Significant energy savings and optimal passenger comfort

Air-conditioning for passenger comfort is second to propulsion for using energy on a cruise ship and can account for 30-40% of fuel consumption which could be 50,000 tonnes of Bunker oil for a large cruise ship each year. The AB-QM, Pressure Independent Balancing and Control Valve, (PIBCV), can save 25-30% of HVAC energy costs compared to conventional distribution designs, equating to about US$1 million each year at today’s oil prices for a large modern cruise ship.

Less fuel, less emissions and more passenger comfort

Reduced commissioning and installiation time

Fewer AB-QM valves are required than in conventional designs, since balancing is done automatically inside the PIBCV. Chilled water flow can be modulated to match demand, achieving precise temperature regulation, optimized pump speeds and higher chiller efficiency.

Proven reliability

PIBCV technology has found application in the construction sector for the last 10 years with millions of valves in buildings around the world, proving the technology and reliability.

Return on investment – less than 1 year

The PIBCV is especially appropriate for cruise ships, ferries and luxury yachts, but all marine vessels with central heating or cooling and hydronic distribution will benefit. Energy savings will vary with size of vessel and number of heat exchangers, but the return on investment could be as little as three months for a large cruise liner.
