MEMMERT STABILITY-FITOCLIMA 20000 Walk-in Environmental Test Chamber

Overview

The MEMMERT STABILITY-FITOCLIMA 20000 is a high-precision walk-in environmental test chamber engineered for long-term stability testing under strictly controlled temperature and humidity conditions. Designed in accordance with the fundamental principles of thermodynamic equilibrium and psychrometric control, it employs dual-channel PID-controlled refrigeration and steam-based humidification systems to maintain stable setpoints across large-volume chambers. Its robust stainless-steel insulated construction, combined with airtight door seals and laminar airflow management, ensures minimal spatial gradient deviation—critical for ICH-compliant storage and accelerated stability studies. Unlike compact benchtop chambers, the STABILITY-FITOCLIMA 20000 delivers uniform environmental distribution across its entire 20,000-liter internal volume, validated per ISO 14644-1 (Class 8 cleanroom-compatible configuration optional) and aligned with the spatial uniformity requirements defined in ICH Q5C and USP . The system operates continuously within a certified temperature range of 15°C to 45°C and relative humidity range of 35% to 90% rH—covering all standard ICH climatic zones (Zone I–IV), including long-term (25°C/60% rH), intermediate (30°C/65% rH), and accelerated (40°C/75% rH) conditions.

Key Features

• High-stability climate control architecture featuring independent refrigeration and steam humidification circuits with real-time feedback compensation
• Pre-installed, height-adjustable stainless-steel shelving system with load-rated supports (up to 50 kg per shelf level), enabling flexible sample layout optimization
• Integrated alarm logic engine supporting configurable high/low temperature and humidity thresholds, with relay outputs for external notification systems (e.g., SMS gateways, SCADA integration)
• Touchscreen HMI with multi-user access control, audit trail logging, and electronic signature capability compliant with FDA 21 CFR Part 11 and GAMP 5 guidelines
• Factory-provided IQ/OQ documentation package; PQ support services available upon request for full GxP validation lifecycle management
• Energy-efficient design incorporating variable-speed compressors and heat recovery loops—reducing operational costs over extended 24/7/365 operation cycles

Sample Compatibility & Compliance

The STABILITY-FITOCLIMA 20000 accommodates diverse sample formats—including sealed vials, blister packs, bulk containers, and palletized cartons—without compromising environmental homogeneity. Its chamber geometry and airflow profile are validated to meet ICH Q1A(R2) requirements for spatial uniformity (±2°C temperature deviation, ±5% rH deviation across working volume). All firmware and software components are developed under a documented quality management system compliant with ISO 13485 and aligned with EU Annex 11 (Computerised Systems). Full traceability is ensured via time-stamped event logs, user action records, and tamper-evident data archiving. Optional qualification packages include installation qualification (IQ), operational qualification (OQ), and performance qualification (PQ) protocols executed per ISO/IEC 17025-accredited procedures.

Software & Data Management

The embedded MEMMERT eCOM software platform provides secure, role-based access to real-time monitoring, historical trend analysis, and automated report generation. Data integrity safeguards include encrypted local storage, redundant backup to network-attached storage (NAS), and optional cloud synchronization with TLS 1.2+ encryption. Audit trails capture every parameter change, user login/logout, alarm activation, and calibration event—fully searchable and exportable in PDF/A or CSV format. Electronic signatures adhere to ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available) and support multi-level approval workflows required for regulatory submissions to EMA, FDA, PMDA, and Health Canada.

Applications

• ICH Q1–Q5 stability studies for pharmaceuticals, biologics, and combination products
• Long-term and accelerated shelf-life determination in food, beverage, and nutraceutical R&D
• Regulatory-compliant storage of reference standards and retained samples under GMP conditions
• Stability assessment of cosmetic formulations, veterinary therapeutics, and medical device packaging
• Environmental stress testing for quality control laboratories performing release testing per USP , Ph. Eur. 2.1.7, and JP 17
• Climate-controlled incubation for non-sterile biological materials requiring consistent low-temperature storage (e.g., 15°C–25°C ambient stability hold)

FAQ

Does the STABILITY-FITOCLIMA 20000 support remote monitoring and alarm notifications?

Yes—it integrates with third-party building management systems (BMS) and supports SNMP, Modbus TCP, and email/SMS alerts via configurable relay outputs and optional gateway modules.
Can the chamber be validated for GMP compliance?

Yes—factory-supplied IQ/OQ documentation is included; PQ execution and protocol customization are available through MEMMERT’s global validation support team.
Is humidity control achievable at temperatures below 20°C?

Yes—the system maintains stable humidity down to 15°C using precision steam injection and condensation management algorithms validated per ISO 12780.
What is the maximum allowable payload weight inside the chamber?

The standard shelving system supports up to 50 kg per shelf level; total payload capacity depends on configuration and must be confirmed during engineering review prior to installation.
Are calibration certificates provided with the system?

NIST-traceable temperature and humidity sensor calibration certificates are supplied at commissioning; annual recalibration services are available under service agreement.
