Electrify now. Keep your existing electrical service.

Replace hard-to-electrify rooftop equipment with solutions engineered around the curbs, ducts, and electrical capacity your building already has.

01 / What we build

Electrification without the electrical upgrade.

Most buildings cannot electrify because the service will not take the load. VRX equipment is engineered to replace legacy gas equipment at end of life within the electrical envelope the building already has.

Rooftop electrification

Multi-zone & dual deck

The hardest units in the building to electrify, replaced on the existing curb and inside the existing service. Three engineered approaches, selected by what is on your roof.

Three approaches →

80–200 ton rooftops

VRX-RTU

Retire the building’s gas boilers on the day the rooftop units are replaced — without adding a single amp to connected power. Serves VAV reheat and chilled beam.

Retire the boilers →

Whole-building heat recovery

HydroLoop

Heating, cooling and domestic hot water on one loop. No gas boiler, no cooling tower, no water treatment program, and room‑by‑room comfort control.

One loop →

Water-source heat pump buildings

WSHP Electrification

Keep the heat pumps, retire the gas. HydroCore replaces the cooling tower and boiler, and domestic hot water comes off the same loop.

02 / Watch it happen

03 / AI data centers

Cooling engineered around the constraint stack.

Water, community acceptance, capital timing and execution speed are the constraints that stall data center projects — not tonnage. HydroCore is a modular 300‑ton platform designed against all four, so CapEx follows demand instead of leading it.

04 / Built for the spec

Claims an engineer can defend.

VRX was founded by the builder of Alliance Air Products — organically grown into one of the major providers of data center cooling in the United States. We write performance and code‑compliance claims the way consulting engineers have to read them: evidence‑based, project‑specific, and reviewed against ASHRAE 90.1, ASHRAE 90.4 and California Title 24 pathways.
