Walk-in Chamber

Walk-in Chamber

Modular walk-in test chamber 2–100 m³, −40°C to +120°C, 10–95% RH. For large product environmental testing and EV battery validation. 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.

  • Advanced Humidity Control: 10–95% RH (5–98% in performance models) with dew-point sensing and dual-compressor design for rapid ramp cycles.
  • Personnel Safety: Interior door release mechanism + emergency audible alarm + main kill switch—disables all heating/cooling for immediate safe exit.
  • Integrated Data Logging: Optional multi-zone sensor arrays (temperature, humidity, pressure) with cloud integration for compliance documentation.
  • ⚡ 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.
  • Electronics & Power Distribution: Industrial power supplies, inverters, and converter reliability under combined thermal + humidity stress.
  • Contract Testing Labs: High-throughput multi-client capability with certified uniformity, SPC data logging, and audit trail documentation.
  • R&D Prototype Durability: Accelerated life testing (ALT) and failure mode analysis for new automotive and aerospace components.

Compliance Standards

  • SAE J2030: Environmental Limits and Testing Requirements for Electronic Equipment in Heavy-Duty Vehicles
  • ASTM E691: Round-Robin Testing for Environmental Chambers (Precision & Bias Assessment)
  • MIL-STD-810H: Department of Defense Test Method Standard for Environmental Engineering Considerations
  • ISO 17025: Accreditation Standard for Calibration Services (Chamber Uniformity Mapping)
  • NABL Accreditation: Temperature, Humidity, and Ramp-Rate Validation

Safety Features

  • Over-temperature and under-temperature protection
  • Emergency stop and safety interlocks (door and system)
  • Compressor and overload protections for refrigeration system

Optional Features

  • Multiple access doors and observation window options
  • Data logging, report export and validation support

How It Works

  1. Load test samples or assemblies into the walk-in chamber
  2. Set temperature and humidity profile on the controller
  3. Chamber conditions stabilise and maintain setpoints
  4. Run test cycles for qualification and reliability validation
  5. Record data for compliance, reporting and traceability

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.
