Tech­no­logy

The acous­tic labor­at­ory in Bre­men en­ables us to carry out sys­tem tests in our own wall and pipe test stand.

Op­timal room con­di­tions and low flank­ing trans­mis­sions al­low sound meas­ure­ments even at heav­iest com­pon­ents, e. g. ship’s struc­ture, air ducts or pipes. Modi­fic­a­tions of the test area en­able meas­ure­ments of doors, in­dus­trial pan­els as well as pan­els of min­imum size.

The room char­ac­ter­ist­ics and the test meth­ods ap­plied meet the re­quire­ments of European reg­u­la­tions. The meas­ure­ment res­ults can be com­pared with those of ac­cred­ited in­sti­tutes, evid­ence of which provided by nu­mer­ous pro­jects.

Spe­ci­mens in­clud­ing their as­sembly are car­ried out in co­oper­a­tion with the nearby KAEFER work­shops, which means high flex­ib­il­ity and low costs.

In our ma­ter­ial test­ing labor­at­ory, we have nu­mer­ous pos­sib­il­it­ies for sup­port­ing en­gin­eers of the KAEFER Group early on in their tasks, by test­ing jointly de­veloped ideas un­der labor­at­ory and un­der crit­ical con­di­tions. Des­pite the name of the lab, we can test also small-scale in­su­la­tion sys­tems, like e. g. a glued samples of PUR us­ing dif­fer­ent ad­hes­ives.

In do­ing so, the ex­per­i­ence we have gathered in min­im­iz­ing risks of tech­nic­ally de­mand­ing solu­tions proves be­ne­fi­cial.

We al­ways ad­opt an out-of-the-box per­spect­ive – that is what we are here for. We look for al­tern­at­ives, in­teg­rate what is time-tested and de­velop new sys­tems in or­der to find the op­timal solu­tion for every task, profit­ing all the while from a large net­work of re­search fa­cil­it­ies, in­sti­tutes and other ma­ter­ial test­ing labor­at­or­ies.

We of­fer:

• Mechanical test under lab and critical conditions
• Determination of thermal conductivity
• Microscopic investigations
• Determination of open cell content
• Small-scale indicative test of the flame resistance (burning chamber – B2 Test)

And much more!

The KAEFER cli­mate test­ing labor­at­ory has a large range of equip­ment at its dis­posal, in­clud­ing a walk-in cli­matic cham­ber.

A tem­per­at­ure range from -75°C to 120°C is a unique fea­ture of the 15 m³ cham­ber. The walk-in cham­ber is ex­pand­ible 5 meters more in the length giv­ing us more space for long spe­ci­mens that do not need to be test at ex­treme con­di­tions.

The cli­matic cham­ber has its own air sup­ply which can be re­dir­ec­ted to closed spe­ci­mens in or­der to vary the in­ternal pres­sure, test­ing like that the mech­an­ical prop­er­ties sim­ul­tan­eously to the tem­per­at­ure and air hu­mid­ity.

This test rig was only made pos­sible by fit­ting the cli­matic cham­ber with an air pres­sure sys­tem put to­gether and con­figured by KAEFER en­gin­eers.

Be­side the cli­matic and pres­sure tests we can con­nect dif­fer­ent kind of sensors to the cli­matic cham­ber, like e. g.  move­ment trans­duct­ors.

All test para­met­ers and res­ults are re­cor­ded and stored in di­gital form. All meas­ure­ments are per­formed us­ing cal­ib­rated sensors, guar­an­tee­ing a high ac­cur­acy.

In case of small test spe­ci­mens, cli­matic cab­in­ets are avail­able:

• Climatic cabinets: Temperature from +10 °C to 100 °C / Air humidity from 10 % to 90 %
• Oven for conditioning: temperature up to 300 °C
• High temperature Oven: temperature up to 1.200 °C

In this test area we can in­vest­ig­ate in­su­la­tion sys­tems un­der nat­ural weather con­di­tions. Long-term test, in­stall­a­tion and per­form­ance tri­als are the fo­cus of the test rig, where com­plete in­su­la­tion sys­tems can be ana­lysed (coat­ing, in­su­la­tion ma­ter­ial, sub-struc­ture, clad­ding, glues and ad­hes­ives, mon­it­or­ing sys­tems and sensors).

• 30-meter pipe length
• Diameter DN 150 (168 mm)
• Internal pipe temperature until 180 °C
• Different insulation materials, coatings, and surface treatment
• Data acquisition of all relevant data
