UL Approved Printed Circuit Board Heater High Temperature Resistance Material

SMT Reflow Oven Heater Chamber Printed circuit board heater

Tutco designed & supplied many kinds of heaters for reflow oven, SMT industrial for Heller & BTU etc,

Specifications:

• Voltage: 110V-600V
• Wattage: 3KW-12KW
• Type: Tubular, Open coil & Infrared
• Leakage, at rated voltage, between the frame, isolated from ground, and the supply terminals shall not exceed 0.5 milliamps after exposure to 29 to 32℃ at 85-90% relative humidity for 24 hours and while still under these conditions.
• The open coil element must withstand 2000 VAC/60S or 2500V/ 1S between current carrying parts and dead metal, must not be flashover or breakdown

• At 32±2°C & 70±5%RH, the insulating resistance value between current-carrying parts and interconnected non-current-carrying metal parts should be more than 100 MΩ.

• Switch off the heater after 10 minutes of heating same as when measuring the power rating. At this point the insulating resistance value when checking the resistance value should be immediately 100MΩ and be 100 MΩ after 10 minutes.

• Parts shall be made of SUS304, Mica plate, ceramic, and other high temperature resistance material;

• Heating elements shall perform their designed function during normal life testing with the following minimum reliability. There shall be no failures allowed during 3750 hours.

Why TUTCO
1. Heater is UL listed for Outdoor Applications
2. All of the limit controls in all TUTCO duct heaters are automatic resets or are manually resettable. There are no devices that have to be replaced when tripped.
3. In a horizontal airflow application, the airflow direction is not specific; it can go either direction without any modification.
4. With our wire rack element suspension system, the heater coil is less susceptible to airflow shading and allows a very small pressure drop across the coils.
5. All TUTCO duct heaters carry a zero clearance rating for installations into ducts.
