• 10, 20 Profile Memory
• Multi Input Multi Output (MIMO)
• PID Controlling Action.
• Micro processor based programable controller.
• one burner, one thermocouple forms one pair as zone, thus multi zone control
• Digital display for time temprature graph online with USB pendrive for data storage, Wired lan PC connectivity for real time graph printing

• High Velocity Short Flame Burner
• Direct On/Off pulse firing effect.
• Smokeless perfect combustion

The furnaces are calibrated for uniformity as per API 6A Standard ( The Temperature Difference Between Highest & Lowest Points at Stabilised Conditions should not be more than 13C.)

• Trolley - movement by geared motor with brake.
• Door - movement by geared motor with brake, counter weighed,
• Door Lock Unlock - innovative, Pneumatically operated instant latching unlatching for perfect sealing

• Strong rigid construction
• Heat resistant grade CI castings at door and frame, bogie and furnace interface eliminates warpage.
• Railway rails for load bearing under temperature.
• Double sealing minimising heat losses.

• High temperature high density ceramic fibre modular lining.
• Self supporting U-fold door lining.

• All fuel fired furnaces are equiped with recuperator to recover the heat from flue gases by preheating combustion air. By thumb rule a rise of 150 degree C in combustion air 7.5% heat is recovered.

• Large furnaces handle high value materials, it is essential to install PLC for opration to avoid manual errors.
• PLC checks each & every operation prior to loading of materials called booting to ensure air/gas/power etc. are within the specifications & all the sensors are in working condition
• PLC monitors each & every operation during auto cycle for supply conditions, flue temperatures burner operations any deviation is automatically notified audio visualy & through SCADA
• PLC keeps event history for the record

• Aesthetically powder coated control panel.
• Electrical switch gears for drives, burners.
• Status indication and control.
• Burner sequence controller and flame failure device.
• Programmable startup, burner, temperature controlling system.

• Thermal survey as per API 6A Standard.
• All measuring instruments calibrated to national traceability

Construction:The unit has an outer body made up of MS with epoxy powder coat finish & a door with a heat resistant handle. The unit has a double walled type construction with the muffles body at centre of the furnace & the control box at top with 1"solid spacer in between. A coil type Heater of Kanthal/Nichrothal wire wound on the muffle with cerewool blanket serves as the heating element. A brick insulation+ ceramicwool +high density mineral wool insulation of 4" is also given to have skin temp.of furnace less than 50C. The door is provided with heavy-duty hinges and latch-catch lock system to open/close the furnace.

Control panel:It is located at the top of furnace and includes a Auto tuned PID Microprocessor based temperature controller cum indicator with Cr/Al Thermocouples controls heating process.Power:230V or 440V, 50 Hz as per requirements. Control will be SSR output type. Safety Fuse with MCB for power is also provided.

Time proportionate bands, data logger & cyclic timer, real clock battery backup, RAM memory, printer & PC interface controller with Cr-Al thermocouple sensor can be provided with the unit at Extra cost. Our technology is fully controlled, easy to handle, user friendly, intelligent and reliable.
We can also supply Universal Testing Machines, Compression Testing Machines, Tensile Testing Machines, Chain and Rope Testing Machines, Spring Testing Machines, Vickers / Brinell / Rockwell Hardness Testing Machines, Dynamic Balancing Machines, Dynamic Hardness Testers, Impact Testing Machines, Torsion & Fatigue Testing Machines & Special purpose Material Testing Machines, etc.We reserve the rights to change the above specifications without any notice due to constant improvements in design.
