The Lunaire CE205 is an environmental control component designed for integration into Lunaire test chambers to manage and regulate temperature and humidity with precision. It maintains consistent environmental conditions across the chamber volume through coordinated control of heating, cooling, and humidification systems—essential for stability testing, shelf-life validation, accelerated aging studies, and equipment qualification per ICH guidelines.
Technical Specifications
Control Architecture
• Watlow 96 controller with RTD sensors for temperature measurement
• Capacitive sensors for humidity measurement
• Digital-set, digital-readout control interface
• Display resolution: 0.1°C or 0.1°F
Temperature Control
• Regulation via sealed stainless steel alloy tubular heating elements
• Single-stage refrigeration system with hermetically sealed reciprocating compressor and non-CFC refrigerant (when cooling is specified)
• Temperature uniformity: ± 0.5°C across chamber
• Low-limit and high-limit shutdown circuits for over-temperature protection
Humidity Control
• Measurement range: 20% to 96% RH (standard); above ambient to 96% RH (optional)
• Optional auxiliary dryer systems for lower humidity ranges
