Heresite’s P-413 Approved for NSF/ANSI 51 Rating

Heresite, a leader in the development of thin film corrosion resistant coatings, has now become the only company with a NSF/ANSI 51: Food Equipment Materials rated phenolic-epoxy for HVAC-R coils. The NSF rating establishes that Heresite’s P-413 coating has been shown to meet the requirements for materials and finishes used in the manufacture of commercial food processing equipment and its components.

The NSF/ANSI 51 certification supports Heresite’s specialization efforts in the food processing and food refrigeration markets. With this certification, manufacturers of cooling equipment used in the food processing industry can be reassured that P-413 will protect their equipment’s coils while meeting food safety standards.

“P-413 is an ideal coating for protecting food processing industry coils,” states Peter Hellman, General Manager for Heresite Protective Coatings. “It has been extensively tested against a wide variety of chemicals, and has been shown to provide protection in acidic environments as well as against the basic chemicals that are often used for sanitization.”
