Nordtec Maritime Services - Renovation of Charge Air Coolers, Freshwater Generator, Seals and Heat Exchangers

Nordtec Maritime Services ApS is a reputable company, founded in 1998. We carry out the renovation of air coolers, mechanical seals and tube and shell heat shell exchangers. We also offer remanufactured freshwater generators as well as a variety of ceramic products for several marine corrosion protection applications.

RENOVATION OF CHARGE AIR COOLERS

We clean and renovate all types of air coolers. All coolers will be cleaned chemically. The cleaning fluids are developed so that they do not harm the coolers. The air cooler end covers can be renovated with Nordtec ceramic materials and new anodes.

FRESHWATER GENERATORS

The following FWG types is available in stock: nearly all AFGU types of Atlas Denmark, Atlas Sasakura, Nirex / Alfa Laval JWP26 and JWP36. We can offer remanufactured fresh water generators on a service exchange basis. When we remanufacture a FWG we strip it totally down and put all parts except tube plates in a pyrolyses oven. In the pyrolyses process the items are heated up to 500ºC in 12h to get rid of the chlorites which are trapped in the steel.

When the items are out of the oven it is sandblasted to SA2½. If there is a hole in the casing the area is cut out and replaced with new plate - if the tube plates are bad they are replaced. All tubes in the heater and condenser are changed. All gaskets are replaced. All bolts are replaced, and the bolts in the condenser are replaced with stainless steel bolts.

After repair on the casing it is sandblasted again to SA2½. All small corrode areas are rebuilt with Nordtec Ceramic Rapid. The bottom is coated with three layers of Nordtec 2212 FDA (food grade coating), whilst the sides are applied with two layers of the same. The Nirex distiller JWP 36, JWP 26 and Atlas distiller of AFGU types are very frequent visitors to our workshop.

FRESHWATER GENERATOR SPARES

We deliver pumps, ejectors, plates and gaskets for the following types: Nirex and Alfa Laval JWP-26 / JWP-36. The Nirex plates are totally remanufactured, chemically cleaned, crack tested and provided with new gaskets. New gaskets can also be delivered directly from Nordtec on a day-to-day service. We are able to supply nearly all spares for Atlas Danmark and Sasakura.

MECHANICAL SEALS

We carry out the repair and sales of the most common and special mechanical seals, such as: FLEXIBOX, JOHN CRANE, NIPPON PILLAR, SEALOIL, BURGMAM, CYCLAM and PACIFIC.

TUBE AND SHELL HEAT EXCHANGERS

We are able to deliver tube and shell heat exchangers that range in size from the smallest to the largest. In cases where reconditioning is no longer an option, we can deliver new heat exchangers upon specification.
