Koldux was founded in 2011 as the microclimate atelier of a Foshan metal and wood workshop established in 2009. We build humidors, museum-grade showcases, tropical wine vaults and bar islands — 3,800 m² of workshop, 38 artisans, 17 years of manufacturing behind us, and a client list that runs from Penang shophouses to Singapore penthouses.
Our starting point is not the cabinet. It is the material behaviour: how Spanish cedar buffers humidity, how optical glass handles glare, how bronze PVD ages against a coastal climate, how a gasket behaves after two thousand openings. We design around those facts instead of hiding them behind a specification sheet.
The result is furniture that keeps working in the places where ordinary preservation furniture quietly fails.
Capabilities
Cedar work
Spanish cedar (Cedrela odorata) air-cured six months, hand-selected for grain and aroma, left unsealed on the interior face so it can buffer humidity.
Microclimate systems
Closed-loop ultrasonic misting on the dry side, desiccant-assisted drying on the wet side, sub-decibel inverter cooling, and a controller tuned for tropical ambient swings.
Metal & stone
SUS304 bronze PVD bodies, hand-finished edges, and precision joints to natural stone — the detail that separates an atelier piece from a cabinet.
Optical glazing
Low-iron anti-reflective glass with 99% transmission, UV blocked at the surface, so a collection can be lit without being damaged.
Culture
Three habits inherited from a family workshop, kept because they still make better objects.
01
Let the material decide
Cedar is not a lining, it is a working component. If sealing the interior would look cleaner and perform worse, we leave it unsealed and explain why.
02
Design for the second decade
A humidor should still close properly after ten years of daily use. Hinges, gaskets and seals are chosen for cycle life, not for the first photograph.
03
The collector is the client, not the specifier
Collectors notice the sound of a door, the smell at opening, the way a tray slides. Those are engineering decisions, and we treat them as such.
Quality
Testing a tropical product
—Every humidor runs a 72-hour humidity stability test at 30 °C ambient before crating.
—Cedar moisture content measured on receipt and again before assembly.
—Ultrasonic modules bench-tested for 1,000 hours; controllers soak-tested for drift.
—Crated with desiccant and a humidity indicator so the client can verify condition on arrival.
Clients
Private collectors
Bespoke humidors and display walls, dimensioned to the room and to the collection.
Cigar lounges & retail
Multi-unit humidors with consistent cedar sourcing and serviceable components.
Museums & galleries
Passive and active showcases with optical glazing, security locking and conservation-grade materials.
