In the aquaculture industry, temperature control is the core key to successful aquaculture. An efficient, stable, and energy-saving heat pump equipment can provide support for aquaculture production and reduce operating costs. Shandong Nasir New Energy Co., Ltd., which has been deeply involved in the field of fishery system equipment for many years, has become the preferred brand for aquaculture heat pumps with its hardcore corporate strength, industry-leading product technology, and comprehensive service system. Why can Naxin heat pumps stand out? The answer is hidden in every strength and detail.
1、 Choosing Nasir, choosing brand heritage
Shandong Naxin New Energy Co., Ltd. was established in 2017. The company's production base is located in the Energy Conservation and Environmental Protection Industrial Park of Jining Economic Development Zone, with a standardized production workshop of 46000 square meters and a national level laboratory. As an energy-saving and environmentally friendly innovative enterprise specializing in green fishery system equipment, Naxin New Energy integrates the research and development, design, production, sales, installation, and service of temperature control systems, circular aquaculture systems, source water treatment systems, and tailwater treatment systems.
The company has a professional R&D team of more than 50 people, equipped with various production lines, laboratories, and testing equipment for fishery circular aquaculture. It has also established deep cooperation with well-known domestic research institutes and colleges, and is committed to the innovative research and development of complete sets of factory based circular aquaculture equipment, smart fishery aquaculture management systems, and IoT software, in order to promote the development of factory based smart fishery circular aquaculture equipment systems at home and abroad, and contribute to the realization of social sustainable development and the construction of a community with a shared future for mankind.
2、 Choosing Naxin, choosing the product's hard power
1. Specially designed for aquaculture, addressing three major pain points
Ordinary commercial heat pumps used in aquaculture often face difficulties in adapting to local conditions
Corrosion problem: The seawater aquaculture environment is extremely corrosive to equipment, and ordinary heat exchangers can leak after 1-2 years due to perforation.
Blockage and scaling: The aquaculture water contains many impurities, and traditional heat exchangers are prone to clogging, resulting in high cleaning and maintenance costs.
Temperature control accuracy: Seed cultivation is extremely sensitive to temperature fluctuations, and an error of ± 0.5 ℃ may indicate significant differences in survival rate.
2. Core anti-corrosion technology, specialized in combating seawater corrosion
Titanium material application, solving problems from the source
The key heat exchange components of Naxin heat pump are fully made of titanium material. A dense oxide film can form on the surface of titanium, with an electrode potential of+0.46V, making its resistance to seawater corrosion more than a hundred times higher than that of stainless steel. The heat exchange tubes are made of titanium, and the tube plates are made of titanium steel composite plates, ensuring both corrosion resistance and structural strength.
Multiple anti-corrosion measures, fearless of harsh environments
Cylinder and baffle: made of PP material, corrosion-resistant, non scaling, and wear-resistant
Base: Galvanized steel plate+spray coating dual protection, durable and long-lasting
Unit casing: using seawater specific anti-corrosion coating to increase the service life of the unit
3. Continuous spiral baffle technology improves heat transfer efficiency
The shell and tube continuous spiral baffle heat exchanger independently developed by Naxin is the core guarantee of the overall performance:
No blockage: high flow rate and no blind spots, no place for sediment to adhere
Anti scaling: High flow rate effectively reduces pipe wall scaling and extends cleaning cycle
Anti vibration: The baffle plate is continuous and integrated, and the support span of the heat exchange tube is small, ensuring stable operation
Easy to clean: segmented detachable structure, cleaning only requires removing the connecting bolts, convenient and time-saving
4. Efficient and energy-saving, with visible operating costs
The core value of a heat pump lies in "transporting" rather than "manufacturing" heat. Taking heating one ton of water as an example:
The operating cost of seawater source heat pumps is only about one-third of that of traditional electric heating
The waste heat recovery unit has higher energy efficiency and can utilize the waste heat in aquaculture wastewater to achieve cascading energy utilization
The air source heat pump can start normally at -35 ℃ and operate stably at -25 ℃, which is also suitable for cold northern regions
5. Intelligent control, worry free and effortless
Fully automatic operation: Automatically adjust the output power according to the set parameters.
Remote monitoring: equipped with RS485 communication interface, supporting centralized monitoring and remote control.
Multiple protections: high and low voltage protection, anti freezing protection, overload protection, water flow protection, ensuring equipment safety in all aspects.
6. Worry free after-sales service, quick response to solve any worries
Aquaculture equipment is most afraid of "chain failure at critical moments" - shutting down during the summer cooling peak or striking during the winter cold wave can cause irreparable losses. Naxin is well versed in this field and has established a nationwide service network and standardized after-sales system: 24-hour response: the after-sales hotline is open all year round, no matter when or where, as long as you make a phone call, technical engineers will respond immediately, and remote guidance or emergency dispatch personnel will rush to the scene.
We believe that the delivery of equipment is not the end of service, but the beginning of long-term companionship. Our after-sales team's unwavering commitment is to prioritize the protection of customer interests and ensure their peace of mind in production and breeding.
3. Product Matrix, Covering All Scenario Needs
Seawater Source Heat Pump Unit (NXR-80~800HS)
Designed specifically for seawater aquaculture, it extracts heat or cooling from seawater to achieve heating in winter and cooling in summer. With a power range of 18.7~153.2 kW and adjustable outlet temperature, it is suitable for various scenarios such as circulating heating, direct heating, and pond floor pipe heat exchange.
Air Source Heat Pump Unit (NXFR Series)
In scenarios without groundwater support, air-source heat pumps are the ideal choice. The standard model operates effectively in ambient temperatures ranging from -10°C to 28°C, while the low-temperature high-performance variant can start at -35°C and maintain stable operation at -25°C, providing reliable winter protection for northern livestock farms.
Waste heat energy recovery unit (SSHRQ series)
Utilizing the temperature difference between two media for heat transfer without the need for additional energy consumption. Suitable for scenarios such as waste heat recovery from aquaculture wastewater and industrial waste heat reuse, achieving energy recycling.
