Heater manifolds have internal passages, bends and dead corners. PTFE powder cannot coat the inside. PFA is pumped through the passages and fuses to the inner walls.
Material-selection service specifies PFA for internal coating. At each outage, the internal coating is inspected. Procurement buys the internally coated manifold. The result is a fully coated passage, because the melt-flowable PFA reaches the interior corners.
Heater manifolds have internal passages, bends and dead corners, and sintered PTFE cannot coat the inside because the powder does not flow into the corners. PFA is melt-flowable and is pumped or flowed through the passages, fusing to the inner walls. A filled PFA adds wear resistance. Material-selection service specifies PFA for internal coating. At each outage, the internal coating is inspected through access ports. The smooth surface does not let product stick. Procurement buys the internally coated manifold. The result is a fully coated passage that is also clean and easy to rinse, because the melt-flowable PFA coats the interior corners and bends evenly.
Food heaters foul with product. A smooth PFA coating resists fouling and makes CIP faster. PFA is FDA-compliant.
Material-selection service specifies the food-grade PFA. At each CIP cycle, the smooth surface rinses clean. Procurement buys the food-grade heater. The result is a clean, efficient heater, because the non-stick surface releases product.
Food and beverage heaters foul with product buildup, which insulates the heater and harbors bacteria. A smooth, non-stick PFA coating resists fouling and makes cleaning faster. PFA is FDA-compliant, and a filled PFA version adds wear resistance. Material-selection service specifies the food-grade PFA. At each CIP cycle, the smooth surface rinses clean. The coating reduces CIP time and chemical use. Procurement buys the food-grade heater. The result is a clean, efficient, sanitary heater, because the non-stick surface releases product and the smooth coat meets sanitary design.
PFA bonds mechanically to a blasted surface. A primer bond layer chemically bonds to the metal and the PFA, giving a stronger bond.
Material-selection service specifies the primer for critical heaters. At each outage, the coating is pull-tested. Procurement buys the primed heater. The result is a stronger bond, because the primer seals the interface.
PFA bonds mechanically to a blasted surface, but for maximum adhesion on critical heaters, a primer bond layer is applied first. The primer chemically bonds to the metal and to the PFA, giving a stronger bond than mechanical anchoring alone. Material-selection service specifies the primer for critical heaters. At each outage, the coating is pull-tested. The primer also reduces permeation at the interface. Procurement buys the primed heater. The result is a stronger bond, because the primer is the difference between a coat that stays and one that peels.
