Martin Herbert - Engineering Director
With over 15 years of experience our Engineering Director, Martin Herbert, was part of the research group at The University of Bristol who were responsible for developing the original Ice Pigging concept. Led by professor Joe Quarini, the inventor of Ice Pigging, Martin and his colleagues took the process of Ice Pigging out of the laboratory and turned it into the useful, practical industrial tool which we use today.

Sean Ashton - Commercial Director
Our Commercial Director, Sean Ashton, has been instrumental in developing Ice Pigging and introducing our products and services into the manufacturing and industrial sectors that we work in today. Sean has an engineering background and has commercial and business development experience in many sectors, including water, chemical and maritime. Sean's experience and expertise has played a pivotal role in focusing Nivalis and therefore Ice Pigging in these manufacturing and industrial areas.
Sean leads the team in terms of Business Development and Business Strategy.

Tim Deans - Operations Director
Our Operations Director, Tim Deans, has been involved in Ice Pigging for over 15 years, was part of the team at the University of Bristol who worked on the original concept and is also a chartered Mechanical Engineer. Tim has had the opportunity to work in a range of different industries around the world, from Ice Pigging water mains in the middle of the night, to cleaning industrial pipes at cosmetics and pet food sites, owing to which Tim has a varied and extensive experience with the technology.

Dom Ash - Technical Director
Continuing our team’s in-depth knowledge of Ice Pigging technology, our CAD & Software Designer Dom Ash assisted in the design of Ice Pigging equipment at ADHQ Engineering. With a degree in Mechanical Engineering from the University of Bristol which lead to an EngD (Engineering Doctorate) in Ice Pigging, Dom also carried out a year of post doctoral research into Ice Pigging in the Food Industry. He then spent six years with SUEZ before bringing his wealth of knowledge to Nivalis-Tech Limited.

Wojciech Kocaja - Support Engineer
Before joining Nivalis, our support engineer Wojciech Kocaja worked as a Pharmaceutical Water Systems Matter Expert using Ice Pigging technology as an important step in biofilm remediation process on Pharma Water Systems. Wojciech now uses his in-depth knowledge of Ice Pigging technology across different sectors, including the pharmaceutical industry.

Christopher Walsh - Field Engineer
Having worked in engineering for all of his professional career, and as a former Royal Navy WO2 Artificer, our Field Engineer, Christopher Walsh, is able to put his real life experience to work supporting Nivalis customers across the globe. Chris's wealth of experience is utilised in supporting our customers with service and support, and, on the rare occasion that a system has a fault he is deployed to fault find and rectify. Chris also supports the team in system builds and therefore has a deep understanding of our Ice Pigging equipment.

Anna Janiszewska - Administrative support
Supporting the team from the office, Anna Janiszewska uses her background in the financial sector to support the engineering team with procurement and bookkeeping, as well as assisting the operations team with compliance and maintaining the quality management system.
