Data Center Air Balancing & TAB Services

GENTAB balances and tests the cooling systems that keep data centers online. In a mission-critical facility, airflow is the difference between stable inlet temperatures and thermal events — and between efficient operation and wasted cooling energy. We measure and optimize how conditioned air is delivered to and removed from the IT load so equipment stays within its temperature envelope.

Our work covers CRAC and CRAH airflow balancing, raised-floor and overhead distribution verification, hot-aisle/cold-aisle and containment performance, and bypass and recirculation diagnosis. Many data centers run more cooling than they need simply because air is short-circuiting back to the units or leaking through unsealed pathways. By quantifying airflow at the source, the floor, and the rack, we help you deliver the right air to the right place and reclaim cooling capacity and energy in the process.

Every engagement is documented with measured airflow and temperature data, identified deficiencies, and practical recommendations. Whether you are commissioning a new white space, expanding capacity, or troubleshooting hot spots in an existing hall, our nationwide teams bring calibrated instrumentation and a methodical TAB approach to facilities where downtime is not an option and we coordinate carefully around live, energized environments.

CRAC / CRAH Balancing: Airflow measurement and balancing of cooling units so capacity is distributed to match the IT load, not wasted.

Hot/Cold Aisle Optimization: Aisle airflow verification to maintain consistent inlet temperatures and eliminate hot spots across rows.

Containment Verification: Testing of hot- and cold-aisle containment to confirm separation and prevent costly air mixing.

Bypass & Recirculation Diagnosis: Identification of short-circuiting and recirculation that waste cooling and threaten equipment temperatures.

Raised-Floor & Plenum Airflow: Verification of underfloor and overhead distribution to deliver design airflow where the load actually sits.

Cooling Performance Reporting: Documented airflow and temperature results with recommendations to reclaim capacity and improve efficiency.
