General
Pressure and Temperature
Up to the size of BEM 304 this series is identical in performance with the series
T 80. This inside construction conforms with series T 80. As from BEM 502 this
series covers a performance range up to approx. 2500 kW.
The standard version will be supplied in five different materials. However
depending on the requirement of the medium, all kinds of material can be used
for production.
The material for housing and bundles can thus be exactly adjusted to the demand. If stainless steel is requested on the water side, please ask for our special
information!
The heat exchangers will be manufactured with inspections according to R.I.N.A., LLOYD`S Register, ABS and NORSKE VERITAS for the ship building.
The factory`s production standard is A.S.M.E. and T.E.M.A.
The series is available with 25 and 50 bar within the normal delivery time. If
required, an operating pressure of up to 420 bar can be produced.
In case of high temperatures up to 800 °C, the series BEW should be used.
The series BEW has ductile bundle. This bundle design can take up length extensions and prevent tensions in the housing. The bundle of the series BEW has
a double sealing. A mixture of the agents between housing and bundle will thus
be eliminated.
The series BP has a bundle with a firm and loose bundle head. It is therefore
possible to compensate the lengths at temperatures, however the bundle is not
ductile, contrary to the series BEW. Please ask for a detailed description of series
BEW + BP. Beyond it all types and designs are available according T.E.M.A. (Tubular Exchanger Manufactors Ass.) Please ask for single drawings and offers.

When operating the heat exchangers with a cooling agent " water ", stainless steel should not be used. There is danger of localized corrosion, if a certain water quality will not be kept. The coolers with tubes of CuZn20Al2 are being equipped with zinc protection anode.
Information of Installation By using the 2-and 4-way system on the water side, the cooler is independent of the inlet and outlet of both agents. This applies to the
housing as well as to the bundles.
Construction of the Cooler The construction of this series conforms with the system of series T 80 The
bundle tubes have aclear diameter of 10,5 mm. The wall thickness is 1,25 mm
without fin. The cooling water will be diverted in the cover.
A later modification to a 2- or 1-way design on the water side is possible without dismantling of the heat exchanger. On the oil side the heat exchanger will
be designed by arrangement and size of the diversion baffles to the oil quantity.
The adjustment is necessary when using very stringy oil or large oil flows.
The inlet and outlet can thus be chosen freely according to the requirements and the constructive space conditions. The counterflow system will be kept in any case.
The oil connection will be equipped with any required thread,
DIN or SAE flange. The standard design of the cooler have BSP tube threads.
The housing connections can be supplied in reverse order by 90 °C in every chosen direction. (not suppliable ex stock)
As standard design this series is a 4-way system. Depending on the design,
however, also the 2-way design will be applied.
With our system of cooling water diversion in the covers, a later modification from 4- to 2- or 1-way diversion on the water side is possible. The oil side
diversions cannot be changed afterwards.
Type Codes The types mark the individual tables with the performance data.
