The Ultimate Guide to Choosing the Right Combi Oven for Medium to Large-Scale Restaurants

In the fast-paced culinary world, the kitchen is the heart of your business. For medium to large-scale restaurants, efficiency is no longer a luxury—it is a necessity. This is where the Combi Oven becomes your most valuable asset.

By combining convection (dry heat) and steam functions into a single unit, a Combi Oven can replace multiple appliances, saving space and labor. However, with so many options on the market, which one is the right investment for your long-term success? Follow this comprehensive guide from PT Mastrada.

1. Determine Capacity Based on Production Volume

The first step is calculating how many portions you serve during peak hours. Combi Oven sizes are typically measured by the number of GN (Gastronorm) trays or racks.

• 6-10 Tray Capacity: Ideal for mid-sized restaurants serving 50–150 meals per session.

• 20 Trays and Above: Best suited for hotels, large-scale catering, or hospitals that need to serve hundreds or thousands of people at once (roll-in ovens).

Mastrada Tip: Don’t just buy for today’s needs. Choose a capacity that allows your business to grow over the next 2–3 years.

2. Energy Source: Electric vs. Gas?

This choice largely depends on your facility's infrastructure and local utility costs.

• Electric Combi Ovens: Generally offer more precise temperature control and simpler installation if your building has sufficient power.

• Gas Combi Ovens: Often the preferred choice for high-volume operations due to lower operational costs in regions like Indonesia, though they require more robust exhaust/hood systems.

3. Boiler vs. Injection Technology

How steam is generated is a technical detail that significantly impacts performance:

• Boiler Systems: Use a dedicated tank to generate steam. This is excellent for intensive steaming (such as dim sum or high-volume vegetables) because the steam saturation is incredibly stable.

• Injection Systems: Water is sprayed directly onto the heating elements. These units are more space-efficient, heat up faster, and are often easier to maintain as there is no boiler tank to descale.

4. Operational Ease (Smart Interface)

In a high-pressure kitchen, minimizing human error is key. Look for a Combi Oven with the following features:

• Pre-set Programming: Allows chefs to simply press a button for "Roasted Chicken," and the oven automatically adjusts temperature, humidity, and time.

• Automatic Cleaning: A self-cleaning feature is crucial. It ensures hygiene standards are met without requiring staff to manually scrub the oven interior every night.

5. After-Sales Service & Support

A Combi Oven is a significant investment. Purchasing advanced equipment without local technical support is a major risk. If your oven goes down during a busy shift, you need a team that can respond quickly with genuine spare parts.
