Industrial Low Temperature EVI Air Source Heat Pump Commercial Hot Water Heater Central Water Heating System

Highly-Efficient Spiral Heat Exchanger

The spiral heat exchanger adopts highly-efficient externally threaded bronzed tubes, which increase the nucleate boiling vaporization core on the outer surface, improving heat transfer efficiency outside the tube.The internally threaded design within the tube increases the heat transfer area and creates secondary turbulence.The unique double-spiral structure ensures smooth water flow and uniform flow, minimizing ice blockage and scaling.
Perfect processing craft ensures the heat exchanger's service life.

Coaxial Tube-In-Tube Heat Exchanger

When water flows at low speeds, it creates turbulent flow within the spirally fluted tubes, making them not easy to freeze. The unique spiral fluting structure provides excellent flexibility and prevents cracking due to freezing.The spiral flow scours the fluid, providing self-decontamination, stable performance and minimal attenuation.(The larger cross-sectional area of the water-side flow channel allows for the passage of larger impurities such as silt and fibers, minimizing the likelihood of blockage.The multi-head spiral structure of the heat exchanger tubes creates turbulent flow, enhancing self-decontamination and anti-scaling capabilities, and maintaining high channel cleanliness.)Because spiral tube-in-tube heat exchangers require fewer welds during manufacturing, the process is simple and the weld quality is high, significantly reducing the risk of cracking and leaks at the joints caused by long-term vibration, pressure fluctuations and alternating hot and cold temperatures.

Imported Chip Computer Board

This facility adopts imported chips from internationally renowned brands, offering stable quality and a longer service life compared to the domestic chips used by most of factories.Because the facility operates for an average of over ten hours per day, stable performance is essential to effectively,preventing data and control point drift caused by long-term operation.It suits to different ambient temperatures, ensuring operation of the facility.Stable operation and a very low breakdown rate.

International Brand Contactors
Heat pump contactors are a constantly moving component and are used very frequently, closing and opening dozens of times daily.This is a high test on product quality.Regular contactors cannot guarantee a 15-year service life for TENESUN heat pumps.TENESUN has selected state-of-the-art AC contactors from international brands at last after repeated professional testing and comparisons, multiplying the contact current capacity by 1.5 times.It has significantly reduced repair costs, ensured the life of the facility and improved customers' satisfaction.

Multiple Protections For The Facility Ensure Safe Operation Of The System

Multiple safety protection technologies ensure safe and reliable system operation, even below -35°C, ensuring safe operation of the facility's tube system and preventing ice blockage and cracking. It has functions including water tank’s water position control, overflow protection, intelligent thermostat control, power-off memory and fault code display.

Core Product Advantage

This advanced circulating heating air source heat pump is a premier energy solution for large scale hot water projects, delivering a remarkable energy reduction of over seventy percent compared to traditional gas or electric boilers. By leveraging high performance thermal extraction technology, the unit absorbs renewable heat from the ambient air, achieving a high Coefficient of Performance that translates into significant long term cost savings for commercial operators. The specialized heating logic ensures that the system provides a stable and powerful output without the massive carbon footprint of traditional systems, making it a critical asset for modern enterprises focused on sustainability and profitability. It represents a smart investment for project contractors seeking the best balance of efficiency and reliability in a professional hot water infrastructure designed for continuous heavy duty performance.

Practical Function Design

Engineered for ultimate stability, the system utilizes a high flow and small temperature difference circulating heating strategy. By increasing the water temperature incrementally by three to five degrees Celsius per cycle, the unit significantly reduces thermal shock and mechanical stress on the compressor and heat exchangers. This gradual heating process leads to a more stable defrosting cycle and a much lower failure rate compared to traditional quick heat systems. The integrated smart control system allows for automatic start and stop based on real time water usage, ensuring a steady supply of constant temperature hot water twenty four hours a day. This precision management effectively prevents sudden water temperature fluctuations during peak usage hours, providing a seamless and high quality hot water experience for thousands of users in large buildings.
