auto-recycle.

Standards compatible

• IEC 68-2-1 (Cold)
• IEC 68-2-2 (Dry heat)
• IEC 68-2-3 (Damp heat: steady state)
• IEC 68-2-30 (Damp heat: cyclic)
• IEC 68-2-14 (Temperature change)
• MIL-STD-810G / MIL-STD-810F (Environmental testing)
• ISO 16750-3 (Road vehicles: mechanical loads)

Installation and service
The system is installed and commissioned on site; the supplier plans site layout and utilities, assembles and connects the chamber, calibrates temperature and humidity, and provides operator training. Typical lead time for custom chambers: 30–40 working days from confirmed drawings.

Deliverables

• Installation and operation manual with diagrams and commissioning checklist.
• Export packing list and shipping documents (freight paperwork).
• 12-month warranty (covers chamber, refrigeration system and controller).
• Lifetime remote technical support; on-site commissioning available at additional cost.
