GENERAL INFORMA ION
Your Nieco ExVection™ high speed toaster features advanced technology which allows toast times unprecedented in the food service
industry. ExVection™ is Nieco’s exclusive patented technology that reclaims previously wasted heat and refocuses it on the product. The
result is a highly effective and efficient means of toasting product at speeds previously unheard of. Typically when the product is heated,
moisture escapes and forms a layer that acts as an insulator from the heat source. With ExVection technology™ the moisture barrier is
dispensed allowing better heat transfer and toasting. The efficiency obtained by utilizing an ExVection™ toaster adds up to big dollar sav-
ings as well as a better product and increased customer satisfaction. Boasting typical toast times ranging from 10 - 14 seconds, your cus-
tomers will never have to wait for a toasted product. Solid construction, high grade materials including metal sheathed heating elements,
contribute to an ultra-reliable toaster maximizing the return on your investment and providing years of trouble free service.
