This phenomenon will e Create fog at the entrance of the store Later this fog will turn into ice and snow in the cold store e Generate huge energy losses due to cold air going out of the cold room and warm air entering it e Cause a formation of ice on the ground All this will cost money to the company damage the quality of the goods affect the security of the worker etc After having studied these effects around door ways in cold stores Biddle has developed a product that can solve aforementioned problems to provide an open and clear doorway for optimum use and efficien cy of cold stores the MAT air curtain Open door with MAT Energy 22 5 kl s Water 12 l h Cold store 20 With Biddle cold store air curtain Multi Air stream Technology This special air curtain possesses various patents including the Multi Air stream Technology By producing three air streams the cold store air curtain creates a screen between the cold store and the front hall The air curtain draws in air from both the cold store and the front hall discharging both cold and warm air into the doorway These two air streams are used to break the free convection As they are blown through the patented rectifier they are not turbulent Moreover to avoid mixing between them they are blown parallel and at the same speed Then a third air stream made of air from the cold store relatively dried by the MAT will be2. Excellence in climate solutions Biddle sales offices amp distributors Biddle has a strong focus on providing innovative climate solutions to their customers In order to be able to offer optimum support worldwide we work closely together with highly skilled local distributors in countries where there is no Biddle sales office For a complete list of Biddle distributors you are invited to have a look at www biddle info biddle sales office distributor biddle Biddle BV P O Box 15 NL 9288 ZG Kootstertille the Netherlands tel export office Biddle 31 512 335524 fax export office Biddle 31 512 335554 export biddle nl www biddle info Eg E An air curtain without rectifier will not screen the complete opening The discharged air fans out and does not reach the floor causing turbulence in the air stream and allowing heat to flow out of the doorway To reach the floor the air curtain must discharge the air at a higher speed and as a result the unit produces considerable turbulence higher noise levels and consumes more energy An air curtain must discharge air in such a way that no warm air i e energy will disappear to the outside The air turbulences created by the fans is eliminated by the patented Biddle rectifier The air is discharged in a laminar stream Thanks to the optimum discharge pattern a relatively low air velocity is needed to reach the floor A Biddle air curtain does therefo
