Although they may look similar at first glance, these two types of ovens have distinct differences that can impact your curing process.

A tunnel oven is a large, heavy oven that is typically made out of steel or cast iron. The tunnel oven is heated from the bottom, which allows the oven to heat evenly and cure the items inside more slowly than other types of ovens.

Well ovens are typically made out of cast iron, but can also be made out of steel. The well oven is heated from the top and the heat circulates throughout the oven. This allows the oven to cure the contents inside evenly.


What is a Tunnel Oven?

A tunnel oven is a type of industrial oven that uses a conveyor belt to move product through a heated chamber. The heat source for a tunnel oven can be from natural gas, electricity, or steam. Tunnel ovens are often used in large-scale curing operations where high volumes of product need to be produced quickly and efficiently.

Tunnel ovens are large, continuous baking chambers with conveyor belts that move product through the oven on racks. They are typically used for high-volume operations and can bake large quantities of product at once.

Tunnel ovens are also very versatile, as they can be outfitted with various types of burners (natural gas, propane, oil, etc.) to accommodate different recipes.


What is a Well Oven?

A well oven is a type of commercial oven that is typically used for baking. It gets its name from the fact that it has a deep, well-like chamber that is used to hold products while they are being cured. Well ovens can be either gas or electric, and they typically have a variety of features that allows them to be customized for different types of curing.

For example, some well ovens come with a steam injection system that can be used to add moisture to the curing environment, which can help to improve texture of the baked goods.


Which type of oven is better for your Paint Plant?

If you’re running a paint plant, the type of oven you use can have a big impact on your production. Here’s a look at the two main types of ovens used in paint plants – tunnel ovens and well ovens – to help you decide which is best for your business.

Tunnel Ovens
Tunnel ovens are long and narrow, with a conveyor belt running through the center. Paint is applied to the product as it moves through the tunnel on the conveyor belt. Tunnel ovens are typically used for large-scale production and can be custom-designed to meet the specific needs of your paint plant.

Well Ovens
Well ovens are shallower and wider than tunnel ovens, with an opening in the center that allows products to be placed directly onto racks. Paint is then applied to the products using automated spraying equipment. Well ovens are often used for smaller-scale production or when products need to be handled more carefully.


The Pros and Cons of Tunnel Ovens

Tunnel ovens offer many benefits over well ovens, including faster baking  times, more consistent results, and less energy consumption.

However, there are also some drawbacks to using a tunnel oven, such as the need for a dedicated ventilation system and the possibility of uneven heat distribution.

The Pros and Cons of Well Ovens

There are a few key differences between tunnel ovens and well ovens that may make one or the other a better choice for your business. Let’s take a look at the pros and cons of each type of oven to help you decide which is right for you.


  • Can accommodate high-volume production
  • Very versatile
  • Can bake large quantities of product at once
  • Product moves continuously through the baking chamber on racks, resulting in more even baking


  • Must have sufficient clearance around the oven for the racks to move freely through the chamber; this can make placement difficult in some kitchens
  • More expensive than other types of ovens
