Who HS Ultra?

Why Hospitality Disinfection Matters

Hotels, resorts, cruise ships, and event spaces are high-traffic environments where pathogens can spread quickly. Routine cleaning alone isn’t enough to protect guests and staff from viruses, bacteria, mold, and allergens. HS Ultra’s advanced disinfection solutions—UV-C systems, gaseous ozone fumigation, and aqueous ozone applications—provide comprehensive pathogen control, ensuring both surfaces and airspaces are sanitized effectively. Our chemical-free methods safeguard the health of your guests while protecting sensitive surfaces and equipment from harsh chemicals, giving hospitality operators peace of mind.

Our Advanced Disinfection Methods

HS Ultra combines multiple technologies to deliver unmatched hygiene results. UV-C disinfection works silently in the background or during off-hours, sterilizing air and surfaces in occupied or sensitive spaces. Gaseous ozone fumigation provides a contact-free deep clean in unoccupied rooms or high-risk areas, eliminating mold, bacteria, viruses, and biofilms in less than 24 hours. Aqueous ozone is ideal for daily washdowns, mopping, and fogging, replacing harsh chemical sanitizers with a food-safe, residue-free solution. Together, these methods create a layered defense that protects guests, staff, and the property while maintaining operational efficiency.

Custom Consulting & Installations

Our team works closely with your operations, safety, or facilities team to develop a tailored disinfection plan based on your goals, pathogen risks, and compliance needs. Whether you’re managing food production, patient care, or high-traffic public buildings, we design systems that integrate seamlessly and deliver measurable microbial reduction.

UV-C Air & Surface Disinfection

Our high-output UV-C systems are engineered to disinfect air and surfaces in a single pass—making them ideal for HVAC retrofits, production lines, and patient care zones. Designed for performance and safety, these systems continuously reduce pathogens without the use of chemicals, downtime, or labor-intensive processes.

Aqueous Ozone Applications

Harness the power of Stabilized Aqueous Ozone (SAO)—a safe, non-toxic cleaning solution ideal for daily disinfection. Unlike conventional aqueous ozone, our SAO systems maintain potency longer, making them reliable for food contact surfaces, toys, medical equipment, and more. As authorized Tersano distributors, we exclusively use stabilized solutions that meet high standards for safety and performance.

Gaseous Ozone Fumigation

Our ozone gas treatments saturate the airspace and reach deep into HVAC ducts, equipment, and porous surfaces—destroying mold, bacteria, and viruses at the molecular level. Ideal for deep resets in food plants, labs, animal care, or buildings with persistent odor or contamination issues.
