Detection of refrigerant gas leaks

Industrial system with 11 CAREL GLD gas leakage sensors, serially connected to a boss mini supervisor

Our system consists of a boss-mini and GLD small gas detectors located in the devices of the system.

1 – boss-mini 

Boss-mini is the compact supervisor that allows you to monitor your system anywhere, anytime:

  • Connection with multiple GLD small sensors via RS-485 serial line with length up to one kilometer,
  • display and historicization for more than one year of the concentration of refrigerant gas present in each controlled room with detailed graphs and on settable time periods,
  • access to all historical data on Boss Mini both in local LAN network and via WEB from device (PC, Tablet, Smartphone),
  • notification of alarms to multiple users by e-mail and/or with messaging app,
  • possibility to generate periodic summary printouts with settable time intervals (every day, week, month etc …).

2 – GLD small sensors

The range of GLD series detectors is available for many refrigerant gases:

TypeSupported refrigerant gases
Type 1R-32 – R-407A – R-407C – R-407F – R-410A – R-448A – R-449A – R-452A – R-452B – R-454A – R-454B – R-454C – R-455A – R-464A – R-465A – R-466A – R-468A – R-507A
Type 2R-22 – R-134a – R-404A – R-450A – R-513A – R-1234yf – R-1234ze – R-1233zde
Type 3R-50 – R-290 – R-600A – R-1150 – R-1270

The range of GLD sensors allows connection with a supervision system, via a RS-485 Modbus RTU serial port. When leakage beyond a certain concentration is detected, the sensor sends a signal to the control or supervisor connected to it. The alarm is also displayed locally with an acoustic and visual signal.

GLD small sensors can also be used locally from smartphone thanks to the RILEVA TE app.
