New technology
New technology on site: we install what the specification names
Lithium UPS, VRF, PoE, busway, lighting control, IP field protocols, liquid-cooling infrastructure. Installed to the specification — no catalogue push, no tier sticker unless the contract names one.
HVAC
VRF · VRV
Variable refrigerant when a common CHW loop is not required.
EnergyMeters · VFD
kWh numbers before an energy report.
UPSLithium · VRLA
Room heat and escape routes first.
ELVPoE
Switch watt budget before 4K cameras.
DCBusway · liquid cooling
Technical infrastructure on the same programme as power and cooling.
ControlsPLC · SCADA
Factory automation and building DDC — I/O list first.
BMSBACnet/IP · MQTT
On a technical VLAN, not the lobby switch.
