LabCompanion RP-80U Temperature and Humidity Controlled Chamber

Overview

The LabCompanion RP-80U is a precision-engineered temperature and humidity controlled chamber designed for rigorous environmental simulation in R&D laboratories, quality assurance departments, and materials testing facilities. It operates on the principle of Balanced Temperature and Humidity Control (BTHC), integrating independent yet coordinated refrigeration, heating, humidification, and air circulation subsystems to maintain stable, repeatable climatic conditions across its full operational envelope. The chamber supports dynamic programmable profiles per IEC 60068-3-6 and ASTM D4332 standards, enabling accelerated aging, stability testing, and preconditioning of electronic components, polymers, pharmaceutical packaging, and aerospace composites. Its core architecture prioritizes thermal inertia minimization and humidity response fidelity—critical for validating product behavior under real-world storage or operational environments.

Key Features

• Energy-optimized design delivering up to 30% lower power consumption and 20% reduced water usage versus conventional chambers, compliant with ISO 50001 energy management principles.
• Hermetically sealed French Tecumseh compressor system using non-ozone-depleting HFC refrigerant (R-404A or R-134a variant), certified per EU F-Gas Regulation (EU No 517/2014) and EPA SNAP program requirements.
• SUS304 stainless steel interior and exterior construction with electropolished finish and seamless arc-welded corners—resistant to corrosion from saline mist, acidic vapors, and repeated condensation cycles.
• Dual-stage safety architecture: real-time monitoring of chamber temperature, humidity, refrigerant pressure, and heater current, triggering automatic shutdown and audible/visual alarm within <100 ms upon deviation exceeding preset thresholds.
• Integrated USB data logger supporting continuous timestamped recording of temperature, humidity, setpoint, and alarm events at user-selectable intervals (1 s to 60 min); data export compatible with CSV and Excel formats for GLP/GMP audit trails.
• RS-232/RS-485 communication interface conforming to Modbus RTU protocol, enabling centralized supervision of up to 200 units via SCADA or LIMS platforms—ideal for multi-chamber validation studies requiring synchronized environmental exposure.
• Optimized airflow system featuring centrifugal blower with adjustable vane geometry and rear-mounted heating/humidifying elements, ensuring ≤±2.0°C temperature uniformity and ≤±2.5% RH uniformity across the entire 400×500×400 mm working volume (per ISO 16750-4 Annex C).

Sample Compatibility & Compliance

The RP-80U accommodates test specimens up to 30 kg with unrestricted access via dual-latching door and ergonomic front-loading water reservoir (18 L capacity). Its wide operating range (–60°C to +150°C; 10–98% RH) meets critical requirements for MIL-STD-810H Method 502.7 (low temperature), Method 507.6 (humidity), and ICH Q1A(R2) stability testing guidelines. Optional upgrades—including chemical desiccant dehumidification (≤5% RH), pure water distillation unit (ASTM D1193 Type II), and calibrated temperature/humidity recorders traceable to NIST—support FDA 21 CFR Part 11 compliance when paired with validated software configurations. All electrical components comply with IEC 61000-6-3 (EMC) and IEC 61000-6-2 (immunity) standards.

Software & Data Management

The embedded controller runs a deterministic real-time OS with password-protected user levels (Operator, Engineer, Administrator). Profile programming supports up to 100 segments with ramp/soak logic, conditional branching, and event-triggered outputs (e.g., relay activation upon humidity threshold breach). Data logging includes automatic checksum verification, cyclic buffer overwrite protection, and tamper-evident file naming (YYYYMMDD_HHMMSS_RP80U_001.csv). Raw logs are exportable without proprietary software dependency—facilitating third-party statistical process control (SPC) analysis or integration into enterprise MES systems. Audit trail functionality records all parameter changes, login/logout events, and calibration actions with user ID and timestamp—fully aligned with ALCOA+ data integrity principles.

Applications

• Accelerated life testing of lithium-ion battery cells under thermal-hygric stress (UN 38.3 Thermal Cycling Test).
• Stability assessment of sterile medical device packaging per ISO 11607-1:2019 accelerated aging protocols.
• Validation of adhesive bond strength retention in automotive trim components exposed to tropical climate profiles (ISO 16750-4).
• Preconditioning of optical lenses and sensor housings prior to spectral transmittance measurement (ASTM E308).
• Environmental stress screening (ESS) of PCB assemblies per JEDEC JESD22-A108F.

FAQ

What is the standard calibration certificate included with the RP-80U?
A factory-issued as-found/as-left calibration report is provided, covering three-point temperature (–40°C, 25°C, +85°C) and three-point humidity (30%, 60%, 90% RH) verification using NIST-traceable reference sensors.
Can the RP-80U be integrated into an existing building management system (BMS)?
Yes—via optional BACnet/IP or Modbus TCP gateway module (sold separately), enabling read-only monitoring of chamber status, setpoints, and alarms through standard BMS dashboards.
Is remote firmware update supported over the network interface?
Firmware updates require local USB media upload only; no internet-connected update mechanism is implemented to preserve cybersecurity integrity per IEC 62443-3-3 SL2 requirements.
What maintenance intervals are recommended for the refrigeration system?
Compressor oil and filter replacement every 24 months under continuous operation; annual inspection of refrigerant charge and condenser coil cleanliness is advised.
Does the chamber meet IP ratings for dust or water ingress protection?
No—this is a laboratory-grade environmental chamber, not an enclosure rated per IEC 60529; external dust/water protection must be provided by facility-level engineering controls.
