This oil cooler consists of a variable number of aluminium pressed plates forming oil ways and end tanks, the oil ways contain turbulators. These do not only break down boundary layer effects in the flow to obtain maximum heat dissipation without undue pressure drop but also, because they are brazed to both surfaces of the plates, hold them together under pressure. The oil ways are interspersed with aluminium strip louvered and formed into corrugations to provide airways.
The design is beautifully simple and efficient and most suitable for mass production, but it is restricted to a 2" thickness and a limited amount of lengths. The secret of the success of the Mocal cooler is our insistence on the highest standards of build quality allied to a rigorous inspection system. In particular the attention paid to the accuracy of the pressing tools to ensure the closest contact of the plates during the "Nocoloc" brazing process ensures our superiority over look-a-likes from the Far East.
Maximum working pressure on the standard range of coolers is 10 bar (150psi)although each cooler is tested to 11.5 bar (170psi) this is adequate for all but the most arduous motoring applications, however some customers prefer a higher pressure rating, for instance where the pressure by pass valve does not provide enough protection as in high rpm in cold start up conditions or on dry sump installations.
Please Note: Fluid connections are ORB 1/2" BSP. These connections are available in either -8AN or -10AN and are sold separately.
