Josui (上水) — meaning "superior water" in Japanese — is a dedicated glass bottle washing ecosystem built from the ground up. Clients rent our proprietary equipment, featuring 3D-printed precision wash arms designed using AI-driven engineering for multiple bottle shapes — round, square, tapered, or custom. Powered by PTC ceramic heating elements for precise, energy-efficient sanitisation. A complete ecosystem for hotels, resorts, convention centres, and corporate venues across Malaysia.
Everything you need to wash, fill, seal, and brand your in-house glass water bottles.
Dedicated bottle washing machine with 3D-printed precision wash arms engineered for various bottle shapes. AI-calibrated spray patterns ensure every surface is cleaned. Filling station and water filtration included.
Available in 16, 25, or 36-bottle configurations. Precision-fit 3D-printed racks designed for Josui's proprietary wash arm system. Food-safe polycarbonate construction.
Premium 500ml and 1,000ml glass bottles with your hotel logo. Custom printing available. Elegant, reusable, and guest-friendly.
Custom-printed cap seals. Intact = untouched. Broken = tampered. The single most important trust signal for your hotel guests. Recurring consumable revenue.
We've reimagined bottle washing from the ground up using the latest advances in additive manufacturing, artificial intelligence, and ceramic heating technology.
Our AI system scans your bottle types — round, square, tapered, custom shapes — and generates optimised washing parameters for each. No more one-size-fits-all.
Each rack is 3D-printed using food-safe polycarbonate on our PioCreat G5 PRO. Micron-level precision ensures a perfect fit for any bottle shape or size.
Self-regulating PTC elements maintain optimal wash temperature without overheating. Energy-efficient, safer, and more durable than traditional heating elements.
Bottles washed, filled with filtered water, sealed with tamper-evident stickers. Returned bottles go through the cycle again. Zero plastic waste.
Every bottle cap carries a custom sticker. Your guest sees it intact — they know the water is fresh and untouched. It's the difference between a premium hotel experience and a questionable one.
The heart of Josui's wash performance is our Positive Temperature Coefficient (PTC) ceramic heating element — a major leap over traditional resistance heaters.
PTC elements automatically adjust their power output based on ambient temperature. No thermostat needed — they naturally maintain the ideal wash temperature without overheating or wasting energy.
As the element heats up, its resistance increases, naturally reducing power draw. This self-limiting behaviour cuts energy consumption by up to 30% compared to traditional heating elements.
No external feedback controls or diagnostic circuits needed. PTC elements cannot overheat — they automatically cap their temperature. Perfect for continuous commercial operation.
Ceramic PTC elements resist corrosion, mineral buildup, and thermal shock. Rated for 100,000+ hours of continuous use — outlasting conventional heating elements 3 to 5 times.
🔍 Research-backed: PTC ceramic heating technology is scientifically validated for energy efficiency, thermal stability, and long-term durability in commercial washing applications (Journal of Ceramic Science & Technology).

Quick answers about Josui, ESG impact, cost savings, and carbon reduction for Malaysian hotels and venues.
Every hotel, convention centre, and corporate meeting room that switches from single-use plastic bottles to Josui's reusable glass bottle system makes a measurable environmental impact.
Reusable glass bottles produce 85% fewer carbon emissions compared to single-use alternatives, and 75% fewer than single-use PET plastic bottles (Zero Waste Europe, 2023). A typical 300-room hotel switching to Josui can eliminate over 100,000 plastic bottles per year.
Malaysia generates over 653 tonnes of plastic waste entering waterways annually (UNESCAP). By switching to Josui's closed-loop reusable glass system, hotels and venues directly contribute to SDG 12 (Responsible Consumption) and SDG 14 (Life Below Water). Every bottle washed replaces a plastic bottle that would end up in landfill or ocean.
Be recognised as a sustainability leader. Josui helps you measure and report your plastic and carbon savings for your annual ESG report.
