Durable neoprene end covers are available in a range of sizes. A wide range of over 40 model variants of body size and end cover type are available. See Pricebook Page 25.
Shell & Tube Oil Cooler Range. Bowman provides a comprehensive range of oil coolers with a range of different options for marine 7 industrial applications. The standardised design enables a range of different options from cooling capacity 4 to 900 kW heat disipation, oil port type (BSP-threaded, ISO-Flanged), supply end cover design (single, two or three pass), end cover type (Broass Tube-stack type (Cupro-nickel, Stainless steel or Titanium), end cover material (Bronze, Composite, Iron) and Seal type including for high temperature applications.
Available options include double Seal retaining flangeend covers to allow inspection and improve maintence down-time. In addition Titanium Tube Stacks are available for special order, provide a ‘fit and forget’ solution for any
application where very aggressive water conditions exist, such
as salt, or contaminated/mineral rich fresh water. Titanium
resists chemical attack and eliminates the risk of premature
failure of the tube stack.See Pricebook Page 26.

EXHAUST GAS RECOVERY
Exhaust Gas Recovery. An exhaust gas heat exchanger (EGHE) is an extremely effective way of recovering valuable waste heat energy from an engine powered generating set.
By recovering waste heat from the engine’s exhaust stream,the overall efficiency of a gen-set can be increased fromapproximately 30% (power only), to around 60% (with EGHEOnly) and 80% + when heat is recovered from the enginescooling system.
Bowman offer a comprehensive range of highly efficient units, suitable for applications up to1MW, for engines using Biogas, Diesel, Natural Gas and Hydrogen.Bowman EGHEs are designed for a wide range of commercial or industrial applications. Extensively proven in some of the most challengingi nstallations on earth, Bowman exhaust gas heat exchangers are high quality units that combine high levels of heat recovery, with long life durability.

It’s ultra-compact, so it can be installed virtually anywhere. And at its heart is a titanium tubestack enabling compatability with any type of pool water.
FREQUENTLY ASKED QUESTIONS
There are a number of factors to consider when projecting the life of a marine oil cooler. For example, has the correct product been selected for the cooling requirement? Has it been installed and commissioned correctly? Is the velocity (or flow rate) and pressure of the cooling medium within manufacturers recommendations? Has the unit been maintained and serviced in line with manufacturers requirements?
Assuming all the of the above questions (and possibly a few more) have been correctly addressed, there is no reason why a good quality marine oil cooler, from a well known, reputable company such as Bowman, shouldn’t last for more than 20 years. But to achieve this, it’s vital that the unit is correctly specified, installed, commissioned and maintained. For example, on marine oil coolers fitted with Cupro-nickel tube stacks, it is vitally important to ensure the copper-nickel alloy tubes are ‘conditioned’ correctly, to enable the thin layer of natural protective film to form on the tube surface, to provide long term corrosion protection.
Additionally, if the manufacturers recommended water flow rate is exceeded, high velocity seawater entering the oil cooler can quickly erode the tubes and tube plates, leading to premature failure, so following the guidelines is critical! And the well documented rise of plastic waste in our oceans, means that in addition to having adequate filtration of the incoming seawater, it’s also really important to inspect and clean an oil cooler regularly, to maintain its performance and extend the life of the unit! The good news is that if looked after correctly, a marine oil cooler can operate reliably for decades.
Bowman often hear of instances where their marine oil coolers have been working for more than 40 years!
