BUILDING
THE FUTURE
OF CLIMATE
ORRIS K.S. Industries Ltd. is Israel's leading manufacturer of custom-engineered climate solutions. Where global manufacturers offer catalogs, ORRIS engineers answers — designing and building HVAC systems from scratch for the most demanding environments: surgical theaters, ISO-class clean rooms, data centers, extreme climates, corrosive industrial sites, and military installations.
Founded in 1988 and headquartered in Rishon LeZion, ORRIS operates a fully vertically integrated facility — from mechanical design and coil manufacturing to electrical panel assembly, wiring, and on-site commissioning. With over 100 professionals and a dedicated R&D department, the company exports to 15+ countries and has accumulated over 30,000 installations worldwide.
Today, ORRIS is at the forefront of intelligent HVAC — integrating UV purification, probiotic air treatment, AI-assisted demand control, and drone-ready climate systems into a single, world-class manufacturing operation.

Innovation
From atmospheric water generation to UV-integrated HVAC and AI-assisted engineering — ORRIS develops tomorrow's climate solutions today, with a dedicated R&D department driving continuous breakthroughs.
Precision Engineering
Every unit is manufactured to exact specification. Non-standard dimensions, special coil configurations, corrosion-resistant materials, ultra-low noise — if your project demands it, we build it.
Healthy Air
Beyond cooling and heating — ORRIS integrates UV air purification (Sagol), probiotic air treatment (Envirobiotics), and demand-controlled ventilation (ECOIN) directly into its manufactured units.
