In sectors where water purity is critical—such as laboratory analysis, medical preparation, and precision manufacturing—distillation remains one of the most effective and scientifically trusted methods of water purification. Unlike basic filtration, distillation physically separates contaminants by leveraging phase change, ensuring the removal of dissolved solids, heavy metals, and microbial impurities.
A water distiller is a purification device that removes impurities by boiling water and then condensing the steam back into liquid form. This process separates clean water from dissolved solids, salts, microbes, and other contaminants. Compared to other filtration methods such as reverse osmosis or activated carbon filters, distillation offers a highly thorough level of purification, making it ideal for medical, laboratory, and industrial use.
Every water distiller functions based on a fundamental process supported by several essential components. The boiling chamber heats raw water to its boiling point, initiating vaporization. The resulting steam then passes through the condenser coil, where it is cooled and converted back into liquid. This purified water is collected in the collection container. In advanced models, auto-control and safety features such as self-break and auto-shutoff systems are included to prevent overheating and ensure operational safety.
To fully appreciate how a water distiller purifies water, it’s helpful to understand each stage of the distillation process. From initial filling to final collection, the system operates through a series of controlled steps that ensure maximum purity and safety. Below is a step-by-step breakdown of how a typical water distiller functions:
Filling the Boiling Chamber: Raw water is introduced into the chamber, preparing it for the distillation process.
Heating the Water: The electric heating element raises the water temperature to its boiling point (100°C), converting it into steam.
Separation of Contaminants: As the water evaporates, dissolved solids, microorganisms, and other non-volatile substances are left behind in the chamber.
Steam Transfer: The generated steam is directed through cooling coils or a condenser, where it undergoes controlled cooling.
Condensation: The cooled steam condenses back into purified water, free from contaminants.
Collection: The distilled water is collected in a separate container, ready for use or further processing.
Auto Shut-Off: In advanced models like the WD-SS Series, a self-break function automatically shuts down the system when the water supply is depleted or the distillation cycle is complete, preventing overheating and protecting the equipment from dry burning.
We proudly offer the WD-SS Series — an advanced line of water distillers designed for safety, efficiency, and continuous operation:

| WD-SS10A | 380 | 7.5 | 10 | 10.5 |
| WD-SS20A | 380 | 15.0 | 20 | 13.5 |
The system offers several key advantages that enhance both performance and usability. Its automatic control ensures consistent and reliable operation, while the self-break protection feature improves safety and extends the lifespan of the equipment. Constructed from stainless steel, the unit is resistant to corrosion and easy to clean. In addition, its compact design makes it an ideal choice for use in clinics, laboratories, hospitals, and small-scale industrial settings.
To maintain optimal performance, the water distiller should be operated and cared for properly. Regular cleaning of the boiling chamber is essential to prevent scale buildup. It is also important to use suitable feed water, avoiding sources with excessive contamination. Periodic inspection of electrical components and auto-shutoff mechanisms helps ensure safe operation.
Understanding how a water distiller works provides valuable insight into why it’s a preferred solution in various high-purity applications. The WD-SS Series Self-Break Auto-Control Water Distillers offer a powerful combination of performance, safety, and convenience—making them a reliable choice for laboratories, medical institutions, and light industrial use.
