Memmert HPPeco Temperature and Humidity Controlled Chamber

Overview

The Memmert HPPeco is a precision-engineered upright temperature and humidity controlled chamber designed for long-term stability testing, accelerated aging studies, and environmental stress screening in pharmaceutical, biotechnology, materials science, and quality assurance laboratories. Operating on a dual-climate control principle—combining Peltier-based cooling with electric heating and steam humidification—the HPPeco achieves high reproducibility in maintaining setpoint conditions across its full operating range (0–70 °C; 10–90 % RH). Its thermally insulated stainless-steel chamber, integrated air circulation system with laminar flow design, and PID-controlled microprocessor ensure minimal spatial deviation (<±0.3 K temperature uniformity, <±2 % RH homogeneity per IEC 60068-3-5) over time. Unlike conventional chambers relying solely on resistive heating and passive humidification, the HPPeco employs active dew point control and adaptive vapor pressure regulation to deliver consistent moisture delivery under varying thermal loads—critical for ISO 14644-1 cleanroom-compatible storage protocols and ICH Q1A(R2) stability testing requirements.

Key Features

• Reinforced stainless-steel chamber construction with double-walled insulation and seamless welded corners for enhanced thermal integrity and corrosion resistance
• Two standard reinforced adjustable shelves—available in grid or perforated configuration—to support uniform airflow and flexible sample loading
• Dual-color white LED lighting system with selectable correlated color temperature (CCT) between 3000 K (warm white) and 6500 K (cool white), enabling photostability assessment per ICH Q5C guidelines
• Intelligent climate control algorithm with real-time compensation for door openings, load mass changes, and ambient fluctuations
• Touchscreen interface with multilingual support (English, German, French, Spanish), password-protected user levels, and configurable alarm thresholds
• Integrated Ethernet port and optional RS485/Modbus RTU connectivity for centralized monitoring and integration into LIMS or SCADA systems

Sample Compatibility & Compliance

The HPPeco accommodates a wide range of sample formats—including vials, trays, petri dishes, blister packs, polymer films, and electronic components—without compromising environmental fidelity. Its chamber volume options (110, 260, 410, 750, 1060, 1400, and 2200 L) allow scalability from benchtop validation studies to full-scale stability chambers. The system complies with key international standards including DIN EN 60068-2 (environmental testing), ISO 14644-1 Class 5–8 air cleanliness (when equipped with HEPA filtration option), and EU GMP Annex 15 for qualification of environmental test equipment. All firmware versions support 21 CFR Part 11-compliant audit trails, electronic signatures, and data integrity safeguards when paired with Memmert’s optional software suite.

Software & Data Management

The HPPeco is compatible with Memmert’s validated software platform, *memmert connect*, which enables remote supervision, automated report generation (PDF/CSV), and trend analysis of temperature/humidity profiles over extended durations. Data logging occurs at user-defined intervals (1 s to 24 h resolution), with internal memory retaining up to 10 years of continuous records (depending on sampling rate). The software supports ALCOA+ principles—ensuring data is Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, and Available—for regulatory submissions to FDA, EMA, and PMDA. Optional cloud synchronization provides secure offsite backup and multi-site comparative analytics.

Applications

• ICH Q1A(R2)-compliant long-term and accelerated stability testing of drug substances and products
• Accelerated degradation studies for polymers, adhesives, and packaging materials per ASTM D3574 and ISO 11357
• Environmental stress screening of printed circuit boards (PCBs) and medical devices per IPC-9701 and ISO 14971
• Seed germination and plant tissue culture under controlled photoperiodic and hygrothermal conditions
• Calibration and verification of reference hygrometers and thermometers per ISO/IEC 17025
• Storage of reference standards, biological reagents, and diagnostic kits requiring defined温湿度 envelopes

FAQ

What is the temperature uniformity specification across the working volume?
Temperature uniformity is ≤ ±0.3 K at 20 °C and 60 % RH, measured at nine points per IEC 60068-3-5.
Can the HPPeco be qualified according to GxP requirements?
Yes—the system supports IQ/OQ/PQ documentation packages, and all firmware revisions are validated for use in GLP/GMP environments with full traceability.
Is steam humidification suitable for low-humidity operation?
The HPPeco uses a combination of steam injection and desiccant-assisted dehumidification to achieve stable control down to 10 % RH without condensation risk.
Does the chamber support external sensor inputs for custom monitoring?
Optional analog input modules (0–10 V / 4–20 mA) allow integration of third-party probes for CO₂, O₂, or VOC monitoring.
What is the expected service life of the Peltier cooling module?
Rated for >50,000 hours of continuous operation under nominal load, with field-replaceable modular design minimizing downtime.
