WATER OIL EXCHANGERS
- Heat exchanger with removable tubes bundle
Heat exchanger with removable tubes bundle
The above series represent natural addition and logically complete
series MS 84 and MS 134 by possessing major dimensions and
exchange surface that reaches 10 m2.
These series of heat exchangers have removable tube bundle which
makes them inspectable both from oil and water side. Thus, being
inspectable from both sides, these heat exchangers are perfectly
suitable for various applications with non filtrated liquids.
The material of which tube bundle itself is executed can be copper
– for performance with fresh water, copper-nickel – for marine water
and stainless steel – for applications with corrosive fluids and gas.
They consist of small diameter smooth tubes; this allows the best
compromise between high thermic yield and low pressure loss.
For a good exchanger practices some oil rates are indicated in the
tables. Going down to the lowest rate of flow indicated in the tables,
the low oil speed causes a great loss in yield, whereas a rate of flow
which is superior to the maximum indicated causes great pressure
loss and does not considerably increase the thermal yield.
The performance diagrams indicate the heat quantity each exchanger
can dissipate according to the difference between oil and water
mean temperatures.
Such diagrams assume the heat exchangers to be working with the
maximum oil flow rate indicated in the tables. With the minimum rate
the yield decreases by about 10%.
Required water volume s are the following:
85 l/h for each kW to dissipate with water temperature < or = 20°C
170 l/h for each kW to dissipate with water temperature > 20°C
The maximum working pressure allowed into the oil and water circuit
is 12 bar.
We would like to inform You that apart from standard series we are
able to manufacture whatever is special customized version of heat
exchanger possessing max. diameter of 500 mm and max. length of
4000 mm according to provided drawing.
