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
