Convection Systems ThermoTurbulence™ by KEPKA

KEPKA’s Convection Systems are engineered for industries where dynamic, turbulent airflow defines the quality, speed and repeatability of heat treatment. Built on over thirty years of expertise, our ThermoTurbulence™ platform delivers the fastest, most uniform and most stable heating conditions for chamber and tunnel furnaces. This technology is essential wherever polymers, aluminum, titanium alloys or technical materials require precise thermal control.

Engineering Dynamic Airflow for Modern Thermal Processing

KEPKA approaches convection not as an accessory, but as a core thermal engine. ThermoTurbulence™ was developed to ensure rapid and uniform heat distribution across any load — from small polymer parts to large aerospace components. Our systems power high-demand applications including automotive fuel-line thermoforming, BEV/PHEV battery-cooling conduits, aerospace aluminum structures, composite components and industrial plastics.

At the heart of ThermoTurbulence™ lies a high-temperature thermo-circulation chamber, built from alloys designed to resist creep and deformation above 850–900°C. Inside, specialized steel rotors create a combination of directed laminar flow and controlled turbulent motion, eliminating dead zones and ensuring even heat exposure regardless of product geometry, thickness or orientation.
Our convection motors are engineered specifically for harsh thermal environments. With reinforced windings, heavy-duty bearings, extended shafts, external cooling and radiators, they deliver years of quiet, stable and failure-free 24/7 operation — even under continuous high-temperature load.

Simulation-Driven Design CFD as a Core Engineering Tool

In KEPKA systems, airflow behavior is never left to chance. CFD (Computational Fluid Dynamics) is integrated into ThermoTurbulence™ project. Using full-chamber simulations, we analyze:

Pressure fields & airflow paths

We model how air compresses, accelerates and stabilizes inside the working chamber.

Temperature equalization

We simulate how heat moves through the load to remove cold zones and correct asymmetries.

Turbulence & laminar zone balance

Rotor geometry and chamber ducts are optimized to create the ideal blend of laminar direction and turbulent energy for maximum heat-transfer efficiency.
Heating elements are shielded to prevent direct radiation on the product. Only controlled convection reaches the load, preventing hotspots and protecting sensitive polymers and alloys.
ThermoTurbulence™ systems operate reliably across 100°C to 900°C, covering the full spectrum of low- and mid-temperature processes in industry, R&D and continuous production lines.

Every KEPKA convection installation is fine-tuned during commissioning. Airflow settings are calibrated to material type, loading pattern, heating curve, mass distribution and thermal sensitivity. The result is a refined airflow field that delivers rapid heat-up, exceptional uniformity and fully predictable process behavior.ThermoTurbulence™ has been deployed in hundreds of chamber and tunnel furnaces — from compact R&D units to large automotive production lines. In every case, the system provides:
