Comfort cooling series
VRX LatentZone
Central dehumidification.
Individual zone comfort.
For new construction and for replacing existing units.
One system / Two comfort needs
Remove moisture centrally. Adjust temperature by zone.
LatentZone handles dehumidification in the central mixed-air stream, then uses recovered heat to bring every zone to its own setpoint. Each zone receives dehumidified air at a temperature suited to its comfort needs, without a gas boiler.
Full mixed-air dehumidification
Return air and outdoor air are treated together to remove moisture before the air is delivered to the zones.
Recovered-heat reheat
Heat recovered inside the system, not boiler heat, brings each zone to temperature, so different parts of the building stay comfortable at the same time.
Factory-integrated controls
Central dehumidification and zone temperature control are coordinated as one integrated system.
Two configurations / One outcome
Selected by zone count.
Both configurations deliver the same LatentZone result. The number of zones and the system type decide which one fits, whether the building is new or the existing units are due for replacement.
- New construction, or direct replacement of existing multi-zone units
- Individual reheat for every zone
- Built on the Pressure De-Coupled platform
- New construction, or direct replacement of dual-deck multi-zone units
- On replacements, the existing damper section, duct runs and zone thermostats can stay where their condition allows
- All refrigerant stays on the roof, nothing above ceilings
| LatentZone PD | LatentZone DD | |
|---|---|---|
| Zones | Up to 8 | Dual-deck systems, including 8+ zones |
| Applications | New construction and multi-zone replacement | New construction and dual-deck replacement |
| Zone temperature | Individual reheat for each zone | Warm and cool decks blended at each zone |
| Zone controls | Factory-integrated | Standard zone thermostats and actuators; existing ones can be reused on replacements |
| Airflow | Per project | Constant volume standard, variable air volume option |
| Heating season | Heat-pump heating | Recovered-heat warm-up, optional humidification |
| Gas boiler | None | None |
LatentZone DD / For larger buildings
More zones. Less to change.
One rooftop unit, many zones. LatentZone DD brings central dehumidification and recovered-heat comfort to new buildings with simple air-side zoning, and to existing dual-deck buildings while keeping what already works below the roof.
Past 8 zones
Zone count is set by the damper section, not by the refrigeration system.
Simple zoning, new or existing
New buildings get standard zone dampers and thermostats; on replacements, duct runs and controls can stay in place.
Refrigerant stays on the roof
No refrigerant piping or valves in occupied spaces.
Year-round comfort
Dehumidification in the cooling season and recovered-heat warm-up in the heating season, with no gas boiler.
Constant volume as standard. Variable air volume available where the project calls for lower fan energy.

Need operating-room humidity and filtration?
CriticalZone applies the same central-dehumidification approach to healthcare and surgical suites, adding humidification and HEPA filtration.
