Computer room systems provide close-control cooling with tighter tolerances than standard comfort AC. They are engineered to manage both temperature and humidity under constant equipment loads.
Technology-heavy spaces generate concentrated and continuous heat loads. Dedicated cooling systems prevent overheating, maintain performance, and support operational reliability.
Maintaining consistent thermal conditions is critical for technology environments. Properly designed systems address redundancy, load density, and uptime requirements to reduce risk and ensure operational continuity.
Environmental Air Systems provides complete computer room and server room cooling services for commercial and institutional clients across New Jersey. Precision cooling systems require a higher level of technical care than standard commercial HVAC - we approach every computer room project with the attention to detail that mission-critical environments demand.
At Environmental Air Systems, we specialize in the design, installation, optimization, and ongoing service of commercial computer-room cooling systems. Whether you’re building a new data room, expanding an existing facility, or maintaining legacy equipment, our team ensures your cooling infrastructure meets performance, reliability and efficiency goals.

View All FAQsA CRAC unit is a precision cooling system specifically designed for technology environments. Unlike standard comfort AC with wider temperature tolerances, CRAC units maintain very tight temperature and humidity ranges, operate continuously under constant heat loads, and prioritize sensible cooling — removing heat rather than dehumidifying.
Standard commercial AC tolerates temperature swings and cycles on and off normally. Computer room cooling maintains temperature within a degree or two continuously, operates 24 hours a day 365 days a year, is sized for high sensible heat loads from electronic equipment, and typically includes redundant capacity so a single unit failure doesn't cause a cooling outage.
ASHRAE recommends inlet air temperatures at server equipment of 64.4°F to 80.6°F, with a practical operating target of 65°F to 75°F for most NJ facilities. Temperatures above 80°F increase equipment failure rates and thermal throttling.
ASHRAE recommends 20–80% relative humidity with a practical target of 40–55%. Too low creates static electricity risk. Too high creates condensation risk. At the Jersey Shore where summer outdoor humidity regularly exceeds 80%, proper humidity control in server rooms is particularly important.
Semi-annual service is the recommended standard for most mission-critical computer room cooling installations, spring and fall. Given continuous operation and zero-tolerance requirements, annual service intervals are generally not sufficient.
