• Energy-saving Control: Electronic expansion valve + PID adaptive cooling adjustment, 25% lower power consumption than traditional models

4.2 Heating & Humidifying System

• Heater: Nickel-chromium finned heater with SSR non-contact control, fast response and long service life

• Humidifier: Boiler-type steam humidification with auto water supply, no overshoot and fast humidity response

• Water Requirement: Pure water / distilled water (≥10kΩ·cm); optional RO water purification system

5. Q8 Intelligent Control System

Lab Companion self-developed Q8 Touch Controller provides precise regulation, flexible programming and complete data management.

6. Core Advantage: Optimized Air Circulation System

Lab Companion adopts upgraded duct circulation design to eliminate temperature and humidity dead zones, especially suitable for precision electronic components.

• High-flow centrifugal fan + adjustable air deflector for uniform internal airflow

• Adjustable wind speed: 0.5~3.0m/s, avoiding direct strong wind impact on delicate samples

• 30% higher temperature uniformity and 20% faster humidity stabilization than traditional designs

• Ideal for PCB, chips, optical components and low thermal-mass products

7. Full Safety Protection

Multiple redundant protection mechanisms support long-term unattended operation.

• Dual over-temperature protection (mechanical + electronic)

• Compressor over-load, high/low pressure protection

• Phase sequence / phase loss protection

• Heater anti-dry burning protection

• Humidifier water shortage alarm & stop

• Leakage current protection and fan over-current protection

• Optional independent sample over-temperature monitoring
