EC fan array retrofit using Ziehl-Abegg EC fans inside a hospital air handling unit in New York City.

Ziehl-Abegg North America Spotlights GRR Cooling Experts for Hospital Retrofit Work

Nov 20, 2025

When one of the world’s leading fan and motor manufacturers highlights your field work, it matters.

Ziehl Abegg North America recently featured one of our hospital retrofit projects on their official channels. This is a rare and meaningful recognition from a global OEM known for engineering precision and strict quality standards.

Their post highlighted our installation of Ziehl Abegg EC fan technology inside an active hospital environment in New York City. The project required the removal of failing equipment, installation of new EC modules, performance validation, and full restoration of stable airflow. All work was completed under live hospital conditions with zero disruption to operations.

When a manufacturer of Ziehl Abegg’s caliber publicly references a contractor’s work, it confirms two points:

  1. GRR delivers retrofit projects at a standard trusted by top-tier OEMs.

  2. Our hospital and critical environment installations are visible and validated at the industry level.

This recognition is not simply a project mention. It is a signal of technical trust.
