Cold Smoke Testing provides clear, visual evidence of airflow and leakage paths, enabling informed decisions for system adjustments. It enhances occupant safety, improves evacuation planning, and strengthens compliance with fire safety strategies.
Room Integrity Testing is performed to verify that spaces protected by fire suppression systems such as clean rooms, server rooms, or data centers are sufficiently airtight to contain suppression gas during an emergency. This ensures the system operates effectively in accordance with ISO 14520 and NFPA 2001 standards.
Our specialists assess the airtightness of the room or enclosure by measuring how long suppression gas can be retained without significant leakage. The process identifies any gaps or weaknesses in the enclosure, enabling corrective actions before the system is put into service.
A properly sealed room maximizes the efficiency of suppression systems, prevents premature gas loss, and ensures compliance with safety standards, protecting both assets and personnel.
CSI’s Thermal Imaging service uses infrared technology to detect and visualize temperature differences in building systems and components. This allows us to uncover hidden issues, such as water leaks, heat gain or loss, inadequate insulation, and electrical hotspots that can impact comfort, safety, and energy efficiency.
Our experts perform detailed thermal scans of targeted areas, including electrical panels, HVAC systems, building envelopes, and mechanical equipment. Using high-resolution thermal cameras, we capture and analyze temperature variations, generating visual reports with annotated images that clearly identify problem areas and recommend corrective actions.
By detecting problems early, thermal imaging helps prevent costly failures, improve energy efficiency, and maintain a safe environment. It supports preventive maintenance, enhances system reliability, and ensures optimal building performance, all without invasive inspections or downtime.
