CONVENTIONAL APPROACH
More devices. More interfaces.
- Multiple DX cooling units
- Standalone dehumidifiers
- Electric or gas reheat
- Separate stats, humidistats, or BMS logic
- More feeders, drains, controls, and service points
Cannabis grow room HVAC + dehumidification
Less equipment.
More yield.
Custom hot gas reheat HVACD for commercial grow rooms. Integrate cooling, dehumidification and PLC controls around your room loads, with available refrigeration heat recovered for reheat.

Engineered for real cultivation loads
The room is the system.
Lighting, canopy density, irrigation, airflow, and plant transpiration all shape the HVACD load. Yield Logic starts with the actual cultivation environment and builds the control strategy around it.
EXTREME SERIESBrushed stainless construction
Precision through integration
Dehumidify hard.
Hold the temperature.
Yield Logic cools the airstream below its dew point to remove moisture, then redirects available compressor heat to temper the dried air before it returns to the room. The PLC coordinates the sequence around room demand.

03REHEATReclaim available discharge heat
04RETURNDeliver conditioned air
Built for the finish
Control the conditions that protect saleable flower.
Stable temperature, humidity, dew point, and VPD support a repeatable late-flower strategy without forcing cooling and dehumidification equipment to fight each other.
Hold a drier finish
Continue removing moisture as sensible demand falls—especially during lights-off and late flower.
Reduce the equipment stack
Consolidate functions that may otherwise require multiple units, reheat devices, controllers, and connections.
Reclaim the heat
Use available refrigeration heat for reheat instead of purchasing the modeled reheat duty again.
Operate locally
Manage essential setpoints, staging, alarms, and sequences through the integrated internal PLC.
Environmental stability can support yield and quality potential, but crop outcomes depend on genetics, cultivation practices, airflow, sanitation, irrigation, and other facility factors. No yield improvement is guaranteed.
Custom-built around the operation
From the room load
to the crop plan.
Packaged and split configurations are selected around lighting load, plant moisture, day/night targets, outside design conditions, utilities, redundancy, access, and service strategy.
