Eel Farming Industry Water Temperature Control Solution

Eel farming is a high value-added sector of the aquaculture industry. It has strict requirements for water temperature control. Throughout the entire growth cycle, whether it is the incubation and cultivation of eel fry or the rapid fattening and stabilization of finished eels, efficient water temperature management directly determines the success or failure of farming.

Industry Info

Water temperature control solutions for the eel farming industry, with the application of magnetic levitation variable frequency centrifugal heat pump units as follows:

temperature monitoring

The sensor continuously monitors the temperature of the aquaculture water and compares it to the set value (e.g., 26–28°C)

mode switching

Heating mode (water temperature too low): Absorbs heat from the air/water source and releases heat into the aquaculture water
Cooling mode (water temperature too high): Absorbs heat from the aquaculture water and releases heat into the environment

Precise temperature control

Magnetic levitation variable frequency technology adjusts the compressor speed in real time to match load requirements and maintain water temperature fluctuations of ≤±0.5℃

Intelligent management

Automatic protection (power cut-off, overheating, etc.), remote monitoring, energy efficiency optimization

Pain point background

The core challenge facing the eel farming industry lies in its extreme sensitivity to water quality (particularly temperature) — eels are typical ectothermic animals, and fluctuations in water temperature can directly lead to reduced feeding, metabolic di

Pain point 1

During winter, when water temperature needs to be maintained at 26-28°C, coal-fired/electric boilers have low heating efficiency (COP ≈ 0.9), consuming approximately 30 kWh of electricity to raise the temperature of 1 ton of water by 1°C. Similarly, relying on conventional refrigeration units for cooling during summer also results in significant energy consumption; More critically, traditional equipment has poor temperature control accuracy (±2°C or more), and fluctuations in water temperature can trigger stress-induced feeding cessation in eels, resulting in a 30% or more extension of the growth cycle. Additionally, sudden temperature abnormalities may cause single incidents of loss exceeding one million yuan.

Solution

Addressing the pain points of high energy consumption and large temperature fluctuations in the eel farming industry, Xinlei developed a technical upgrade plan to completely replace the original four coal-fired boilers with two Xinlei magnetic levitation heat pump units, while also installing an intelligent variable frequency control system to precisely and stably regulate water temperature fluctuations.

Superior energy efficiency: 27.7% higher than Grade 1 energy efficiency, 31.6% more energy efficient than conventional screw units, directly reducing operating costs.

Dual hot and cold supply: Efficient heating in winter and rapid cooling in summer, with a maximum water temperature of 65°C. One product meets all your water temperature control needs throughout the year (ACOP cooling efficiency of 7.92, maximum pressure ratio of 6).

Zero emissions, low noise: Active bearing control, μm-level suspension precision, no combustion pollution, suitable for modern ecological farming scenarios.
