Product Features                       

• Protection Assurance
  • The enclosure is made of SUS304 material with a P - shaped rain - proof and sun - proof design (IP55). The exterior is designed with a service life of 50 years.
• Safety and Hygiene
  • The food - grade stainless - steel flow - through body operates in a fully - enclosed manner, completely eliminating secondary pollution.
• Energy Conservation and Environmental Protection
  • Using pressure - boosting technology with water - squeezing, full - variable control, it makes full use of the pressure in the municipal water supply network, is equipped with air - squeezing pressure, and reduces pressure for small - flow, thus lowering energy consumption.
• Convenient Operation
  • One - button start and stop, with a transparent view of the working status. It is designed based on ergonomics, with a compact structure and an aesthetically pleasing exterior.
• Unattended Operation
  • Automatic pump switching, balanced operation, automatic inspection, stop when there is no water, and automatic restart when power is restored.
• Intelligent Security
  • Remote monitoring, temperature and humidity adjustment, water leakage detection, noise detection, and fault alarm.
• Quick Installation
  • Modular detachable structure, pre - fabricated in the factory and delivered as a whole. Just connect the inlet and outlet water pipes and power on to operate.
• Noise Reduction
  • Three - layer noise reduction with sound - absorbing panels, integral sound - absorbing covers, and stainless - steel exteriors, which is 10dB or more lower than conventional products.
• Reliable Service
  • The company has 16 subsidiaries, 26 branch offices, over 200 business offices, and provides 7×24 - hour after - sales service. The one - time commissioning qualification rate is ≥98%.

Application Conditions
