Walk-in Test Chamber
Walk-in environmental test chamber for full-vehicle and large sub-assembly testing. −70°C to +180°C, 20–98% RH, custom floor loading. Get a quote.
A walk-in chamber is an insulated environmental enclosure large enough for personnel and equipment access, enabling real-time testing of full systems—vehicles, powertrains, battery modules—under controlled temperature and humidity. Unlike benchtop chambers, walk-ins offer modular construction for rapid deployment, heavy-duty floors for vehicle loading, and scalable volume from 2 m³ (compact labs) to 100+ m³ (contract testing hubs). Advanced models support thermal ramp rates up to 5°C/min, critical for automotive qualification and aerospace durability validation.

- ⚡ SAE J2030 & MIL-STD-810 Qualified: Our chambers support automotive and military environmental testing standards, including thermal shock (-40 to +85°C), temperature cycling, and humidity life per J2030 and MIL-STD-810H.
- ⚡ Modular Cam-Lock Assembly: Tongue-and-groove PUF panel design eliminates thermal bridges and enables rapid assembly without special tools—ideal for temporary or relocatable testing facilities.
- ⚡ 100+ Air Exchanges/Hour (AHU): Powerful turbo-blower and mist elimination system maintain ±1°C uniformity across entire volume, preventing hot/cold spots and enabling precise component failure analysis.
- ⚡ Vehicle-Grade Floor Reinforcement: Stainless steel 304 checkered plates rated for full-vehicle testing (EVs up to 2,500 kg+ per wheel) without deflection or stress concentration.
- 25+ Years of Large-Scale Chamber Design: Custom volume scaling, high-performance AHU integration, and rapid modular deployment for contract labs.
- NABL/ISO 17025 Accreditation: Full chamber uniformity mapping, temperature/humidity calibration, and traceability documentation included.
- Turnkey EV & Automotive Solutions: Pre-qualified for OEM and Tier-1 supplier testing protocols (Tesla, Ford, BMW, Bosch).
- 24/7 Remote Monitoring: Optional cloud-based sensor data logging with real-time alerts and compliance reporting.
- Extended Spare Parts Inventory: AHU compressors, PUF panels, and control systems stocked for rapid repair and zero downtime.
Applications
- Automotive Components & Full Vehicle Testing: Door locks, HVAC systems, electronic control modules (ECMs), infotainment systems, and complete vehicle validation per OEM protocols.
- EV Battery Testing: Battery management systems (BMS), high-voltage harness qualification, and module-level thermal cycling for cell safety validation.
- Aerospace Large Assemblies: Flight control surfaces, cabin pressurization systems, avionics racks, and structural panel vibration + thermal testing.

Frequently Asked Questions
Q: What is the difference between Standard and Large/Drive-In series?
A: Standard (S-Series, 2–12 m³) accommodates benchtop equipment and small assemblies with personnel access via door. Large (L-Series, 20–100+ m³) features drive-in access and reinforced floor (3,000 kg/m²) for full-vehicle and engine testing.
Q: How accurate is the ±1°C uniformity specification?
A: Uniformity is measured per ASTM E691 across 9–16 sensor points distributed throughout the chamber at mid-cycle. Achieved via 100+ air exchanges/hour and optimized return-air ducting.
Q: Can you retrofit an existing chamber for higher ramp rates?
A: Partial retrofits (improved AHU, control upgrade) are possible but limited by chamber mass and compressor capacity. For 5°C/min ramps, a new welded Fast-Ramp design is recommended.
Q: Do you provide ISO 17025 calibration certificates?
A: Yes. Our NABL-accredited lab offers annual chamber uniformity mapping, control sensor calibration, and traceability documentation as part of the comprehensive service plan.
Q: What is the typical energy consumption for a 50 m³ chamber?
A: 15–25 kW (heating) + 8–12 kW (cooling compressors + AHU) depending on thermal load and ramp rate. We provide detailed power budgets during design phase.
