Calectro Duct Smoke Detectors
Advanced HVAC Smoke Detection, Now Available Through Hilberts
Hilberts is proud to represent Calectro, a Swedish manufacturer with more than 50 years of expertise in HVAC smoke detection. Their flagship product, the Calectro Uniguard 8, brings a smarter, more compact, and more service friendly approach to duct smoke detection for commercial and industrial HVAC systems.
A Smarter Duct Smoke Detector for Modern HVAC Systems
The Calectro Uniguard 8 is an optical duct smoke detector designed for today’s commercial buildings, industrial facilities, healthcare environments, schools, and retrofit projects. Known as one of the smallest duct smoke detectors in the world, the UG8 combines advanced detection technology with a rugged, compact design that helps simplify installation, reduce service needs, and improve long term reliability.
The Uniguard 8 is UL and ULC listed and designed to meet key code requirements including NFPA 90A, NFPA 72, and NFPA 101.
Why Contractors and Engineers Choose Calectro
One Hole Installation
The Uniguard 8 uses Calectro’s PST195 venturi sampling tube, a universal tube designed to fit all duct sizes with only one drilled hole. This helps reduce installation time, limits duct penetration, and eliminates the need for cutting or sizing tubes in the field.
360 Degree Rotating Housing
The rotating detector housing allows the unit to be positioned at nearly any angle, making installation easier in tight mechanical rooms, confined ceiling spaces, and challenging duct configurations.
Automatic Daily Calibration
The UG8 automatically calibrates each day to account for ambient air conditions, dust buildup, and environmental changes. This helps reduce nuisance alarms and supports more reliable smoke detection over time.
Reliable Airflow Performance
The Uniguard 8 detects smoke across a wide airflow range, from low velocity systems to high pressure commercial HVAC applications. This makes it a strong fit for VAV systems, retrofit projects, and complex mechanical designs.
Built for Demanding Environments
With an IP65 rated housing, the UG8 is protected against dust and water jets, making it a dependable choice for industrial facilities, healthcare settings, food service environments, and other demanding HVAC applications.
Visual Placement: Add a feature grid with icons for installation, airflow, calibration, BAS integration, durability, and service alerts.
