In the Biotech & Pharma industry, PHEs are critical for precise temperature control, which is essential for product integrity and safety.

They are used for various applications, including heating and cooling pharmaceutical products like fluids, solutions, and suspensions during stages such as drug formulation, sterilization, and crystallization.

PHEs are also employed in purified water systems (such as Water-for-Injection or WFI loops), temperature control of fermentation broths and bioreactor jacket fluids, rapid cooling of product streams, efficient heat recovery, and heating cleaning (Clean-in-Place or CIP) and sterilization (Steam-in-Place or SIP) media.

The ability to maintain hygienic conditions and prevent cross-contamination is paramount, leading to the use of specialized materials and designs, such as high-grade stainless-steel plates and specific gasket types.

PHEs play a vital role in thermal management within the Energy & Utilities sector.

Their applications include cooling spent nuclear fuel elements, cooling gases and electrolytes in electrolysis plants for hydrogen production, and, crucially, heat recovery from waste streams to improve energy efficiency.

They are also used in HVAC systems for buildings, as well as in various renewable energy systems like solar thermal and geothermal.

Operational conditions in this sector often involve high pressures and temperatures, with steam and hot water loops reaching up to 150°C or more. The units must handle high flow rates and significant heat loads.

PHEs are also used in applications involving oils, requiring gaskets that can resist petroleum fluids.

Plate heat exchangers (PHEs) are indispensable in the modern Refrigeration & HVAC industry, providing efficient and reliable heat transfer across a wide range of cooling and heating applications. Whether in high-rise buildings, industrial refrigeration plants, or district energy networks, PHEs help optimize system performance, energy efficiency, and space utilization.

Their ability to handle chilled water, condenser water, hydronic heating/cooling, and complex fluid separation tasks makes them a preferred solution for contractors and engineers. In critical environments like data centers or cold storage facilities, PHEs enable precise temperature control, support rapid heat recovery, and allow for easy service and maintenance—minimizing downtime and protecting essential infrastructure.

By combining high thermal efficiency with a compact, service-friendly design, plate heat exchangers continue to set the standard for performance and flexibility in HVAC and refrigeration systems.

PHEs are extensively used in the Food, Dairy, & Beverage industry for critical heating and cooling applications that ensure product safety, quality, and shelf life.

They are fundamental in processes such as milk and cheese milk pasteurization, ultra-high temperature (UHT) sterilization, and the pasteurization of various beverages like juices and beer.

PHEs are also used for cooling milk and dairy products, in the production of yogurt, cheese, and ice cream, and in the brewing industry for wort heating and cooling.

The flexibility of PHEs to adjust capacity by adding or removing plates and their ease of disassembly for cleaning are significant advantages.

In the Water & Wastewater industry, Plate Heat Exchangers (PHEs) enhance treatment efficiency by recovering heat from treated wastewater, preheating raw water, and controlling temperatures throughout treatment stages.

Standard plates are made of stainless steel (304 or 316L), with higher grades or titanium used for harsher conditions like seawater desalination.

Gaskets must withstand chemicals such as chlorine, ozone, acids, and alkalis. EPDM is commonly used for its resistance to treatment chemicals, brine, seawater, and alkaline lye, while NBR is suitable for oily or hydrocarbon-containing water. Viton is chosen for corrosive chemicals like concentrated acids, and Neoprene for chlorinated water.

To prevent clogging, wide-gap or free-flow plate designs address fouling from solids in wastewater or sludge.
