High-Intensity UV Mercury Curing Tunnel for High-Gloss Oil-Based Coatings
Production Line Composition
This system is a standard in-line curing station, easily integrated into automated coating lines:
Infeed Conveyor Section: Synchronized belt or roller conveyor
UV Curing Chamber: Housing containing high-intensity medium-pressure mercury UV lamp arrays, optimized reflectors, and exhaust system
Outfeed Conveyor Section
Power & Control Cabinet: Central unit housing lamp power supplies (ballasts), cooling system controls, and PLC
Operator Interface: Touchscreen HMI for system control and monitoring
Product Overview
This High-Intensity UV Mercury Curing Tunnel is engineered specifically for the complete and rapid curing of oil-based coatings, varnishes, and inks on flat substrates. Utilizing a broad-spectrum medium-pressure mercury lamp, it delivers intense UV energy across a wide range (including 365nm, 385nm, 254nm), ensuring deep through-cure and excellent surface hardness for high-gloss finishes. Its robust design guarantees reliable, continuous operation in industrial painting and coating environments.

Frequently Asked Questions
Q1: Why is a mercury lamp better than LED for some oil-based coatings?
A: Many traditional oil-based coatings are formulated with photoinitiators that respond to a broad UV spectrum. Mercury lamps provide this full spectrum (including shorter wavelengths), ensuring complete curing throughout the coating layer, which is critical for achieving ultimate hardness and chemical resistance.
Q2: How do I determine the correct conveyor speed and UV dose?
A: The required dose depends on your specific coating. We can assist with lab tests or provide guidelines. The machine allows easy adjustment of power and speed to dial in the optimal parameters for your product.
Q3: Does this machine produce a lot of heat or ozone?
A: Mercury lamps generate significant IR heat and ozone. Our standard system includes effective air cooling and an exhaust to manage heat and remove ozone, protecting both the substrate and the operating environment.
Q4: Can this system cure water-based UV coatings as well?
A: Yes, it is highly effective. The broad spectrum and high intensity are also excellent for curing water-based UV coatings, offering great versatility.
Q5: What is the lamp replacement schedule and cost?
A: Typical lamp life is 1000-1500 hours. We provide guidance on maintenance schedules and offer genuine replacement lamps at competitive prices as part of our after-sales service.
