LabCompanion HLT/HA36 Advanced Temperature and Humidity Cycling Chamber

Overview

The LabCompanion HLT/HA36 is an engineered environmental test chamber designed for precise, repeatable temperature and humidity cycling in compliance with international reliability testing standards. Based on the principle of forced-air convection combined with dual-stage cascade refrigeration and surface-evaporative or pressure-jet humidification, this chamber delivers tightly controlled thermal and hygrothermal stress profiles essential for evaluating product robustness under accelerated aging, qualification, and validation protocols. Its architecture supports both steady-state conditioning and dynamic ramp-soak cycling—enabling simulation of real-world operational extremes encountered in aerospace electronics, automotive ECUs, medical device packaging, and pharmaceutical stability studies. The unit operates within a certified temperature range of −20 °C to +125 °C (with optional −40 °C or −70 °C low-temperature configurations) and maintains humidity between 25 %RH and 98 %RH, making it suitable for IEC 60068-2-1 (cold), -2 (dry heat), -14 (change of temperature), and -30 (damp heat cyclic) test methods.

Key Features

• Compact footprint with integrated casters for lab-floor mobility—ideal for shared testing facilities or cross-departmental deployment.
• Intuitive front-panel interface with imported digital temperature/humidity controller; optional IPC500 LCD touchscreen for multi-step program editing and real-time parameter visualization.
• Energy-optimized control logic that autonomously detects internal thermal load and modulates compressor staging and heater duty cycle—reducing power consumption and acoustic emissions during low-load operation.
• Air-cooled cascade refrigeration system using environmentally compliant dual-refrigerant circuits (R404A/R23), enabling rapid cooling from ambient to −40 °C in under 15 minutes without external water supply.
• Stainless steel inner chamber (AISI 304) with seamless welds and electropolished finish ensures corrosion resistance, ease of cleaning, and long-term dimensional stability—critical for GLP-compliant environments.
• Dual independent safety layers: hardware-based over-temperature cutoff (separate from main controller) plus comprehensive electrical protection (leakage current, phase loss, overload, and water-level monitoring for humidifier).

Sample Compatibility & Compliance

The HLT/HA36 accommodates samples up to 400 mm (W) × 300 mm (D) × 300 mm (H), with uniform airflow distribution validated per IEC 60068-3-5. Its construction meets mechanical and electromagnetic requirements for Class II laboratory equipment per IEC 61000-6-2/6-3. All thermal and humidity performance specifications are verified traceably to national metrological standards (GB/T 2423.1–4, GB 10586–89, GB 10592–89), and the chamber is routinely deployed in ISO/IEC 17025-accredited labs for test method validation. For regulated industries, the optional IPC500 controller supports audit-ready data logging with time-stamped events, user access levels, and exportable CSV reports—aligning with FDA 21 CFR Part 11 principles for electronic records and signatures when paired with secure network configuration.

Software & Data Management

While the base model operates via standalone controller firmware, the IPC500 upgrade enables PC-based remote supervision through Ethernet or RS485. The embedded software allows creation of up to 100 programmable cycles (each with 99 segments), including ramp rates (0.1–10 °C/min configurable), dwell times, and humidity transitions. All logged data—including chamber setpoints, actual values, alarm timestamps, and system status—are stored internally for ≥30 days and exportable via USB or network transfer. Raw data files comply with ASTM E2911-13 formatting conventions, facilitating integration into LIMS or quality management systems (QMS) such as TrackWise or MasterControl. No proprietary drivers or cloud dependencies are required—ensuring full data sovereignty and long-term archival integrity.

Applications

• Electronics: Thermal cycling of PCBAs per JEDEC JESD22-A104, solder joint fatigue analysis, and moisture sensitivity level (MSL) preconditioning.
• Aerospace: Environmental stress screening (ESS) of avionics per MIL-STD-810H Method 502.7 (low temperature), 503.5 (temperature shock), and 507.6 (humidity).
• Automotive: Component validation against ISO 16750-4 (climate loads) and GMW3172 (thermal durability).
• Pharmaceuticals: Accelerated stability testing per ICH Q1A(R3) and packaging permeability assessment under controlled RH gradients.
• Materials Science: Polymer aging studies, adhesive bond strength degradation, and composite delamination kinetics under combined thermal-hygrometric stress.

FAQ

What is the standard calibration interval recommended for the HLT/HA36?
LabCompanion recommends annual verification of temperature and humidity sensors against NIST-traceable references, with additional spot checks before critical qualification runs per ISO/IEC 17025 Clause 6.5.

Can the chamber be integrated into an existing factory MES or SCADA system?
Yes—the IPC500 controller supports Modbus TCP and OPC UA protocols for bidirectional communication with industrial automation platforms without middleware.

Is dehumidification capability included, or is it humidity-only?
The unit provides active dehumidification via refrigerated coil condensation and optional desiccant assist, enabling stable operation down to 25 %RH across the full temperature range.

Are validation documents (IQ/OQ/PQ protocols) provided with purchase?
Standard delivery includes a Factory Acceptance Test (FAT) report. Custom IQ/OQ documentation packages are available upon request and align with Annex 15 and GAMP 5 guidelines.

What maintenance is required to sustain specified performance over time?
Quarterly inspection of condenser coils, humidifier tank cleanliness, and door gasket integrity is advised. Refrigerant charge verification and sensor recalibration are performed annually during scheduled service.
