Aralab FitoClima Walk-in Environmental Test Chamber

Overview

The Aralab FitoClima Walk-in Environmental Test Chamber is an engineered solution for long-term, high-fidelity environmental simulation in pharmaceutical, biotechnology, materials science, and academic research laboratories. Built upon ARALAB’s decades of expertise in precision climate control since 1985, this chamber operates on a robust thermodynamic architecture combining forced-air convection, dual-stage refrigeration, and PID-regulated heating to deliver tightly controlled, spatially uniform conditions across large-volume test spaces. Its design adheres to the physical principles of convective heat and mass transfer, enabling reproducible simulation of real-world environmental stressors—including accelerated aging, photostability, and cyclic thermal/hygrometric profiles—essential for regulatory stability studies under ICH guidelines and material degradation analysis.

Key Features

• Full-color touchscreen controller with intuitive navigation, real-time parameter visualization, and programmable multi-step profiles (up to 99 segments per program)
• High-precision temperature control range from –60°C to +85°C and humidity range from 10% to 95% RH (non-condensing), validated at measurement points located 5 cm from walls, floor, and ceiling
• Thermal and hygric uniformity verified per ISO 14644-3 and ASTM E2875: temperature uniformity ≤ ±1.0°C; humidity uniformity ≤ ±2.0% RH
• Hermetically sealed, fluorocarbon-free refrigeration system with water-cooled condenser (standard for sub-zero operation); optional air-cooled configuration available for ambient-temperature installations
• Dual independent variable-frequency fans (top and rear-mounted) ensure laminar airflow distribution and minimize thermal stratification
• AISI 304 stainless steel interior with full seam welding prevents corrosion, facilitates cleaning, and supports ISO Class 5 cleanroom-compatible operation
• Integrated safety architecture includes redundant temperature/humidity sensors, independent alarm circuits, automatic shutdown on deviation exceedance, and fault-locked restart protocol
• Cold-frame door with electrically actuated emergency release and anti-condensation heating eliminates frost formation and ensures seal integrity during low-temperature operation

Sample Compatibility & Compliance

The FitoClima chamber accommodates heterogeneous sample loads—including stacked stability shelves, open trays, sealed containers, and instrumented sensor arrays—without compromising environmental fidelity. Its internal volume (configurable across multiple standard footprints) allows simultaneous conditioning of multiple ICH-defined storage conditions (e.g., 25°C/60% RH, 30°C/65% RH, 40°C/75% RH) within a single unit. The system complies with critical regulatory frameworks: it supports data integrity requirements per FDA 21 CFR Part 11 when integrated with compliant software platforms; meets structural and performance criteria outlined in ICH Q1A(R2), Q5C, and Q5D; and is routinely deployed in GLP- and GMP-audited facilities for stability-indicating method development and shelf-life determination.

Software & Data Management

While the onboard controller provides local logging (up to 10,000 data points), the FitoClima supports RS232 serial communication for integration with third-party laboratory information management systems (LIMS) or centralized monitoring platforms. Optional Ethernet-enabled modules enable remote access, alarm forwarding via email/SMS, and audit-trail generation aligned with ALCOA+ principles. All recorded parameters—including setpoints, actual values, alarm events, and operational status—are time-stamped with traceable UTC synchronization. Raw data export is supported in CSV format for statistical process control (SPC) analysis and trend reporting required by quality assurance departments.

Applications

• ICH-compliant drug substance and product stability testing (long-term, intermediate, and accelerated conditions)
• Photostability assessment when coupled with optional UV/visible light modules (IEC 60068-2-5 compliant)
• Material aging studies for polymers, composites, coatings, and electronic components
• Seed germination, plant growth, and phytopathological research requiring precise diurnal cycling
• Calibration and validation of secondary environmental sensors and portable data loggers
• Pre-conditioning of test specimens prior to mechanical, electrical, or chemical characterization

FAQ

What is the standard cooling configuration for operation below 0°C?
The FitoClima chamber is supplied with a water-cooled condenser as standard for sub-zero applications. Air-cooled alternatives are available upon request for installations where chilled water infrastructure is unavailable.
Can the chamber be validated per IQ/OQ/PQ protocols?
Yes—ARALAB provides Factory Acceptance Test (FAT) documentation, and the chamber is designed to support user-executed Installation Qualification (IQ), Operational Qualification (OQ), and Performance Qualification (PQ) using calibrated reference sensors and NIST-traceable standards.
Is remote monitoring and alarm notification supported?
Remote monitoring is enabled via optional Ethernet connectivity. Alarm notifications—including temperature/humidity excursions, power failure, and door-open events—can be configured for email or SMS delivery through compatible middleware.
What materials are used in the chamber’s construction to ensure chemical resistance and cleanability?
The interior is fabricated from fully welded AISI 304 stainless steel. The exterior features epoxy-coated galvanized steel (RAL 7035), offering durability against laboratory-grade cleaning agents and routine disinfection protocols.
Does the system meet noise emission limits for placement in shared laboratory spaces?
Acoustic output is ≤ 62 dB(A) at 1 m distance under normal operating conditions, meeting ISO 7779 and EU Directive 2000/14/EC requirements for laboratory equipment in non-industrial settings.
