Anleitung Zusammenfassung


Description Compact, safe and versatile heating unit for heating air or inert gas up to 1400°F. The SH-Series is available in wattages from 6kW to 36kW, and can be use with compressed air or a regenerative blower. The SH heater is designed for closed-loop temperature control, with a solid-state relay or phase angle fired SCR power control. Sensors inside the heater sense both element temperature and inlet air temperature and limit heater voltage and prevent element burnout if airflow is suddenly reduced. With this system, full power may safely be applied to the system with zero airflow. If operated correctly, the heater element will operate continuously for 5000 hours or longer. Specifications • Max. Static Pressure: 10 PSI • Max. Exit Air Temp: 1400°F • Max. Inlet Air Temp: 130°F • Exit Connection: 1-1/2" NPT • Inlet Connection: 1-1/4” NPT • Control: Closed Loop: 4-20mADC or Pulsed DC (3-32V, etc.) • Over-Temp Circuit: Dual-Input Limit Card mounted on a 6” x 3.15” x 1.6” deep snap track. Mount track to control cabinet using two #8 mounting screws, drilled 5.63” O.C.

Follow all applicable electrical codes and use proper wiring. !• WARNING! Sensors are at or near line voltage. Use teflon jacketed, teflon insulated “K” thermocouple wire to connect heater sensors to the over-temperature board. !• BURN/FIRE/EXPLOSION HAZARD Do not use with or near explosive or reactive gases. Avoid contact with the side, or exposure to the exit-end, during or soon after operation. DO NOT USE NEAR VOLATILE OR COMBUSTIBLE MATERIALS. Page 1 OPERATING INSTRUCTIONS OMEGA Precautions !• Use filtered air. Avoid grease, oil, or oil vapors, corrosive or reactive gases which will damage heater. !• Use exposed junction type “K” thermocouple within one inch of the heater exit for good control. Installation and Wiring See attached drawings. WARNING! Sensors are at or near line voltage. Use teflon jacketed, teflon insulated “K” thermocouple wire to connect heater sensors to the over-temperature board. 1. Be sure heater is securely mounted. 2. Follow all applicable electrical codes when mounting and wiring heater and control components. Operation 1. Turn on air and set pressure or flow to desired operating level. 2. Turn on power to the over-temperature board. 3. Turn on power to the power controller. 4. Turn on power to the temperature controller. 5. Set desired temperature on temperature controller. During operation, with steady-state airflow, the exit temperature should not vary more than a few degrees from set point. Although the heater will not burn out with zero airflow, if the heater is operated in a vertical downward position and an airflow of 100 SCFH or below is run through the heater, the inlet temperature of the heater will exceed 150°F and the Over-temperature board will begin to limit power to the heater. To Shut Down: 1. Turn off power to the temperature controller and the power controller. 2. Allow air to continue to flow for a minimum of 1 minute or until exit air temperature is 150°C or less for safety. Continue airflow longer if hot equipment components present any potential hazard to personnel. 3. Turn off air to the system. Replacing Elements Before replacing the element assembly, determine the cause of the element failure. Prior to powering the system back up, make certain that the entire system is operating properly. Possible causes of element failure are: 1. Normal end of Life 2. Failure in Control System 3. Mechanical Damage to System REPLACEMENT PROCEDURE 1. Turn off power to the system. Follow lock-out/tag-out procedures. 2. Unscrew the 3 external housing screws and remove the stainless heater housing. 3. Unplug element from its socket and plug new element into the socket. 4. Slide the stainless heater housing back over the element and secure housing with the 3 external housing screws. Performance Curves The following curves show the maximum temperature performance of the SH-Series heater as measured by a “K” type thermocouple located within 1” of heater exit. Use of other temperature measuring devices or varying the distance of the measurement may cause different temperature readings. The heaters will not generate temperatures greater than indicated on the graph in and if used correctly will maintain operating life in excess of 5000 hours.
