PL-L Series H-Shaped UV Lamp PL-L55W

If you want to procure cost-effective germicidal modules, sourcing from specialized China PL-L Series H-Shaped UV Lamp PL-L55W suppliers provides an optimal financial solution. Kingrate’s specialized H-shaped layout delivers uniform 170μW/cm² UV output across a 530mm profile, shrinking replacement frequencies by 30% compared to typical lamps.

Application Advantages in High-Flow Fluid Scenarios

Fluid disinfection relies on sufficient UVC exposure duration to kill all microorganisms. The extended 530mm arc length of PL-L Series H-Shaped UV Lamp PL-L55W prolongs water radiation contact time, thoroughly inactivating stubborn parasites including Giardia and Cryptosporidium.

Two core cost-saving structural merits of the 530mm long tube:

1. Reduce lamp installation quantity: Cut internal sockets and supporting ballast count by 25% vs short stacked lamps, lowering overall equipment cost.

2. Low flow resistance streamlined H-shape: Minimize hydrodynamic drag inside closed water circulation pipes and avoid abnormal pipeline pressure drop.

International Compliance

All PL-L55W lamps are manufactured under full ISO9001 quality management control, with complete CE, RoHS, REACH certification. 100% ozone-free quartz formulation generates no corrosive toxic gas, supporting 24/7 continuous manned indoor air disinfection without secondary air pollution risks.

Technical Advantages

Cheaper generic lamps usually experience erratic power drops when operating near 500mm in length. Kingrate counters this vulnerability through precise materials control:

• Ultra-High Transmittance Quartz Glass: Our tubes achieve over 90% transmission in the deep UVC range, ensuring energy-saving operation by preventing valuable light energy from being trapped as internal heat.

• Eco-Friendly Compliance: Fully certified under RoHS and REACH criteria, ensuring zero chemical residues and safe disposal routines at the end of the 9,000-hour operational cycle.

Operator FAQ

Q1: The lamp emits visible localized blue glow — does the brightness reflect actual UVC sterilization capacity?

A: Blue light is only a byproduct of mercury gas excitation; effective 253.7nm UVC is invisible to human eyes. Visible brightness cannot judge disinfection efficiency. A calibrated digital UVC radiometer is required to verify standard 170μW/cm² output.

Q2: Is PL-L Series H-Shaped UV Lamp PL-L55W compatible with common T5 fluorescent lighting electronic ballasts?

A: Strictly incompatible. Office fluorescent ballasts adopt totally different current-voltage characteristic curves. Driving this UV lamp with lighting ballasts either leads to rapid filament burnout within hours or complete startup failure due to insufficient ignition voltage.

Q3: What storage standards prevent micro-cracks on the long 530mm quartz tube?

A: Store lamps horizontally in original shock-absorbing corrugated sleeves, in dry, vibration-free warehouses. Do not stack more than 5 layers; excessive vertical pressure will create invisible micro stress fractures on the tube body, causing lamp rupture during operation.

Whole Manufacturing Process

At KINGRATE‘s modern production facility, every UV lamp goes through the following key stages, each handled by specialized equipment:

Filament Forming: Automatic Filament Manufacturing Machines

It all starts with the filament. Our automatic filament manufacturing machines precisely wind tungsten wire into filaments with consistent shape and turn count, ensuring uniform electrical performance from the very beginning.

Assembly & Sealing: Tube Clamping Machines

After the filament is assembled with the quartz tube and lead wires, the tube clamping machines fuse them together at high temperatures, creating a hermetic seal. Automated control ensures precise temperature and pressure, eliminating the risk of leakage.

Component Welding: Welding Machines

Internal leads and external pins are connected by spot welding machines, producing strong joints with low resistance. This ensures smooth current transmission and lays the foundation for a long service life.

Vacuum Exhaust: Exhaust Machines

The sealed tubes are then transferred to exhaust machines, where air is evacuated and a precise mixture of inert gases is filled. This step directly determines the gas purity and pressure inside the tube – a critical factor affecting UV output intensity.

Aging Testing: Aging Machines

Finished lamps are finally aged on aging machines under simulated operating conditions to stabilize performance and screen out early failures. Every batch undergoes thorough aging to ensure reliability before shipment.

Supporting Systems: Automatic Conveying, Inspection & Packaging

Throughout the above processes, automatic conveyors, online inspection systems, and automated packaging lines work together to form a complete modern assembly system, ensuring high efficiency and consistency while flexibly accommodating orders of various specifications.
