Questions

Frequently Asked Questions

A standard residential or commercial AC system is designed around sensible load — lowering air temperature for human comfort. A Computer Room Air Conditioner (CRAC) or Computer Room Air Handler (CRAH) is engineered around a fundamentally different problem: high sensible heat density with precise humidity control, 24/7/365 runtime, and directional airflow matched to equipment layout. The critical differences come down to three engineering realities: Sensible Heat Ratio (SHR): Standard AC units run an SHR around 0.70–0.75, meaning they remove significant moisture from the air. Servers generate almost no latent (moisture) load — they generate dense, dry heat. A CRAC unit runs an SHR of 0.90–1.0, delivering near-total sensible cooling without over-drying the environment. Over-dehumidification causes static discharge that destroys hardware. Precision temperature and humidity control: CRAC units maintain tight tolerances — typically ±1°F and ±3% RH — against ASHRAE A1/A2 equipment specs. A comfort system swings far wider than that. Airflow design: CRAC units deliver high-volume, low-velocity airflow precisely directed at equipment intakes. Comfort systems move air for human occupancy patterns — not rack-level thermal management. Redundancy and runtime: Critical cooling infrastructure is engineered for N+1 or 2N redundancy with no planned downtime. A comfort system has no such design mandate. Installing a standard split system in a server room is a root-cause failure waiting to happen. We engineer CRAC and precision cooling solutions sized to your actual heat load — measured in kW per rack, not tonnage guessed from square footage.
