Product catalog summary
Overview: This document provides technical specifications and functionalities for various HVAC system components, including sensors, actuators, and controllers. It outlines the operational parameters and capabilities of each component, focusing on pressure, temperature, and humidity control.
Specifications:
  • Pressure/Differential Pressure Sensors: ExBin-P and RedBin-P models offer a range of 0 to 5,000 Pa, suitable for fan-belt and filter protection with 1- or 2-stage switching points. ExCos-P and RedCos-P models provide a full range adjustable from ±100 to ±7,500 Pa.
  • Temperature and Humidity Sensors: ExReg-D and ExCos-D models operate within a temperature range of -40°C to +125°C and 0 to 100% relative humidity, with full range adjustability.
  • Linear Valve Actuators: ExRun and RedRun models support forces from 500 to 10,000 N, with stroke lengths of 5 to 60 mm and operation speeds of 2 to 15 seconds per mm. They offer on-off, 3-position, and modulating control.
  • Failsafe Linear Valve Actuators: ExMax + LIN and RedMax + LIN models provide forces from 500 to 3,000 N, stroke lengths of 7.5 to 42 mm, and operation speeds of 0.1 to 15 seconds per mm, featuring spring return functionality.
  • Quarter Turn Actuators: ExMax and RedMax models offer torque ranges from 5 to 150 Nm and operation times of 3 to 150 seconds per 90°, with options for on-off, 3-position, modulating control, and spring return.
Applications: These components are designed for use in safe and hazardous areas, providing essential control and protection for HVAC systems, including air dampers, filters, heaters, fans, and humidifiers.
