TF-360B Walk-in Environmental Test Chamber

Overview

The TF-360B Walk-in Environmental Test Chamber is an industrial-grade, fully enclosed climatic simulation system engineered for long-duration, high-fidelity environmental stress testing of large-scale or multi-unit specimens. Designed in accordance with the fundamental principles of psychrometric control and forced-convection thermal management, it delivers precise, stable, and repeatable temperature and humidity profiles across its full operational range of −70 °C to +100 °C and 20–98% RH. Its walk-in architecture supports simultaneous conditioning of aerospace subassemblies, server racks, automotive ECUs, medical device enclosures, and batched electronic components—enabling accelerated life testing, HALT/HASS pre-screening, and compliance validation per IEC 60068-2, MIL-STD-810H, and GB/T 2423 series standards.

Key Features

• Robust structural integrity: 150 mm thick high-density polyurethane insulation with seamless joints minimizes thermal bridging and ensures low heat leakage (<0.8 W/m²·K).
• Precision climate control: Dual independent PID loops govern refrigeration (Tecumseh hermetic compressor with cascade staging for sub-zero operation) and humidification (surface evaporation with stainless-steel water pan and auto-refill), enabling ±0.3 °C temperature and ±2% RH control accuracy under steady-state conditions.
• Uniform environmental distribution: A multi-wing centrifugal circulation system, integrated with aerodynamically optimized ductwork and adjustable directional nozzles, achieves ≤±2.0 °C temperature and ≤±5% RH uniformity throughout the 15 m³ test volume (2.5 × 3.0 × 2.0 m).
• Fail-safe operational safety: Comprehensive protection suite includes compressor high-pressure cut-off, phase sequence monitoring, overcurrent relays for all motor loads, low-water level interlock for humidifier, and redundant over-temperature sensors with independent alarm circuitry.
• Human-centric access & visibility: Triple-pane low-emissivity heated observation window prevents condensation and frosting; standard Ø50 mm test port (customizable) enables real-time signal routing without chamber breach.

Sample Compatibility & Compliance

The TF-360B accommodates physically heterogeneous test articles—including full-size avionics cabinets, battery modules, HVAC control units, and stacked PCB assemblies—without requiring disassembly or spatial compromise. Its interior lined with electropolished SUS#304 stainless steel resists corrosion from saline fog, condensate, and organic vapors. The chamber meets mechanical and electrical safety requirements per IEC 61000-6-2/6-4, complies with CE marking directives (2014/30/EU EMC, 2014/35/EU LVD), and supports GLP/GMP-aligned validation protocols including IQ/OQ/PQ documentation templates. Optional traceable calibration certificates (NIST-traceable RTDs and capacitive RH sensors) are available upon request.

Software & Data Management

Equipped with a 10.1-inch industrial touchscreen HMI running embedded Linux, the system provides intuitive local control with up to 100 programmable test profiles (each supporting ramp-soak cycles, step transitions, and humidity coupling modes). Real-time data logging at 1-second intervals is stored internally (≥30 days) and exportable via USB or Ethernet (Modbus TCP). For regulated environments, optional software add-ons support FDA 21 CFR Part 11 compliance—including electronic signatures, audit trails, role-based access control, and encrypted data archiving—facilitating audit readiness in pharmaceutical, medical device, and defense subcontracting workflows.

Applications

• Aerospace: Thermal cycling of flight control actuators and radar housings per DO-160G Section 4 and 5.
• Automotive: Environmental validation of ADAS domain controllers under combined thermal-humidity stress (ISO 16750-4).
• Energy Storage: Life-cycle preconditioning of Li-ion battery packs prior to electrochemical testing (UN 38.3 T.52).
• Industrial IoT: Burn-in testing of edge computing gateways exposed to tropical or arctic climatic extremes.
• Academic Research: Controlled degradation studies of polymer composites and conformal coatings under cyclic hygrothermal loading.

FAQ

What is the maximum allowable load weight inside the chamber?

The floor structure supports uniformly distributed static loads up to 1,200 kg; point loads must not exceed 300 kg per 0.1 m² contact area.
Can the chamber be integrated into a central facility monitoring system?

Yes—standard Modbus TCP and optional BACnet/IP interfaces enable integration with building management systems (BMS) or SCADA platforms.
Is remote diagnostics supported?

Field-service engineers can initiate secure remote sessions via embedded VPN client for firmware updates, parameter verification, and fault log analysis.
What validation documentation is included?

Factory acceptance test (FAT) report, as-built drawings, electrical schematics, and calibration records for primary sensors are supplied with shipment.
Are custom interior configurations available?

Yes—options include reinforced shelving, cable management trays, internal power distribution panels (220 V / 380 V), and non-reflective matte black interior coating for optical testing.
