Challenge

The rapid growth of air conditioning and heat pump systems, particularly those using modern, lower-GWP refrigerants, has increased the risk of undetected refrigerant gas leaks in occupied spaces. Many of these gases are asphyxiants, toxic at certain concentrations, or flammable, creating serious safety and operational hazards.

Traditional leak detection approaches often rely on periodic manual inspections or legacy sensors that can drift over time, require frequent calibration, or produce false alarms. This creates gaps in protection, increases maintenance costs, and makes it difficult for building owners and operators to confidently meet evolving safety standards such as BS EN 378, F-Gas, and BREEAM POL 01 regulations.

As a result, there is a growing need for continuous, reliable, and low-maintenance monitoring that ensures early detection while minimizing operational burden.

Solution

The AquiTron AT-SRG refrigerant gas sensor, utilizing advanced sensing technology from NevadaNano, provides continuous, accurate, and maintenance-free monitoring of refrigerant gases in occupied environments.

The AT-SRG is designed for straightforward deployment within HVAC and refrigeration systems, where it continuously samples ambient air and detects the presence of common refrigerants such as R32, R410A, and R290. When a leak is detected, the sensor delivers real-time alerts through integrated audible and visual alarms and system outputs, enabling immediate response.

Its robust design allows for:

• Seamless integration into building management systems (BMS)
• Long operational life without routine calibration
• High selectivity, minimizing false alarms from non-refrigerant substances

This enables facility managers, OEMs, and contractors to implement scalable, always-on leak detection across a wide range of commercial and residential applications.

Impact  

By enabling continuous, reliable refrigerant monitoring, the AquiTron AT-SRG delivers measurable benefits aligned with NevadaNano’s mission to protect people, property, and the planet:

• Enhanced safety: Early leak detection reduces the risk of occupant exposure to hazardous or flammable gases
• Regulatory compliance: Supports adherence to international safety and environmental standards, including BS EN 378, F-Gas, BREEAM POL 01, and ASHRAE requirements
• Reduced downtime and maintenance costs: Eliminates frequent calibration needs and minimizes false alarms, improving operational efficiency, supported by a 15+ year sensor lifecycle
• Environmental protection: Rapid detection helps limit refrigerant emissions, reducing environmental impact and supporting decarbonization goals

Ultimately, the AT-SRG transforms refrigerant leak detection from a reactive process into a proactive, intelligent safety layer, helping organizations safeguard people, assets, and the environment.
