A Thermic Fluid Heater (Thermal Oil Heater) is industrial heating equipment, used where only heat transfers are desired instead of pressure. In this equipment, thermic fluid is circulated in the entire system for heat transfers to the desired processes. Combustion process heats up the thermic fluid and this fluid carries and rejects heat to the desired fluid for concluding the processes. After rejecting it, this fluid comes back again to the thermic fluid heater and this cycle goes on.

MAHEK INDUSTRIES offers Thermic Fluid Heaters / Thermal Oil Heaters fired by extensive range of fuels. Thermic Fluid Heaters / Thermal Oil Heaters are available in both solid fuel firing as well as LDO / Gas / Dual fuel firing variants so that you get the advantage of economically available fuels.

FOUR PASS SOLID (COAL / WOOD) FUEL FIRED THERMIC FLUID HEATER

The Four Pass solid (coal / wood) fired Thermic Fluid Heater comprises of two heat exchangers namely radiant pass heat exchanger & convective pass heat exchanger. Radiant pass heat exchanger is a coil with conical shape & highly graded insulating material on outer surface to resist heat loss. Convective pass is made of two parallel concentric helical coils designed for sufficient convective heat transfer. This set of coils is covered with shell & this shell is insulated to resist heat loss. Radiant and convective heat exchangers are connected by a specially designed refractory duct which allows flue gas to pass from radiant to convective zone. Complete unit consist of radiant coil, convective pass, Fire chamber with sufficient grate area, F.D. fan for forced combustion, Air pre-heater to retrive tremendous amount of heat from flue gas and transfer it to combustion air, Multi-cyclone separator to separate ash particles from flue gas & I.D. fan to induce air from the system & pass it to chimney for exhaust.

We also design & manufacture Three Pass solid (coal / wood) fuel fired Thermic Fluid Heaters.

THREE PASS LDO / GAS FIRED THERMIC FLUID HEATER

This type of Thermic Fluid Heaters are either horizontal / vertical to suit the space availability. They are made of two parallel concentric helical coils designed for sufficient heat transfer. These are equipped with combustion burners using varied fuels like LDO, Natural Gas, LPG, Bio Gas, etc. Shell in shell jacket is provided as primary heat recovery device. The primary combustion air recovers the excess heat from flue gas and goes to burner head. Heavy oil are also used which are equipped with electric or media oil pre-heaters which are heated through nozzle heads or oil line systems before feeding them to burners.
