Tek Troniks Refrigerant gas leak detection systems are designed to meet the stringent needs of the FGAS regulations.

Each gas sensor is calibrated at factory to be gas specific and has audible and LED alarm notification capabilities. Units are designed to be simple to re-calibrate onsite or at our factory. However calibration can be achieved by comparison to a known gas in air at the installation location.

Tek Troniks gas sensors are constant monitoring sensors, no tubing, suction or remote analysis is required. The sensors are designed to be; compact, robust, accurate and to be easily installed within the common locations that require monitoring in refrigeration and air conditioning locations.

At a glance:

  • Can be Standalone or Networked
  • 0-2V, 0-10V, 4-20mA & Volt-free outputs
  • Internal Alarm
  • Simple to Calibrate
  • Robust & Easy to Install

Stand Alone Leak Detection

The standalone sensor is pre-calibrated to the required gas at the location to be monitored. The sensor is designed to be easily installed with the option of an internal or external sensor head.

Each sensor has pre-defined alarm set points, on alarm the unit can be configured to create an audible warning and/or a red internal warning light will illuminate. The alarm will continue until the gas levels detected falls below the alarm set point.

Sensors can be calibrated in situ or returned to the factory for recalibration.


Connection to Tek Troniks
& 3rd Party Monitors / Controllers / BMS

For 3rd party connections the sensor can output alarm notifications via Digital & Linear output connections. Live data can also be streamed via the linear outputs for interpretation by the connected system.

Power for the gas sensor can come from a fused spur or the connecting unit, depending on the connection type. The sensor can be set to create an audible and visual alarm notification if required.

As with standalone systems the sensors are pre-calibrated to the required refrigerant and can be easily recalibrated, at the request of the customer.


Tek Troniks Wireless Monitoring

The gas leak detectors can be connected to Tek Troniks Wireless Monitoring Systems using wireless transmitters to form a standalone refrigerant leak detection system or with other sensor types to form a comprehensive monitoring system.

Tek Troniks Wireless Bridge also has the capability to communicate with refrigerant leak detection sensors providing a wireless solution to 3rd party BMS system where required.

The sensor head requires constant power that can be drawn from a fused spur connection, the sensors are pre-calibrated to the required gas prior to installation. Recalibration is the same as for the standalone and hardwired systems above.


F Gas Leak Requirements

In 2014 the latest version of the fluorinated greenhouse gases “F Gas” regulations came into existence, these legislation impact all users of affected HFC's including the refrigeration & air-conditioning sector.

The responsibilities for leaks of the affected refrigerants falls on the equipment users, in effect you. It also falls on the users to ensure all equipment is checked for leaks and, depending on the levels of refrigerants you hold, this check period could be at a maximum period of every 3 months.

The number of leak detection systems installed depends on the volume of F Gases used. Your check requirement intervals may decrease depending on the amount of systems installed.

Calibration of Gas Sensors

Tek Troniks refrigerant leak detection sensors are shipped pre-calibrated to the gas for which they are being used to monitor. Tek Troniks recommend that gas sensors should be calibrated at least annually to ensure they are still within their manufacturing tolerances. Periodic bump tests on the sensors should also be completed regularly to ensure all aspects of the leak sensors are working correctly.

Recalibration can be completed on site – Tek Troniks supply a calibration kit which simplifies this process.

Alternatively Tek Troniks supply pre-calibrated sensor heads to replace the on-site units, changing the sensor head is a quick and simple process that greatly reduces the time on-site. Saving on system downtime and calibration labour costs.
