GALLON PER DAY VAPOR COMPRESSION(VC) STEAM DISTILLATION SYSTEM SHOWN
AT RIGHT.
(Sorry
guys, the lab technician is not included with the system)
Step
1: In a vapor compression(VC) system, the distillation process
begins in the boiling chamber, just as it does in virtually any other
distiller. What separates this method from other distillation methods
is what comes after the boiling chamber.
Step
2: In a Vapor Compression VC6000, VC3000, VC1500 and VC800 system
the boiling process begins with both heating elements turned on. As
the water in the boiling chamber reaches near boiling temperatures,
the compressor turns on, which engages the unique non-contacted liquid
ring seal.
When the boiling
begins, the #2 heating element turns off and the #1 heating element
cycles on and off maintaining the boiling at just the right temperature
for maximum efficiency. The steam from the boiling water flows through
a baffling system and then into the compressor.
Step
3: In the compressor, the steam is pressurized, which raises
the steam's temperature before it is routed through a special heat exchanger
located inside the boiling chamber. The steam (under pressure) is at
a higher temperature than the feed water inside the boiling chamber.
Step
4: The pressurized steam gives off its heat to the tap water
inside the boiling chamber, causing this water to boil, which creates
more steam. In technical terms, the steam "gives up its latent
heat of vaporization" to the water inside the boiling chamber.
Step
5: While the pressurized steam is giving up 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.
Step
6: At this stage, the condensed steam is considered distilled
water but is still very hot--only slightly cooler than boiling temperature.
To get maximum efficiency from the VC systems, the hot distilled water
preheats the incoming feed water that will be distilled.
AMAZING
EFFICIENCY!
Step
7: As the incoming water is preheated, the outgoing distilled
water is cooled. The VC3000, VC1500 and V800 systems are designed to
cool the distilled water to within 20 degrees F of the incoming water
temperature. The remarkable VC6000 cools the distilled water to within
4 degrees F. of the incoming water.
This remarkable
design of the VC6000 allows production of high quality distilled water
at less than 0.085 Kwh/US gallon. Conversely, this allows the feed water
to be preheated to within a few degrees of the boiling temperature,
saving further energy. In fact, the VC6000, VC3000, VC1500 and VC800
recycle nearly 98% of energy required.
Step
8: The VC systems offer heat exchangers that can be cleaned in
the event manual cleaning is ever required. Since feed water 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.
COST
EFFECTIVENESS OF
VAPOR
COMPRESSION WATER DISTILLATION SYSTEMS
Vapor compression
processes produce water 5 to 10 times more cost effectively
than multiple effect distillers(see
below) and 25-40 times more cost effectively
than conventional, single-stage distillers.
In real dollars
and cents, at 10 cents per kilowatt hour, this translates into less
than 1/2¢ per gallon for vapor compression
versus 7-8 cents per gallon for a multiple-effect distiller and 30-35
cents per gallon for a conventional, single-stage, home-use steam distillation
system.
When one considers
these cost savings in a bottling operation, the clear advantages of
vapor compression systems(volume of water and production cost per gallon)
become very clear as shown on the diagram above.
The
payback period for a typical 1500 gallon per day vapor compression distiller,
operating at full output(say 5000, 1-liter bottles per day), selling
at 60 cents per liter(wholesale) is less than 17 operating days. This
is truly a remarkable payback.
For
a water store selling 1500 gallons of distilled water daily(and there
are a number of them doing just that) at 50 cents per gallon, the payback
period is less than three months!
SOME
THINGS YOU WILL REALLY LIKE ABOUT THE VC-800, VC-1500, VC-3000 and VC-6000
DISTILLATION SYSTEMS.
1. Electronic
control panel is easily accessed for servicing. One solid-state circuit
board controls operation of the complete system.
Incredibly easy, "one look" operations check for pressure,
system water purity, heating system operation and operating set points. 
2. Submerged
tube-in-shell heat exchanger provides efficient and uniform heat transfer.
The end plates are removable for one-step access to the heat transfer
bundles if necessary. The end plates include pyrex sight glasses for
easy monitoring of heat exchanger cleanliness. Superior to any other
distillation system we have used over the last 20 years.
3. Removable
exterior panels allow full access to internal components for quick,
easy servicing.
4. Continuous flow evaporator produces
very high quality distilled water at maximum efficiency.
Cooling water exits at room temperature, thus ensuring maximum heat
transfer to distillation process.
5. Feed water/distillate
heat exchanger preheats the feed water, cools the distilled water for
maximum operational efficiency. Tube-in-shell design provides excellent
heat transfer while being very easy to service.
6. Titanium
compressor rotor provides the strength required for a long, durable,
trouble-free life, while being extremely light.
Other commercial distillers we have
used constantly experienced problems with seals and the integrity of
titanium blades on compressor.
These units
have demonstrated (to us) far superior mechanical integrity and ease
of replacement.
7. Compressor
bearings are the self-aligning pillow type, for long life and easy maintenance
and replacement. These are components which need to be replaced periodically.
However, the use of 1-1/4" diameter shafts and bearings permits
extraordinary stability for the compressor(see 6. above) as well as
longer life for individual bearings.
Clearly superior
to any other equipment we have seen or used in the last 20 years which
uses vapor compression technology and external drive shaft mechanisms
as shown to the right.

Most
competing water purification systems can use up to eight gallons
of reject water for every gallon of water they distill. The
VC6000 distiller produces nearly six gallons of distilled water
for every one gallon of reject water.

if you can find a commercial reverse osmosis system that is
this water efficient!
