Gas-liquid Mixed Jet Aerator

2 Hp
Gas-liquid Mixed Jet Aerator (YCL003)
The gas-liquid mixed jet aerator is a highly efficient aeration device that combines advanced gas-liquid mixed jet technology with intelligent management capabilities. This equipment effectively mixes air or oxygen with water, increasing the dissolved oxygen levels in the water body and creating a favorable environment for aquatic organisms. Furthermore, the intelligent controller precisely regulates the device, enabling automated and intelligent operation, thereby reducing the complexity and difficulty of manual operation.1.5KW jet aerator oxygenation capacity is greater than 3.0kg/h.
The gas-liquid mixed jet aerator has the following advantages in practical applications:
High efficiency oxygenation:
It uses gas-liquid mixed jet technology to quickly and efficiently dissolve air or oxygen into water, increasing the dissolved
oxygen content in the water body and meeting the oxygen needs of aquatic organisms.
Energy saving and environmental protection:
Compared with traditional aeration equipment, the gas-liquid mixed jet aerator has lower energy consumption, lower
operating costs, and reduces noise and pollution, making it more environmentally friendly.
Intelligent management:
Equipped with an intelligent controller, it can automatically adjust the aeration amount according to the water environment
parameters, realizing intelligent operation, reducing labor intensity, and improving work efficiency.
Wide range of applications:
Suitable for various water environments, including ponds, reservoirs, rivers, lakes, etc., and can be used in aquaculture,
wastewater treatment, landscape water body aeration, and other fields.
Easy maintenance:
Simple structure, easy to maintain, reducing daily maintenance workload and lowering maintenance costs.
