Sanitary Plate Heat Exchangers for Efficient, Hygienic Thermal Processing

APV sanitary plate heat exchangers are engineered to deliver exceptional thermal efficiency, reliable hygienic performance and long-term operational value for food, dairy, beverage, pharmaceutical and biotechnology processing applications. Designed to maximize heat transfer while minimizing energy consumption, they help manufacturers improve product quality, increase uptime and reduce operating costs across a wide range of thermal processes.

Backed by more than a century of heat transfer expertise, APV's legacy began with its founder, Richard Seligman, who invented the first commercial plate heat exchanger in 1923—an innovation that revolutionized thermal processing and laid the foundation for modern plate heat exchanger technology

Designed for heating, cooling, pasteurization, regeneration and energy recovery, APV plate heat exchangers utilize advanced corrugated plate technology and optimized flow patterns to achieve outstanding heat transfer efficiency. Their compact footprint, flexible modular design and sanitary construction simplify installation, support easy maintenance and enable processors to scale production while meeting demanding hygienic requirements.

Whether processing milk, yogurt, juice, sauces, protein beverages, pharmaceuticals or sensitive biotech products, APV sanitary plate heat exchangers provide precise temperature control while protecting product integrity and supporting consistent process performance. From pilot plants to large-scale production facilities, APV delivers scalable heat transfer solutions trusted by leading manufacturers, research institutions and universities around the world.

How the APV Plate Heat Exchanger Works

By combining large effective heat transfer surfaces with carefully engineered plate corrugations, APV sanitary plate heat exchangers create high turbulence at low velocity. This creates maximum, thermal efficiency and minimum fouling and pressure drop which enables precise temperature control, shorter processing times and reliable cleaning performance. Fully accessible plate packs and modular configurations allow easy maintenance and capacity adjustments, helping processors improve uptime, optimise energy use and adapt quickly to changing production demands.

APV Sanitary Plate Heat Exchangers operate using thin, corrugated stainlesssteel plates arranged to form alternating flow channels for hot and cold fluids. The fluids flow in a true counter‑current direction, maximising temperature differentials and thermal efficiency.

Gaskets seal the plates, preventing media mixing while also directing flow across the entire plate surface. Corrugation patterns induce turbulence, increasing heat transfer efficiency and reducing fouling. The fully accessible plate pack allows for quick inspection, cleaning and modification to meet changing process demands.

With multiple frame compression systems, versatile connection types, and specialized sanitary accessories, SPX FLOW meets diverse heat transfer challenges across the sanitary marketplace.
