The expansion water tank is equipped with non-toxic rubber capsules inside, which prevent contact between water and gas to ensure that the water quality is not contaminated by external factors. It is used in heating systems with deoxygenation facilities to prevent corrosion from occurring.

Good sealing performance. One inflation can be used for a long time.

It can automatically eliminate water hammer and noise in the pipeline network.

High level water tanks and towers that can replace living, firefighting, heating, and air conditioning systems are beneficial for structural seismic resistance and building aesthetics.

Small footprint, low investment, easy installation, and convenient operation and maintenance.

The system pressure can be set according to user requirements.

The constant pressure variable frequency water supply unit is a new generation of high-tech product, imprinted with the internationally popular crisis panic izbianpin speed control technology. The system adjusts the pump speed at any time according to changes in water consumption, ensuring constant pressure variable water supply and maximizing energy saving and water supply.

There are several types of variable frequency water supply units: variable frequency constant pressure variable automatic water supply units, and non negative pressure variable frequency constant pressure automatic water supply units. Fully automatic pneumatic water supply unit, etc. Design can be based on the actual situation of the user.

The performance characteristics of variable frequency water supply units mainly include: fully automatic control, energy-saving, compact equipment structure, stable water pressure, soft start of water pumps, low noise, and complete protection functions.
