Because of the demand, Double L has added a larger size insulated shutter - the IS8 - which fits 50”/51” fans. The IS8 is an addition to the current product line of TopJet Insulated Shutters.
These insulated shutters have been tested by Mike Czarick, Extension Engineer, University of Georgia, and by
Dr. Mike Brumm, Swine Consultant of Brumm Swine Consultancy, Inc. of Minnesota. Results showed 20+ degree difference between the standard shutter and the insulated shutter and after 2+ days of below zero F temperatures there was no blade freeze-up; thus, providing great energy savings, a safer environment for your pigs, and less buildup of moisture in barns!
BESS Lab, University of Illinois, tested the insulated shutter for leakage at .125 static pressure and compared it to a standard shutter. The leakage with the insulated shutter was only 20 cfm compared to the standard shutter at 230 cfm.
The insulated shutter ships unassembled for ease of shipping.
It is available in 24”, 36”, and 50”/51” fan sizes.
