Application

Prior to application, ensure the system is entirely free of contamination, such as mill scale, oil, rust, or grease. Incidental amounts of water will not interfere with VpCI®-649 BD Winterized RTU. Once ready, fill entire system with VpCI®-649 BD Winterized RTU. Dilution is not required or recommended. For use in operating systems, the recommended maximum temperature is 180°F (82°C). For storage or layup, it provides freeze protection down to a temperature of -31°F (-35°C).

For concentration monitoring, test by titration, refractometry, pH, or using a molybdate tracer.
