We are specialized in engineering, manufacturing and marketing marine and industrial heat exchanges, fans and cooling systems.
VDL Klima b.v. has been based in Eindhoven, The Netherlands since 1908. We are specialized in engineering, manufacturing and marketing marine and industrial heat exchanges, fans and cooling systems.

Our ability to design and manufacture innovative and high quality products enables us to maintain a leading position in a very competitive market. In short, innovation and hign quality are the key to our success.
The Working principle of the boxcooler
The boxcooler works on the principle of the thermal siphon effect ( where differences in the specific mass of water due to a temperature gradient cause circulation). The boxcooler is positioned inside a sea-chest with inlet and outlet slots.

Engine cooling water is pumped through the tubes of the cooler and cooled by the forces circulation of raw water through the sea-chest when the vessel is sailing. When the vessel is in idle position, water circulation in the sea-chest is caused by thermal siphon effect.
Application :

There are no limitations on the way the boxcooler can be applied other than the physical space available inside the vessel in combination with the amount of heat that needs to be dissipated.

Type of Vessel Heat Sources
    Tug boats     Main engines
    Supply vessels     Auxiliary engines
    Ice breakers     Bow thrusters
    Dredgers     Air-conditioning systems
    Fishing vessels     Hydraulic systems
    Cargo ships  

The advantages of Klima boxcoolers compared to other designs of cooling system

The entire secondary raw water cooling system is eliminated. Cooling efficiency is hardly affected by polluted water or water containing broken ice.

The boxcooler is much less susceptible to corrosion and fouling than other designs of cooling system. Less technical complication reduces the risk of breakdowns.

Klima boxcoolers reduce costs

Lower installation costs.
No need to overhaul raw water pumps and piping every 5 years.
No spare parts
Reduced auxiliary power requirement ( saves fuel and energy)
Low maintenance costs
Less items requiring nautical certification testing
