Solutions
One design constraint runs through everything we build: replace legacy gas equipment when it is due anyway — without a service upgrade, a switchgear project, or a building that has to shut down.
01 / Rooftop electrification
Multi‑zone and dual‑deck gas/electric rooftops are the hardest equipment in any building to electrify, because they were only ever wired for cooling. Three engineered approaches, selected by what is actually on your roof.
Direct replacement for obsolete multi‑zone units of any legacy brand, built to the existing curb and ductwork with single‑point power.
Heating some zones while cooling others, all‑electric, on the connected power the building already has. Patent‑pending.
Intelligent demand and load management that keeps real operating current inside the existing feeder and breaker.
02 / Large rooftops
For 80–200 ton rooftop units serving VAV reheat or active chilled beam systems. Done at the moment the rooftops are replaced, the building’s gas boilers can be retired at the same time — without adding a single amp to connected power.
One rooftop unit consolidates what is normally five separate systems, in the footprint the old unit already occupied.
03 / Hydronic systems
Heating, cooling and domestic hot water on a single heat‑recovery loop. The cooling tower goes, the gas boiler goes, the water treatment program goes, and every room gets its own control.
20–300 ton hydronic plants with glycol‑free free cooling down to −13°F — without the pumping penalty, heat‑transfer derate and maintenance burden of a glycol loop.
Water-source heat pump buildings
Keep your existing water-source heat pumps. HydroCore replaces the cooling tower and gas boiler that hold the loop, and a heat pump makes domestic hot water from the same loop.
04 / Dedicated outdoor air
For large‑scale DOAS and data center outside‑air loads. Dry, neutral supply air at design conditions to 115°F, with a third to nearly half less mechanical cooling and no electric reheat coil on the schedule.
Pressure De-Coupled / Comfort cooling series
Central dehumidification. Individual zone comfort. Full mixed-air dehumidification with recovered-heat reheat at each zone and factory-integrated controls.
