Commercial Distillation Equipment
Distillers utilize technology that replicates the hydrologic cycle found in nature: evaporation, condensation, and precipitation.

Excel water in collaboration with Norland International offers two different types of water distillation systems: Vapor Compression and Multiple Effect systems. Production capacities of these systems range from 500 gallons (1,900 L) a day up to 6,000 gallons (22,712 L) per day of high-quality distilled water (less than 2ppm TDS).

Commercial Vapor Compression Distillation Systems
Vapor compression distillation systems produce high-quality distilled water and offer maximum profitability through optimum efficiency. There are four vapor compression distillation systems for commercial uses such as water purification for the bottled water industry.

The vapor compression systems produce 1500 gallons (5700 liters) 3,000 gallons (11,340 liters) or 6,000 gallons (22,712 liters) per day and are extremely energy efficient. The high-quality, distilled water has less than 1 ppm TDS.

Vapor Compression Technology
The boiling process begins with both heating elements turned on. The compressor turns on when the water is near boiling point, which engages the unique non-contacted liquid ring seal. When the boiling point is reached the #2 heating element turns off and the #1 heating element cycles on and off maintaining the boiling point at just the right temperature for maximum efficiency. The steam from the boiling water flows through a baffling system and then into the compressor.

In the compressor the steam is pressurized, which raises the temperature before it is routed through a special heat exchanger. The pressurized steam gives off its heat to the feedwater inside the boiling chamber causing this water to boil, which creates more steam.

While the pressurized steam is giving off its latent heat, the steam will condense. One of the heating elements will cycle on and off periodically as needed to provide any “make-up” heat that is required to keep the system operating at optimum temperature for maximum efficiency.

At this stage the condensed steam is considered distilled water but is still very hot. The hot distilled water preheats the incoming feedwater that will be distilled.

As the incoming water is preheated, the outgoing distilled water is cooled. The systems are designed to cool the distilled water to within approximately 20 ° F (11 ° C) of the incoming feedwater temperature. This allows the feedwater to be preheated to within a few degrees of the boiling temperature, saving further energy. In fact, the VC3000, VC1500 and VC800 recycle nearly 98% of energy required.

The VC systems offer heat exchangers exchangers that can be cleaned in the event manual cleaning is ever required. Since feedwater is boiled on the inside of the heat exchanger surfaces, access to the portions of the heat exchanger that may require cleaning is much easier.

Features:
• Easy installation
• Solid-state operational controls
• Minimal preventive maintenance
• Dependability and durability
• Low operational costs. (Electricity will cost less than $0.01/gallon)
• Up to 98% less waste water used than with other models
• Up to 6,000 gallons (22,712 liters) per day
