Best Battery Selector – Increasing the Reliability of DC Power Systems

February 13, 2023February 10, 2023 by David Hurtado

Failing engine start or malfunctioning switchgear may be caused by the lack of a reliable DC power source. The use of redundant battery banks with a “best battery selector” is a practical approach to increasing the reliability of a DC power system. This article focuses on basic functions and features of best battery selectors.

Ultracapacitors – Adding Reliability to Emergency Generator Start Systems

August 26, 2018August 24, 2018 by David Hurtado

A “Failure to Start” is one of the top reasons for failures in emergency power systems, and the engine batteries are often found to be the culprit. But why do batteries fail? Can you mitigate the risk of failure? This article will identify typical failure modes, and describe a simple approach for designing additional reliability for the emergency generator’s start system.

From our clients!

I recently completed a fuel oil system design associated with (2) 2.5 MW emergency standby generators and worked closely with David for equipment design support associated with bulk storage tanks, day tanks, pump skids, filtration skids, fueling ports and controls. It was the first time that I worked with David and found the experience to be nothing short of excellent. I appreciated David's expertise and advice provided in selecting equipment and drilling down into details. David was always very responsive and went out of his way to make sure I had everything needed to complete my work and to answer all my questions during and after business hours. It's nice to work with folks that understand the equipment they represent and have a passion for the finer details. David has an excellent understanding of the equipment and was very enjoyable to work with. I look forward to working with David on our next project.

David has been an excellent asset for Fuel Oil system design. I am extremely grateful for all of his help!

Joshua Rose

I am a novice on fuel systems and needed help with a detail, David jumped in and gave me direction and assistance. Thanks David

Jeff Hawkins

I am writing just to highlight the great service and support I have always received from David Hurtado. His support has always been there in a technically sound base and in prompt manner.

From a consultant point of view his work has been exceptional. Have a great day…

I was very impressed the first time I dealt with David. I was recommended to David’s company by our Cummins sales representative, and David helped me thru my first fuel delivery system project for a Florida Assisted Living Facility. He does not just send general cut sheets of systems, … but details such as pump HP values, cables sizes, fuel piping sizes, sensor requirements, etc. I would recommend him highly to anyone struggling with fuel system design.

I was introduced to David by a coworker who insisted I speak with him for a fuel project design. It has been the best advice given to me. David is a fountain of knowledge and is more than willing to help and provide service. He has been an invaluable source of information for me.
