Variable Primary Pumping Configuration

A variable primary pumping configuration was utilized for this project. Compared to alternative pumping configurations, variable primary configurations are advantageous because they have lower up-front costs and can conserve energy after installation.

Electrical Requirements For Medical Facilities

Hospitals have unique and specific code requirements for the design and installation of the electrical distribution system throughout the facility. From redundant grounding and segregated power distribution systems, specific fire alarm requirements, to nurse call systems, we have the needed expertise and knowledge to cover these topics and the many others required for medical facilities
