Minairal is based in Bo Phut. The head office, the showroom and a service centre are on the island, so the team that assesses your site is the team that installs and maintains the system afterwards. Koh Phangan is served from Koh Samui.
Minairal designs, installs and services drinking water systems that produce mineral water on site in Koh Samui, from ambient air or from the existing water line. One agreement covers the system from the first visit to the end of its life.
We visit the site, count the users and the points of use, and check whether a reliable water connection exists. You receive a configuration, a capacity and a maintenance plan.
Machines are checked and configured before delivery, then placed, connected and tested on site. Every installation ends with a report signed by both parties.
Preventive checks, filter replacement and cleaning on schedule. The pre-filter is replaced every four to six months depending on the system, the other cartridges every twelve months, and TDS and pH are checked at each routine visit.
Technicians are on our payroll and parts are held at the Bo Phut centre. Same day in most cases, 48 hours at the latest.
Mains water in Koh Samui is not intended to be drunk at the tap. As elsewhere in Thailand, depending on the season it can carry chlorine and its by-products, sediment and heavy metals, with a bacteriological risk wherever the network is old or intermittent.
Island networks add two constraints of their own: salinity, and pressure loss at peak demand. A system on the mains has to cope with both. A system that makes water from the air does not depend on the network at all.
Bottled water is the usual alternative, and on an island it is the hardest one to move. Every litre arrives by boat and then truck, is chilled on the way and leaves again as waste. At two litres a day in half-litre bottles, one person accounts for 1,460 bottles a year.
The technology is decided at the site assessment. On the island, the first question is how far the water line can be trusted.
An Air system condenses humidity from the air and treats it on site. It needs a power socket and no plumbing, so it suits sites where the connection is unreliable or pressure drops at peak times, and points of use far from any pipe. It also takes water delivery off the site entirely, which on an island is the largest effect.
A Pure system connects to the existing water line: five-stage reverse osmosis at 0.0001 micron, remineralisation, hot 90°C and cold 4°C. Output is stable, and installation takes under an hour. It suits kitchens, staff areas and any point of use with a dependable supply.
Five of the six installations listed on our projects page are in Koh Samui. Client names are withheld at their request.
A luxury tented resort runs Air and Pure systems at multiple points of use.
A restaurant group uses Pure systems from kitchen preparation to table service.
A wellness centre runs Air systems across treatment and guest areas.
A villa management company has an Air system in each villa.
A kindergarten uses Pure systems as free-flow stations.
Free-flow stations for teams, with no more deliveries.
The head office in Bo Phut includes a showroom where the Air and Pure ranges can be seen side by side before any decision is made. Hours are Monday to Saturday.
The same address is the service centre for Koh Samui and Koh Phangan, with parts held in stock. When a filter is due or a system needs attention, the part and the technician start from the island.
One phone number and one email for every location. Support in English and Thai.
Yes. The head office and showroom are at 138/42 Moo 2, Tambon Bo Phut, Koh Samui, Surat Thani 84320. The Air and Pure ranges can be seen there before you decide. Hours are Monday to Saturday.
Yes. Koh Phangan is served from the Koh Samui service centre, by Minairal technicians and under the same agreement as sites on Koh Samui.
Same day in most cases, 48 hours at the latest. Technicians are on our payroll, two to five per service centre, and parts are held at the Bo Phut centre.
Mains water is not intended to be drunk at the tap. It can carry chlorine and its by-products, sediment, heavy metals and bacteriological risk where the network is old or intermittent, and island networks add salinity and pressure loss at peak demand. Our guide to tap water in Koh Samui covers the options.
It depends on the site. Air needs no water connection and keeps producing when the network does not. Pure filters the existing line and gives a stable output.
The choice is made at the site assessment, on four questions: the water connection, the daily volume, the space and the need for continuity.
Three service centres with parts held in each, and coverage across four provinces.
Tell us the site, the number of people and the points of use. The Bo Phut team comes back with a configuration, a capacity and a maintenance plan.
