How it works:

Ozone is generated and distributed automatically into the space
Sensors monitor air quality and concentration in real time
The system pauses when levels peak, then restarts when safe
Minimum manual cleaning required

Bacteria, virus, mold & odoor control for offices, hotels & healthcare facilities

Who is this for?

Offices & Corporate spaces

For office managers, HR and operations teams who want fresher air, fewer odor complaints and a more comfortable workplace.
Hotels & Serviced apartaments

For guest rooms, corridors, lobbies and back-of-house areas where air freshness directly affects guest experience.
Clinics & Healhcare facilities

For healthcare environments where hygiene, odor control and air-quality confidence matter every day.
Restaurants & Horeca spaces

For dining areas, kitchens, staff zones and high-traffic indoor spaces where odors and air freshness affect customer perception.

Different spaces. Same air-quality challenge.
Regardless of the environment, AC systems can circulate odors, bacteria, viruses and mold-related particles. GCES integrates with existing AC/HVAC infrastructure to provide controlled, monitored air-hygiene treatment — without AC modification.

The problem

Poor indoor air qualit y can be a silent saboteur, affecting comfort, health, and perception of your space. It often stems from multiple interconnected issues.

Stale air

Lack of adequate ventilation can lead to a build-up of CO2 and VOCs, making spaces feel stuffy and causing discomfort or even drowsiness.
AC-realated odors

Over time, AC systems can accumulate dust, debris, and moisture, leading to persistent musty or chemical smells that permeate the environment.
Mold-related smell

High humidity and condensation within air ducts create ideal breeding grounds for mold and mildew, emitting a distinct, earthy odoor and releasing spores.
Bacteria and viruses

We like to make people happy. We ask our clients about their birthday and prepare cool presents.
Complaints from staff, guests or visitors

Recurring feedback from staff, guests, or visitors about air quality issues indicates a systematic problem that requires a targeted solution.
Poor perception of cleanliness

Even if a space looks clean, unpleasant odors or a noticeable lack of freshness can create a negative impression, affecting guest or employee satisfaction.

How it works?

Install equipment
We install our equipment in the technical area (outside the AC unit).
Real-time sensors
Real-time sensors continuously measure ozone levels in occupied areas.
Controlled ozone delivery
Ozone is delivered in controlled, low concentrations through the air-conditioning airflow.
Automatic protection
If levels approach the set limit, the system pauses and restarts only when safe.
Day & night modes
Stronger treatment at night; ultra-low maintenance levels during the day (as needed).
The entire process runs automatically with built-in safety at every stage.

What you wiil notice

Freshener-feeling air
Fresher-feeling air and fewer odor complaints in shared indoor areas.
Reduces bacteria & viruses
Helps reduce bacteria, viruses and odors circulating through AC systems.
Works across the whole system
Reaches corners and hidden internal surfaces (not only where light can reach)
Addresses mold-realted odors
Helps address mold-related odoors by treating areas that manual cleaning often can't reach.
Configured to match your actual AC airflow conditions
Designed for real-world AC/HVAC conditions

Peace of mind

Monitoring dashboard

With charts and automatic alerts
Automated call-out

You don't need to chase anyone - our team is notified if anything deviates.
Safety-focused operation

Designed with sensor-controlled safety logic for occupied-space environments.

on-site support

Even with full automation, we still visit your facilities once a month with a checklist to confirm everything is running welll and that you are happy with the service.

Aerobic colonies before

CFU/50cm² — reduced to
undetectable levels after treatment
4.3 K

Mold count before

CFU/50cm² — reduced below
detectable treshhold post-GCES installation
< 10

All parameters after

Every microbial parameter fell below detectable threshold post treatment

Client feedback

AL MASAOOD LLC

"Now the odor is eliminated, and we have no more bacteria. To be sure about this we conducted laboratory testing of samples before installing and after installing the system.""
