In 2015 T&T was contacted by a customer in Wisconsin with a very old Alto direct fired tunnel oven that they used for pizza crust baking. The oven was over 40 years old, with a 4 way FM air proof cock system.
Their complaint was uneven, inconsistent baking, inability to raise temperature and difficulty lighting the burners.
T&T upgraded the burner system with an all new Individual burner flame management and ignition system in 2016. The results are shown in the after pictures.
T&T also brought this very old baking oven in to NFPA safety compliance.
With improved baking quality, their sales increased resulting in their ability to build a new building expansion and order a brand new oven, doubling the the capacity of their existing direct fired pizza oven.
T&T delivered this new oven in 2018, starting it up within 5 days.
The customer was extremely pleased, as seen in their testimonial.
