Thermal oil technology for superior baking quality
In professional baking, the quality of the bake makes all the difference. A crispy crust, balanced crumb and perfect base are not left to chance — they depend on precision in heat transmission.
This is where GPG’s thermal oil bakery ovensstand out, offering superior quality, consistent performance, and energy efficiency in every batch.
What is thermal oil and how does it benefit baking?
Thermal oil is a heat-transfer fluid used in industrial processes as an alternative to air or water. Its key advantage is its high heat capacity — approximately twice that of air — making it a far more efficient system for generating and maintaining stable temperatures.
In industrial bakery ovens, thermal oil allows for uniform and constant heat distribution at all levels. Thanks to its high thermal inertia, it enables regular baking without fluctuations and optimised energy consumption.
How does a thermal oil bakery oven work?
At the heart of the system is the boiler, where thermal oil is heated and circulates evenly through the radiators on each deck via a closed (patented) circuit.
This technology ensures stable and homogeneous heat transmission, optimising oven performance and ensuring even baking at every level, with no temperature fluctuations or recovery times.
Advantages of baking with thermal oil technology
Radiation ovens with thermal oil heating — like our STATIC, STATIC REFRAC and MULTI REFRAC models — provide even baking, maximum energy efficiency and exceptional thermal stability.
They are designed for intensive production cycleswith no need for recovery time between batches. Ideal for artisan bakeries with high output, demanding bakehouses or large-scale production facilities that want to boost productivity without compromising quality.
Main benefits of thermal oil baking:
Radiation baking
Creates a static atmosphere similar to traditional ovens, without air circulation. This allows for the development of a quality crust and bottom, better retention of the bread’s natural moisture, and helps maintain its aroma and freshness for longer.
Surrounding,
even heat
Surrounding, even heat
The heat is transferred evenly to all levels of the oven, ensuring consistent baking in each piece. Ideal for hydrated and refined doughs, artisan breads, loaf breads, pastries, and confectionery.
High energy
efficiency
High energy efficiency
Thanks to the heat capacity of the oil, the system provides a stable and constant heat supply to the product, with lower energy consumption and maximum thermal efficiency.
Continuous production
Supports uninterrupted baking cycles with no downtime between batches, maximising output and streamlining workdays.
Reliability and durability
Under normal usage conditions, thermal oil does not require replacement or filtration.
Over 40 years developing thermal oil technology
At GPG, we have been developing thermal oil baking solutions for over four decades, adapting them to the real needs of every production model.
We design and manufacture ovens that combine innovation, efficiency and reliability, with one clear goal: delivering the highest baking quality in every batch.
From our first STATIC rack oven built in the 1980s, to more advanced solutions like STATIC REFRAC (with refractory stone and automatic loader) and the MULTI REFRAC deck oven, we have supported both artisan bakeries and large industrial producers.
Our latest innovation: STATIC PLUS installations that integrate two or more thermal oil ovens with a shared boiler, customised automation and future scalability.
An ideal solution for bakeries seeking maximum efficiency, consistency and quality.
What our bakers say about thermal oil ovens
Thermal oil ovens: versatility and performance for every bakery
From small artisan bakery workshops to large-scale industrial bakeries, thermal oil ovens have become a versatile, efficient, and high-performance solution.
Their ability to respect traditional baking processes helps preserve the craft and character of great bread. In high-output settings, their thermal stability and energy efficiency ensure consistent baking without compromising quality.
At GPG, we design tailor-made solutions for every baker. We manufacture rack ovens refractory stone ovens with full-load automatic loaders, and deck ovens all with thermal oil technology — tailored to your space, production and baking needs.
