Process Heat Products Tutco SureHeat understands industrial facilities are dependent upon productivity, safety, and efficiency. Every component, machine, and process impacts operational cost. In today’s industrial environments, meeting productivity goals can mean the difference between success and failure. As the need for higher temperatures has increased so has productivity demands. This is a problem for most air heaters. Reaching and maintaining temperatures quickly can result in dramatically reduced heater component life. The Tutco SureHeat process heat engineering team developed the innovative...

Air Sources To ensure longer heater life and safe operation, it is recommended that all guidelines are followed. Please read and understand the heater operating manual before use. Failure to follow guidelines can result in heater damage, failure or personal injury. Only use air or inert gases with electric air heaters. Never use volatile or combustible gases. Compressed air or regenerative blowers are required to supply air flow and prevent failure of the heater element. The air source should be clean and dry. Dirt, grease, oil, oil vapors and corrosive or reactive gases will damage the heater....

Steps to Selecting an Air Heater An electric air heater works by transferring electrical energy into a passing air stream. The power and amount of air flow needed determine how hot the air heater will get. Step 1: Determine Standard Flow-rate (SCFM) SCFM = CFM x (P + 14.7) / 14.7 Step 2: Calculate Power Requirement (kW) kW = SCFM x (Exit Temp - Inlet Temp) / 2500 or kW = SCFM x (Exit Temp - Inlet Temp) / 3000 x 1.2 Step 3: Check Performance Curve Step 4: Determine Heater Pressure Rating Step 5: Other Considerations - Supply Voltage - Physical Size - Mechanical Connections ACFM = Flow Rate (Cubic...

Air Heater Calculation Examples 20 PSIG Pressure Gauge Use the above information to calculate SCFM. SCFM = 15 x SCFM Air Flow Pressure Inlet Temp. Power Exit Temp. Heat To calculate power requirements; use the above example and desired exit temperature of 800°F. kW = 23 x (800°F - 70°F) / 2500 = 6.72kW

Recommended Heater Controls Heater control systems are critical for proper heater set-up and longer element life. Before turning the power on to any heater, it is essential to have the proper air flow through the heater. Only qualified professionals should install electric air heaters and controllers. Follow all applicable electrical codes and recommended wiring. Open-Loop (Manual) Control This simple method of control uses a manually operated power controller to apply a fixed voltage to the heating element. Using this system, the operator manually adjusts the controller to change heater temperature....

Heater Control Connection Examples: L2 L1 SCR Controller * Built-In Thermocouple Temperature Controller Part Number: F076361 Thermocouple Placement TC placement is very important. The exposed TC junction should be no further than 1” from the Serpentine element (Left). Take precaution to have the exposed element slightly above the center of the ceramic tube (Right).
