PARAT Halvorsen with new exclusive tubes for our Marine boilers

This will give our customers the option to reduce the height of the boilers by up to 30% or increase capacity of the boiler of up to 30%. Also allowing longer operational cycles, less maintenance, significantly less cleaning and less downtime.

  • Significant weight reduction by increased heat transfer – 30% reduced length
  • Optimized pipe turbulence, decreases scaling and the need for cleaning
  • Increased resistance to thermal expansion stresses

PARAT Halvorsen with new exclusive tubes for our Marine boilersThe NEW Tube technology increases the heat transfer coefficient by a factor of two to three compared with plain tubes. 


PARAT have an exclusive agreement with the Tube producer for using these tubes in Norway on our Exhaust Gas and Smoke Tube boilers. This will give our customers the option to reduce the height of the boilers by up to 30% or increase capacity of up to 30%. This can be an excellent solution if boiler weight and size is important on your vessel.

This will be a great option to consider for the PARAT MCS Combined Smoke Tube/Exhaust Gas BoilerMVS Smoke Tube Boiler and MES Exhaust Gas Smoke Tube boiler.



TUBE BENEFITS
The NEW Tube technology increases the heat transfer coefficient by a factor of two to three compared with plain tubes.

The New tubes has a much higher efficiency compared to regular IP tubes.



HIGHER EFFICIENCY
The structure of the tubes has an effect on the fluid dynamics. The dimples on the tube affect the boundary layers in such a way that tangential and radial mixing motions occur. As a result, a turbulent flow arises early on Inside and outside the tube, causing the heat transfer to increase.

Due to their structured surfaces,the NEW Tubes have a relatively low resistance to thermal-related expansion compared with plain tubes and possess special strength properties.

LESS FOULING
Particles that are present within the media settle at a much lower rate on the tube walls because a significant proportion is carried away by the turbulent flow, thus allowing longer operational cycles, less maintenance, significantly less cleaning and less downtime.
