Tubes in shell heat exchangercan enlarge the heat transfer area by changing the length of inner spiral tube. Water and refrigerant flow around the inner spiral tube in reverse direction. After refrigerant cooling and liquefaction condensation, the surface tension of liquid film in the tube reduces the heat transfer resistance and improves the heat transfer efficiency.
Wate to water/ air to water heat exhcanger with high heat transferring efficient heat exchanger tubes and smooth shell, it ensures high velocities inside of the unit making the heat exchanger a very reliable, efficient and cost effective way to transfer heat indirectly between any boiler/solar water heater or heat pump water heater circuit and any pool or spa circuit, besides other applications.
Product Description
Structure Feature
High efficiency
Spiral groove structure can enhance heat transfer on both sides. The axial flow and spiral rotation flow of the fluid in the tube will intensify the mixing of the fluid near the tube wall, thus enhancing the turbulence intensity and increasing the heat transfer coefficient
Self-cleaning ability
Self-cleaning ability because the fluid spiral flow washes the surface. this heat exchanger has stable performance and low attenuation. The cross-section area of the waterway is large, allowing sediment and large diameter fibers to pass through without blocking. The water passage is clean because the inner tube of the spiral groove keeps the flow turbulent and cleans the surface
Effective prevention of freezing
Water is not easy to freeze because it is turbulent when it flows at a low speed in a spiral groove. The special spiral groove structure of the inner tube makes the inner tube flexible to a certain extent and does not produce the risk of frost cracking.
Less risk of leakage
Heat exchangers are very worried about leakage due to long-term vibration, pressure fluctuation, alternation of heat and cold, and so on. The risk of leakage of coaxial exchangers is seldom due to fewer welding points, simple processing and easy control of welding quality
Adapt to all kinds working conditions
In the actual operation of refrigeration system, the internal pressure is often in an alternate state due to temperature fluctuation, start-stop cycle, heat pump defrosting, expansion valve regulation and other factors. Spiral coaxial heat exchanger is more resistant to pressure shock and pressure shock than plate heat exchanger under constant vibration and pressure change, and can adapt to the complexity of actual working conditions
Coaxial tube heat exchanger inner tube can be made of different materials such as high quality copper, 316L, 304 stainless steel, nickel copper, titanium tube and so on.

Company Information
APT’s story
APT, Foshan Applied Process Technologies. We focus on two technologies application: thermal spraying and heat exchanger.
Our heat exchanger plant was set up in 2008, and soon encountered the well-known financial crisis, the economic environment suddenly deteriorated, and we immediately faced the problem of survival. Lowering quality and service standards has become the last trump card of many peers, but this goes against our original intention. We adhere to quality and service. For this reason, we have paid a price. A number of customers have lost, and some shareholders have withdrawn their capital, resulting in an unprecedented financial crisis. But we also got a surprise: after a few months, our lost customers came back with new products and cooperation. These customers are now our most loyal partners.
Over the past 10 years, whether it is to open up the market or to improve the satisfaction of the original customers, we rely on: Never say YES to poor quality and service.
APT's thermal spraying team began to study thermal spraying application technology in 2010. Fortunately, the company currently has a very professional thermal spraying technology team. Especially in aviation and paper machinery applications, we have been providing very professional products and services to domestic customers. Now, APT is the specialist applicator of thermal spraying, we produce a variety of thermal spraying coating, including HVOF, plasma, Arc, D-gun coating, we can provide coating detection and evaluation services, we can provide training services for coating research and development, we provide thermal spraying equipment design, thermal spraying production consumables. I believe that the company's strong technical background, will be able to meet customer demand for thermal spraying process.
Because of our reliable quality and 24-hour service support, we are particularly favored by exporters. According to incomplete statistics, 70% of our current business is exported overseas through traders. With the increase of business, quality management and service problems become more and more prominent. As we all know, TRADERS’ service to overseas customers is microphone-like. In many cases, it cannot solve customers' problems in a timely and professional manner. Overseas customers also cannot have the most favorable price and professional service provided by us as manufacturers. You know “focus on satisfying customers’ needs” is our company's way of survival. In order to enable global customers to have our more professional and direct products and services, we have carried out a series of restructuring and adjustment, which is now APT company.
