JESA ProHeater – Mobile High-Temperature Heater Controller for 3D Printer Build Chambers and Filament Dry Boxes | up to 150 °C chamber / 190 °C outlet

🔥 JESA ProHeater – mobile high-temperature heating controller for 3D printer build chambers and filament dry boxes

    The JESA ProHeater is a mobile high-temperature heating and dry box controller for demanding     3D printing applications. It was developed to precisely, safely and conveniently control the temperature of printer chambers,     enclosures and filament dry boxes.  

    With real achievable temperatures of up to 150 °C chamber or process temperature     and up to 190 °C outlet temperature, the JESA ProHeater is particularly suitable for technical     filaments, heated build chambers, enclosures and intensive drying processes.  

    Thanks to precise PID temperature control, two independent PT100 temperature measurements     and additional outlet temperature monitoring, the JESA ProHeater enables stable temperature control     with an extended safety concept.  

    A key advantage is its flexible use: thanks to a simple mounting mechanism with     magnetic counter plates, the JESA ProHeater can be moved between different application areas within seconds.     This allows one single heater to be used, for example, for a dry box, build chamber and enclosure.  

🔥 High-temperature operation up to 150 °C chamber temperature and 190 °C outlet temperature

    The JESA ProHeater reaches high temperature ranges that are especially relevant for technical filaments, intensive     drying processes and heated 3D printer build chambers.  

    The combination of precise control, powerful heating management and separate outlet temperature monitoring     enables controlled temperature management even in demanding applications.  

   
• Up to 150 °C chamber/process temperature
   
• Up to 190 °C outlet temperature
   
• Suitable for heated 3D printer build chambers and enclosures
   
• Ideal for powerful filament drying
   
• Designed for technical materials and demanding temperature processes
 

🧲 Mobile use – one heater for multiple applications

    Instead of needing a separate heater for each application, the JESA ProHeater can be used flexibly wherever heat is needed.     Using prepared magnetic counter plates, the heater can be attached, removed and reused at another     application point quickly and easily.  

    This allows the same JESA ProHeater to be used first on a filament dry box and then on a 3D printer build chamber     or enclosure, for example.  

   
• Quick changeover between dry box, build chamber and enclosure
   
• Easy attachment using magnetic counter plates
   
• One heater for multiple 3D printing applications
   
• Flexible use without permanent fixed installation on only one system
   
• Practical for workshops, printer farms, prototyping and technical filaments
 

🌡️ Precise temperature control

    The heater is controlled via finely adjustable power control. This allows the temperature to be kept stable     and adapted to different applications – from a heated build chamber to controlled filament drying.  

   
• PID temperature control with adjustable parameters
   
• Integrated PID auto-tuning
   
• Timer operation up to 99:59 hours
   
• Humidity-dependent operation with optional sensor
   
• External start contact for flexible integration
 

🛡️ Extended safety concept

    The JESA ProHeater uses a dual PT100 system: one sensor controls the target temperature,     while a second sensor monitors the exit or outlet temperature. If a limit value is reached, the heating power     can be reduced early or the heater can be switched off.  

    In addition, a hardware-based overtemperature protection via STB is planned. This works independently     of the control electronics and provides additional safety in case of a fault.  

   
• Dual PT100 monitoring
   
• Exit/outlet temperature with soft limit and hard limit
   
• Shutdown in case of sensor error
   
• Limitation of the maximum target temperature
   
• Automatic fan run-on
   
• Hardware-based overtemperature protection via STB
 

📱 Operation directly on the device or via web interface

    Operation is carried out directly on the device via a color display with rotary encoder or conveniently via the integrated     web interface. Live values, settings, PID parameters and history graphs can be viewed and adjusted there.  

    The web interface is optimized for smartphone use, making it convenient to use in workshop,     printer or production environments. The interface is currently available in     German and English.  

   
• Color display with configurable display fields
   
• Operation via rotary encoder
   
• Smartphone-optimized web interface with live values
   
• Web interface currently available in German and English
   
• 60-minute history for temperature and heating power
   
• Firmware update via browser
   
• All settings stored directly on the device
   
• Local operation also possible without Wi-Fi
 

🖨️ Klipper-compatible

    The JESA ProHeater can optionally be integrated into Klipper, making it especially suitable for     modern 3D printing setups with Mainsail or Fluidd. Target values, status and control commands can be processed     directly via the system.  

   
• Klipper integration possible
   
• Use as an additional temperature sensor
   
• Control via defined commands
   
• Suitable for Mainsail and Fluidd environments
 

🧪 Optional sensor extensions

    Additional sensors can be integrated for extended applications. In addition to humidity and temperature sensors,     connection options for VOC/air quality sensors are also planned in order to additionally monitor     air quality in the build chamber or dry box.  

   
• Optional humidity sensor for drying operation
   
• Optional VOC/air quality sensor connection
   
• I²C interface for sensor extensions
 

🏭 Typical application areas

🏗️ Planned certification & industrial suitability

    For the fully assembled series version of the JESA ProHeater, complete technical documentation     including CE conformity assessment, hazard analysis and safety-related testing is planned.  

    The goal is a professional and industry-ready solution for continuous use in the field of     3D printing, enclosure heating and temperature-controlled processes.  

    This includes, among other things:  

   
• CE conformity assessment
   
• Hazard and risk assessment
   
• Documentation of safety-related functions
   
• Overtemperature protection concept
   
• EMC-relevant design
   
• Technical documentation and test documents
 

    The DIY version is fundamentally based on the same technical concept and safety concept     as the assembled series version and is designed accordingly to also meet the technical requirements.  

    With the DIY version, you receive all required electronic and mechanical components to build the system.     The required housing and mounting parts only need to be printed by yourself, and the system then needs to be assembled     and wired.  

    Thanks to the detailed step-by-step operating and assembly instructions, assembly is straightforward for anyone     with basic experience in soldering, screwing and electronics assembly.  

    Of course, we are available to support you with questions regarding assembly, commissioning and configuration.  

    However, since assembly, wiring and final installation of the DIY version are carried out by the user,     we cannot assume any warranty for the finished overall assembly, the specific build or final conformity.  

ℹ️ Note on the beta phase

    The JESA ProHeater is currently still in the beta or prototype phase.     Functions, technical specifications and scope of equipment may still change before the final series version.
