Simplex-Turbulo supports the marine, offshore, chemical, power generation, water, and railway industries. We’re a dynamic, growing and independent company supplying marine components, diesel engine spares, and service for diesel engines, for sterntube seals, and for propulsion systems.

Our aim is to keep our customers’ engines and vessels working at maximum efficiency and with minimum downtime.

Our strategy for achieving this is to:

develop close relationships with our customers so that we can work together to ensure repairs are carried out seamlessly and fast.
invest heavily in stock, and in computer systems, in order to cut down delivery times and enable us to offer better value.
cultivate our technical expertise, training our own engineers and liaising with the research departments of our suppliers.
constantly reassess the quality both of the components we supply (to ensure longer time between overhaul) and of the service we provide. We aim, at all times, to be professional and honest with our customers.

Simplex is a well-established and respected independent company which has been supporting the marine and power industries for more than seventy years, supplying marine components and diesel engine spares. We are quality approved (ISO9001:2008) and have an excellent credit rating, along with reassuring insurance, and warranties.
