Whether you prefer a more open RDL draw or a tighter MTL experience, XLIM 4 gives you the flexibility to find your preferred setup.
So, what makes XLIM 4 stand out? Let’s take a closer look.

Your airflow. Your draw. Your preference.
Meet the New XLIM Cartridge with UNITECH 3.0
One of the biggest upgrades to XLIM 4 is the all-new XLIM Top Fill Cartridge UNITECH 3.0.
But what exactly is UNITECH 3.0?
What Is OXVA UNITECH 3.0?
UNITECH 3.0 is OXVA’s upgraded cartridge technology, developed to optimize e-liquid delivery, heating, airflow, and sealing as one integrated system.
Instead of focusing on a single component, UNITECH 3.0 refines the overall cartridge structure — from airflow and coil contact to cotton wicking and internal sealing.
The result is a cartridge designed around three key advantages:
Rich & Punchy Flavor
Optimized airflow, heating efficiency, and e-liquid delivery work together to provide a fuller and more consistent flavor experience.
30-Second Priming
An upgraded wicking structure helps the cotton absorb e-liquid quickly and evenly, allowing a new cartridge to be ready in just 30 seconds after filling.
Enhanced Anti-Leak Protection
Improved internal barriers and sealing help minimize e-liquid leakage, keeping your everyday experience cleaner and more convenient.
Together, these upgrades make UNITECH 3.0 more than just a new cartridge — it’s a complete refinement of the XLIM experience.
Rich & Punchy Flavor — The XLIM Taste You Love
Flavor performance depends on more than just the coil.
Airflow, heating efficiency, and e-liquid delivery all play an important role in how consistently a cartridge performs.
With UNITECH 3.0, OXVA has optimized these key elements to deliver the rich, punchy flavor that XLIM users know and love.
25% Lower Draw Resistance — Smoother, Easier Draws
The upgraded curved airway is designed to reduce airflow turbulence and help air move more smoothly through the cartridge.
With 25% lower draw resistance, UNITECH 3.0 provides an easier, smoother draw while maintaining satisfying vapor production.
The result?
A more comfortable draw with rich flavor in every puff.
25% More Vapor — More Vapor, Fuller Flavor
UNITECH 3.0 also improves the contact between the mesh coil and cotton, helping e-liquid reach the heating area more evenly and efficiently.
This optimized structure delivers 25% more vapor, contributing to denser vapor production and a fuller flavor experience.
It’s an upgrade designed to help you get more from every refill.
Over 80% Flavor Performance After 10 Refills
A great cartridge shouldn’t only taste good when it’s brand new.
UNITECH 3.0 features a dual-layer cotton structure designed to deliver e-liquid quickly and evenly to the heating element.
According to OXVA testing, UNITECH 3.0 maintains over 80% of its flavor performance after 10 refills.
That means more consistent flavor over repeated refills, rather than relying on that “new cartridge” feeling alone.
Performance figures are based on OXVA testing. Actual results may vary depending on e-liquid, usage habits, and operating conditions.
30-Second Priming — From Fill to Flavor in Just 30 Seconds
When using a new cartridge, proper priming is essential.
The cotton needs enough time to absorb e-liquid before the heating element is activated. Insufficient saturation may result in dry hits or an unpleasant burnt taste.
UNITECH 3.0 makes this preparation easier with its upgraded wicking structure.
Simply fill the cartridge and allow 30 seconds for priming before use.
Fill. Wait 30 seconds. Enjoy.
It’s one more small improvement that makes the everyday XLIM experience easier.
