Lead-free EVS 500LF targets those with one lead wave and one lead-free wave, those who use Nitrogen or want to reduce Nitrogen usage, those with selective solder pots who only remove small amounts of dross every hour, or those with multiple waves. Users can recover up to 80% of pure solder from waste dross. ISO14001-compatible system works with environmental control systems and also helps to reduce carbon footprint by utilizing latent heat already imputed to dross to help recovery process.
