Features

Efficient Heat Dissipation

Can be installed under the kitchen counter without concerns about poor heat dissipation in tight spaces.

Dual Outlet Design

Dual outlet design (horizontal/vertical) adaptable to various installation space requirements.

Energy-Saving

Water has three times the heat capacity of air, reducing the energy loss from heat.

Ultra-Quite

Replacing fan designs, it significantly reduces noise levels, making it as quiet as a library.

Antibacterial

The first and only pump in the world with antibacterial properties, incorporating Ag+ silver ions, certified by SGS to effectively inhibit the growth of certain bacteria.

Power Module

Equipped with industrial-grade safety protections, it adapts to various voltage conditions to ensure consistently stable water pressure.

Thermal Overload Protection

The motor is equipped with a temperature overload protection device, effectively preventing motor damage due to overheating for reliable safety.

Double Dry-Running Protection

Features a built-in temperature protection switch and a dry-running protection device to prevent overheating caused by operation without water, ensuring safe use.

Rapid Cycling Protection

A design allows for programmable control to delay shutdown by 6 seconds, avoiding frequent pump starts and stops due to low water volume, effectively extending the pump's lifespan.

Hygiene and Durable

The impeller is made of SUS304 stainless steel to ensure water hygiene and strength.

All-In-One

Integrated system that combines the pump, motor, pressure tank, and electronic controller for a stable and enduring water supply environment for household use.
