Houston, TX, July 6, 2023 – RectorSeal LLC, a leading manufacturer of quality HVAC/R and plumbing products, is adding the Dust Free® Duality Mini Dual-Spectrum UV light designed for ductless systems and HVAC installations subject to confined spaces.

The dual-spectrum UV lights maximize sanitized surface areas, and the Duality’s VOC filter doubles its sanitizing power.

• Dual UV LED Arrays
• Dual UV Spectrums, UV-A and UV-C Irradiation
• Dual Sanitizing Options
  • o VOC Filter
  • o UV Coil Scrubbing
• Dual Input Voltage
  • o 120VAC
  • o 230 VAC
• Zero Ozone Emission
• Electronically Communtated Motor and Low Voltage Disconnect Tested and Qualified for Safe Indoor Applications

Installation features of the Duality Mini Dual-Spectrum UV light include durable adhesives for mounting and a clip-on airflow sensor that automatically and proactively powers the unit off and on. Its small size ensures maximum light coverage without sacrificing sanitizing performance.

“At RectorSeal, we take great pride in offering solutions for professional contractors that are easy to install, deliver outstanding performance, and offer operational flexibility,” said Karina Eureste, Product Development Manager at RectorSeal. “The Duality Dual-Spectrum UV light is designed to provide those solutions, especially in tight spaces where legacy UV lights might not be feasible.”

Since 1937, RectorSeal has offered products that have built a steadily growing and loyal following among contractors due to differentiated and proven product performance. Further, the company is often the first to tackle and solve challenges professional trade contractors face. In 2015, RectorSeal became part of CSW Industrials, Inc.
