🔥 JESA ProHeater – mobile 3-in-1 high-temperature heating system for 3D printing applications
The JESA ProHeater is a mobile high-temperature heating system for controlled thermal processes in 3D printing environments. It was developed for applications in which temperature needs to be built up, regulated, monitored and maintained reproducibly.
The system combines a heater, fan, temperature control, sensor monitoring, display and web interface in one compact unit. The current design provides 1.6 kW of heating output and an airflow of 80 m³/h. The maximum current draw is 7.5 A. This makes the JESA ProHeater suitable for several common 3D printing applications, including heated build chambers, filament drying boxes, and controlled drying and annealing processes.
Its key advantage is flexible use: one ProHeater can be used at several prepared installation points. Magnetic mounting plates allow the system to be attached, removed and transferred to another application quickly.
In brief: one ProHeater – three powerful applications in 3D printing.
🔥 3 applications – 1 system
Controlled heat is essential in many 3D printing applications. Engineering polymers benefit from a temperature-controlled build chamber, filament should be kept dry before and during printing, and printed components can be post-processed through defined heat treatment depending on the material.
The JESA ProHeater was developed specifically for these applications and can be moved flexibly between them.
- Heat a build chamber: For controlled temperatures in 3D printer build chambers and enclosures.
- Dry filament: For defined drying processes in a filament drying box.
- Anneal printed parts: For controlled post-print heat treatment.
🧲 Mobile use – switch flexibly between multiple applications
The JESA ProHeater is not limited to one fixed installation point. Its straightforward mounting system with magnetic mounting plates allows the heating system to be relocated within seconds.
The same ProHeater can therefore be used on a filament drying box first, transferred to a 3D printer build chamber, and later used for an annealing process.
- Quick changeover between drying box, build chamber and annealing application
- Simple attachment using magnetic mounting plates
- One heating system for several prepared installation points
- Ideal for workshops, print farms, prototyping and engineering materials
- Particularly useful when several printers or applications require controlled heating
🌡️ Controlled temperature management
The JESA ProHeater uses precise temperature control. The required target temperature is set, measured and actively regulated through the heating output. This allows the thermal process to be controlled and adapted to the specific application.
The ProHeater uses a dual-PT100 concept for temperature measurement. One sensor measures the chamber or process temperature, while a second sensor separately monitors the air outlet temperature.
- PID temperature control for controlled thermal processes
- Control of the chamber or process temperature
- Separate monitoring of the air outlet temperature
- Dual-PT100 system for control and monitoring
- PID auto-tuning for adapting the control parameters
- Timer operation for defined drying and annealing cycles
🔥 For engineering materials and demanding applications
The JESA ProHeater is designed for applications in which a stable and traceable temperature environment is important. Defined temperature management can be a decisive part of the overall process, particularly when working with engineering filaments, heated enclosures and controlled drying processes.
Depending on the setup and application, the ProHeater can be used for high chamber or process temperatures of up to 150 °C. It is therefore suitable not only for basic preheating, but also for more demanding thermal processes in 3D printing environments.
- For heated 3D printer build chambers
- For enclosures and printer housings
- For filament drying boxes
- For controlled drying processes
- For defined annealing processes
- For engineering polymers and professional printing environments
📱 Operate directly on the device or through the web interface
The JESA ProHeater can be operated directly on the device. The integrated colour display and rotary encoder show important values and allow key settings to be adjusted locally.
A smartphone-optimised web interface is also available. Live values, settings, temperature trends and heating output can be monitored conveniently in a browser on a smartphone, tablet or computer.
- Colour display directly on the device
- Local operation via rotary encoder
- Operation possible without a permanent Wi-Fi connection
- Smartphone-optimised web interface
- Live values for temperature, setpoint and heating output
- 60-minute history for process monitoring
- Web interface currently available in German and English
- Firmware updates through the browser
🛡️ Monitoring and protection functions
The JESA ProHeater was developed not only for high temperatures, but also for controlled and monitored operation. The system separates the actual control temperature from the air outlet temperature, allowing the heating process to be monitored more precisely.
As the air outlet temperature approaches the configured limit, the heating output can be reduced. If the limit is exceeded, the heater can be switched off. An independent hardware safety temperature limiter (STB) is also planned as an additional protection layer.
- Dual-PT100 monitoring
- Separate air outlet temperature monitoring
- Soft limit for reducing the heating output
- Hard limit for shutdown when the configured maximum temperature is exceeded
- Shutdown in the event of a sensor fault
- Automatic fan run-on
- Restart after power loss is inhibited
- Additional hardware safety temperature limiter (STB) planned
🖨️ Optional integration into Klipper setups
The JESA ProHeater can optionally be integrated into Klipper-based 3D printing environments. This makes it particularly suitable for Mainsail or Fluidd setups in which temperature values, status information and process sequences are to be incorporated directly into the existing printing workflow.
- Optional Klipper integration
- Can be used as an additional temperature sensor
- Suitable for Mainsail and Fluidd environments
- Useful for automated printing and preheating processes
🧪 Expandable with optional sensors
Additional sensors can be added to the JESA ProHeater for extended applications. Optional humidity monitoring is particularly useful for drying boxes, as it provides additional information for assessing the drying process.
- Optional humidity sensor for drying applications
- Humidity-dependent heating operation possible
- Optional connection for VOC or air-quality sensors planned
- I²C interface for sensor extensions

Who is the JESA ProHeater designed for?
The JESA ProHeater is designed for users who want to apply heat deliberately in 3D printing rather than rely on improvised solutions. It is relevant for anyone who processes engineering materials, dries filament under controlled conditions, actively heats build chambers or wants to make thermal processes more repeatable.
The ProHeater is particularly suitable for:
- 3D printing users working with engineering materials such as ABS, ASA, PA, PC, PPA or PPS
- Heated build chambers and enclosures
- Filament drying boxes
- Print farms, workshops and development laboratories
- Prototyping, small-batch production and material testing
- Klipper users with Mainsail or Fluidd setups
🏗️ Planned production version and DIY version

The JESA ProHeater is currently still in the beta and final development phase. Functions, technical specifications and the scope of equipment may change before the final production version.
Frequently asked questions about our products
Quick answers: Here you will find information about our ProLine filaments, 3D printer upgrades and technical accessories.
1. Who are the products in the JESA shop intended for?
For anyone who wants to produce functional parts with 3D printing: brackets, fixtures, housings, spare parts, prototypes or technical upgrades for their own printer. The focus is not on decoration, but on parts that need to perform in real use.
2. What makes your products different from typical 3D printing accessories?
JESA sells products that come from our own practical experience. Our filaments, upgrades and accessories are designed to help you get more out of 3D printing — technically, reliably and transparently. It is not about as many gimmicks as possible, but about useful solutions for better print results.
3. Are the products only suitable for industrial users?
No. Although the products come from a technical and industrial environment, they are also suitable for ambitious private users. What matters is not whether you print privately or commercially, but whether you want to achieve strong, clean and functional results.
4. Does my 3D printer need to meet certain requirements?
That depends on the specific product. For technical filaments, the most important factors are nozzle temperature, bed temperature, build chamber, print surface and, for fiber-reinforced materials, a hardened nozzle. You can find the specific requirements directly on the respective product page.
5. Are technical data, print notes or profiles available?
Yes, where useful, we provide technical data, processing notes and in some cases slicer profiles. This is especially important for technical materials, because even the best material is of little use if temperature, drying, nozzle or print bed are not suitable.
