Wherguard 360 Thermal Spray Coatings by Whertec
360˚ of Protection and Performance A Simple Solution That Simply Works.
Minimize Repair and Maintenance Costs with the WherGuard Coating System™ When it comes to paper and pulp operations the old adage “time is money” still applies. Equipment downtime – even for scheduled maintenance – is time that impacts profitability. The WherGuard Coating System, allows you to protect the surfaces of vital equipment against unplanned repairs while also simplifying regular maintenance. And it’s all done with a single convenient and effective formula...WherGuard 360™.
Our automated system utilizes the TWAS (arc spray) process for applying coatings in Kraft Process digesters (batch and continuous), evaporators and most tanks in the pulp and paper industry. Because the process is automated, crews are able to work outside vessels and accurately monitor coating thickness for uniformity. This means WherGuard 360‘ is applied safely, efficiently and evenly on small, large or even localized areas such as weld seams, extraction zones and screen areas. All coating applications are completed as recommended by TAPPI‘s guidelines for Thermal Spray Coatings for corrosion protection of pulp and paper mill process equipment.
