Overview
The LabCompanion PG-225 Programmable Thermal Cycling Chamber is an engineered environmental test system designed for precise, repeatable simulation of extreme temperature conditions across industrial R&D, quality assurance, and reliability validation workflows. Based on forced-air convection with dual-stage refrigeration and PID-controlled electric heating, the chamber delivers stable thermal profiles compliant with core international test standards including IEC 60068-2-1 (cold), IEC 60068-2-2 (dry heat), and MIL-STD-810G Method 502.5. Its robust stainless-steel insulated chamber, high-efficiency compressor cascade refrigeration system, and calibrated platinum RTD sensor array enable reliable operation from -70 °C to +150 °C—making it suitable for accelerated aging, thermal shock pre-conditioning, and component-level qualification testing in electronics, aerospace, automotive, and energy storage applications.
Key Features
- Programmable multi-step thermal profiles with up to 99 segments and 999 cycles per program, supporting ramp-hold-soak sequences with user-defined rates and dwell times
- Dual-stage cascade refrigeration system with environmentally compliant R404A/R23 mixed refrigerant for stable sub-zero performance down to -70 °C
- High-precision PID temperature control using triple-point-calibrated PT100 sensors (Class A tolerance) with real-time deviation compensation
- Double-wall construction with 100 mm thick polyurethane insulation (thermal conductivity ≤0.022 W/m·K) and seamless inner chamber welding for long-term vacuum integrity and condensation resistance
- Front-access large-view observation window with double-layer low-emissivity tempered glass and built-in anti-fog heater
- Standard RS485 interface with Modbus RTU protocol; optional Ethernet (TCP/IP) and USB data logging for integration into centralized lab management systems
Sample Compatibility & Compliance
The PG-225 accommodates samples up to 600 mm × 600 mm × 625 mm (W×H×D) with a maximum payload of 50 kg. Its interior chamber features removable stainless-steel shelves (304 grade), adjustable shelf spacing, and 4× φ50 mm cable/port access ports with silicone grommets. The unit complies with ISO 9001:2015 (design and manufacturing), ISO 14001:2015 (environmental management), and ISO 45001:2018 (occupational health and safety). It supports GLP/GMP-aligned validation protocols—including IQ/OQ/PQ documentation templates—and meets electrical safety requirements per IEC 61010-1. Optional calibration certificates traceable to NIM (China National Institute of Metrology) are available upon request.
Software & Data Management
The chamber operates via the LabCompanion TC-Studio v3.2 control software, compatible with Windows 10/11. The interface supports real-time graphing of up to four channels (chamber setpoint, actual temperature, ramp rate, and external thermocouple input), automatic data export to CSV or Excel, and password-protected user roles (Operator, Engineer, Administrator). Audit trail functionality logs all parameter changes, program starts/stops, and alarm events with timestamps and operator IDs—meeting FDA 21 CFR Part 11 requirements when configured with electronic signature modules. Remote monitoring and alarm notification (email/SMS) are enabled via optional IoT gateway add-on.
Applications
- Thermal cycling validation of PCBAs, battery cells, and power modules per AEC-Q200 and JEDEC JESD22-A104
- Pre-conditioning of optical components and sensors prior to vibration or humidity exposure
- Material coefficient of thermal expansion (CTE) characterization through controlled dimensional drift analysis
- Stability testing of pharmaceutical packaging under ICH Q1A(R2) temperature stress conditions
- Environmental screening of avionics hardware per DO-160 Section 4 (Temperature Variation)
- Long-term reliability assessment of EV traction inverters and SiC MOSFETs under repeated thermal load
FAQ
What is the standard warranty coverage for the PG-225?
LabCompanion provides a 24-month limited warranty covering parts and labor for defects in materials and workmanship, excluding consumables and damage from misuse or unauthorized modification.
Can the PG-225 be integrated into a facility-wide environmental monitoring network?
Yes—the unit supports Modbus RTU over RS485 as standard, and optional Ethernet communication enables direct integration with SCADA, LabVantage, or TrackWise LIMS platforms via OPC UA or custom API.
Is third-party calibration support available?
Certified calibration services traceable to national metrology institutes (NIM, NPL, or NIST) can be arranged through authorized LabCompanion service partners in Shanghai, Chengdu, Xi’an, and Hong Kong.
Does the chamber meet UL or CE safety certification requirements?
The PG-225 carries CE marking per EU Machinery Directive 2006/42/EC and EMC Directive 2014/30/EU; UL listing is available upon request for North American deployments with minor configuration adjustments.
What maintenance intervals are recommended for optimal performance?
Compressor oil and refrigerant levels should be verified annually; air filter cleaning is required every 3 months; full preventive maintenance—including sensor recalibration and refrigeration system leak check—is recommended every 24 months by certified LabCompanion field engineers.
