Cleaning the interiour of container and tank wagon

Near­ly all de­posits in tank­ers, con­tain­ers and tank wa­g­ons can be re­moved by high-pres­sure wa­ter.

Con­ven­tio­n­al clean­ing of con­tain­ers and tanks of all types is in many cas­es very time con­sum­ing and the re­sults are not al­ways sat­is­fy­ing. Au­to­mat­ic high pres­sure clean­ing there­fore as­serts it­self more and more: A high pres­sure plunger pump press­es wa­ter through the noz­zles of the URA­CA tank clean­ing head TWK with a pres­sure up to 1,600 bar / 23,200 psi.

The wa­ter jet cuts through the de­posits and with its defined se­quence of mo­tion guar­an­tees sur­face cov­er­ing re­mo­val of th­ese dirt de­posits. In re­la­tion to the rules stip­u­lat­ed in the ATEX di­rec­tive, the tank clean­ing heads can be used in all ex-zones (ex­cept in min­ing). In fact, they can be used in ex­plo­sion en­dan­gered at­mo­spheres caused by gas­es, vapours, mists, and dust.

Clean­ing the in­side of tanks with high-pres­sure wa­ter is help­ful to the en­vi­ron­ment. It does not re­quire the use of chem­i­cals, me­chan­i­cal tools or boil­ing. The waste dis­pos­al of the ac­cu­mu­lat­ing clean­ing wa­ter is limit­ed to the se­pa­ra­tion of the cleaned off prod­ucts. Com­pared with con­ven­tio­n­al meth­ods, high-pres­sure clean­ing is char­ac­terised by con­sid­er­ab­ly short­er clean­ing times and a bet­ter clean­ing ef­fect.

The cor­rect po­si­tion­ing of the tank clean­ing head is es­sen­tial for op­ti­mal clean­ing. The po­si­tion­ing de­vices and reel sys­tems, which are in­di­vi­d­u­al­ly adapt­ed to the tank ge­ome­try, en­able the per­for­mance of a tank-spe­cif­ic clean­ing se­quence. Lance sys­tems serve the pur­pose of po­si­tion­ing the tank clean­ing head TWK. Th­ese are char­ac­terised by the fixed po­si­tion­ing of the tank clean­ing head in ex­act ex­ten­sion of the lance axis, both in ver­ti­cal and slant­ed mount­ing po­si­tion. The achiev­able stroke is 7 m plus.

The pres­sure-tight at­mo­sphere when clean­ing some chem­i­cals in a tank clean­ing con­tain­er helps to en­able "pro­cess in­te­grat­ed" clean­ing. The clean­ing pro­cess can be start­ed im­me­di­ate­ly af­ter drain­ing off the prod­uct and does not re­quire any pre­pa­ra­tions, i.e. clean­ing takes place within the pro­duc­tion at­mo­sphere. Be­sides the im­prove­ment of prod­uct qual­i­ty based on op­ti­mal clean­ing re­sults and low en­er­gy con­sump­tion due to the avoi­dance of thick de­posits, pro­duc­tion down­times are re­duced to a min­i­mum.

The re­al­i­sa­tion of in­di­vi­d­u­al cus­tomised clean­ing so­lu­tions en­ables quick and ef­fec­tive clean­ing. En­hanced pro­duc­tiv­i­ty and high­er qual­i­ty of the end prod­uct re­sult in short pay­back pe­ri­ods.
