TOLL Shipping has 2 new builds each with 2 slow speed HYUNDAI MAN B&W 9S40ME-B9.5-TII main engines

Each main engine has an ABB A170L37 turbocharger with a fabricated steel Air Filter Silencer with a diameter of 1280mm x inlet area of 520mm.

The standard air mat is used over the top of a metal mesh and a fine nylon screen. The company wanted to reduce waste as well as maintain the efficiency of the engines, which is important on a time critical service.

A framework of steel flanges and spacer bars is used to hold and support a PMAX Filter in place on the AFS. No modifications to the OEM, AFS was necessary to fit the PMAX Filters.

Manufactured in 2 pieces, the PMAX Filter fits very easily on to the carriage assembly.

Running with the standard OEM filter plus wrap the DP was over 200mm water gauge, (WG). The PMAX filter reduced to differential pressure to 140mm water gauge. The OEM manometer seen here at normal full away load is reading 140mm WG whilst the PMAX manometer is reading 80mm WG. The reason for the difference in the 2 manometers is due to where the sensing points on the AFS’s are. Water gauge is a very sensitive and light medium to measure air differential pressure.

The OEM filter is a simple wrap, measuring 4M in length while the length of the PMAX filter with it’s pleated form is 12.6M. The extra material is not only important for air flow but also allows a greater dirt load to be carried within the element, without reducing air flow. The PMAX filters are washed once a month and have now been in constant use for over 2 years with absolutely no issues at all.

Dole is the largest reefer ship company in the world, operating 19 ships. We met the senior ship managers at the 2022 SMM who expressed an interest in trialing PMAX Filters on one of their vessel.

Some say why have an air filter on a ship at sea. Unfiltered engines have poor efficiency, high fuel consumption, less power and high exhaust temperatures.

A PMAX Filter fitted to the fwd main engine. An innovative securing arrangement was supplied to fit the filter with minimal work required by the excellent engineering crew.

The pleated filter is in 2 pieces, washable and expected to last for 5 years or 30,000 engine hours.

MS Stena Europe has Wartsila 12V32 Vasa engines with older ABB VTR 250 turbocharger on both the main engines and AE’s. PMAX Filters were first fitted to all the engines in 2008.

PMAX filters were first fitted on all the VTR 250 turbochargers in 2008 with a view to increase engine efficiency, reduce fuel consumption, reduce maintenance costs and reduce exhaust temperatures.

The following are emails sent by the Chief Engineers

8/6/2008

Tim,

We received the filters in good order and have had them fitted to the main engines. They look great and are very simple to install.

Under our normal operating parameters we have found the exhaust temperatures have dropped around 20-30 degrees and T/C revs increased by 1000 and boost pressure increased by 0.15 bar. Needless to say we are well impressed with improvement and obvious fuel savings we should make.

No.3 ME has just had two reconditioned T/C’s fitted and clean air coolers so should be a good indicator for the cleaning cycle of the air coolers.

I have copied this e-mail to our Technical Manager and Fleet superintendent for their assessment.

At a guess would say the filters last for around the 25000-30000hours, but could be more. As they get swapped around its hard to keep track.

Cleaner we use is Enviromate 2000 from drew marine which is not too aggressive which seems to work well for us giving us little bother.

The main engines themselves are getting close to 175,000 hours and generators 250,000 hours and still plodding away. Great engines!

OEM filters are a coarse copper gauze which cannot filter out dust, exhaust fumes, oil and other pollutants. PMAX Filters are washable and will increase engine efficiency, reduce fuel consumption and remove the cost and need to remove charge air coolers to be cleaned in acid baths.

PMAX Filters together with our UK distributor MarShip UK exhibited at the SMM Exhibition in Hamburg Germany. SMM occurs every second year & is the world’s foremost, best & most respected marine trade fair.

Tim Clarke, PMAX Filters on the left & Peter Weide, MarShip UK on the right had a productive week at the show, speaking to over 100 potential customers.

Welcome visitors were our Scandinavian distributors, Ditech AS from Norway, Johannes Solsvik & Oyvind Siversten.

Also visiting from Singapore on the left was Thaw Thaw Han from the THOME GROUP, Singapore & Intership Navigation Co., Cyprus, purchasers Teresa Shakidou & Alexis Ionnou.

The Trade Show was such a success a forward booking for SMM 2024 has been arranged.

LOWER RUNNING COSTS INCREASED ENGINE EFFICIENCY

PMAX FILTERS present over 700% more surface area to inlet than conventional coarse gauze filters. The basic design of conventional filters has not improved in more than 60 years of turbocharger development.

Unlike conventional filters, PMAX FILTERS arrest exhaust fumes, dust, oil and salt particles, yet still supply sufficient air to run slow and medium speed diesel engines at maximum efficiency.

Manufactured and available internationally, PMAX water washable filters are designed to provide many thousands of hour’s service.

PMAX FILTERS are easily fitted to: Slow, Medium and High-Speed Diesel Engines.

PMAX FILTERS achieve cost savings and reduced impact on the environment through:

• Reduced fuel consumption and cleaner exhausts

PMAX FILTERS reduce the internal build-up of contaminants that restrict airflow and cause a subsequent rise in fuel consumption.

• Reduced maintenance

Less build-up means less frequent need to remove charge air coolers for cleaning, minimising downtime.

• Greater engine efficiency and reliability

Cleaner, less restricted air paths provide consistently lower exhaust temperatures, so engines deliver maximum power with less risk of burnt exhaust valves.

• Less component wear

With PMAX FILTERS, there are fewer abrasive particles in the charge air to damage pistons, piston rings, cylinder liners, valves and valve seats.

• Environmentally friendly

PMAX FILTERS are water washable for many years trouble-free service and keep engines running efficiently with cleaner exhausts.

• Environmentally responsible

PMAX FILTERS provide a 100% air seal to effectively catch pollutants, unlike copper gauze or cheap throw-away wraps.

PMAX FILTERS suit all engines including:

Akasaka, Bergen, Caterpillar, Cummins, Daihatsu, Deutz, EMD, General Electric, Gotaverken, Hanshin, MaK, MAN, MAN B&W Alpha, Mirrlees Blackstone, Mitsubishi, Mitsui, MTU, Nigata, NohabPolar, Pielstick, Ruston, Stork Werkspoor, Sulzer, Wartsila, Wichmmann, Yanmar

What our customers say:

From the P&O letter:

“I have no hesitation in recommending PMAX FILTERS to other shipping companies who are concerned about their operating efficiency and bottom line.”

From the Toll letter:

“The Chief Engineers from both vessels agree that the fitment of the filters is a quantum leap ahead in respect of improvement of engine performance, operating efficiency, reduced maintenance and cost savings.”

From the Oceangas letter:

“Apart from reducing the amount of engine maintenance, the filters are designed so that they are aesthetically pleasing, not bulky and easy to clean. In our eyes, the filters are an asset and have already paid for themselves. …We strongly recommend any ship owner to explore the possibility of installing PMAX FILTERS.”
