__________________________________________________________________________________________ 12. August 2010 LARGE BACKUP SOLUTIONS
What is a solar home system
like described below without solar panels and without solar
charger? It is a smart setup for "uninterrupted power
supply" - an UPS. Our Victron Multiplus devices are not
only battery charger and inverter but on top of this they
act as a very fast transfer system: In case of a power cut,
they switch in not more than 40 mS to the battery backup.
So if you need an uninterrupted power supply for your office
or for your residence - regardless 1-phase or 3-phases power
- our large UPS-solutions are an economical choice and -while
maintenance free- a real alternative to diesel generators
powered backup. Click on the thumbs to enlarge:
__________________________________________________________________________________________ 11. August 2010 SOLAR HOME SYSTEM
We have installed the first
solar home system in Koh Samui. It will supply the energy
for a 2 bedroom house with swimming pool. The whole project
costs were less than the fees to get a connection to the public
grid. For remote areas these kind of solar systems are an
economical option - but be aware that it is still not possible
to supply air conditioners. Beside of that it is a must to
invest in low energy devices for lighting and for pumping.

__________________________________________________________________________________________ 26. July 2010 COST SAVING FOR THE "FOUR SEASONS"
The Four Seasons in Chiang Mai
has a large laundry section with a hot water consumption of
approximatly 5 cbm per day. To reduce the running cost for
the gas fired boilers Samui Service has installed a waste
heat recovery for the very large air conditioner. The hot
water is stored in two 500 l pressurized tanks. We estimate
that this system will provide around 2,500 kWh cost free thermal
energy per month which is equivalent to 250 kg gas. Click

Samui Service has delivered
mobile solar pumps with solar panels for a governmental project.
The pumps and the solar panels will be used to irrigate farmland
in the Northeast of Thailand by pumping surface water. Both
solar panels and the pump from Lorentz Germany can be transported
by truck to where the water is needed. Click the thumbs too

__________________________________________________________________________________________ 26. June 2010 WIND ENERGY ON KOH SAMUI
Samui Service has installed
the first wind turbine on Koh Samui. The Whisper 200 is standing
on top of the Samui mountains at an altitude of 621 meters.
Thailand is not at all a "wind country" but we are
pretty sure that this is by far the best location on Koh Samui
for a wind turbine. Together with a small solar array the
Whisper 200 will provide enough energy to supply one restaurant
and to illuminate a buddhist temple on top of Koh Samui. It
should be mentionned that already this rather small wind turbine
must be erected at least 20 meters away from the nearest building
- noise is really an issue. Hence we have installed controller,
batteries and AC inverter into an adjointed building with
small AC wires going to the supply points.
This project together with the new temple is donated by Khun
Voravuto, a Thai citizen and Bangkok resident. We say thank
you.
Please click

__________________________________________________________________________________________ 21. April 2010 LOW ENERGY POOL PUMP - HOW IT WORKS
Swimming pool pumps are consumpting
10-20 % of the total energy need of a standard Villa in Thailand.
This is not necessary. To reduce the energy consumption just
install a smarter pool pump.
Now look here, this american pool technician is explaining
"how it works":
We are promoting
this "Pentair
IntelliFlo Pool Pump", because
> it saves a lot of energy and money
> it has a more effiicent motor than the standard pumps
> it offers many features like built-in controller, LCD
display, spa functions, backwash alarm etc.
> there are so many swimming pools in Thailand!
Europeans are not used to "gallones
per minute" "GPM" and "pound per square
inch" "PSI". We like "cbm per hour"
(cbm/h) and "bar" :
> 1 Gallone = 3,79 liter. Hence 80 GPM = 18,2 cbm/h.
For a medium size pool with 80 cbm volume it is enough to
run a pump with 80 GPM for 8 hours a day
> 13 PSI = 0,9 bar or 9 meters water column
Last but not least: The enery price in USA is 100 % higher
than in Thailand.
The physics behind are rather
easy (this is now a bit simplified, we not consider the static
head...):
Friction losses in a piping system are proportional to the
square of the velocity of the pumped water. While velocity
is proportional to the discharge of the pump: If dischage
is bisected (like from 80 GPM to 40 GPM) then the friction
losses are reduced to 25 %, the pump needs only 25 % of the
energy and not 50 %. In other words:
> A pump that can discharge
80 GPM at 2 kW will need only 1,1 kW to discharge 60 GPM
> A pump that can discharge 80 GPM at 2 kW will need only
500 W to discharge 40 GPM
The Pentair IntelliFlo uses even only 290 W because the motor
is more efficient at lower speed.
What does this mean for your
electricity costs per year (EC):
Standard pump 2 kW, 80 GPM, 8 hours per day:
EC = 365 days/year x 2 kW x 3 THB/kWh x 8 hours/day = 17,520
THB per year
Pentair IntelliFlo pump maximum 3 HP, running at 290 W, 40
GPM, 16 hours per day:
EC = 365 days/year x 0,29 kW x 3 THB/kWh x 16 hours/day =
5,081 THB per year
Savings are 12,500 THB per year
which allows a pay back after 1-2 years (compared to standard
pool pump).
Regarding the CO2 emission the energy saving of 4,000 kWh
equals more then 3,000 kg CO2 gas emission.
Be smart, be green and
save money!
__________________________________________________________________________________________ 02. April 2010 DRINKING WATER MADE BY GERMAN TECHNOLOGY
We are now dealer
for PURION
GERMANY water disinfection systems. This will allow us
to "sell drinking water"!
Purion uses UV radiation to destroy the DNA of bacterias.
This technology is a lot cheaper than Reverse Osmose and it
is 100 % chlorine free.
UV radiation is applied worldwide to supply drinking water,
regardless if the source is well water or lake water. As it
is a low energy technique we can supply the systems with solar
energy.
If you have problems
with the water quality, contact us, we can provide drinking
water at every tab of your house.
Click here
to understand the operating principle and here
for specifications of the purifiers.
Of course we
also provide tank ozonisation and filter stations. And we
consult before we sell!
__________________________________________________________________________________________ 09 March 2010 3-PHASE SOLAR POWERED SUBMERSIBLE PUMP
Now solar pumping
is available even for very large water demands up to 500 cbm
per day: Lorentz Germany has developped new solar powered
3-phase submersible pumps with 10 or 15 HP. Click here
for specification.
The PS9k is connected to 9 kWp
solar array while the more powerful PS15k needs 15 kWp to
operate at maximum power. For non-tracked operation we advise
to install 12 kWp / 20 kWp solar array.
The pump controller offers a lot new features like
> two control inputs for well probe (dry running protection),
float or pressure switches, remote control etc.
> automatic reset 20 minutes after well probe turns pump
off
> data logger for historical dates: running time, starting/shut
down time, max. power/voltage, accumulated energy etc.
> display of current running data such as: input/output
current/power/voltage, pump speed, temperature
> speed control selectable, max. and min. speed
> solar operation: integrated MPPT (Maximum Power Point
Tracking)
__________________________________________________________________________________________ 28. February 2010 LOW ENERGY LIGHTING SOLUTIONS
No 50W halogen
spot lights! No 100W incandescent bulb!
We it comes to interior lighting LED are already the best
solution. With RGB LED you can choose and change between many
different colours and many nice features including dimming
and fading. LED are the most elegant way to create an interesting
atmosphere! Power consumption is only 5 W per meter. We have
combined these LED with very bright CFL bulbs 15 W, dimmable
as well. Click on the thumbs to enlarge!
"LED are expensive!"
No, the whole lighting costs for this project were only 1
% of the total budget.

14. December 2009 AIR CONDITIONERS AND HOT WATER
The first installation
jobs with Air conditioning and Hot Water have been completed
succesfully:
For these newly renovated bungalows we
have installed the hot water tanks where the water is getting
heated directly by the refrigerant pipe. We use stainless
steel tanks and heat exchangers, no risk of corrosion - these
systems are running fine since ten years!
Retroffiting of the waste heat recovery system:
The heat exchanger is behind the compressor, the warm water
is transfered to the tank by PPR pipes. Besides of the storage
tank this system needs a circulation pump and magnetic relays:
____________________________________________________________________________________
31. October 2009 TESTING WASTE HEAT RECOVERY
Our new branch is getting cooled by an
24,000 BTU air conditioner with waste heat recovery:
The thermal heat in the refrigerant gas - normally blown out
by the compressor fan - is transfered to a water filled circulation
pipe which is connected to a hot water storage tank. For several
days we have monitored both the energy consumption of the
A/C and the hot water generation:
- It takes 6 hours to heat up 300 liters
water from 31°C to 45°C, this is enough for 10 warm
showers and it is equal to 5 kWh
- In average the A/C is consumpting 1,6 kW per hour, hence
almost 10 kWh in these 6 hours
- This means that 50 % of the electrical energy to run the
A/C is normally wasted - blown in the air by the compressor
fan.
- The yearly costs saving by running 6 hours is more than
6,000 THB - not regarding the saved investment for several
electric water heaters.
Regarding your electricity bill:
The standard hotel business is charged also according to the
maximum demand in 15 minutes, see here,
page 6.
This "demand charge" means for example:
- For 10 electric heaters each 5 kW running at the same time
for 15 minutes the "demand charge" on your bill
will be 10,000 THB per month higher! Avoid electric heaters
but use your air conditioner to provide hot water.
Be smart, be green and save money!

18. July 2009 THE LARGEST PRIVATE SOLAR INSTALLATION
IN THAILAND
After coordinating three specialised teams
and up to 12 staff members, after installing 250 m² of
solar panels,
8 tons of batteries and more than 2 km of cables:
The largest private solar installation in Thailand is providing
80 kWh of 3-phase energy and 20 m³ of fresh water per
day.
Beside of this we have supervised the whole water feder system,
assisted to establish a smart irrigation system and finally
low energy intelligent pool pumps and a modern water purification
system.
Everything is working fine but of course they are still some
problems or concerns about the established new technologies,
hence we now focus to the "after sale service",
means we are still on site every week for training (and learning!)
purposes
and to check which parts of the systems might better be upgrated.
A very exciting project is becoming succesfull and it will
be our showroom for similar scopes.
Here some impressions, please click the pics to enlarge.
The
project has the size of an hotel with different buildings
Located
on the beach without road access!
Coordination
is a basic duty
but not easy in Thailand.
Voilà
126 solar panels
Rough
conditions close to the sea - hot and dangerous
The
SMA inverters are creating a pure 3-phases AC grid.
Six Sunny Islands on the way to their destination.
We control the performance by the grey colored webbox.
We have designed and installed some very special features.
Setup
of 8 tons of batteries providing..
...
total 200 kWh energy. Enough for 3 days supply.
The
small diesel backup will start automaticly on very high
load.
The
solar tracker is supplying 4 DC solar pumps
Installation
jobs can be wet and funny.
We
will now monitor the water supply and demand - to learn
more.
The 250 m³ pool would normally use of 60 kWh pump
energy
Our
smart pumps can reduce this to only 20 kWh per day!
Where
to buy or order the specific device? Difficult every
day!
Drinking water by an UV lamp with filtration
Low energy solar fridge and freezer - saving up to 70
%
My
teams: Keen to learn, carefully and always in good mood!
This high-end Villa will be promoted
all over Asia as a top holiday residence with a focus
on "eco friendly" - not in a "hippy sense"
but in merging renewable energy with smart low energy
devices. The gain in marketing branding and originality
of this destination will be huge. Depending on the occupancy
rate we estimate to cover 80-90 % of the energy need by
solar power. Please contact for more info or for a visit
on site.

03. March 2009 REVERSE OSMOSIS SYSTEM
Together with our close partner
Ourworld Ltd. from Vientiane/Laos we now offer RO systems
for water desalination.
Where no grid is available our small DC systems (starting
at 32 liter per hour) can run on solar power.
For a large need of potable water we have AC systems able
to desalinate up to 30 cbm per day.
Please contact for more info and a pricelist.

20. February 2009 AIR-TO-WATER HEAT PUMP WATER HEATER
This is definetly an cost
effective alternative to solar water heaters,
especially if the property will not be occupied every day
of the year.
Low energy consumption and the cooling capacity makes it a
"green product".
____________________________________________________________________________________
10. February 2009 SOLAR LAUNDRY HEATER
Twelve
heat pipe collectors and one 1000 liters Solar tank
will help the Anantara Golden Triangle to reduce the
extremly high gas costs at the laundry section.
Definetly a useful application for Solar because the
thermal energy is produced "on demand" means
from 8 am to 5 pm when the large laundry machines are
running.
Considering that the Anatara is located some 1,600 km
away from Samui and that we had to ship a lot of equipment
for this large installation we are pretty proud that
we could complete this demanding job in a succesfull
way. Thanks to the Anantara team for their support!
