GDHP Series Gas Detectors

HVAC-R Application

The GDHP line of industrial gas detectors provides a robust, cost-effective solution, suitable for use in a variety of industrial applications. It features a selection of fixed point detectors available for combustible, toxic and refrigerant gases, as well as Oxygen level monitoring.

GDHP detectors are ATEX-certified for use in Zone 2. They are available with analogue (4-20mA) or addressable (Modbus RTU) output option and a selection of sensor technologies. The detectors are simple to install and operate. The high-visibility light indication allows for easy status monitoring, while their one-person, non-intrusive calibration and solderless sensor replacement features facilitate maintenance and eliminate the need for hot work or system downtime.

All GDHP detectors are equipped with a self-diagnostic function, which constantly monitors the condition of the sensor and signal lines, and alerts in case of fault. 

Benefits:

  • Maximum safety: The GDHP series is compliant with relevant EU standards (ATEX, EN 50270). 

  • Versatility: The wide variety of available gases and dual output options (4-20mA, Modbus RTU) make the GDHP series a perfect solution for different scale projects across various industries.

  • Cost-effective specification: GDHP detectors are designed to deliver maximum value and reliability. With a low initial investment, they effectively reduce overall project costs. Additionaly, the non-intrusive calibration feature, solderless replacable sensor option and self-monitoring technnology streamline the maintenance process and result in substantial savings.
