Multi-Zone Fixed Point Refrigerant Leak Monitors
The new multi zone gas leak monitor for halogen and ammonia refrigerant gases provide monitoring for low level conditions of CFC, HCFC, HFC and ammonia refrigerant gases used in most commercial refrigerant systems. This state of the art product leads the industry in performance, cost of ownership, integration capabilities and cost.
Performance
- Fastest response time for quick detection of gas leaks for immediate response
- Longest sampling distance of up to 1,200 feet
- 38 refrigerant gas library
Cost of Ownership
- Fresh air calibration to ambient air, no calibration gas required
- Infrared sensing technology gives long sensor life and eliminates false alarms
- Limited maintenance with automatic re-zeroing to eliminate the need for calibration and simple annual filter replacement
Integration
- Integration of remote display (RDM) into front panel permits setup, configuration and diagnostics without a laptop or remote display
- Universal voltage switching power supply that works with any voltage without concern of frequency
- Building management system compatibility to interact with popular communication protocols
Acquisition cost
- Integration of remote display into front panel eliminates the need for additional accessories, laptop or remote display to program
- Longest sampling distance eliminates the need to purchase additional monitors
