LED-WDZ devices are the most advanced UV radiation sources in the world, characterized by extremely high energy efficiency (about 30%), extremely high selectivity of effective wavelength (half-power wavelength broadband: 5nm), extremely long service life (40,000 hours), low infrared heat and no ozone, making them more suitable for the cross-linking and solidity of cross-linked polyolefin and other materials.
LED-WDZ type UV LED irradiation polyolefin cross-linked equipment adopts a circular cavity tunnel structure, installs a self-developed UV LED light source and forms a tunnel to the central area, whose radiant power can be infinitely set within the scope of 0~100%.
Structural features of LED-WDZ irradiation cross-linked equipment:
It pneumatically turns to enable the tunnel structure, which is easy for operation, cleaning and coiling;
It uses the intelligent touch-type human-computer interface to monitor data, and the power of operating buttons is set on the touch screen interface;
One push function co-exists with separate start;
It uses refrigerating fluid for cooling, and uses anti-freezing solution dedicated for automobiles as cycling medium;
It is connected to an external fume removal unit to exhaust fume to the outdoor through the air flue.
