The Globalstar ST-B18W is an 18 kW electric boiler typically used as an automatic steam generator for applications such as Moroccan baths, steam rooms, and skin treatments.

Key Features
Capacity: 18 kW power output, capable of producing approximately 30 kg of steam per hour.
Applications: Designed for removing dead skin layers and freshening/softening the skin in professional spa or bath environments.
Design: Often features a compact, automatic heating system that is energy efficient compared to fossil-fuel alternatives.
Operation: Generally near-silent with no carbon monoxide emissions since it is fully electric. 

Technical Considerations
Power Supply: Most 18 kW electric boilers require a three-phase 400V electrical supply due to the high power draw.
Safety: These units typically include integrated pressure relief and safety controls to manage steam production.
Efficiency: Electric boilers are often rated at 99–100% efficiency at the point of use, as nearly all electrical energy is converted directly into heat.
