Product Description

ANM75 series burners are line-type burners ideal for generating large volumes of clean, hot air. This series of burners was designed with modular concept; burner shape depended on local duct dimension, it can be designed best fit the process duct for even mixing. Applications include ovens, dryers, fume incinerators, and similar industrial equipment especially used in the food, gypsum industry.

Burner adopts a modular structure, each module size is 300×176.5 or 150 x 176.5 mm. According to the customer duct size, the burner could be designed as linear type, square, or cross in square to ensure a uniform temperature in the process air duct section.

ANM 75 Series is a patented product of Anderson Thermal Solutions
