Coating with Silicon & Teflon

Silicon & Teflon Coating has proliferated as an extremely effective industry in the production of materials like non-stick pans, safe packaging, & water-resistant clothing.

However, the operation & application of Silicon & Teflon coating results in the harmful byproduct of volatile organic compounds (VOCs). Many operators in the industry have confronted VOC reduction obstacles with traditional technology that does not properly eliminate harmful emissions.

In addition, standard filters corrode over time, losing efficiency and requiring expensive maintenance & replacement. As demonstrated by a recent case study, Air Clear can effectively meet the economic & environmental objectives of any Silicon & Teflon Coating Operation to treat VOC emission & optimize savings & performance.

Client:

Arlon Silicon Technologies

Location:

Bear, Delaware

Background:

Arlon operates large Silicon & Teflon Coating operations with continuous fiberglass & additional woven material with calendars

Objectives:

  • Destroy 98% + of VOCs
  • Utilize a cost-effective total system operation
  • Return sufficient energy to limit oven burner energy expenditures
  • Minimize production down time during installation of the new system

Solution:

Air Clear engineers designed, fabricated, & installed a two-chamber Regenerative Thermal Oxidizer (RTO) to treat the emissions from the coating process. The RTO was equipped with a hot bypass system, counter flow secondary air-to-air heat recovery exchangers, & an ambient air dilution valve for high LEL control. Air Clear successfully fulfilled emission requirements; exceeding 98% Destruction & Removal Efficiency (DRE) while producing approximately 7,900 SCFM of 375-400°F pre-heated ambient air for the drying/curing oven. The Exhaust Stack Emissions and overall is monitored by two Flame Ionization Device monitors placed at the inlet & outlet of the RTO to continuously record performance. The Lower Explosive Limit is also monitored on the outlet of the oven. The heat exchanger operates with greater than 68% effectiveness. Once in operation, the RTO operated with zero fuel input while providing the required hot air for the drying/curing oven.

Case Study

Air Clear’s Regenerative Thermal Oxidizer eliminates Volatile Organic Compounds & boosts savings for Arlon Silicon Technologies

The RTO system is a two-chamber design, with poppet valves fabricated & tuned by Air Clear. This feature allows Air Clear to meet greater than 98% Destruction & Removal Efficiency. The entire system was designed, fabricated & installed by Air Clear LLC located in Elkton Maryland. The system was installed in three weeks & was operational with the coating line operations within 36 hours of initial start-up. A PLC system was used to provide flexible, easy, remote operation of the RTO as well as the existing drying/curing oven as a complete system. In addition, Air Clear engineers can monitor & troubleshoot the system operation from anywhere in the World. Altogether, Air Clear delivered cutting edge technology that holistically met AST’s goals to eliminate VOCs, maximize energy efficiency, & ensure a durable cost-effective product from installation through operation.
