The ERMA FIRST BWTS FIT system has obtained a new type of USCG type approval which allows it to use a Filtrex filter.

To this end, the system’s current USCG Certificate has been amended to include the series of Filtrex filters (which is an alternate filter under the USCG approval) and now all models of ERMA FIRST BWTS FIT will have an option of the Filtrex or Filtersafe filter as per current IMO Type Approval.

“In our efforts to give more options to our clients and of course to expand our production capacity for covering the current and of course future demands, soon an application for a third filter will follow, said Mr Stampedakis, managing director of ERMA FIRST.

“Filtration is a necessary treatment stage which ensures environmental compliance despite the water quality and reduces significantly the wear and tear of the essential parts of the system.”

Filter options

As with the primary filter Filtersafe, testing results with the Filtrex configuration were successful and in compliance with USCG requirements, as assured by LR.

Tested in three water salinities, ERMA FIRST BWTS FIT is suitable for all types and sizes of vessels and special installation requirements in both newbuilds, as well as retrofit projects.

The company said that the system has been carefully designed, developed and engineered so as to ensure reliable operation in the most challenging natural water conditions.

The ERMA FIRST Amended Certificate 162.060/6/1 applies to the whole range of ERMA FIRST models 75-3000 with the two options of filters.
