HB heating chamber
Thanks to perfected air circulation and insulation, the HB heating chamber offers fast heating times and high energy efficiency up to 120°C. With space for up to two IBCs or eight drums and access for hand pallet trucks or forklifts, it is extremely versatile. The modern PLC control ensures precise process regulation, while the DIBt-approved spill pallet guarantees safety and environmental friendliness.

Advantages
Fast heating
High air circulation accelerates the heating process in the heating chamber.
Optimal insulation
The labyrinth-like structure of the panels significantly reduces heat loss.
Uniform heat distribution
Uniform, targeted air flow around the containers.
Energy efficiency
Lower energy consumption thanks to reduced energy losses and low peak loads (7 kW).
Functional reliability
Optimal performance and operational safety in accordance with Machinery Directive 2006/42/EC.
Simulations
Optimal heat transfer
The Ansys® Fluent CFD simulation software shows that the air circulation in the HB 2700 heating chamber is optimally aligned:
The heated air is pressed evenly across the entire width of the chamber from the rear top through a slotted plate. Heat transfer is increased because the heat does not just touch the containers, but hits them head-on at high speed. The air curtain envelops the containers and flows around them. The adjacent figure shows the CFD simulation of the air velocity (m/s) in the HB 2700 heating chamber in front and side views.
Optimal insulation
If the door construction is not properly insulated, thermal bridges can form, facilitating heat transfer between the interior and exterior of the heating chamber.
Simulation of heat distribution in the door construction of the HB 2700 shows that the thermal conductivity decreases dramatically from the interior to the exterior. Centrally offset elongated holes significantly reduce heat transfer by extending the heat path in a labyrinth-like manner. At the same time, the size of the sheet metal passages is reduced. This reduces the thermal conductivity in the door area and achieves optimum insulation. The colour scale in the adjacent image refers to the temperature (°C).
Equipment
Maximum control and safety: Modern control and regulation technology ensures precise temperature control, high operating comfort and maximum safety – perfect for industrial applications with the most demanding requirements.
Precise temperature control: With the intelligent PLC control based on ELIWELL, the temperature remains constant at +/- 0.5 K exactly at the measuring sensor. The adjustable range from +15°C above ambient temperature to 120°C guarantees optimum conditions for your processes.
Intuitive touchscreen operation: The central 7" touch display allows you to control all functions intuitively and monitor temperature curves and system messages in real time.
Automatic shut-off: When the heating chamber door is opened, the fan and heating are automatically deactivated – for optimal personal safety and energy-efficient operation.
Extensive connectivity & monitoring: With a MODBUS interface, USB data output and analogue value transmission (4-20 mA), you are always optimally connected. All relevant data is available for complete documentation.
Robust design – safe and durable: The control cabinet is designed for temperatures up to 40°C and reliably protects the control system from external influences.
Clear signals for safety and control during operation
Our heating chamber is equipped with an intelligent LED signal system that provides clear status information at all times. Thanks to its clearly visible placement in the roof area, you can keep an eye on the operating status at all times.
Three-colour LED signal lights (IP 65) for immediate status display:
Green: Signals normal operation – everything is running according to plan.
Red: Reliably warns of malfunctions. An acoustic signal also sounds for immediate response.
Reliable overheating protection
Our heating chamber offers reliable protection against overheating thanks to the integrated safety temperature limiter (STL).
Automatic safety shut-off: The STL continuously monitors the heating process and permanently interrupts the energy supply as soon as the preset limit value is exceeded.
Safe protection for your products: Precise temperature monitoring reliably protects your products from critical overheating.
Manual release for maximum control: After a safety shutdown, a deliberate manual reset is required – for maximum safety and control.
Honey bees have the impressive ability to combine different methods to generate and use heat efficiently and precisely for the needs of the hive. Our innovation department has taken this combination of methods as a model to achieve the best possible efficiency for the HB Heating Chamber.
Worker bees generate heat by vibrating their flight muscles without moving their wings. This method is mainly used to warm the hive when outside temperatures are cold. The temperature is regulated very precisely by their collective behaviour, which supplies and distributes the exact amount of heat energy required. In addition, bees use various methods to achieve optimal thermal insulation.
The Heating Box generates heat using electricity, which can come from renewable energy sources. A spiral heating element that utilises the entire pipe diameter for air flow ensures even heating and optimal heat transfer. The warm air is pressed evenly from the rear top through a slotted plate so that it hits the containers at high speed from the front and flows completely around them. Heat regulation is controlled by a temperature sensor. The insulation of the heat chamber also contributes to energy efficiency. Together, these factors work collectively to achieve maximum efficiency and precision.
