Guardian Series Products are selected to your design conditions — entering water temperature, 
airflow, static and sensible load. Curves below are drawn from delivered project selections; 
certified selections are issued per project from factory coil and fan software.

≈1.0 SHR — sensible cooling for the data hall. 
Guardian Products are selected for sensible-heat-ratio  1.0 at data center design conditions — near-zero latent, 
with humidity handled by the facility DOAS. Capacity, airflow and approach are tuned to your EWT and 
supply-air setpoint.
