Dual Atrium 

Commercial Greenhouse

Growers using the Dual Atrium have experienced reduced need for chemical and growth regulators, along with reduced operating costs by minimizing the need for use of cooling equipment. 

Outstanding Growing Conditions: 

  • The roof vent vertically opens to 85 degrees. 
  • With individual motors you have zone opening ability allowing you total flexibility in cooling and venting. 
  • Fewer obstructions than other full open roof style structures leading to higher light levels. 
  • Total versatility for all crops at all stages. 
  • Temperatures are within 1 degree of fully open roofs with significant reduction in cost and maintenance. 
  • The roof can close in less than three minutes.  

Venting In Inclement Weather: 

  • The patented Nex-Hood allows you partial roof opening in inclement weather. 
  • Able to open vent with snow in the valley. 

Expected Strength: 

  • The double tooth steel racks give you added strength at crucial stress points in windy conditions, and longer life than aluminum racks. 
  • The unique in-house roof extrusion design gives you the needed strength and heavier extrusions for North American conditions.  Competitive European designs typically do not meet U.S. snow and wind loads. 
  • Our in-house licensed engineering staff has designed a structure whose quality is consistent with all of our other structures and is compatible with all Prospiant style structures. 

Save Money and Maintenance: 

  • Growers using the Dual Atrium have experienced reduced need for chemical and growth regulators. 
  • Growers have reduced operating costs by minimizing the need for use of cooling equipment. 
  • Up to 50% less rack & pinions with 50% less motors than other open roof style structures, leading to lower initial cost, less maintenance and lower energy consumption. 
  • Up to 50% less gutters than full open roof style structures leading to lower initial costs meaning less shadows and less condensation points. 

New Side Ventilation Option:  

Along with our standard venting options of drop curtains or rack and pinion vents for the sides and ends, Prospiant can supply our new EDDG vent. The EDDG vent is a drop-down exterior guillotine vent that gives the owner the option of a clear vent opening incremented to the desired dimension. The vent can be covered with single or double wall polycarbonate or single or double polyethylene. Ask our experts about the EDDG vent to give you an “edge” over the traditional vent options.  

Highlights

  • Roof vent vertically opens to 85 degrees. 
  • Individual motors provide zone opening ability allowing you total flexibility in cooling and venting. 
  • Fewer obstructions than other full open roof style structures leading to higher light levels. 
  • Total versatility for all crops at all stages. 
  • Temperatures are within 1 degree of fully open roofs with significant reduction in cost and maintenance. 
  • The roof can close in less than three minutes.
