Customized precision air conditioners prevent lost crops and maximize the investment in a grow room

Working in cooperation with a leading medical marijuana grow facillity, STULZ engineered a solution that solves the biggest problems facing modern grow rooms.


  • Maximize crop yield: advanced environmental control units maintain tight control of temperature, humidity, and CO2 content

  • Eliminate relative humidity spikes during lights off cycles: special dehumidifier controls set coil temperatures low while reducing the air flow rate to maximize moisture removal

  • Prevent the formation of white mold: deeper coil for enhanced dehumidification capabilities and tight moisture content control

  • Prevent pollen contamination: a growing pod pressure control system helps prevent pollen contamination that may lead to hermaphrodite plants

  • Pest control: integral UV lighting eliminates biological threats

  • CO2 augmentation: CO2 monitoring, alarm, and control with integral supply nozzle in the air stream

  • Corporate identity: custom unit paint colors

STULZ COS: Custom Precision Environmental Controls

STULZ floor mounted A/C's are designed to be the compact solution, providing precision temperature and humidity control for grow rooms, where continuous 24 hrs/day, 365 days/yr operation is required.

Smartly designed for 100% front service access, STULZ units can easily be tucked into a corner, between cabinetry, or side-by-side. 

  • 100% front service access
  • Fan speed is continuously adjustable via a signal from the system controller without the use of VFD’s
  • Direct drive - no belt abrasion/dust, maintenance free operation
  • Less vibration and quiet operation
  • Adjustable air volume
  • Power correction included

Advanced Dehumidification Features

Deeper coils and drain pans are specifically designed to aid in the removal of moisture from the grow space. STULZ's proprietary coil temperature control system lowers the temperature of the coil to just above freezing for short periods of time to rapidly reduce the moisture content in the space.  This helps prevent the formation of white mold.


Control and monitoring - E2 Controller

The E2 series microprocessor based controller continually monitors grow space conditions and maintains the proper temperature and relative humidity, utilizing STULZ's unique control method.

  • Precise control of temperature and humidity
  • Multiple I/O capabilities for all major components to optimize control for energy savings
  • Supports universal BMS interface for remote monitoring (address readable) and remote control (address writable)
  • Capable of networking controllers in a workgroup (pLAN) to work as one (no BMS required)
  • Pre-engineered controls for economizers and adiabatic cooling
