Refrigerant leaks are more than a nuisance — they can lead to equipment failure, safety hazards, environmental impact, and compliance issues. Engineers responsible for designing and maintaining chiller plants, cold storage, or mechanical rooms need reliable refrigerant detection that doesn’t just meet minimum requirements but ensures long-term accuracy and ease of integration.

Macurco’s new AireShield Refrigerant Monitor brings a step-change in detection performance. Built on advanced NDIR (Non-Dispersive Infrared) sensor technology, AireShield is engineered for accuracy, durability, and ease of use, making it a compelling option for engineers looking to improve safety and reduce maintenance costs.

Key Features Engineers Should Know

1. NDIR Smart Sensor with Temperature Compensation

Traditional MOS (metal-oxide semiconductor) sensors often suffer from drift, false alarms, and high maintenance needs. The AireShield’s NDIR sensor provides precise
refrigerant detection with dramatically fewer false alarms. Temperature compensation ensures accuracy across varying operating conditions.

2. Field-Replaceable Smart Sensors

Engineers can swap out sensors without recalibrating the entire unit, reducing downtime and simplifying maintenance.

3. Flexible Integration Options

Analog Outputs: 4–20 mA or 0–20 mA
Digital Output: Modbus RTU
Relay Outputs: 5A SPDT & 0.5A relays capable of driving fans, valves, horns, strobes, or louvers.
This makes AireShield adaptable for both standalone safety applications and integration into BAS (Building Automation Systems) or control panels.

4. Visual and Audible Alerts

RGB LED notifications for alarm, warning, trouble, calibration, and Bluetooth connectivity.
Optional >90 dBA buzzer for immediate local alerts.

5. Rugged and Flexible Installation

Housed in a NEMA4X/IP65 enclosure, the unit is built for demanding environments like chiller rooms, walk-in coolers, or even ice rinks.
Supports up to two remote sensors per transmitter, extending coverage without additional control hardware.

6. Compliance and Reliability

Designed to not only meet but exceed code and regulatory requirements.
Event logging ensures traceability for compliance audits.

Applications

The AireShield is designed for environments where refrigerant leaks pose both safety and economic risks, such as:

Chiller & mechanical rooms
Walk-in coolers and cold storage
Food & beverage process cooling
Ice rinks
Ships and other marine HVAC systems
Industrial refrigeration facilities

Why Engineers Should Consider AireShield

Lower total cost of ownership – long sensor lifespan and reduced false alarms.
Easier compliance – built-in event logging and standards-based calibration.
Scalable integration – from a single chiller room to complex BAS-driven facilities.
Future-proof design – supports a wide range of refrigerants, including HFOs (e.g., R-1234yf, R-454B) and natural refrigerants like CO₂ (R-744) and ammonia (R-717).

The Macurco AireShield Refrigerant Monitor stands out as a modern, engineer-friendly solution for refrigerant detection. By combining advanced NDIR technology, smart sensor design, and versatile integration options, AireShield reduces maintenance burdens while ensuring compliance and safety in critical HVAC and refrigeration applications.

With AireShield, engineers get fewer false alarms, easier maintenance, and a lower total cost of ownership — without compromising safety.
