Manufactured using superior quality components and materials, these products are very durable and offer excellent combustion system. Our vendors make use of advanced machines to manufacture these products. Featured with high performance, these burners are widely demanded by various industries for preheated air in oil dia-thermic generators and heat recovery systems. To cater to the demands of our clients, we offer these Dual Block Burners in various specifications. We are able to deliver these products within a specific time-frame at reasonable prices.

Other details Of Dual Block Burners:

The industrial burners ER series are designed particularly for water tube boilers used in big civil installations and industrial processes with a remarkable thermal demand. These series allows to realize a modular and flexible combustion system adding a preparation fuel unit (regulation pressure group set, preheating/pumping oil station), a gas train, a control panel and a fan. It can also be used a preheated air as in the oil dia-thermic generators and other heat recovery systems. The modulating regulation always allows to reach a wide modulation ratio and optimal fluid dynamics conditions for a good combustion.
