Climate chamber THR

temperaturehumidityaging

Product summary
A walk-in temperature-humidity climatic chamber (THR Series) designed for accelerated aging and climatic stability tests on large DUTs such as optical fiber drums, electronic assemblies, automotive components and other full-size products. Suitable where benchtop chambers cannot accommodate the sample size or test setup.

Types

• Modular walk-in chambers: foam-insulated panels assembled to form rooms of customizable sizes.
• Welded (solid) walk-in chambers: fully welded construction for higher humidity/temperature resistance and faster thermal change rates.

Specification highlights

• Model: THR Series / THR‑volume — low-temperature grades A–F.
• Internal dimensions: factory-customizable to match DUT and lab layout.
• Temperature range: Low A–F (A: 25 °C; B: 0 °C; C: −20 °C; D: −40 °C; E: −60 °C; F: −70 °C); High standard 80 °C (optionally 80–150 °C).
• Humidity range: 20%–98% R.H. (optional 10–98% or 5–98% with dehumidifier).
• Resolution / uniformity: 0.1 °C; 0.1% R.H. / ±2.5 °C; ±3.5% R.H.
• Control accuracy: ±0.5 °C; ±2.5% R.H.
• Temperature change rates: Rise ~0.1–3.0 °C/min; Fall ~0.3–1.0 °C/min (faster rates optional).
• Cooling: water-cooled or air-cooled; compressor options (Tecumseh, Bitzer).

Overview
The THR Series provides programmable PID temperature and humidity control, PLC and touch-screen HMI, USB data export, heated double-glazed viewing window and a 50 mm cable test port for routed connections. Room dimensions and internal fittings are customized to accommodate assembled products and test fixturing.

Features

• Custom inner dimensions to test full-size DUT without disassembly.
• Six low-temperature grades down to −70 °C; optional high-temperature extension to 150 °C.
• Walk-in access and trolley-compatible thresholds for moving assembled equipment.
• Multi-layer safety protections: power, motor, compressor, heater and water supply monitoring.
• Programmable profiles: up to 100 patterns × 999 segments with ramp-rate control.
• Real-time humidity sensor for closed-loop control and overheat thermostat for independent protection.
• Data logging via USB for test records and reporting.

Standards

• IEC 68-2-1 / IEC 68-2-2 / IEC 68-2-3 / IEC 68-2-30 / IEC 68-2-14
• MIL-STD-810G / MIL-STD-810F
• ISO 16750-3

Safety & protection

• Earthing and leakage protection
