HOW CAN WE ASSIST YOU?
HELS, your manufacturer for high-quality ball float steam traps
Our ball float steam traps are particularly suitable for applications where condensate needs to be removed continuously. Thanks to their automatic operation, they are able to process both small and large quantities of condensate. Changes in pressure or temperature hardly affect the performance of the ball float steam trap, making it ideal for a wide range of industrial processes.
Steam trap with float
Steam traps with a float are mechanical components that work according to the difference in density between steam and water. A float reacts to the condensate level and opens or closes the valve to drain the condensate. As soon as the condensate reaches the trap, the float rises and the valve opens, efficiently discharging excess condensate.
Steam trap with ball float
Float steam traps are durable and reliable, as their robust design enables them to withstand high loads and complex systems. With the right installation and regular maintenance, they ensure a long service life and minimize downtimes, which significantly increases the efficiency of steam systems.
Free-float steam trap
As an experienced float steam trap manufacturer, HELS offers high-quality solutions for efficient condensate drainage in steam systems. With over 20 years of industry experience, HELS develops robust and reliable products specifically designed for industrial applications. Our float steam traps guarantee continuous drainage of condensate and thus contribute to the optimization of heating systems, heat exchangers and other processes.
Free-float steam traps are an advanced version of float steam traps in which a freely movable float ball controls the valve. This design ensures particularly reliable and low-wear operation, as no additional mechanics are required to open and close the valve. The float reacts directly to the condensate level and thus ensures continuous, delay-free drainage.
Thanks to the free rotation of the float ball, wear on the valve seat is reduced, which significantly extends the service life of the trap. These steam traps offer high efficiency with minimal maintenance and are ideal for use in steam systems with large condensate volumes or pressure fluctuations.

LET US ANSWER THE FREQUENTLY ASKED QUESTIONS
How does a float steam trap work with pressure fluctuations?
Float traps react to the condensate level and not directly to pressure changes, which is why they work reliably even in the event of sudden pressure fluctuations. The float opens and closes the valve independently of the pressure as long as the condensate level rises or falls.
What advantages does a free-float steam trap offer over conventional traps?
Free-float steam traps offer low-wear operation by dispensing with mechanical controls. The float ball can rotate freely, which extends the service life and ensures a vapor-tight seal.
When should a float steam trap be serviced?
Regular maintenance depends on the operating environment, but should be carried out at least once a year. This involves checking the float for wear, cleaning the valve and testing it for leaks to prevent faults in the condensate drainage.
Why are ball float steam traps insensitive to water hammers?
The free float ball prevents mechanical damage caused by water hammers, as it adapts flexibly to the flow conditions and thus minimizes the load on the valve system.
How does water hammer affect the performance of a float steam trap?
Water hammers can damage the float and impair the function of the trap. It is recommended to install protective measures such as dirt traps and shock absorbers to prevent damage caused by sudden pressure peaks.
Which areas of application are particularly suitable for float steam traps?
Float traps are particularly suitable for systems with a constant condensate flow, such as heat exchangers, heating batteries and drying systems. They offer high reliability in applications where fast and continuous condensate drainage is required.
