Question 1

What is a custom HVAC system?

Accepted Answer

A custom HVAC system is a heating, ventilation, and air conditioning solution engineered from the ground up to meet the specific requirements of a particular environment — rather than being selected from a standard product catalog. ORRIS has been designing and manufacturing custom HVAC systems since 1988 for surgical theaters, clean rooms, data centers, military installations, and industrial facilities.

Question 2

Why choose a custom HVAC manufacturer over off-the-shelf systems?

Accepted Answer

Off-the-shelf HVAC systems are designed for average conditions. Custom HVAC systems are engineered for exact airflow, temperature, humidity, and filtration requirements — critical for clean rooms, surgical theaters, data centers, and military applications where standard systems cannot meet the specification. ORRIS builds every system to the project's precise demands.

Question 3

Does ORRIS manufacture custom HVAC systems in Israel?

Accepted Answer

Yes. ORRIS K.S. Industries Ltd. is Israel's leading custom HVAC manufacturer, based in Rishon LeZion. Since 1988, ORRIS has delivered over 30,000 custom-engineered HVAC installations across 15+ countries, serving healthcare, pharmaceutical, data center, military, and industrial sectors with ISO 9001:2015 certified manufacturing.

Question 4

What environments require custom HVAC solutions?

Accepted Answer

Custom HVAC solutions are essential for environments with strict or unusual requirements: surgical theaters, pharmaceutical clean rooms, data centers, wine cellars, mobile units, corrosive environments, extreme climates, server rooms, and military/drone systems. ORRIS engineers custom climate systems for all of these applications.
