How Dual PWM Steam Control Keeps Goehner’s SteamVex Output Steady
How Dual PWM supports steady Goehner’s SteamVex steam cleaner (SteamVex) output
Dual PWM helps SteamVex coordinate water delivery with heating power. One control manages water entering the flash-heating chamber while the other works with PID temperature feedback, supporting controlled 230°F nozzle steam and steady 50 PSI output across a cleaning session.
The customer benefit is consistent: three distinct steam levels, lower-moisture output, fewer output swings and precise light-touch start-stop control at the handle.

Explore SteamVexWhy heat and water must stay coordinated
Continuous steam follows a repeating sequence: water enters the heating area, the heater supplies energy, the water vaporizes and steam leaves through the nozzle. As one portion exits, the system must prepare the next.
SteamVex Dual PWM coordinates that rhythm. Pump-side control meters water delivery while heater-side control adjusts average power using temperature feedback. The goal is to keep incoming water aligned with the energy available for vaporization, supporting steady heat, pressure and steam volume.
What is PWM?
PWM stands for Pulse Width Modulation. It adjusts average output by changing how much of each rapid control cycle a component remains on—its duty cycle.
At a 20% duty cycle the component is active for about one-fifth of the cycle; at 50% it is active for about half; at 80% it is active for most of the cycle. That fine-grained timing lets a controller adjust average heater power or pump delivery without relying on a single all-or-nothing operating state.
How PWM coordinates heat and water
PWM gives a steam cleaner fine control over two variables that must stay coordinated: heating energy and incoming water. Heater control can increase average power when more energy is needed, then reduce it as the target range is reached. Pump control can meter water so delivery stays aligned with current vaporization capacity.
That coordination supports stable output, distinct steam levels and lower liquid-water entrainment through a continuous cleaning session.
What Dual PWM does inside SteamVex
SteamVex uses Dual PWM to coordinate two parts of the flash-heating process. Heater-side PWM works with PID temperature feedback to regulate average heating output. Pump-side PWM manages the average amount of water entering the heating chamber.
Together, the controls balance heat and water in real time so SteamVex can deliver three usable output levels while maintaining its 230°F nozzle-steam and steady 50 PSI operating specifications.
How water control supports low-moisture steam
When the heating chamber receives water at a rate matched to its current vaporization capacity, more of the output can leave as controlled low-moisture steam instead of unnecessary liquid droplets.
The complete SteamVex workflow then manages normal surface condensation with continuous movement, washable cloth bonnets and an immediate towel wipe.
How PID and Dual PWM work together
| Control element | Plain-English role | SteamVex benefit |
|---|---|---|
| PID temperature feedback | Compares the target range with measured temperature and calculates a response | Helps keep heating energy aligned with the working condition |
| Heater-side PWM | Changes average heater output through duty cycle | Supports sustained nozzle heat |
| Pump-side PWM | Changes average water delivery through duty cycle | Matches incoming water to flash-heating capacity |
| Three steam levels | Applies different output targets | Moves from light work to the strongest setting |
| Capacitive touch trigger | Starts and stops the requested steam output at the handle | Gentle touch-and-hold control without hard squeezing |
Why sustained output matters
A strong steam cleaner must maintain useful output after startup. SteamVex combines a published 230°F nozzle temperature with steady 50 PSI pressure, three steam levels and Dual PWM control so the system continues coordinating heat and water during the cleaning pass.
That sustained behavior is what lets the same machine move from light surface work to everyday buildup and then to its strongest output level.
Why does SteamVex describe its system as Dual PWM?
Dual PWM describes the two coordinated control paths inside SteamVex: one for average heater output and one for average water delivery. PID temperature feedback informs the heat side, while flash heating turns the metered water into steam on demand.
The architecture supports about 30-second startup, three steam levels, low-moisture output and steady 50 PSI performance in a compact household system.
How control engineering becomes a practical cleaning benefit
| Visible result | SteamVex control behind it | Customer benefit |
|---|---|---|
| About 30-second cold start | 1,800 W flash heating + coordinated control | Less waiting before the first pass |
| Three distinct steam levels | Heat and water targets change together | Output matches light, everyday or heavier buildup |
| Steady 50 PSI output | Balanced water delivery and vaporization | Consistent pressure through the cleaning route |
| 230°F nozzle steam | PID feedback + heater-side PWM | Focused heat at the point of work |
| Low-moisture delivery | Pump-side PWM aligned with heating capacity | Easier bonnet and towel pickup |
| Precise start-stop response | High-sensitivity capacitive touch trigger | Steam flows with a gentle touch and stops when released |
Control engineering matters because the customer can feel it in every setup, level change and cleaning pass.
Frequently asked questions
What does PWM mean in a steam cleaner?
PWM changes the active share of each rapid control cycle, adjusting the average output of a heater, pump or other actuator over time. In SteamVex, it helps coordinate heating energy and water delivery.
Are PWM and PID the same thing?
They perform different but complementary roles. PID calculates a response from temperature feedback; PWM is one way to apply that response by changing average heater or pump output through duty cycle.
How does Dual PWM support low-moisture output?
SteamVex Dual PWM supports low-moisture output by coordinating water delivery with flash-heating capacity. The practical result comes from the complete system: 1,800 W heating, temperature feedback, pump control, nozzle design, three levels and purpose-matched pickup.
How do 230°F and steady 50 PSI work together?
SteamVex publishes 230°F / 110°C at the nozzle and steady 50 PSI / 3.5 bar as separate operating specifications. Dual PWM helps the machine coordinate heat and water so both values contribute to a controlled, sustained cleaning pass.
Why SteamVex uses Dual PWM
SteamVex uses Dual PWM because stable steam depends on coordinated heat and water delivery. Heater-side control, pump-side control and PID temperature feedback work together to support fast startup, three steam levels, low-moisture delivery and steady 50 PSI output.
The advantage is experienced at the handle: focused steam that stays consistent through grease, grout, tracks, glass, fabric and auto-detail tasks, with light-touch start-stop control for every pass.

The value of Dual PWM is practical: it helps SteamVex balance water and heat so the nozzle delivers controlled steam through the jobs you repeat.
