4ON CRITICAL INFRASTRUCTURE
Installation
4ON installs critical power, electrical, cooling, security and fire systems for technical and commercial environments. We can handle a single equipment replacement or coordinate a larger programme where several systems need to work together.
Generators
Generation systems can be supplied for purchase or hire, installed with appropriate controls, fuel systems, switchgear and testing.
Fire detection and suppression
We install early warning detection and waterless suppression technologies suited to environments where equipment protection and rapid response are critical.
Security, access and CCTV
Access control, CCTV, secure doors, barriers, intercoms and perimeter systems can be integrated into a wider technical build.
HVAC
Cooling options include DX, chilled water, fresh air, containment and adiabatic systems selected around heat load, resilience and energy efficiency.
Electrical
Distribution, switchgear, transformers, backup supplies and associated protection can be designed, installed, tested and maintained as part of the same project.
