Bachiller has successfully delivered a new 3,770 m² Falling Film Evaporator to a German engineering company specialized in the design and construction of chemical projects and plants.

This piece of equipment is part of a bigger set composed of the heat exchanger, a 42 m³ Centrifugal Separator, a 64 m² Surface Condenser and several Vapour Ducts. All made of 316L Stainless Steel.

The loading process was really exciting due to the high length of the piece of equipment that required the support of an extra crane and exceptional long transport.

Bachiller designs and manufactures all kinds of tailor-made shell and tube heat exchangers, according to the main international mechanical design codes, using the ultimate design software and according to the particular specifications of the client.

The most common applications are aftercoolers, boilers, catalyst reactors, concentrators, condensers, coolers, double sheet exchangers, evaporators NH3, exchangers for liquids – gas, heaters, preheaters, reboilers, reflux condensers, sublimators, vacuum evaporators and vaporizers.

Our construction materials are austenitic stainless steels, super austenitic stainless steels, duplex and super duplex stainless steels, nickel alloys and superalloys, titanium and cladding.

We are delivering, to a well-known chemical company in the Netherlands, a Gr.7 Titanium reactor of 53 m³ with a three-shaft agitator.

Titanium grade 7 is the most resistant to corrosion of all titanium alloys currently available. This grade is especially suitable for applications that require resistance to general corrosion and resistance to localized corrosion in cracks. It also exhibits good welding and forming characteristics as well as good overall strength.
