Sentech Refrigerant Monitors

SenTech Corporation Refrigerant Monitors 'early warning' loss detection

The Sentech refrigerant monitors are 'early warning' loss detection monitoring systems designed specifically for refrigerants. These environmental system IR-SNIF monitors are specialised refrigerant monitors that have been designed for applications such as comfort air, refrigeration and critical environment applications.

The IR-SNIF models are cost effective, self contained active air-draw sampling systems offereing highly reliable infrared-based performance with the flexibility to satisfy a wide range of continuous monitoring applications.

The monitors utilise NDIR [non-dispersive infrared] and pyroelectric [absorptive sensing] technology featuring multi-zone detection point capability from a single field-programmable self-contained metal enclosure featuring a unique built-in leak wait period that minimises nuisance false alarms.  

Suitable applications for the Sentech Refrigeration Leak Monitors are:

  • Supermarkets
  • Refrigerated warehousing
  • Industrial process cooling
  • Sports arenas
  • Agricultural process and stroage 
Comfort Air Applications Refrigerant Applicaitons Critical Environment Applicaitons
  • Office buildings
  • Hospitals
  • Schools & Universities
  • Factories
  • Government facilities
  • Supermarkets
  • Refrigerated warehousing
  • Industrial process cooling
  • Sports arenas
  • Agricultural process and stroage
  • Corporate data centres
  • Telecom switching factilities
  • Process control rooms
  • Industrial robotic systems
  • Medical diagnostic centres
  • Clean rooms
