Drinking water for hotels and resorts in Koh Samui.
On an island, every bottle a hotel serves has crossed the sea first. Minairal makes mineral-enriched drinking water on the property instead, from the air or from the existing line. Our head office, showroom and service centre are in Bo Phut, and a luxury tented resort on the island already runs Air and Pure systems.

What changes for a hotel on the island.
Bottled water reaches Koh Samui by ferry, then by truck, and leaves again as waste the island has to handle. For a resort, that chain means storage space, delivery slots, chilled stock and the risk of running short in high season.
The network has its own limits: salinity, and pressure that drops at peak demand. A Pure system on the line treats what the water carries. An Air system takes the network out of the equation, which matters most for villas, pavilions and beach outlets far from a pipe.
Producing water where guests drink it takes the boat out of the chain. It is also a story guests can see: water in a glass bottle on the table, made on the property, with no plastic left behind on the island.
A typical set-up for a Koh Samui resort.
Built around what island resorts ask for: a supply that keeps running, and as little as possible to ship in.

Air, independent of the network.
Water from humidity, filtered, sterilised and remineralised in the unit. The luxury tented resort we equip in Koh Samui runs Air and Pure at multiple points of use.

Koh Samui hotel questions.
Can our team see the systems before a trial?
Yes. The showroom at our head office, 151/35 Moo 1, Tambon Bo Phut, has the Air and Pure ranges running side by side, Monday to Saturday, 9:00 to 18:00. The free one-week trial then takes place on your own property.
Do you already work with resorts in Koh Samui?
Yes. A luxury tented resort on the island runs Air and Pure systems at multiple points of use. Client names are withheld at their request.
What happens when the island network is under pressure?
Air systems keep producing, because they make water from the humidity in the air and need only a power socket. Pure systems depend on the line, so outlets that must never stop are usually given an Air unit.
How fast do you respond to a fault in Koh Samui?
4 hours on average. Technicians and parts are based in Bo Phut, on the island.
