Efficiency and Safety, Redefined.

OLFO is not just a fryer; it is a high-performance system for Quick Service Restaurants (QSR) powered by revolutionary filtration technology. By continuously purifying the frying oil from microscopic particles and residues, OLFO maintains premium oil quality for weeks—not days. This eliminates the need for frequent oil changes, allowing you to use your oil far beyond the industry standard of 3 to 4 days. Manual filtration by kitchen staff is completely eliminated.

The Power of the Membrane:

At the heart of the system is a specialized membrane located in the lower unit. Proven in rigorous testing, this membrane can operate for over a year without needing replacement. It effectively captures particles and stores them in a dedicated reservoir for easy disposal.

Proven Technology, Future-Proof Investment:

Our membrane technology is built on principles used in high-precision industries like seawater desalination and aircraft environmental control systems. OLFO® is a forward-thinking investment for restaurants committed to streamlining operations, enhancing workplace safety, and securing a clear competitive edge.

Trusted by Global Leaders: IKEA, Taco Cabana & More

OLFO is redefining the standards for Quick Service Restaurants (QSR). By integrating revolutionary filtration technology into high-performance frying systems, we ensure that oil maintains its premium quality for weeks. This eliminates the need for oil disposal every few days and completely removes the burden of manual filtration from your kitchen staff.

Proven Performance: The Comparison

In direct head-to-head tests against high-quality conventional German-made fryers (equipped with standard semi-automatic filters), OLFO demonstrated a clear superiority. While traditional systems still required manual filtering every evening and resulted in heavily contaminated oil that had to be disposed of multiple times, OLFO reduced oil consumption by an additional 30% while maintaining total purity throughout the test cycle.

Smart Kitchens: Cloud Data & Analytics

The OLFO® E1 is fully IoT-enabled. Real-time data is transmitted to our secure servers for deep-dive analysis. Through intuitive dashboards, you can monitor: - System Health: Pressure levels and pump speeds. - Oil Quality: Live temperature tracking and built-in TPM (Total Polar Materials) sensors. - Remote Management: Adjust system parameters or perform a remote restart from anywhere in the world for maximum uptime.

Sustainable kitchen equipment reducing oil costs by 80 percent

Automatic filter membrane

The real highlight of the OLFO® fryer is its membrane. It continuously regenerates the frying oil. This means the oil no longer needs to be discarded after three days, but can remain in the fryer indefinitely. Frying oil is a foodstuff and a valuable ingredient. After each shift change, the dangerous and unpleasant task of manually filtering the hot oil is eliminated.
