Mef express tube bundle puller is the quick hooking version of the already existing Mef model. It has been entirely designed and manufactured by Maus Italia for maintenance of heat exchangers tube bundles in petrolchemical plants.
The hydraulic hooking of tube plate makes it possible to quickly inisert and pull out tube bundles when refineries are at a shutdown with a consequent work time reduction.The great solidity and sturdness of the structure as well as the innovative improvements make this machine extremely reliable.
Mef express puller is proposed in different standard dimensions according to weight, length and diameter of the tube bundles. A portable console enables the remote control of all the operations with consequent reduction in the personnel and increase in the final safety margins. In the diesel version a console with wireless remote control is available. It is supplied with diesel or pneumatic motorization.

This special version of the Mef espress unit has been produced to meet the need for extraction of tube bundles on petroleum platforms and installations at sea on large vessels known as FPSO.
The machine consists of a Mef espress NAVY operative part, produced for this purpose following most rigid standards concerning shipbuilding.
There are many similarities with the Mef espress ON SHORE as a rapid extraction system, however it is equipped with a special device that blocks any oscillations of the bundle due to sea swell. It is very compact and light, suitable for handling in small spaces, powered by a mobile power unit called Van Motor NAVY.In view of the unusual nature of the
off-shore application, the dimensional details of the Mef espress NAVY are based on the design specifications of the installation provided by the final client or engineer in charge of the project in a spirit of the closest collaboration.

Mef mobil tube bundle puller, designed for cases of difficult access, is completely self-sufficient, as is presented as a global solution in petrochemical plants for extraction of tube bundles.
Tested rapid quick-hooking system Mef express is used for extraction and insertion of the bundle. Mef mobil puller operates autonomously without assistance of a crane for positioning and hoisting or trucks for
transport to the tube bundle maintenance area after extraction.
It is solid, robust and stable and autonomously raises to a height of 4,2 m (166”) enabling a rapid and precise approach to heat exchanger.
The use of portable remote control (wireless also available), can control all operations, leading to inevitable reduction of personnel and increasing final safety margins. Mef mobil puller is proposed in two sizes, differentiating in weight, length and diameter of tube bundle to pull out. The operation of inserting tube bundle after maintenance
also becomes extremely rapid and precise thus guaranteeing reduction in plant stopping times.

Mef truck, thanks to original project of the telescopic rotating column, allows quick pulling/inserting of bundle.
Once truck is positioned, it is easy and quick to lift extractor and to proceed with extraction.
This system is particularly advised for maintenance's companies which operate continuously in petrochemical plant field.
