Commercial Convection Oven Buying Guide 2026: 4, 6 and 10-Tray Sizes, Power and FOB Prices
A commercial convection oven is the workhorse of most professional kitchens: it bakes, roasts, browns and reheats with even, fan-forced heat at a fraction of the cost of a combi oven. If you are equipping a cafe, bakery, restaurant or hotel pastry section in 2026, this guide covers the sizes, power requirements, gas-versus-electric trade-offs and real FOB price brackets you need to specify the right model and avoid over-buying.
What is a commercial convection oven, and how is it different from a combi oven?
A convection oven cooks with dry, forced hot air. A fan (usually a reversing, bi-directional fan on better models) circulates heated air around the cavity so every tray cooks at the same temperature, eliminating the hot and cold spots of a static deck oven. That even airflow is why convection ovens brown pastry uniformly, roast meat faster and bake multiple trays of cookies or bread rolls at once.
The common confusion is with the combi oven. A combi oven adds a steam circuit (either a boiler or boilerless spray injection) so it can run dry convection, pure steam, or a blended combi mode. That extra capability roughly doubles or triples the price. A 10-tray electric convection oven typically lands at USD 1,200–2,400 FOB, while a 10-tray combi oven runs USD 4,500–7,800 FOB. If your menu is baking, roasting and reheating — and you do not need precise steam for sous-vide, proofing or delicate fish — a convection oven is the smarter spend. If you need full steam control, read our separate commercial combi oven buying guide instead.
What sizes do commercial convection ovens come in?
Capacity is counted in trays. Two tray standards dominate: the bakery tray at 600×400 mm, and the Gastronorm GN 1/1 at 530×325 mm. Always confirm which standard a quoted model uses, because a “10-tray” oven on 600×400 pans holds noticeably more than one on GN 1/1.
- 4-tray countertop: the entry model for cafes, kiosks and small bakeries. Footprint around 600×700 mm, sits on a bench or stand.
- 5 to 6-tray countertop: the most popular size for busy cafes, patisseries and mid-size restaurants. Bakes croissants, cookies, sheet cakes and roast trays in volume.
- 10-tray full-size: the floor-standing or stand-mounted production oven for hotels, central bakeries and banquet kitchens. A 10 tray convection oven is the typical specification when one oven must feed a full breakfast service or a bakery production line.
- Double-deck (2×5 or 2×6): two independent cavities stacked to double output without doubling floor space — ideal where two cooks bake different products at different temperatures.
Tray pitch (the gap between trays) matters as much as tray count. Tall items like proofed bread rolls need 75–80 mm spacing; flat cookies and sheet pans can run tighter. We configure tray pitch to your product at the factory stage, so the headline tray count actually matches your real output.
How much power does a commercial convection oven need?
Electric convection ovens are the most common export configuration. As a planning guide:
- 4-tray electric: 3.2–4.5 kW, 220–240 V single phase.
- 6-tray electric: 6.4–7.5 kW, 380–415 V three phase (some 6-tray run single phase).
- 10-tray electric: 12–16 kW, 380–415 V three phase, typically a 25–32 A circuit.
- Gas 10-tray: 18,000–26,000 BTU/h, with a small electrical supply (around 0.3 kW) for the fan and controls.
Two export details cause most field problems. First, frequency: Saudi Arabia and much of the Gulf run on 60 Hz, which changes fan-motor speed and rating — the oven must be built for it, not adapted on site. Second, gas type: natural gas and LPG need different injectors and pressure settings. We confirm voltage, frequency and gas type on the order and configure the unit before it ships, so it works the day it is uncrated.
Gas or electric convection oven — which should you choose?
Electric ovens give more even, controllable heat and are easier to install where a three-phase supply exists; they suit pastry, biscuits and delicate bakes. Gas ovens win where electricity is expensive or the grid is unstable, and where a generator already runs the site — common on remote and African projects. Gas recovers heat quickly after the door opens, which helps high-throughput roasting. For most hotel and restaurant bakery sections with reliable three-phase power, electric is the default; for sites running on diesel gensets or with high tariffs, gas often wins on running cost.
How much does a commercial convection oven cost in 2026?
Indicative FOB China price brackets (ex-factory, before freight and duty). Steam/humidity injection, stainless stands and proofer bases are priced separately.
| Model | Trays / standard | Power | FOB USD |
|---|---|---|---|
| Countertop convection | 4 × 600×400 | 3.2–4.5 kW / 220V | 280–520 |
| Countertop convection | 5 × GN 1/1 | 5–6 kW | 420–720 |
| Countertop convection | 6 × 600×400 | 6.4–7.5 kW | 550–950 |
| Full-size electric | 10 × 600×400 | 12–16 kW / 380V | 1,200–2,400 |
| Full-size gas | 10 × 600×400 | 18–26k BTU/h | 1,600–3,000 |
| Double-deck electric | 2 × 5 or 2 × 6 | 13–18 kW | 2,200–4,200 |
| Humidity / steam-injection option | add-on | – | +150–400 |
Compared with a combi oven, a convection oven is the budget-efficient choice: you are paying for even airflow and capacity, not a steam generator. Where a buyer truly only needs to bake and roast, specifying convection instead of combi can cut oven spend by 60–70% per station.
Key features to check before you buy (2026)
- Reversing fan: a bi-directional fan that alternates rotation gives noticeably more even colour across a full load than a single-direction fan.
- Humidity injection: a manual or programmed water spray adds a burst of moisture for crusty bread and shiny pastry — a cheaper halfway step toward combi performance.
- Controls: mechanical dials are robust and easy to repair; digital/programmable panels store recipes for consistency across shifts. Choose to match your staff.
- Cavity and racks: 304 stainless interior, rounded corners for cleaning, and chrome or stainless wire racks rather than thin pressed trays.
- Door and seal: double-glazed door, cool-touch handle and a replaceable silicone gasket — the gasket is a wear part, so confirm it is a stock spare.
- Energy efficiency: good cavity insulation and a tight seal cut both energy use and the heat dumped into your kitchen. CE and ETL-compliant builds are available where your market or insurer requires them.
How to choose the right convection oven for your venue
Match tray count to peak output, not average. A 60–cover cafe baking pastry through the morning is well served by a 5 or 6-tray countertop unit. A 150–200 room hotel running a breakfast bakery plus roasting needs a 10-tray, often with a proofer base. A standalone bakery or central kitchen producing for several outlets should look at a 10-tray or double-deck, or step up to a dedicated bakery production line built as a turnkey project where the oven is balanced against mixers, dividers and provers so nothing becomes a bottleneck. Caterers and banquet kitchens that move ovens between rooms value the lighter countertop and double-deck units on mobile stands.
When you source, working with an established manufacturer matters more for ovens than for simple stainless fabrication, because element life, fan balance and controls determine reliability. For a vetted starting point, see our guide to the top commercial kitchen equipment manufacturers in China.
Three things make a real difference on delivery. We build to your exact specification — voltage, frequency, gas type, tray pitch and finish — rather than shipping a generic unit. Every oven carries a 2-year warranty, and the wear parts that actually fail (fan motor, heating element, door gasket and control board) are kept in stock and dispatched in 3–5 days, so a fault never strands you for weeks. And production runs 25–45 days versus the 60–90 days that is common through distributors, which keeps project timelines intact.
Frequently asked questions
Is a convection oven the same as a combi oven?
No. A convection oven uses dry forced-air heat only. A combi oven adds steam, so it can run convection, steam or combined modes — useful for sous-vide, proofing and delicate cooking, but at two to three times the price. If you only bake and roast, a convection oven is the better value.
How many trays do I need for a hotel breakfast?
As a rule of thumb, a 10-tray convection oven supports a breakfast bakery and hot-roast service for roughly 120–200 covers. Smaller properties and cafes are usually well covered by a 5 or 6-tray countertop unit.
Can a convection oven bake bread and roast meat in the same kitchen?
Yes — that versatility is its main appeal. Add the humidity-injection option if crusty bread quality matters, and use the reversing fan and correct tray pitch for even results across a full load.
Can you build the oven for 60 Hz or LPG for my market?
Yes. We configure voltage, frequency (50 or 60 Hz) and gas type (natural gas or LPG) at the factory before shipment, and supply the matching documentation, so the oven is correct for your local supply on arrival.
What are the lead time and warranty?
Standard production is 25–45 days. Every oven includes a 2-year warranty with stocked spare parts dispatched in 3–5 days.
