Using Blokland boxcoolers in the design of efficient cooling system, has been done during many years for different types and sizes of ime vessels and installations. Installed in the primary cooling circuit, boxcoolers obviate the need for raw water pumps, filters and piping systems and prevent the corrosion issues related to them. Over the years different types of workboats, cargo vessels, fishing boats, ferries and dredgers have been using these coolers for main engines, generators and auxiliary systems. Nowadays boxcoolers are not only used in modern fuel-saving and green fuel propulsion solutions, but are also part of the fuel saving measures.

The bottom-type cooler is an ideal cooling system for pleasure and commercial shipping. The steel box of the bottom-type cooler is placed inside against the bottom of the ship. As a result, the bottom of the ship remains completely smooth. So there are no protruding parts to damage or weed trays to clog. You do not need an extra outboard water pump in this case. Installation is simple and the tube stack can be disassembled. Bottom-type coolers are very suitable for places with a low installation height.

Blokland is leading in the production and supply of Shell & Tube heat exchangers/oil coolers type 100, 140, 165, 200, 275 and 400. These coolers are suitable for water, water-glycol mixture and various oils. The tube stacks are removable for service and maintenance. Blokland has a wide range of competitively-priced heat exchangers. We have many heat exchangers in stock, which means short lead times.

The plate heat exchangers consists of a pack of heat transfer plates, with port holes, compressed by the frames and tightening bolts. The plates are made of pressed titanium or stainless steel sheet metal with a corrugated pattern. The corrugated plate channel are designed to achieve maximum heat transfer. Each plate is provided with an elastomeric gasket which seals between channel and directs the fluids into alternate channel.
