Customization
Sperre has specialized its production of heat exchangers to enable customized solutions based on standard heat exchanger models. We have advanced computer programs for calculating the thermal performance of our heat exchangers effectively and accurately.
Dimensions
Sperre offers more than 200 standard models of shell and tube heat exchangers with cooling surfaces from 0.2 to 350 m2. The outer physical measurements are limited to a diameter of 1 m and a length of 4 m..
Pressure classes
Sperre supplies shell and tube heat exchangers with design pressures ranging from 10 to 100 bar depending on size. All of our heat exchangers are hydrostatically pressure-tested, and supplied with a pressure test certificate.
Documentation
ocumentation compliant with the customer’s specifications or the classification company's requirements is routinely included with each delivery, and all our standard shell and tube heat exchangers have type approval from all the marine classification companies. ( DNV, ABS, GL, MRS, RIA, BV, etc.)
Materials
Sperre has a wealth of experience in working with special material types, and our highly qualified technical personnel can advise on appropriate materials for even the most demanding operating conditions. We supply shell and tube heat exchangers in the following materials:
Tubes
Al/brass, CuNi 90/10, CuNi 70/30, carbon steel, stainless steel and titanium
Tube plates
Munz metal, carbon steel, stainless steel and titanium
Baffles
Munz metal, carbon steel, stainless steel and titanium
Shell
Carbon steel, low-temperature steel and stainless steel
Water boxes
Cast iron, bronze, carbon steel, stainless steel and titanium
Applications
Sperre produces shell and tube heat exchangers for the following purposes:
Coolers
Oil coolers for lube oils, hydraulic oils and thermal oils. Freshwater coolers for main engines and auxiliary engines.
Coolers for exhaust gases from diesel engines in Ex areas.
Preheaters
Freshwater preheaters for process facilities and central heating systems. Seawater or fresh-water preheaters for tank-cleaning and for heating swimming pools, for example on cruise vessels. Oil preheaters for thermal oils, diesel oils and heavy fuel oils. Preheaters for LPG. Cargo heaters for chemicals in transport.
Condensers and evaporators
Steam condensers for dumping steam.
Condensers and evaporators for refrigeration facilities, such as ammonia and freon condensers.
Spare parts
We deliver all spare parts, such as water boxes, gaskets, packing glands, O-rings, plugs and zinc anodes, anywhere in the world within 48 hours. Rapid delivery of complete heat exchangers, shells and tube bundles is also a high-priority objective for Sperre.
Quality
Sperre has won a reputation for supplying high-quality heat exchangers that will have a long lifetime under demanding operating conditions. For example, all Sperre’s heat exchangers are manufactured to allow thermal expansion to take place without causing leaks or other damage. The walls of the water box and shell are thick enough to withstand a great deal of corrosion before any leakage occurs. In marine applications, this has the added benefit that it takes longer before the heat exchanger needs cleaning because of bio-fouling. To lengthen the lifetime of the heat exchanger, our calculations focus on achieving conservative operating conditions. We use only smooth tubes in our heat exchangers, which makes it possible to replace individual tubes in the tube bundle. All our heat exchangers are especially easy to dismantle, assemble and maintain
