Traditional UV Curing System for Screen / Offset Ink with 3UV Modularized Cassettes
UV electronic transformer
It adopts European imported brands, comes with BUCK voltage stabilizing circuit, 10-100% stepless dimming, and has powerful operation protection, including over-current protection, over-heat protection, lamp disconnection protection, etc.
UV mercury lamp
American HANOVIA brand, the lamp is started with low voltage, which has little impact on the lamp startup, and the warranty is more than 1500 hours.
Electronic component
Using famous brands such as Japan's Mitsubishi, Switzerland's ABB, and the United States' VIE, the quality is guaranteed.
Fan
It adopts European crown fan, which has high pressure, large air volume, low noise and long life. The noise standard is below 85 decibels, which is in line with international standards.
Equipment Description
Three traditional UV lamps and cassettes equipped with control cabine( Fig. 1) and cooling device (Fig. 2, 3.), is used for curing inks using UV radiation sources.

Chiller System Includes: |
Protection devices such as: |
2. Weihui cooling fan. |
1. Cooling liquid level control device 2. High and low voltage control device 3. Flow(stream) detector |
LED-UV module parameters:
1. Smooth adjustment of UV radiation power in the range from 0 to 100%.
2. The operation of LED UV module is controlled using a touch screen with a one-touch interface.
3. LED UV elements operate only after signal confirmation from the feeder board sensors and cylinder impression-ON signal. Thus, LED UV module starts working only when printing starts. LED UV elements are completely turned off during the standby mode.
4. The system warns if the cooling liquid level is low, or if maintenance of cooling unit is required, or if the flow sensor detects a leakage.

UV LED Advantages
WT is a professional R&D and production of water cooled UV curing system, LED UV curing system enterprises.
WT has an array of UV lamp and LED products to meet almost any printing or converting need. All products can be integrated seamlessly by WT to fit your machine.
Print without limitations
Unlike UV lamps, LEDs emit little infrared heat towards the substrate. This avoids common issues such as high pile temperatures, curling of heat-sensitive materials and loss of moisture in paper.
Ultimate productivity and peace of mind
No moving parts for low maintenance and no warmup/cool-down mean less UV related downtime, which increases press productivity.
Reduced energy consumption
LED instant on-off means that no energy is consumed when the press is idle. The higher electrical efficiency of LEDs and the purity of UV output allow typical energy savings of over 70%, compared to H-UV or IR lamp systems.
No marking, no sealer or spray powder
UV LED inks and varnishes are 100% cured instantly after the LED lamp.
