Product Overview
The Napoleon Apollo® 18 is designed for customers who want a dedicated charcoal smoker with excellent versatility in a manageable footprint. Its vertical water-smoker design encourages steady heat and smoke circulation while the water pan helps create the moist cooking environment traditionally used for long, slow barbecue.
Whether you're smoking brisket, ribs and poultry on the stainless steel grids or hanging sausages, fish and ribs from the supplied S-hooks, the Apollo® gives you multiple ways to use the available cooking chamber efficiently.
Low & Slow Smoking Performance
The Apollo® 18 is designed around controlled charcoal cooking. Three adjustable inlet vents allow you to manage oxygen entering the smoker, helping regulate charcoal burn rate and maintain the stable temperatures required for extended smoking sessions.
Adjustable smoke control lets you further manage airflow and smoke circulation, giving you greater control over the balance of heat and smoky flavour throughout the cook.
304 Stainless Steel Cooking Grids
The Apollo® 18 includes durable 304 stainless steel cooking grids designed to cope with the heat, moisture and extended cooking times associated with charcoal smoking.
- 304 stainless steel construction
- Low-maintenance cooking surface
- Designed for even heating
- Suitable for meat, poultry, seafood and vegetables
- Built for repeated outdoor smoking sessions
Precise Airflow & Temperature Control
Three adjustable inlet vents give you direct control over how much oxygen reaches the charcoal. Opening the vents encourages a hotter burn, while reducing airflow helps settle the smoker into the lower, steady temperatures required for traditional low-and-slow cooking.
The integrated ACCU-PROBE™ temperature gauge provides an easy visual reference at the smoker, while silicone-sealed probe ports allow compatible external temperature probes to be routed into the cooking chamber with reduced heat and smoke leakage.
Hang Ribs, Fish & Sausages
The lid incorporates a horizontal hanging bar together with five stainless steel S-hooks, providing another way to smoke food beyond placing it directly on the cooking grids.
This setup is particularly useful for sausages, fish, ribs and other foods that benefit from suspended smoking while making efficient use of the vertical cooking chamber.
Rotisserie Ready
A durable stainless steel rotisserie ring allows the Apollo® 18 to accommodate a compatible rotisserie setup for slow, even rotation of meats over charcoal heat.
Please note: the rotisserie motor, spit and associated rotisserie attachment are sold separately and are not included with the smoker.
Easy Access During Long Cooks
Large access doors with insulated handles make it easier to tend the charcoal, water pan and food during longer smoking sessions without having to completely dismantle the smoker.
The insulated lid handle provides safer, more comfortable handling, while the sealed probe ports make it easier to monitor internal food temperatures with compatible probes.
Modular Design & Mobility
Locking toggle latches securely connect the smoker sections during use while allowing the sections to be separated when required for transport, cleaning or storage.
Locking caster wheels make the Apollo® easier to move around your outdoor cooking area and allow it to be secured once positioned.
Outdoorium Expert Advice
Choose the Napoleon Apollo® 18 if you want a genuine dedicated charcoal smoker but don't need the larger capacity or footprint of the Apollo® 22. Its smaller diameter makes it a particularly practical choice for patios, courtyards and outdoor cooking spaces where room is limited.
You still retain the important Apollo® features — stainless steel grids, water smoking, controlled airflow, hanging hooks and rotisserie compatibility — making the 18-inch model a strong option for smaller households or customers who smoke moderate quantities rather than regularly cooking for large groups.
