Dew Point Monitor

€540.00 incl. Vat

SKU: 1EACA22-90 Categories: ,
Active cooling systems with integrated dew point monitoring are crucial for preventing condensation, mold, and water damage, particularly in surface cooling (ceilings, walls) and industrial compressed air applications. By monitoring the ambient humidity and surface temperature, these systems calculate the dew point and adjust or interrupt cooling before moisture forms.
Key Components & Technologies
  • Dew Point Monitors/Sensors: Devices that continuously measure temperature and relative humidity (RH) to calculate the exact temperature at which condensation will occur.
  • Chilled Mirror Sensors: Used for high-precision, industrial-grade monitoring, these work by cooling a surface until condensation forms.
  • Capacitive Sensors (Polymer/Metal Oxide): Offer fast response times in HVAC and compressed air applications by measuring changes in dielectric properties.
  • Controllers: Act upon the sensor data, usually by closing valves on chilled water lines or shutting down cooling circuits (e.g., in data centers or server rooms).
Applications of Active Cooling with Dew Point Monitoring
  • Surface Cooling/HVAC: In ceiling or wall cooling, sensors like the Variotherm RT495 monitor moisture on cooling lines and close actuators if critical, preventing mold and damage.
  • Data Centers: Intelligent Power Distribution Units (PDUs) use sensors in hot/cold aisles to monitor and prevent condensation on equipment.
  • Compressed Air Systems: Pressure dew point sensors ensure that compressed air does not condense inside pipes, which would cause corrosion and equipment failure.
  • Industrial Processes: Used in furnaces, pharmaceutical manufacturing, and food storage to maintain specific, dry environments.
Benefits
  • Prevention of Condensation: Detects risk early to avoid corrosion, short circuits, or mold.
  • Energy Efficiency: Optimizes cooling, allowing for, for example, up to 90% energy savings in specialized data center cooling.
  • System Protection: Prevents damage in critical infrastructure.
Implementation Best Practices
  • Thermal Contact: Sensors must have excellent thermal contact with the pipe or surface being monitored.
  • Placement: Placed at critical locations where condensation is most likely to occur.
  • Calibration: Regular annual calibration is recommended for high accuracy.
  • Output Types: Modern sensors provide standard outputs (0-10V, 4-20mA, or Modbus) for integration with Building Management Systems (BMS).

Can be ordered with Heat pump or separately.

There may be a longer leadtime if ordered separate to a pump.
