Clean Hydrogen – cooling the marine industry’s ‘zero emissions silver bullet’

Hydrogen fuel cells have enormous potential as a ‘zero emissions’ fuel for the marine industry, but correct system cooling is vitally important. Thankfully, Bowman has the solution!

Why selecting the right heat exchanger is vital for your pool

‘’Why are Bowman heat exchangers so efficient?’’ and ‘’How can such a small heat exchanger possibly heat a pool this size?’’ These two questions are often asked and the answer is really simple.

Electric Ferry with Bowman Heat Exchangers

Choosing the right heat exchanger for electric or hybrid marine cooling

In just a few years, electric and hybrid propulsion has gone from a niche market enterprise to a serious mainstream solution for marine propulsion systems.

Reducing hot tub heating costs – significantly!

Rising energy costs are making many owners to reconsider using their hot tubs, but this solution heats them fast and can reduce energy costs by over 60%!

Exhaust Gas Heat Exchangers – The Great Pressure Drop Myth!

Adding a heat exchanger to a gen-set's engine exhaust stream not only recovers valuable heat energy, it can also help to reduce pressure drop!

What is an Intercooler and how does it work?

Intercoolers play a vital role in ensuring turbocharged engines operate at their optimum efficiency. Find out how they work and the types of intercoolers available.

Why doesn’t my pool heat up faster?

If your pool isn’t heating up to the required temperature, there are a few possible causes. Using this check list could help you locate the problem:

Zinc anodes

Fed up of replacing zinc anodes on your cooler? Find out why Bowman heat exchangers don’t need them....

Clean hydraulic oil coolers quickly and safely

Keeping heat exchanger and oil cooler cooling tubes clean and clear from debris is a major issue. Bowman's Double Seal Retaining Flange offers an easy solution.

Recovering waste heat from a biogas fuelled gen-set

Biogas is becoming increasingly popular for fuelling generating sets. But why only generate power when you can recover heat too?

How do I heat my pool faster?

It's a question asked so many times by pool owners. Yet the answer could be far simpler than you might expect!

Terminal velocity..…Don’t let it kill your heat exchanger!

Ensuring the correct velocity of cooling medium through the heat exchanger is vital to the long-term health of the unit. Get it wrong and results could be terminal.

How to heat a hot tub faster…

Significantly faster heat-up times and reduced energy costs. Why using an external heat source, linked to a Bowman heat exchanger, is revolutionising hot tub heating.

Recovering waste heat from an engine powered gen-set

The benefits of recovering waste heat from an engine powered gen-set.

What is an exhaust gas heat exchanger?

An engine exhaust produces waste heat - and lots of it! Find out how an exhaust gas heat exchanger converts this heat into a valuable 'free' energy source.

Is stagnant water killing your heat exchanger?

Water left inside for prolonged periods can ruin a heat exchanger. Here we show how to eliminate the danger of stagnant water contamination.

What is counterflow? Why is it more efficient?

With a counterflow arrangement, the cooling medium flows in the opposite direction to the liquid being cooled. Find out why this is so much more efficient.

Single, double or triple pass cooling – what’s the difference?

Understand the importance of flow rates and how cooler selection can make the most of the coolant at your disposal....
