Services
UPS Installation
End-to-end delivery for critical power projects, from site survey and system design through installation, commissioning, and handover.
What we supply
Three-phase UPS systems
Designed for data centre UPS environments, industrial sites and critical facilities. High-capacity resilience for business-critical infrastructure.
Modular / scalable UPS
Right-sized for your current demand, with capacity to expand as your load grows. Reduces over-specification and protects future investment.
Online double-conversion topology
Highest protection class with zero transfer time to battery. Stable output for sensitive equipment where continuity is non-negotiable.
Brands include Eaton, APC, Riello, Borri, Chloride and Emerson - specified independently based on your load, not margin.
UPS relocation service
Many organisations overlook UPS relocation service planning during office and site moves. Moving a live UPS incorrectly can damage equipment, void warranty terms and introduce serious safety risks. OnLiTECH manages the full de-commission, secure transport and re-commissioning process at your new location, including testing and sign-off so continuity is protected from day one.
