Portable e-nail for water pieces
Quartz heating element with stable temperature output
Compatible with glass-to-glass connections
Powerful internal battery with USB-C pass-through

The G Pen Hyer is designed as a modular heating system that works directly with glass-on-glass water features. Instead of a traditional mouthpiece, this device uses a separate tank module , connected to the battery unit via a magnetic power cable.
The core of the system is the quartz heating element , housed in an aluminum tank housing. This design focuses on temperature stability, airflow, and material purity , without complex menus or apps. Operation is via three buttons and an LED interface , which keeps the device clear despite its versatility.

Modular tank structure with interchangeable tanks
Quartz chamber for consistent heat distribution
Magnetically coupled power cable for flexible placement
14mm glass adapter included as standard

The battery is integrated into an anodized aluminum housing and offers high capacity. Thanks to USB-C pass-through, the system remains operational while charging. All components are designed for quick installation and easy maintenance.
The Hyer is not a standalone device, but a building block within a glass setup, intended for those who work with water filtration and prefer a fixed installation point.

MATERIALS THAT MATTER
A desktop model is designed for stationary use and typically operates via mains power. As a result, size and mobility are less important, and the emphasis is instead on power, temperature control, and delivery systems such as a balloon or whip.
A whip is a flexible tube that connects directly to the device. A balloon system collects the heated air in a detachable balloon. Some devices support both systems. Please check each model to see what is included as standard.
Conduction heats via direct contact with the heated chamber. Convection uses heated air. A hybrid device combines both techniques. The heating system used is listed in the technical specifications.
The warm-up time varies significantly by model and set temperature. Some devices are ready for use quickly, while other systems require a few minutes to reach a stable temperature. Please consult the device specifications and manual.
Switch off the appliance, unplug it, and allow it to cool down completely. Only clean the removable parts according to the manual. Ensure that no liquid enters the electronic base and only replace parts once they are completely dry.
