IMB Advanced Design

With >700 units in service, IMB built LABLEX® units represent >50% of the world's installed database. Advanced design eliminates the large channel cover flange and bolting associated with conventional high pressure heat exchanger designs to deliver significant reductions in size and weight.

LABLEX Advantage

Unique IMB LABLEX design provides significant maintenance advantages versus Screw-Plug exchanger closures: internal bolts aren't prone to deformation or overstressing, minimal tolerance for channel and lock ring threads for safer operation, gasket design delivers a leak tight seal even during critical transient conditions and differential thermal expansion.

One of the Biggest Ever Built

Shell ID 1981mm (78"). Weight 180 tons each. Design pressures of 179 and 200 bar on the shell and tube sides respectively. Assembled at the river port in Cremona, Italy and shipped to Saudi Arabia in a stacked condition.

Superior Aftersales

Dedicated experienced team available for training, supervision and technical assistance during start-up and commissioning, routine maintenance, debottlenecking and emergency shutdowns.

IMB Premium Jig

Hydraulically operated jig facilitates faster dismantling and reassembly. Opening the channels, removing and then reassembling or replacing the internals and reclosing the LABLEX becomes one seamless operation.
