Using the TEWS does not require you to gather and transport any of the following to the wash site:

Requires no external power source
Needs no external water source (hose or bucket)
No external chemical supply containers (buckets or drum)

The "C" model supports all turbine aircraft and includes an onboard air compressor to close engine bleed bands.  The TEWS-C is fully approved by the U.S. Army.

The TEWS-D is a battery powered system with ample water and chemical (gas path, alcohol, and/or de-icing fluid) storage onboard. The TEWS system is designed to be pushed, driven or airlifted to the aircraft and placed into immediate operation.

Over Ocean Flights

The TEWS system is the perfect tool to use everytime flights are conducted over salt water. This Sikorsky S92 Helibus requires a daily Engine Fresh Water Wash with Hydro's TEWS-C in order to maintain peak performance when delivering crew members to an off-shore oil rig. Not only will the TEWS alliviate the salt build-up produced by over ocean flights, it will also increase the effeciency and power of the turbine engine by 3-10%!

The Hydropad provides an extra level of protection for the apron or maintenance area by keeping solvents and other chemicals off of the tarmac. Learn More About Hydropads Here
