Henny Penny Open Fryer | High Volume

An open fryer is a deep fryer in which oil is exposed to the air, unlike pressure fryers, which use a sealed chamber.

Henny Penny open fryers are ideal for fries, chicken tenders, fish, and other crispy fried foods.

• Open fryers cook at normal atmospheric pressure, making them ideal for crispy and crunchy foods.
• Pressure fryers cook under pressure, which locks in moisture and is better for juicier products like bone-in chicken.

Pricing varies depending on size, features, and configuration.

Entry-level models start around $13,000 CAD, while high-capacity, fully loaded units can range up to $66,000 CAD.

Henny Penny open fryers are widely used in quick-service restaurants (QSRs), convenience stores, full-service restaurants, grocery delis, and hotels.

You can use any liquid or solid shortening in Henny Penny fryers.

*If using solid shortening, it needs to be melted down before putting it in the fryer. Solid shortening is not recommended for Evolution Elite Open Fryers or F5 Open Fryers as it won’t work with the automatic oil top-off function.

Oil capacity varies by model, but most Henny Penny fryers hold 30-130 lbs of oil per vat.

• Evolution Elite – 30 lbs oil per vat
• 320 series – 65 lbs oil per vat
• 340 series – 90 lbs oil per vat
• Velocity Open Fryer – 130 lbs oil per vat

All Henny Penny fryers come standard with built in filtration systems!

The built-in SmartFilter® system automatically drains, filters, and returns the oil in under 4 minutes. This reduces downtime and ensures consistent food quality.

With daily filtration, you can extend oil life significantly. Depending on food volume and type, oil typically needs changing every 3 to 7 days, but high-efficiency Henny Penny fryers can stretch that further with proper filtering and oil management it can triple the oil life.

Henny Penny fryers work seamlessly with bulk oil management systems like Frontline International, allowing you to pump out used oil safely and efficiently. This reduces manual handling, improves kitchen safety, and minimizes spills.

It is recommended to be done every time you change your oil.

A boil-out should be done at least once a week (or as needed) to remove carbon buildup and maintain fryer efficiency. This helps prevent oil degradation and extends the life of your equipment.

Henny Penny open fryers heat up in about 15-20 minutes, depending on oil capacity and fryer type. From idle mode, the oil can be heated to temperature in as fast as 5 minutes.

For every 18°F you reduce your frying temperature, you can effectively double the life of your oil.

Henny Penny fryers are designed with fast recovery times, meaning they quickly return to optimal cooking temperature after filtering. This ensures minimal downtime and keeps food moving efficiently.

It all depends on how your fryer is configured and how your kitchen operates. Henny Penny’s SmartFilter® technology allows you to schedule filtration during non-peak hours. Even if filtering is needed mid-rush, the process takes less than 4 minutes, keeping disruption to a minimum.

Common issues include:

• Thermostat issues (may need recalibration or replacement)
• Clogged burners or heating elements
• Low gas pressure or electrical issues
• Dirty oil or lack of filtration causing buildup

• Drain the oil and filter it using the built-in filtration system.
• Scrub the vat with a fryer-safe cleaner.

With proper filtration and oil management, you can extend oil life up to 7 days or longer.

Signs that oil needs changing include:

• Darkened colour
• Excess foaming
• Smoking at normal frying temperatures

*It is important to test the oil before replacing it! We recommend 3M Oil Quality Test Stripes, which you can compare to the guide to understand your oil. Frontline Systems has a built-in digital oil reader.

• Never overfill oil to prevent spills.
• Never mix water with hot oil (this causes dangerous splattering).
• Use proper PPE when handling hot oil.
• Keep a Class K fire extinguisher nearby for oil fires.
• Needs to be under a fire suppression hood vent system

Extending oil life starts with managing these six key culprits that break it down:

1. Heat – The higher the temperature, the faster oil degrades. Reducing frying temperature, even slightly, can dramatically extend oil life.
2. Air – Prolonged exposure to air causes oxidation, breaking down oil quality. Always cover vats when not in use.
3. Water – Water from frozen foods or cleaning can cause oil to foam, splatter, and degrade faster.
4. Salt – Salt accelerates oil breakdown and should be added after frying, not over the fryer.
5. Food Particles – Crumbs left in the oil burn and degrade it quickly. Regular filtering helps remove them.
6. Detergent – Residue from poor cleaning practices can contaminate oil. Always rinse fryers thoroughly after cleaning.

Pro tip: DSL’s Henny Penny fryers with built-in SmartFilter® systems automatically combat many of these oil enemies, saving you money and keeping food quality high.

Consider:

• Menu size & volume (high-demand kitchens may need multiple vats)
• Oil Capacity (Henny Penny models range from 30-130 lbs per vat)
• Filtration needs
• Space & Layout
