Everything You Need To Know About Different Types of Water Dispensers

Whether you manage bustling offices, busy hospitals or outdoor recreation areas, the right water dispenser keeps employees, visitors and students refreshed, protects their health and helps you meet sustainability goals.

For more than a century, OASIS has earned a global reputation for delivering innovative, eco-friendly water dispensers that make clean drinking water accessible to millions. From touch-free bottle fillers that help curb germ transmission to rugged outdoor water fountain options built to withstand the elements, we combine smart engineering with durable materials to serve facilities in every industry.

This guide is designed specifically for facility managers like you. Below, you’ll find a clear breakdown of the main types of water dispenser solutions we offer, the features that set each model apart and practical tips for choosing the best fit based on demand, space, maintenance requirements and budget.

OASIS Water Dispensers: Finding Your Perfect Match

Every facility operates differently, but they all share a common need: dependable access to clean, great-tasting, cold water. We meet that challenge with a portfolio of models engineered for varied foot traffic, available space, water source constraints and budget considerations. By combining intuitive design, durable materials and a range of purification and activation technologies, we ensure you never have to settle for a one-size-fits-all approach. Instead, you can choose the dispenser style that aligns perfectly with your building’s layout, user demand and sustainability goals.

Bottle Fillers: Versatile Hydration Solutions

When your priority is rapid, touch-free refills for students, staff or travelers carrying reusable bottled water, OASIS bottle fillers deliver unmatched convenience. The lineup spans several distinct styles, each tailored to specific installation requirements:

Contactless Water Dispenser

• Electronic eye activation eliminates shared touchpoints, reducing bacteria spread.

• Built-in water filter status monitor and bottle-count display promote proactive maintenance and sustainability.

• Automatic 10, 20 or 30-second shutoff prevents overflow and water waste.

Freestanding Water Dispenser

• Shares the same compact footprint as traditional freestanding water fountains, simplifying retrofits.

• Integrated drain removes the need for drip-tray emptying.

• Front panel detaches for quick access to filters and cooling components.

• Fully ADA-compliant for inclusive access.

In-Wall Water Dispenser

• Modular frames can be shipped separately at no extra cost, allowing installation early in the construction timeline. Designs are future-ready, meaning you can have the order shipped separately to the finished unit when the site is prepared, knowing it will fit the pre-installed frame.

• Recessed or semi-recessed designs save hallway space while meeting aesthetic goals.

On-Wall Water Dispenser

• Signature Tilt ‘N Tether system enables sub-one-minute filter changes — just loosen two screws, tilt forward and swap the cartridge while standing.

• Automatic water shut-off in the quarter-turn filter head means no supply shut-off necessary.

• One filter serves both the bottle filler and any paired drinking fountain, lowering maintenance time and cost.

• Available with electronic, mechanical or combo activation options, plus filtered or refrigerated configurations.

Outdoor Water Dispenser

• Vandal-resistant designs feature 18-gauge or marine-grade 316 stainless steel and embossed branding that won’t peel or fade.

• Choose manual push-button activation; can incorporate filter monitors and bottle counters.

• Industry-exclusive outdoor filter kits can retrofit existing units, extending clean drinking water to parks, campuses and transit hubs.

QUASAR: Advanced Disinfection Technology

Our exclusive QUASAR system integrates UV-C LEDs directly at the point of dispense, bathing every drop in pathogen-neutrolizing light. Independent clinical testing confirms up to 99.9% reduction of major waterborne threats — including Legionella, Cryptosporidium and Pseudomonas — before water reaches the water bottle or bubbler. That final barrier is critical for facilities where vulnerable populations rely on consistently safe drinking water.

Beyond its impressive efficacy, QUASAR is engineered for long-term value:

• Mercury- and chemical-free LEDs eliminate hazardous materials and disposal concerns.

• Energy-efficient operation draws minimal power and never heats the water, keeping utility costs in check.

• A built-in fail-safe disables the dispenser if the UV-C module stops functioning, ensuring continuous protection.

• With an expected 10-year lifespan, QUASAR outlasts traditional UV bulbs and removes routine bulb replacement from your maintenance schedule.

If your needs evolve — say you add bottle fillers to existing fountains — streamlined conversion kits let you upgrade quickly without purchasing entirely new units. With smart design and thoughtful accessories, we ensure maintenance never takes more time or costs more money than necessary.

Water Coolers and Drinking Fountains: Reliable, Flexible Choices

For settings where bottle filling isn’t the only priority, we offer a broad range of water cooler dispenser options and fountains engineered to handle everything from steady indoor traffic to outdoor climates. Consider these models when you need traditional sip or gulp options in addition to bottle filling:

• Contactless fountains and coolers.

• Freestanding floor models.

• In-wall recessed or semi-recessed units.

• On-wall surface-mounted and bi-level options.

• Outdoor stations.

• Vandal-resistant constructions.

Key features that make these dispensers stand out include:

• Contactless activation with electronic eye sensors, perfect for healthcare, education and corporate environments seeking to minimize shared surfaces.

• Heavy-gauge steel or 14-gauge stainless cabinets on freestanding and outdoor units for maximum durability.

• StreamSaver bubbler design that reduces water waste by up to 50%, helping you save money and meet sustainability benchmarks.

• High-left or high-right versatility allows installers to flip split-level fountains on site - no special SKUs required.

• Outdoor models boast tamper-proof screws, keyed-in bubblers and outdoor-rated components, plus optional filtration for reliable vandal-resistant coolers and fountains.

• Stainless steel access panels on in-wall units keep chillers and filters secure yet easily reachable for routine service.

• Optional refrigerated, filtered and combo configurations let you tailor each unit to your facility’s specific water quality and demand profile.

These thoughtfully engineered options ensure you can match any space, usage pattern or budget without compromising on filtered water quality or user experience.

Tips and Tricks for Maintaining Your Cold Water Dispenser

Once you’ve selected the best water dispenser for your business, keeping it in peak condition is the key to uninterrupted hydration, consistent water quality and long-term savings. A proactive maintenance routine safeguards users, protects your investment and maximizes uptime.

Regular Cleaning and Sanitizing

Even the most advanced models need basic care to stop mineral buildup and biofilm. Wipe exterior surfaces daily, clean nozzles and bubbler heads weekly, and wipe down units every three months, or when they appear dirty. Pair these quick tasks with a quarterly internal inspection so small issues never have the chance to become costly repairs.

Purification Technologies That Go Beyond the Basics

We integrate several layers of defense against contaminants, each playing a distinct role in delivering safe drinking water:

• UV-C LEDs (QUASAR) neutralize harmful microorganisms at the exact point water leaves the dispenser, helping you maintain superior hygiene without chemicals or mercury.

• Silver-ion antimicrobial materials are molded into high-touch components, continuously inhibiting bacterial growth on surfaces users contact most.

• High-performance lead-reduction and cyst filters trap particulate class 1, chlorine, odor-causing compounds and other contaminants to ensure crisp, fresh drinking water for employees and visitors.

Industry-Exclusive Filtration That Meets Diverse Challenges

To prepare your facility for any water source or installation environment, we offer filtration system options that do more than the typical lead-and-chlorine removal:

• Pharmaceutical reduction cartridges target trace medications that municipal treatment plants don’t always capture.

• Outdoor-rated filters withstand temperature swings and humidity, bringing purified water to parks, stadiums and construction sites.

• Universal compatibility across indoor and outdoor product lines means you can stock a single filter SKU for hundreds of models, simplifying inventory management and saving money.

Convenient Service With Tilt ‘N Tether

Changing a traditional filter can take time - often requiring you to kneel, shut off the water line and remove multiple panels. The Tilt ‘N Tether fast-change system eliminates that hassle. Just loosen two side screws, tilt the unit forward on its safety tether and swap the cartridge in under a minute. No water supply shutoff, no extra tools and no need to move heavy equipment.

Know When It’s Time to Replace

Most OASIS filters last between six and 12 months, but usage volume, local water quality and contaminant levels can shorten or extend that interval. Keep an eye on the built-in filter status monitor or bottle counter for real-time cues, and schedule replacements more frequently in high-demand offices, restaurants or healthcare settings where safe drinking water is mission-critical.

Unlock the Best Hydration Solution for Your Facility

From compact on-wall bottle fillers that save space to vandal-resistant fountains built for outdoor parks, we deliver a bottleless dispenser for every setting and budget. Each model pairs trusted engineering with thoughtful features like contactless activation, fast filter changes and powerful UV-C disinfection, so you can provide safe drinking water while meeting sustainability and compliance targets.
