Technology & Product Profile
Go·Well Technology for Fluid Conveying
Aiming to solve the problems of low efficiency and high energy consumption of fluid conveying systems of public buildings, municipalities and industrial and mining enterprises at present, especially industrial cooling circulating water systems, ECOWELL developed the advanced systematic optimization and energy conservation solution.
Technical concepts
Guided by the principles of the best operating conditions and most reasonable energy consumption, the company focuses on the overall system optimization from the most fundamental three elements (pipeline impedance, operating efficiency and conveyed flow) affecting the energy consumption of the water pump.

At first, using the special parameter collection standards, computer simulation and other technical means, accurately judge various causes of high energy consumption (13 categories in total) by testing and rechecking the current operating conditions of the system, and put forward the best solution of system optimization and energy consumption. Then comprehensively improve the system efficiency of energy utilization by configuration optimization means such as modification of unfavorable factors of the pipeline network, overcoming of the bottleneck of heat exchange, optimization of hydraulic balance and parameter settings and customization of high-efficiency energy-saving pumps. For systems subject to large load changes, install the variable-flow control system to realize energy conservation based on the operating conditions and further improve the operating efficiency. The company focuses on overall energy conservation for the best energy-saving effects. The Go·Well Technology for fluid conveying is also applicable to optimization and energy conservation of fan and air compressor systems.
