Steinhardt DilliGent® CareTec

Lubricant coolant maintenance
- without chemicals -
safe, efficient, durable

The Challenge

Lubri­cant coolants are large­ly used in cut­ting pro­duc­tion. The addi­tion of bio­cides or dis­in­fec­tants is fre­quent­ly nec­es­sary in order to main­tain the hygiene of the coolants. By law, a risk analy­sis is required lay­ing down the pro­tec­tive mea­sures which must be tak­en to safe­guard work process­es and health. Good grade lubri­cant is the key to prob­lem-free and supe­ri­or qual­i­ty man­u­fac­tur­ing process­es. Waste dis­pos­al is car­ried out by spe­cial­ists and is a sig­nif­i­cant cost fac­tor. Neg­li­gent  han­dling of lubri­cant coolants can result in major risks for pro­duc­tion, health and the environment.

The Solution

The Stein­hardt Dil­li­Gent® CareTec uses inno­v­a­tive hydro-mechan­i­cal tech­nol­o­gy for the effec­tive, env­i­ron-men­tal­ly and health-friend­ly treat­ment of lubri­cant coolants. Pol­lu­tion is treat­ed reli­ably and re-con­t­a­m­i­na­tion pre­vent­ed. Long years of expe­ri­ence and exper­tise in the field of water treat­ment have been invest­ed in the devel­op­ment and appli­ca­tion of Dil­li­Gent® cav­i­ta­tion tech­nol­o­gy. The com­pact units are inte­grat­ed into exist­ing machin­ery or the cen­tral plant and oper­ate ful­ly auto­mat­i­cal­ly with no addi­tion­al chemicals.

The Way

The Dil­li­Gent® CareTec ‘s oper­a­tion is based on phys­i­cal active prin­ci­ples and is chem­i­cal-free. A par­tial flow of coolant pass­es through the Dil­li­Gent® CareTec unit for treat­ment. Bac­te­ria are mechan­i­cal­ly destroyed and removed from the water by oxi­da­tion, achiev­ing an over­all improve­ment in the qual­i­ty of the lubri­cant coolant. An appro­pri­ate fil­tra­tion process fur­ther increas­es the degree of impu­ri­ty removal. Re-con­t­a­m­i­na­tion is effec­tive­ly pre­vent­ed and the ser­vice life of the lubri­cant coolants sig­nif­i­cant­ly length­ened. The CARETEC unit can be exact­ly adapt­ed to exist­ing sys­tem vol­umes and is suit­able for either per­ma­nent or inter­mit­tent operation.
