Solutions
Where global manufacturers offer a catalog, ORRIS engineers a solution. Custom HVAC systems built for the most demanding and unusual environments in the world.
Built for the Impossible
Daikin, Carrier, and Trane ship from a catalog. ORRIS starts with your problem. Every unit is engineered from scratch to solve the exact challenge your environment presents.
What Global Giants
Cannot Offer
Daikin has 80,000 employees. Carrier ships to 180 countries. They excel at scale — but they cannot redesign a unit for your basement ceiling height, your salt-air coastal site, or your ISO Class 5 clean room. We can.
Fully Custom — Every Unit
No catalogs, no compromises. Every unit is engineered to your exact specifications — non-standard dimensions, unusual coil configurations, special materials. If it can be built, we build it.
In-House Engineering & R&D
A dedicated team of mechanical and electrical engineers drives continuous R&D. We develop solutions for emerging challenges before the market even recognizes them.
Speed & Inventory Readiness
Mission-critical projects cannot wait. Our procurement team maintains strategic inventory of components so we can respond to urgent requirements without supply chain delays.
International Quality, Local Agility
ISO 9001:2015 certified with DUNS 100 mark of excellence. We source only from ISO-certified global suppliers — yet respond with the flexibility of a local engineering partner.
Full Vertical Integration
Design, engineering, manufacturing, wiring, and commissioning all under one roof in Rishon LeZion. No subcontractors on critical components — full quality control, start to finish.
Direct Consultant Collaboration
ORRIS engineers work alongside MEP consultants and architects from the earliest design stage. We solve the problem at the blueprint — not after the concrete is poured.
