Cleanroom Temperature & Humidity Controllers
Cleanroom Temperature & Humidity Controllers: Climate Stability for Sensitive Research
In pharmaceutical manufacturing and microbial research, even a slight fluctuation in environmental conditions can jeopardize years of work or compromise product safety. Metrolabs provides high-accuracy Temperature & Humidity (T/H) Controllers, engineered to provide absolute atmospheric stability.
Our controllers are the central nervous system of your Cleanroom AHU, ensuring that your facility operates within the narrow parameters required for ISO and GMP compliance.
Why Climate Control is Non-Negotiable
Beyond personnel comfort, maintaining a steady climate is a structural requirement for sensitive laboratory processes.
Microbial Growth Regulation: In incubation zones, temperature must be held with high-accuracy to ensure consistent results.
Product Stability: Prevents chemical degradation of moisture-sensitive powders or temperature-sensitive biologicals.
Static Prevention: Precise humidity control (typically 45% to 55% RH) is essential to prevent electrostatic discharge in sensitive electronics or powder handling.
Personnel Safety: Maintains a comfortable working environment for staff wearing multi-layered cleanroom suits.
Engineering Features & Integration
Metrolabs T/H Controllers are designed for the high-frequency cleaning cycles of sterile environments while providing sophisticated data management.
Flush-Mounted Hygienic Interface
Our controllers are designed to be installed level with your Modular Cleanroom Panels. Zero-Ledge Design: The smooth interface prevents dust accumulation and simplifies sterilization. Resistant Surfaces: The front fascia is engineered to withstand frequent wiping with alcohol and exposure to VHP.
Real-Time Data & Alarms
Transparency is vital for facility validation. High-Visibility Displays: Large, digital readouts allow staff to verify conditions at a glance. Audible & Visual Alerts: Immediate notification if conditions drift outside of the pre-set safety "dead-band."
Advanced PID Control Logic
Our systems utilize Proportional-Integral-Derivative (PID) logic to manage your HVAC equipment. Smooth Transitions: Prevents the "hunting" effect (constant overshooting/undershooting), leading to significant energy savings and long-term performance of your compressors and heaters. Dual-Channel Monitoring: Simultaneously manages heating/cooling coils and humidifiers/dehumidifiers for a balanced atmosphere.

The Metrolabs Advantage: Integrated Systems
At Metrolabs, we don’t just provide a thermostat; we provide a fully integrated environmental strategy. Our controllers are custom-programmed to work in perfect harmony with your Cleanroom AHU, Ducting, and Differential Pressure Sensors.
Audit-Ready Logging: Our digital controllers can be linked to central data loggers, providing the tamper-proof records required for FDA and WHO audits.
Multi-Zone Management: We can design a centralized control hub that monitors and adjusts multiple rooms from a single interface.
Custom Sensor Placement: Our engineers ensure sensors are placed in “representative zones”—away from door drafts or heat-generating equipment—to ensure the most accurate facility data.
