Operating Principle

Diving equipment for construction machines.

Ba­si­cal­ly, a com­pres­sed air sys­tem (ADLA) for con­struc­tion ma­chi­nes can be com­pa­red to di­ving equip­ment.

The ope­ra­tor ca­bin is ful­ly in­de­pen­dent from the sur­roun­ding at­mo­s­phe­re. The bre­a­thing air is sup­p­lied in the form of com­pres­sed air stored in on-board tanks. This gua­ran­tees the health and sur­vi­val of your em­ployees and al­lows working safe­ly even in hos­ti­le en­vi­ron­ments.


Compressed air:
Oxygen in compressed form

The sup­p­ly of bre­a­thing air is stored in com­pres­sed air tanks. For this pur­po­se, the con­struc­tion ma­chi­ne is usual­ly equip­ped with 4 steel bott­les with a vo­lu­me of 50 li­ters each. They con­tain oxy­gen in com­pres­sed form wich is fed into the pres­su­ri­zed ca­bin via an Air­box. The Air­box in­clu­des all re­qui­red val­ves, as well as the pres­su­re re­gu­la­tor to re­du­ce the com­pres­sed air from appx 300 bar to a le­vel clo­se to am­bi­ent pres­su­re.

Adaptive air control:
Innovation for prolonged availability

Ad­ap­ti­ve Air Con­trol from SEKA is an in­tel­li­gent bre­a­thing air con­trol unit de­si­gned for the de­mand-re­la­ted ad­just­ment of the air flow. It al­ways di­rects ex­act­ly the amount of air into the ca­bin that is nee­ded to pro­vi­de the re­qui­red bre­a­thing air qua­li­ty at the in­ten­ded pres­su­re. This sys­tem is able to ac­tual­ly dou­ble the avail­a­bi­li­ty of the con­struc­tion ma­chi­ne.

Cost reduction:
Intelligent compressor design

The com­bi­na­ti­on of the SEKA Ad­ap­ti­ve Air Con­trol sys­tem with an in­tel­li­gent com­pres­sor de­sign re­sults in con­sider­ab­ly lo­wer in­vest­ments for the over­all sys­tem. If a con­struc­tion ma­chi­ne nee­ds to be ope­ra­ted in com­bi­na­ti­on with a com­pres­sed air sys­tem only for spe­ci­fic pro­jects, a cost-ef­fec­tive op­ti­on is ren­ting the com­pres­sor sta­ti­on tem­pora­ri­ly.
