DAB E.Sybox Mini 3 electronic pressurisation system — compact 1.1 HP, ultra-low 45 dB, 7.5 bar

The DAB E.Sybox Mini 3 is a compact, all-in-one electronic pressurisation system that maintains steady household water pressure with low noise and energy-saving VFD control.

The E.Sybox Mini 3 combines pump, electronics, sensors and a small expansion tank into a single unit sized for tight spaces. Built for single-residence supply, it delivers configurable pressure between 15–80 psi (up to 7.5 bar) and up to 80 l/min flow, while running quietly at about 45 dB(A). Its plug-and-play design removes the need for extra external components, and a high-resolution 2.7" x 1.5" LCD gives clear system feedback for simple setup and monitoring.

How does the E.Sybox Mini 3 keep water pressure steady throughout a home?

The unit uses built-in pressure and flow sensors plus an electronic variable-frequency drive (VFD) to adjust pump speed automatically. When demand rises, the pump increases speed to maintain selected pressure; when demand drops, it slows to save energy. This delivers consistent taps and showers without the cycling typical of traditional pressure tanks.

• Adjustable pressure range: 15–80 psi (up to 7.5 bar)
• Automatic VFD control for continuous regulation
• Integrated pressure and flow sensors for real-time response
• Built-in check valve and expansion tank for reliable operation

How energy-efficient and quiet is this pressurisation system?

Thanks to VFD technology the pump only uses the power needed to meet demand, reducing electrical consumption compared to fixed-speed pumps. The unit is rated at about 45 dB(A), making it noticeably quieter than standard residential pumps, which helps when installed near living spaces. Lower noise and soft start/stop behavior also reduce mechanical stress on the system.

• Variable-frequency drive minimizes wasted energy
• Ultra-low noise operation (~45 dB(A)) for discreet placement
• Soft start/stop extends component life and reduces vibrations

What do I need to install the E.Sybox Mini 3, and where can it go?

Installation is straightforward because the E.Sybox Mini 3 ships with the pump, electronics, pressure sensors, expansion tank and check valve pre-assembled. No separate external pressure tank or additional control box is required, so the unit can be mounted vertically or horizontally to fit confined spaces. Standard plumbing and electrical connections are still needed, and orientation guidance should be followed to maintain proper ventilation.

• Comes pre-fitted with expansion tank and check valve—no extra parts required
• Mount vertically or horizontally for installation flexibility
• Requires standard mains connection and plumbing tie-in at inlet/outlet

What are the performance limits and recommended uses of this system?

The E.Sybox Mini 3 is optimized for single-residence supply and light commercial points where compact size and quiet operation matter. It delivers up to 80 l/min flow and a maximum pressure of 7.5 bar (approximately 108 psi), though recommended operation for household comfort lies within the adjustable 15–80 psi range. Use it for potable water supply, household fixtures, and garden irrigation where flow and pressure demands match the unit’s capabilities.

• Maximum flow: 80 l/min; peak pressure: 7.5 bar
• Ideal for single-family homes, apartments, and small irrigation
• Suitable for potable water and general household use

Who is this for? The DAB E.Sybox Mini 3 suits homeowners and installers needing a compact, low-noise, energy-conscious solution to stabilize domestic water pressure without adding large tanks or external control gear. It’s especially useful where space is limited or where installing a conventional pressure vessel would be impractical. Choose this unit if you want clear on-board controls, automatic operation, and a tidy single-package installation that supports showers, taps and light outdoor watering with consistent pressure.
