Yearly still 1 million people day from mosquito bites... On the Thai islands like Koh Phangan mosquitos can be a plague and a source of irritation. But during the year, they can also cause Dengue fever which needs hospitalization so mosquito control is in place!

What makes this mosquito trap such an effective killer? This is THE most powerful mosquito attractant. The machine emits a steady flow of carbon dioxide, heat and moisture that mimics human emissions, lures the mosquitoes into the mosquito vacuum. The pests become caught in the mosquito vacuum's mosquito net, where they die from dehydration within 24 hours.

The 24/7 automatic operation means the mosquito trap acts as a continuous mosquito defense machine throughout the mosquito season. By disrupting the breeding cycle of flying pests, our mosquito fogging machine will provide a dramatic reduction of the mosquito population — protection that lasts all season long.

How long does it take to be effective?

From the moment that the mosquito trap is installed it is effective. To see a huge drastic significant result, it is necessary to break the breeding cycle which is 4 weeks.

Which area can be covered?

A machine covers an area as large as 3000 SQM.

How to set up?

The best spot is to set up the trap between the breeding area and the human living area. A distance of 12 meter from the living space is strongly recommended!

What is the maintenance?

The system can plugged in to the grid toget energy. About once a month the gas tank needs to be replaced. Secondary, a mosquito attracting liquid 1-Octen-3-ol is added on monthly base. 


We guarantee a splendid result after a period of maximum 4 weeks. Not satisfied? Your money is returned!

One of the most greatful energy resources in Thailand is the sun...Thailand has 1 of the highest sun irradiation factor in the world. We focus on 2 major technologies which are photovoltaic power and CSP systems.

Concentrated Solar Panels - Put trough system


A CSP can be a parabolic shape or a dish shape. The concentration of the sun is 15 to 80 times. 

The biggest disadvantage of all these systems is that you need the sun so rainy days and the night cause a discontinu system where storage becomes very important...

However, this system has a lot of advantages as well. The biggest and most important is the costprice. The elements can be made cheap which gives an interesting ROI.

The maintenance of the system is low due to the simplicity of the construction.



The sunradiation is concentrated through a long parabolic mirror in the focus of the mirror. In this point, a stainless steel tube is placed and water is run through the pipe. 1 liter water will evaporate and thus expand to 1600 liter vapor with a temperature between 150 and 400 degrees Celcius (depending on the construction and the sun radiation). 

To avoid heat leaking of the tube, an extra transparant tube insulates the steam pipe. 

The steam is used to feed a steam turbine and finally to alternate a generator creating electrical power.  

Photovoltaic Solar Panels 

PV Solar

PV panels is a trusted technic to generate electricity. The efficiency of the panels is nowadays around 20% and the lifetime is more than 25 years while keeping 80% of the initial output!

The advantage of PV solar is that a system can be well dimensioned and if needed expanded however with some restrictions...

There are 3 systems: off grid: with no connection to the grid, on grid: the grid is used as a battery (excess is put on the grid, shortness is taken from the grid), hybrid: a battery pack will store the excess of energy and will be used a smuch as posssible while there is no sunpower available.

In Thailand, the PEA allows maximum a 10kW system to be on grid (which can put energy back on the net).

Following questions will be needed to be answered in order to dimension a solar PV system.

- What is your current average bill (and what is the maximum per month)?

- When is the energy needed? During day or night? Give the consumption pattern

- Is there a possibility to reduce the need in the night and us it in the day (for example cool down more during the night, pump up more in a reservoir, … = alternative battery)

- What is the total energy needed per 24h?

- What is the peak energy needed in 24h and how long is this peak?

What is the application for which energy is used? Residential, SME (if yes, what application? Cooling…Heating, …)

 - What is the location for the solar panels?

- On what can the panels be mounted? Check structure

- Can the panels be positioned in whatever what direction and angle (no roof)? If not, what are the restrictions?

- Are there shadow structures in the area to block sunlight??

Is there a net? How much kV? Mono or 3 phase net? Max Current available?

Can the extra energy be sold on the net? Depending on the inverter

- Can we get energy from the net if needed?

- What is the cost per kWh? Normally about 4,2 THB per kWh


For any installation, don't hesitate to contact us for advice! 

Water desalination


One way is to use Reverse Osmosis technic to filter the salt out of the liquid. This system uses pumps who consume a high amount of power. The installation has a low investment but regular maintenance is needed.


An alternative way is to use a CSP put trough system vaporise the water and condensate the steam. Also here, from time to time the piping system needs to be flushed to drain the salt from the system.

The best way is to use the CSP dish system which will concentrate the sunpower up to 80 times!

The energy is focused into a pot where water is inserted with a regular flow. The pot needs to be emptied from time to time to remove the salt residu.

Ice Making Machine

The principle of ice making is based on the physical features of ammoniak (CH3) which will be evaporated and condensed while exchanging energy. To accomplish this, a CSP - put trough system is used. 

Overview ice machine.png

During the day, CH3 is evaporated with the help of solar energy. The pressurized gas is cooled down in a condenser and stored in a condensater tank.

During the night, the valve of the condensate tank is opened and the gas is expanding while extracting heat from the isolated icebox creating ice. The ammoniak is condensed and concentrated in the absorber once more.

Hot water

Non concentrated Solar Heater

These heaters have a serie of vacuum tubes who capture the sunlight and exchange this energy in the top reservoir. The reservoir is insulated with polyurethane to maximize the heat transfer to the water pipe inside the reservoir. Below is a schematic view of the hot water circuit. To maximize the system, it is the best to put several systems in serie and use a boiler to store the hot water.

Most of the electricity in the world is still made in the same way. A turbine driving an alternator which creates electricity.

This turbine can be a fuel turbine, a gas turbine or a steam turbine.

The efficiency of a fuel turbine is around 30% and will not be discussed in this forum.

A gas turbine has an efficiency around 40% and a steam turbine around 20%. We discuss both since both can function in the same system.

Steam turbine

Steam turbine

There are still manufacturers in the world making steam turbines and the price is acceptable (read economical) for larger systems above 30kW (preferable 100kW) but most residential applications need a systemlower than 10kW and this market is almost none existing. 

We developed smaller steam turbine from which the efficiency will be tested. However, we like to focus more on the output than on the efficiency since we generate steam with sunpower... 

Steam turbine 10kW.png

Gas turbine

Gas turbine

Gas turbines (40% efficiency) are far more interesting than fuel engines (30% efficiency). The remaining energy in the hot air (650 degrees Celcius) create additional possibilities to increase the total efficiency!

For smaller installations, we see that micro turbines are used (smaller dimensions/ performance) if there is a demand for hot water as side product.

Water turbine

Water turbine

Using a vortex turbine to create electricity is still one of my favorite solutions since the investment is low and the maintenance during operations is almost none existing.

The only demand is to have a minimum height difference of 30 to 50 cm or more and a constant minimum volume per hour.

Water turbine.png
Water turbine small.png

For smaller water turbines (around 10kW) there are different types on the market like a kaplan turbine (see picture) or a pelton turbine. 

The efficiency of a water turbine is high... Smaller turbines reach above 80% while bigger installations go to 90% and more!



Depending on the loacation indoor or outdoor different technics can be applied... 

Indoor cooling can be made more efficient by grouping condensers in 1 unit. Alternative ways of cooling is to play on the humidity. For indoor, dehumidifying (to 30% and less) makes more sense than bringing extremely down the temperature.

However, for outdoor applications, humifying the air can drop the temperature easily without using huge energy resources!


Liquid Dessicant Cooling (for indoor)

Dessicant cooling

This cooling system uses a salt concentration to exchange humidity from a medium and cooling down the medium in the same time. The function is simular to a swamp cooler with that difference that here the humidity is under control.

The energy use is to 3 times lower than a traditional A/C system (with COP=3). 

Schematic view - liquid dessicant coolin


The air from a room is sent over a tower which will cool down and dry the air by sending concentrated lower temperature dessicant over a packing (read big surface) in the tower. The fine distributed dessicant needs to extract energy from the incoming air while absorbing the moisture from the incoming air. 

The diluted dessicant will afterwards be sent over a heat exchanger and a heater to be able to exchange the humidity in the next tower to the environment leaving colder concentrated dessicant again. 

This dessicant will be cooled in the heat exchanger and be extra cooled over a cooling system.

This system works best with a high relative humidity in the air. 


I prefer to use peltier elements to cool the dessicant liquid and extract the heat and electrical energy to cool by air (too avoid overheating of the Peltier elements and undo the cooling effect). The hot air wil be entered into the regenerator tower and help to increase the humidity transfer.

Second, the heater can be replaced in the day by a solar heater which brings the temperature easily above 60 degrees Celcius.

Storage of gas is a quite cheap way to accumulate energy and also easy to exchange between different locations.

We see in the world that next to the traditional electrical grid, a gas network is formed to transport gas between several locations.

Before the main gas used was LNG but we will see that more and more hydrogen networks will be used in the near future.
