AVOID CROSS CONTAMINATION - The BKI 2-door oven solution PassThrough ovens improve logistics in your kitchen and save time. If you place the PassThrough oven between the kitchen and the serving area, the oven can be loaded from the kitchen side and unloaded from the opposite side when the products are ready. This way, you form a sharp separation between the products to be cooked and the products already cooked - thus preventing cross contamination, for example when you handle poultry. BKI PassThrough ovens are available in single or double stack electric 61 and 101 series models.
