VAROC Air Dynamometers

Portable Turboshaft Engine Testing in Any Climate

The VAROC family of air-brakes, V35, V35/85, and V250, provide an accurate, easy-to-use, easy-to-maintain, compact, lightweight, and highly reliable test capability to measure the performance of turboshaft engines ranging from 50 hp to 18,000 hp.

Our patented product design uses ambient air as the fluid medium, which provides significant advantages over other types of dynamometers, including water brakes. Some of the VAROC Air Dynamometer benefits are:

• Flexible installation in for use in fixed test-cell installations or mobile field applications
• No extensive support equipment required
• Operational in any climate, extreme heat, cold, arid or humid
• No potentially hazardous materials produced, so no need for contaminated water remediation, etc.
• Easy to operate & maintain

This video documents the Swedish Navy’s search for the best portable testing system for the aero derivative engines that power a critical part of their military infrastructure, stealth ships, and how Concepts NREC filled that need.
