Focus on customer Application Fields

Our equipment and systems produce tons of extra virgin olive oil every day. Heat exchangers play a vital role in these production lines. Their working principle is mainly based on plate or shell-and-tube configurations, allowing high-temperature heating media (such as steam) and low-temperature crude oil to exchange heat without direct contact. They are widely used in key processes such as crude oil preheating, high-temperature heating in deodorizing towers, and cooling crystallization. For instance, during the deodorization stage, high-temperature steam or thermal oil rapidly heats the oil above 220°C to remove odors; in the cooling phase, chilled water or refrigerant quickly lowers the oil temperature to prevent oxidation and promote wax crystallization. This ensures precise temperature control during oil processing, maintaining stable product quality and flavor.

Many ships worldwide are equipped with our products and solutions. Among them, heat exchangers serve as core components in ship power systems, central cooling systems, and fuel heating systems. Their fundamental principle involves isolating heat exchange between seawater and internal working media (such as fresh water, lubricating oil, or fuel oil) through metal walls. For example, in central cooling systems, cold seawater absorbs heat from the freshwater loop, which itself has absorbed heat from equipment such as main and auxiliary engines, enabling efficient heat dissipation. In fuel heating systems, steam or high-temperature hot water is used to heat high-viscosity heavy oil to the optimal atomization temperature range. This ensures the efficient and stable operation of ship power systems in complex marine environments.

We maintain a critical balance between flavor preservation, food safety, and production efficiency. Our equipment handles millions of liters of wine and beer annually. Heat exchangers (primarily plate types) in the beverage industry operate on the principles of rapid, hygienic, and efficient heat transfer. During pasteurization, the product and hot water/steam quickly exchange heat through thin plates to reach approximately 72°C and maintain this temperature for a specific duration to eliminate harmful microorganisms. This is immediately followed by rapid cooling ("flash cooling") via chilled water or refrigerant to preserve flavor as much as possible. Similarly, temperature control in fermentation tanks relies on heat exchangers to precisely remove the biological heat generated during fermentation. This efficient heat recovery and precise control are key to achieving balance.

CHINA PHE possesses unique expertise in the increasingly critical fields of effluent treatment and recycling. The application of heat exchangers in this area centers on recovering waste heat or cooling energy from wastewater or providing precise temperature conditions for specific biological/chemical treatment processes. For instance, in anaerobic digestion for biogas production, plate or tubular heat exchangers utilize the high-temperature biogas produced or waste heat from engines to heat incoming sludge, maintaining it at the optimal methane-producing temperature of 35–38°C (mesophilic digestion). This significantly improves treatment efficiency and biogas yield. In sludge thermal drying or advanced oxidation processes, heat exchangers are used for media heating and energy recycling.

CHINA PHE is involved throughout the entire process, from raw material extraction to energy production and utilization. Heat exchangers are widely used in the energy sector. Their fundamental principle is to transfer, recover, and upgrade thermal energy between different fluids. In oil and gas extraction, heat exchangers provide heating for high-pour-point crude oil. In refineries, large shell-and-tube heat exchangers enable "heat integration" among complex process streams, using the heat from high-temperature effluents to preheat low-temperature feedstocks, significantly reducing overall energy consumption. In power plants, condensers transfer heat from turbine exhaust steam to circulating cooling water, completing a key step in the Rankine cycle. In geothermal or waste-heat power generation, heat exchangers are the core equipment for transferring low-grade thermal energy to working fluids.

Our equipment and solutions are critical for executing and optimizing numerous industrial processes. As a universal key component in process industries, the application principle of heat exchangers lies in meeting the strict temperature curve requirements of chemical reactions, physical separations (such as distillation, evaporation, and crystallization), and other processes. By precisely controlling the preheating temperature of reactants, the rate of exothermic reaction heat removal, the heating load of distillation column reboilers, and the condensing temperature of overhead vapors, heat exchangers directly determine reaction rates, product yields, purity, and system energy consumption. Their design and selection are closely aligned with the thermodynamic and kinetic needs of specific processes.

A significant portion of the starch produced worldwide annually comes from our products and processes. The application of heat exchangers in starch processing primarily relies on the efficient and uniform heating or cooling of slurries containing solid particles. During starch slurry preparation and liquefaction, specialized plate or tubular heat exchangers enable instantaneous mixing of starch slurry with steam and rapid heating above 105°C, promoting starch gelatinization and enzymatic hydrolysis. This process requires extremely fast heat transfer to prevent starch retrogradation. In subsequent saccharification and evaporation/concentration stages, heat exchangers are used to maintain constant-temperature enzymatic hydrolysis and efficiently remove water. Their design must account for changes in material viscosity and anti-fouling considerations.

We offer a wide range of products to meet the industry's exceptional demands for precision, safety, and cleanliness. The application of heat exchangers in this field is based not only on precise temperature control but also on "sterile" and "validatable" design principles. They are constructed from fully stainless steel materials with mirror polishing and dead-space-free connections (e.g., double plates, sanitary shell-and-tube) to ensure complete cleanability and sterilizability (CIP/SIP). During fermentation, they precisely remove metabolic heat via jackets or internal coils to maintain optimal cell growth temperatures. In purified water systems, they heat or cool water to inhibit microbial growth. In freeze dryers, they provide precise cooling and heating for shelves to control product sublimation and desorption processes. All heat transfer surfaces comply with FDA and GMP standards.

CHINA PHE is a leader in climate control, providing optimized heating and cooling balance solutions. Heat exchangers (often referred to as "coils" or "cold/heat exchange cores" in this field) are central to HVAC and refrigeration systems. Their working principle involves utilizing refrigerant evaporation to absorb heat or condensation to release heat, or facilitating heat exchange between water/glycol solutions and air. In chillers, evaporators absorb heat from chilled water, while condensers release heat to cooling water or air. In fan coil units, chilled water flows through coils to cool the air. In energy recovery ventilators, specialized membrane cross-flow channels simultaneously recover sensible and latent heat from exhaust air. These applications focus on efficient, low-noise energy transfer.

Our equipment helps the food industry transform high-quality raw materials into equally high-quality products. The application of heat exchangers in food processing integrates principles from thermodynamics, fluid mechanics, and food engineering, aiming to achieve rapid and uniform thermal treatment for sterilization, cooking, altering physical properties, or preserving quality. For example, in dairy UHT sterilization, plate heat exchangers heat milk to above 135°C within seconds and then immediately cool it, minimizing the loss of heat-sensitive nutrients. In chocolate tempering, precisely controlled heat exchange surfaces guide cocoa butter crystallization through specific temperature curves to form stable crystal structures, resulting in a glossy appearance and crisp texture. The entire process strictly controls temperature and time, ensuring both safety and quality.
