Client Testimonial
Pipeliner for Reheater Desuperheater (July 2012)
775 MW Combined Cycle Power Plant
Gulf Coast, USA
We had a short outage and needed a pipe liner for a reheater project. The attemporator was broken off and we needed expert recommendations for repairing the nozzle.
HRST, Inc. was just great. They really helped us out a lot. They sent us a new liner right away. We had several questions about fitting the liner and we needed several on-site modifications.
What impressed me was how helpful HRST, Inc. was throughout the entire process. All of our questions were answered immediately and we got all the help we needed to make this project work for us.
I would definitely recommend your company to any facility with a similar need. We certainly plan on working with your firm in the near future.
Steam Drum Tretrofit Mist Eliminator Product (May 2010)
Refinery Cogen Facility
California, USA
Our mist eliminator was in pretty sad shape so we called Darryl Nagel at HRST, Inc. Darryl was very responsive and had a quote produced and delivered within 48 hours.
Darryl is very good at listening carefully to our concerns and providing solutions that work for us.
The new mist eliminator was delivered in a timely fashion and we were able to install it without issue.
I am very comfortable recommending Darryl Nagel and HRST, Inc. to any company with a similar need. They have done outstanding work for us and we will certainly be using them in the future.

I worked with Kevin Morales to purchase some tube inserts from HRST, Inc.
We were delighted to discover that the installation process went smoothly for us thanks to input and advice from Kevin Morales.
We feel that the tube inserts we were sold were of excellent quality and met the needs for our facility quite nicely. I enjoyed working with Kevin Morales and look forward to using HRST, Inc. for our future needs.
