Walk-in Test Chamber

Walk-in Test Chamber

Walk-in Test Chamber Large capacity for bulk and oversized items. Customisable temperature and humidity ranges. Ideal for Automotive components.

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.

Key Specifications

  • Large capacity for bulk and oversized items
  • Customisable temperature and humidity ranges
  • High-performance PUF insulated panel construction
  • Advanced PLC based control with data logging
  • Walk-in accessibility with heavy-duty floor

Key Features

  • Modular Cam-Lock PUF Construction: Tongue-and-groove panels with thermal-bridge-free assembly — on-site build-up in 2–5 days, no permanent installation required
  • Heavy-Duty Floor Reinforcement: Stainless steel 304 checkered plates support full vehicles (up to 3,000 kg/m²) and EV battery packs without floor deflection
  • 100+ Air Exchanges per Hour: Turbo-blower with mist elimination maintains ±1°C uniformity across chambers up to 100+ m³ — prevents stratification in large volumes
  • Advanced Humidity Control: 10–95% RH standard (5–98% RH in performance models) with dew-point sensing and dual-compressor design for rapid ramp cycles
  • Fast-Ramp Option: Up to 5°C/min thermal transitions — welded high-temp steel construction for ALT and thermal shock protocols
  • Personnel Safety System: Interior door release mechanism, emergency audible alarm, and main kill switch — disables all heating/cooling for immediate safe exit
  • Temperature Range: Standard S-Series -40°C to +85°C; Drive-In L-Series -20°C to +85°C; Fast-Ramp -70°C to +150°C
  • Optional: Multi-zone sensor arrays, cloud data logging with real-time alerts, IoT compliance reporting

Applications

  • Automotive Components & Full Vehicle Testing: Door seals, HVAC, ECMs, infotainment systems, and full vehicle validation per OEM protocols
  • EV Battery Testing: BMS qualification, high-voltage harness testing, module-level thermal cycling for cell safety validation
  • Aerospace Large Assemblies: Flight control surfaces, avionics racks, and structural panels under combined thermal and humidity stress
  • Electronics & Power Distribution: Industrial inverters, power supplies, and converter reliability under combined temperature and humidity stress
  • Contract Testing Laboratories: 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 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 and bias assessment
  • MIL-STD-810H — DoD Environmental Engineering Test Method Standard
  • ISO 17025 / NABL — Chamber uniformity mapping, temperature/humidity calibration, and traceability documentation

Safety Features

  • Independent over-temperature safety limit with alarm
  • Pressure relief ports for rapid temperature transitions
  • Personnel safe-release hardware and emergency alarms
  • Electrical safety circuit with phase and motor protection

Optional Features

  • Inert gas purging and oxygen concentration monitoring
  • Multi-channel data logging and remote SCADA access
  • Customised cable ports and passthroughs for test items
  • Heavy-duty reinforced floor for vehicle or pallet loading

How It Works

  1. Load test items into the chamber using a trolley or pallet jack
  2. Configure the environmental test profile on the PLC touchscreen
  3. The system regulates cooling, heating, and moisture according to the setpoints
  4. Integrated airflow systems ensure uniform conditions across the entire room
  5. Monitor and record data for the duration of the environmental cycle

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.
