End Gable Glazing: 8mm clear twinwall no drip polycarbonate panels, complete framing, glazing, and extrusion package (10 year warranty) Ventilation A. 1 – 48” Quietaire GCS slant wall exhaust fan 1.5hp: 22527 cfm ea. @ .10 SP 110V or 220V a. 1 fan is 2 speed and 1 fan is single speed both equipped with shutter and guard. Offering a minimum of 1.3 air exchanges per minute @ .10 inches of static pressure b. 1 – 2 speed fan motor for additional stage of cooling B. 1 – 39” Motorized Quietaire Shutter, located above cooling pad offers a fresh air intake at the minimum stage cooling C. 5 x 25 feet, Stainless Steel Quietaire Evaporative Cooling System with trough, plate and 6” thick pad. The 6” pad material offers maximum cooling. Uses a 65 / 15 degree water/air blow with a 420 per maximum face velocity. System is self-contained and does no require a reservoir tank. Includes sump pump and float valve for proper water level regulation. D. 5 x 25 feet, Automatic Wall Vent located behind the evaporative cooling system. Wall vent operates using a motorized rack & pinion drive system offering years of maintenance free operation. Includes 24 volt motor, mounts and vent boss. Includes extruded aluminum frame and 10 year warranted 8mm polycarbonate covering. Heating A. 1 – 250,000 BTU – L.P. Modine Gas Heater. (or equivalent) a. Modine model PTP250S Heater delivers 80% thermal efficiency in a small package. Featuring a stainless steel primary heat exchanger. Totally enclosed fan motors and all controls mounted inside the cabinet for protection from airborne moisture and dust. Comes set-up for LP gas, Natural gas conversion available. B. 4 – Horizontal Air Flow Fans (HAF) 18” – 3 bladed fans complete with guard and a split capacitor 115 volt 60 hz motor, 1.1 amps develops 1790 CFM. These fans circulate the air to maintain a consistent temperature inside the greenhouse, in addition, these fans reduce the stratification (stale air) thus reduces the risk of plant disease.
