Norwegian technology company Hydroniq Coolers has won a contract from Singapore-based shipping firm PSA Marine to supply seawater cooling systems.

Valid for a period of two years, the contract requires Hydroniq Coolers to deliver its Pleat seawater cooler to new PSA Marine ships.

The Pleat is a module-based titanium cooler, with a design pressure of six bars and design temperature of 0°C-95°C.

According to the agreement, Hydroniq Coolers will also be responsible for offering service and spare parts to PSA Marine’s existing fleet of ships at Singapore’s local storage facility.

Hydroniq Coolers sales and marketing vice-president Hans Robert Almestad said: “PSA Marine was actually the first company ever to test our Pleat seawater cooler at one of its tugs, operating in the busy Singapore Bay.

“The tug crew were used to having to clean its onboard plate heat exchangers two to three times per month but after installing the Pleat cooler they increased the maintenance interval to nine months or 39 weeks.

“Since then, we have been PSA Marine’s selected supplier and we are delighted to be able to extend our business relationship with a further two years.”

Using seawater, marine cooling systems lower temperature in the ship’s engines and other auxiliary systems to prevent engine overheating.

The seawater cooling system usually gets blocked due to particles present in the seawater. It requires cleaning to reduce system pressure. Otherwise, the blockages might cause the engine to overheat.

Hydroniq Coolers’ marine cooling technology provides services to cruise, passenger transport, offshore, fishery and fish farming ships.

Almestad further said: “Compared to a traditional heat exchanger, one Pleat cooling element is equal to approximately 15 plates.

“Whereas cleaning a traditional plate heat exchanger can take a significant amount of time to complete, cleaning of the Pleat can easily be done by one person within one hour. This is another reason why the Pleat is PSA Marine’s favoured solution.”

Owned by PSA International, PSA Marine has operations in Hong Kong, India, Bangladesh, China, Oman and Southeast Asia apart from its Singapore base.
