Working principle

Connect to three-phase industrial power supply (380V) or higher voltage (such as 10kV)
Water is heated by flowing through multiple sets of horizontally arranged electric heating tubes (resistance type) or electrode rods (electrode type).
Steam generation: Water is heated and vaporized inside a horizontal cylinder, and steam is collected and output at the upper part of the cylinder. The control system achieves precise steam pressure control by adjusting the number of heating group inputs (group start stop) or power.

Horizontal electric steam boilers have greater efficiency

The horizontal structure allows for the arrangement of more and longer electric heating tubes to meet greater industrial demands
Larger water capacity, longer service life, and higher stability
Easy to enter the interior of the cylinder for cleaning, descaling, and replacing the heating tube
Zero emissions, high safety, fully automatic, nearly 100% thermal efficiency, easy installation
Easy to design for high-voltage power supply, reducing line current and minimizing line losses.

Suitable for industrial scenarios that require clean steam, convenient electricity usage, and high demand

Clean production industries: pharmaceuticals (extraction, sterilization), food and beverage, biotechnology, electronics industry (pure steam).
Areas with special safety requirements: chemical explosion-proof zones, basements, and densely populated comprehensive buildings.
As the main or backup steam source: in environmentally controlled areas, or in centralized heating stations and industrial production lines that utilize cheap valley electricity.

Comparative dimension	Horizontal electric steam boiler	Vertical electric steam boiler
Structure and Layout	Horizontal arrangement, with a large diameter and long length of the cylinder, occupying a large area but with a relatively low height	Vertically arranged, occupying a small area but with a high height, requiring a clear height for the space
Capacity Range	Big. Commonly ranging from 0.5 to 10 t/h, larger sizes can be achieved	Small. Commonly ≤ 1 t/h, mostly below 2 t/h
Water capacity and stability	Large water capacity, high thermal inertia, more stable steam pressure and load	The water capacity is relatively small, and the start stop and load response are fast, but the pressure fluctuation is relatively obvious
Power Supply and Power	Easy to undertake high-power, high-voltage (10kV) designs, suitable for large-scale projects.	Mostly for small and medium power (≤ 720kW), supplied with 380V normal pressure power.
Application positioning	Industrial grade main or backup steam source, used for continuous production with high demand.	Small/distributed steam points, laboratories, and backup supplementary heat sources.
