Oven Modernisation
Improve drying, heating and curing performance with efficient gas-fired oven systems.
Improve drying, curing and heating efficiency with gas-fired oven systems.
An oven that reaches temperature is not necessarily an oven that is working well.
Uneven heat distribution affects product quality. Poor air circulation creates hot and cold zones. Inadequate insulation raises running costs. Long drying cycles reduce throughput. Electric heating systems that were installed years ago carry high energy costs that gas-based alternatives can significantly reduce.
For transformer manufacturers, foundries and process industries, poor oven performance is not just an energy issue. It affects drying quality, batch consistency, cycle time and the reliability of the product going into service.
Energy & Cost
High operating cost — particularly in electrically heated ovens
Excessive heat loss through oven walls or doors
Older electric heating systems with high running costs
Poor insulation
Heat & Airflow
Uneven temperature distribution across the oven
Poor air circulation
Long drying or curing cycles
Consistency & Control
Inconsistent batch performance
Manual or inconsistent temperature control
Low process repeatability across shifts
Encon approaches ovens as engineered thermal systems.
Airflow, heat distribution, insulation, energy source and control are all assessed before a solution is recommended.
The modernisation can involve gas heating elements, improved air circulation design, ceramic fibre insulation, modular oven construction, CFD-led airflow and temperature analysis, upgraded controls, improved door seals or conversion from electric heating to gas-based systems.
RAD-HEAT Gas Heating Elements
Infrared gas heating tubes installed directly inside the oven, replacing electric, thermic fluid or hot air systems for working temperatures up to 550°C. Savings of 25–70% in operating cost compared to electric heating, with a payback period of 6–8 months. Installation typically completed in one day.
Gas-fired transformer drying ovens
Modular, relocatable ovens for transformer curing and drying, energised by gas heating elements or hot air generators. Operating cost savings of up to 50% compared to electricity and up to 20% compared to hot air generators. Ceramic fibre lining for minimum heat loss.
Core baking ovens
Batch and continuous type ovens for foundry core drying, energised by gas heating elements, hot air generators or electricity. Ceramic fibre insulation for reduced heat loss.
CFD-led design
In-house CFD analysis to optimise airflow and temperature distribution before build, reducing uneven zones and improving batch consistency.
Controls upgrade
Replacing manual or inconsistent temperature control with thermostatically controlled, repeatable systems.
Custom process ovens
Ovens designed and built for specific process requirements across pharmaceutical, food, battery, coating and other applications.
Selected around the drying or curing process and the load.
Oven modernisation is delivered through gas-fired oven systems, heating elements and controls.

Automation & Controls
Better process performance, lower energy cost, more consistent quality.
A modernised oven delivers batch after batch, shift after shift.
Energy & Cost
Lower operating cost
Up to 50% reduction using gas heating elements compared to electricity.
Reduced heat loss through improved insulation
Ceramic fibre lining holds heat inside the oven instead of the surrounding building.
Reduced CO₂ emissions
Gas heating elements reduce CO₂ emissions by 20–30% compared with electric heating.
Lower dependence on electric heating
Gas-based heating removes exposure to electricity tariffs and grid load.
Heat & Airflow
Improved temperature uniformity across the oven
CFD-led airflow design removes the hot and cold zones that affect batch quality.
Shorter cycle time
Faster, more even heating shortens the drying or curing cycle.
Improved air circulation
Airflow designed around the load rather than the enclosure.
Consistency & Control
Improved drying and curing quality
Even heat produces an evenly cured product through the batch.
Better batch consistency
The same result batch after batch, not only on the well-run ones.
More repeatable process control
Thermostatic control replaces manual setting as what holds the cycle.
