The E-z̈o solution
E-z̈o is an intense pulsed light disinfection solution that is deconstructed, modular and integrable. Several optical blocks are distributed around the room to treat every zone and remove shadowing effects, where a mobile device reaches its limits.
Understanding the name
The number after E-z̈o indicates the number of optical blocks in the installation.
Every configuration is designed for a specific application: E-z̈o is never installed identically from one site to another.
The starting point
Some configurations cannot be treated by a mobile device placed in the middle of the room. E-z̈o was developed precisely to answer those cases.
Shadowing effect
1 blockWith a single block, part of the room stays in the shade. Multiplying and distributing the optical blocks removes unexposed zones.
Configuration 1 / 4
Broken geometry: the optical blocks are distributed along the walls to cover both legs.
A broken geometry creates blind angles that a single source never reaches.
Airlock for transferring materials or packaging accessories, to be treated in flow.
Restricted Access Barrier System: closed enclosure, restricted access, constrained volume.
Same logic: the light source must be installed inside the barrier.
The answer
A direct consequence: the solution must be designed and adapted to each application, which involves a study phase and, where needed, R&D.
The machine is split into organs: optical blocks, power unit, control interface. Each one is installed where it is useful.
From 1 to 4 optical blocks and beyond: quantity and orientation are dictated by the load and the geometry to be treated.
The blocks are recessed into the walls of the cleanroom, airlock, RABS or isolator. No floor footprint.
The disinfection cycle
From safety condition checks to load release, the cycle runs with no manual intervention: every step is controlled, recorded and traceable.
Before any pulse, the system checks that accesses are closed, that no one is in the zone and that the safety devices are operational. No cycle starts if a condition is not met.
The operator selects the recipe and starts the cycle from the HMI. Program, user and timestamp are recorded in the audit trail.
The optical blocks deliver intense pulsed light flashes according to the qualified parameters: energy, number of pulses and treatment sequence.
The system checks that the achieved parameters conform, closes the cycle and authorizes the load to be released. The report is available immediately.
Integrating a custom IPL system means adapting an existing solution to the site's real constraints (architecture, flows, electrical and safety requirements) while guaranteeing a 3 to 6 log reduction.
Specifications
Round table with the client's HSE, quality assurance and new works departments, together with the Biopulz engineering office. Every requirement collected goes into the specifications.
Follow-up
Regular reviews with all stakeholders: development progress, site constraints and discussions on the practical integration of E-z̈o into existing rooms.
Documentation
Installation qualification and operational qualification protocols are drafted, shared and approved with the client before any work on site.
Installation
Optical blocks fitted into the walls, power unit in the technical room and control panel in the clean zone, with no structural work.
IQ / OQ
IQ: installation check, equipment conformity and documentation. OQ: functional tests, operational parameter checks and verification of results.
PQ
PQ confirms the 3 to 6 log reduction on the Geobacillus stearothermophilus model strain, under the site's real operating conditions.
Real-world case
After the six steps, this is what a delivered installation looks like: a 5 × 5 × 3 m pharmaceutical cleanroom, four optical blocks integrated into the walls, the power unit in the technical room and the control panel outside the treated zone.

Control panel
The number after E-z̈o corresponds to the number of optical blocks needed to disinfect the loads encountered. Other configurations and other shapes are possible: a complete cleanroom, a transfer airlock, a RABS or an isolator.
The right choice
The choice mainly depends on what you want to disinfect and on the layout of the environment to be treated. Both solutions rely on the same intense pulsed light technology.
