Precision Climate Control for Museums and Laboratories
Protect priceless assets and sensitive experiments with exceptionally precise climate control tolerances.
Liebert PDX Constant
Ultra-Precision Climate Control System
Uncompromising environmental stability for critical laboratory processes and priceless archives, with temperature tolerances of ±0.3°C and humidity tolerances of ±2% RH.
Liebert PDX Constant goes beyond conventional climate control systems. It is specifically designed for environments where temperature and humidity must remain virtually unchanged. Equipped with R410A refrigerant and EC Fan 2.0 technology, the system provides not only outstanding protection but also superior energy efficiency.
Ultra-Precise Control
EC fans, modulating compressors, Digital Scroll technology and EconoPhase free cooling modes deliver precise capacity control and improved energy efficiency.
Maximum Efficiency
Air-cooled, water-cooled and multiple free cooling configurations provide complete compatibility with a wide range of operating environments and installation requirements.
24/7 Continuous Reliability
Ideal for environments with fluctuating loads. The iCOM control system modulates capacity according to demand, increasing efficiency while maintaining stable operating conditions.
WHO IS IT IDEAL FOR?
Outstanding Environmental Stability for Critical Applications
Liebert PDX Constant is designed for environments that demand the highest level of temperature and humidity precision.
Operating within exceptionally tight tolerances of ±0.3°C and ±2% RH, the system protects priceless assets and critical processes around the clock, regardless of changing outdoor conditions.
Ideal Application Areas
Liebert PDX Constant: Ultra-Precise Control and Advanced Protection Architecture

Precision Modulation Technology
A specially designed hot gas coil and modulation valve allow the system to adjust its cooling capacity with exceptional precision.
By maintaining stable humidity levels, this technology helps prevent deformation, deterioration and damage to historical documents, sensitive instruments and valuable materials.
Vertiv iCOM Control System
The integrated iCOM control system ensures complete coordination between the indoor unit and the outdoor condenser.
It processes system status and alarm data in real time, maximising operational flexibility, visibility and control.
Optimised Acoustics and Space Utilisation
EC Fan 2.0 technology minimises noise levels while improving unit efficiency.
Its compact design reduces technical space requirements, making it particularly suitable for museums, laboratories and other space-sensitive environments.
24/7 Operational Assurance for Your Critical Assets
24/7 Remote Monitoring and Proactive Diagnostics
Proactive monitoring solutions continuously track critical infrastructure parameters, helping identify potential faults before they develop and maintaining system stability.
