KEPKA Thermo Precision+

Designed for professional industrial applications.

Advanced Convection Chamber Furnace with PLC Control and Enhanced Safety

The KEPKA Thermo Precision+ is an advanced industrial convection chamber furnace, designed for applications requiring maximum process control, enhanced safety and extended automation capabilities.

This model builds on all core advantages of the Thermo Premium version and extends them with KEPKA proprietary PLC-based control, Siemens HMI operator interface and a significantly expanded safety and monitoring architecture.

The furnace is available in temperature variants of 250°C, 420°C and 720°C, covering a broad range of demanding industrial thermal processes.

Dynamic Turbulent Airflow for Precision Thermal Processing

As with all KEPKA Thermo systems, the Precision+ model is based on dynamic, turbulent convection airflow, generated by KEPKA’s proprietary thermo-circulation motors and rotors.

This airflow architecture ensures highly uniform heat transfer, elimination of temperature stratification and stable thermal conditions across the entire chamber volume.

The system performs equally well during fast dynamic heating cycles and long, stable thermal treatments, making it suitable for processes where temperature precision and repeatability are critical.

Multi-Section Heating with Independent Control

The KEPKA Thermo Precision+ furnace is equipped as standard with two independently controlled heating sections, typically located on the left and right sides of the chamber.
In larger configurations, the system can be expanded to up to four heating sections, providing even finer control of temperature distribution for large or complex loads.
Each heating section is controlled independently through solid-state power regulation, ensuring:

• low surface power density,
• elimination of local overheating,
• stable and uniform airflow heating.

As in the Premium model, heating elements are built on high-purity Al₂O₃ ceramic cores, structurally designed for continuous operation at temperatures up to 1300°C, guaranteeing long-term, failure-free performance even during extended industrial use.

PLC-Based Control with Siemens HMI

A key differentiator of the Precision+ model is its advanced PLC-based control system, developed by KEPKA and operated via a Siemens touchscreen HMI.
This platform provides a high level of transparency, control and flexibility for complex thermal processes.
Key features include:

• multi-level user access (operator, technologist, maintenance, service),
• full visualization of process curves and zone temperatures,
• complete process history and event logging,
• advanced recipe management for complex thermal profiles,
• online parameter adjustment during an active process cycle.

This control architecture allows precise process optimization while maintaining full traceability and documentation.

Enhanced Safety Systems
and Overheat Protection

The KEPKA Thermo Precision+ furnace incorporates an expanded safety architecture designed to protect both the product and the equipment.

An independent Overheat Protect system continuously monitors chamber temperatures via dedicated thermocouples.

If any heating section exceeds its defined safety threshold, power to the affected heating circuit is immediately disconnected through a dedicated safety contactor. This ensures immediate response to abnormal thermal conditions and provides an additional layer of protection beyond standard control limits.

The system is further enhanced with acoustic and visual signaling, using integrated signal towers to clearly indicate process states, alarms and operator actions.

Pneumatically Operated
Vertical Door System

In the Precision+ model, the furnace door is lifted vertically upward, providing safe and ergonomic access to the chamber.

Door movement is controlled via pneumatic actuators, ensuring smooth, controlled opening and closing under PLC supervision.

This solution improves operator safety, reduces mechanical strain and allows precise synchronization of door operation with the thermal process.

Remote Operator
Stand and Service Accessibility

The operator panel, including the Siemens HMI and safety controls, is mounted on a dedicated freestanding control stand, which can be positioned up to 3 meters away from the furnace.
This allows flexible workstation arrangement and improved operator comfort.
All electrical, pneumatic and control components are integrated into the rear or side sections of the furnace, providing easy access for maintenance and service operations.

Programmable Ventilation
and Controlled Cooling

The Precision+ model is equipped with an automatically controlled ventilation system, consisting of a motor-driven exhaust flap and extraction unit mounted at the top of the chamber.

Ventilation intensity and timing are fully programmable within the process recipe.

This system supports:

• controlled removal of volatile process by-products,
• precise management of chamber atmosphere,
• programmable cooling profiles.

By adjusting exhaust flow dynamically, the system allows controlled cooling or even assisted heating during the cooling phase, enabling highly accurate thermal transitions.

Heavy-Duty Industrial Construction

The KEPKA Thermo Precision+ furnace is engineered as a premium industrial solution for long-term operation.

The inner chamber is manufactured from stainless steel or acid-resistant steel, with selected components made from heat-resistant steels, ensuring durability under demanding thermal conditions.

Applications Across Advanced Industrial Sectors

The Thermo Precision+ furnace is dedicated to applications requiring high process security and advanced automation, including:

• polymer aging and stabilization,
• stress relaxation of technical components,
• aluminum heat treatment,
• medical material processing,
• automotive and aerospace components,
• technical plastics and elastomers.

Polish Engineering
and Manufacturing

The KEPKA Thermo Precision+ furnace is designed and manufactured in Poland, based on extensive experience in convection-based thermal systems and industrial automation.

This solution has been successfully implemented in advanced industrial environments worldwide.

Summary

The KEPKA Thermo Precision+ is a high-end convection chamber furnace combining dynamic turbulent airflow, multi-section heating, PLC-based Siemens HMI control, enhanced safety systems, and pneumatically operated vertical door mechanics.

It is the ideal choice for demanding industrial processes requiring maximum control, safety and long-term reliability.
