High Efficiency EVI Air Source Heat Pump Low Temperature Circulating Heating Hot Water System for Cold Area

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.
