Certain processes require indirect heating due to constraints such as combustion product effect, uniformity etc.

Radiant tube burners are used in such cases, however recuperation is essential to minimize the loss through flue.

Dhanaprakash innovated a " Cost Effective Radiant Recuperative Burner."

• More than 85% efficiency.

• Flue gas temperatures as low as 200ēC.

• Single ended tube, u-tube, versions available.

• Furnace temperatures upto 950ēC obtained.

• Fuels used --- Reliance LDO, Diesel, Kerosene LPG, Natural Gas.

• Long lasting radiant tubes  --  SS310, 410, Kanthal APM.

• Fully automatic burner.

• Custom designed solutions case to case basis.

• Direct substitution for electrical heating (Retrofit).

• Saves substantial cost.
