Tube bundle heat exchanger

General information about shell and tube heat exchangers

Tubular heat exchangers transfer thermal energy from one liquid or gaseous medium to another. With a double-tube version, these two media can be safely separated from each other. The design of these heat exchangers makes them very robust, so they are also suitable for demanding operating conditions.

Application fields

  • Oil coolers for engines
  • Compressors
  • Lubricating oil systems.
  • Oil coolers for plain bearings (also for self-pumping bearings)
  • Gas preheating

 

Advantages of shell-and-tube heat exchangers

  • Modular system for optimal thermal matching
  • Safety heat exchanger available
  • Compact design
  • High thermal efficiency
  • Insensitive to back shocks
  • Low pressure drop

 

Technical features

  Oil volume:  up to 2500 l/min
  Achievable power:  up to 2000 kW
  Pressure stage jacket side:  PN 16 (higher pressure rating on request)
  Pipe side pressure rating:  PN 10 (higher pressure rating on request)

 

Plate heat exchanger

General information about plate heat exchangers

Plate heat exchangers transfer thermal energy from one liquid medium to a second liquid medium. If required, these heat exchangers can also be supplemented with safety plates, which ensures safe separation of the two media. Plate heat exchangers are available in several designs - allowing them to be adapted to different thermal conditions. Freeflow plate heat exchangers and spiral heat exchangers can also thermally process contaminated media.

Application fields

  • Heating and refrigeration
  • Heat recovery
  • Cooling circuits
  • Process media (also loaded with solids)
  • Waste water and sludges
  • Condensation or evaporation processes

 

Advantages of plate heat exchangers

  • Variety of technical designs possible
  • Large selection of plate dimensions - optimal adaptation of operating data
  • Safety heat exchangers available
  • Partially and fully welded design available
  • Freeflow-WT for media with solid content - Free media channel
  • Spiral-WT for heavily loaded media (e. g. e.g. sludge)
  • High pressure stability

 

Technical features

Nominal connection size:DN 25 (1") - DN 700
Plate materials:AISI304, AISI316, AISI316L, AISI316TI, SMO254, titanium, resp. others on request
Sealing materials:NBR, EPDM, FKM, PTFE, copper solder, nickel solder

 

air heat exchanger

General information about air heat exchangers

These heat exchangers are used to cool liquid media by the ambient air. The air is pulled or pushed over a finned tube bundle by means of a fan. In combination with an oil pump on the motor shaft, a drive can be used to power the fan and pump.

Application fields

  • Oil cooler
  • Water cooler

 

Advantages of air heat exchangers

  • Compact design
  • Easy installation

 

Technical features

  Achievable power:  4.4 kW to 140 kW (at 40 °C temperature difference)
  Possible oil volume:  Up to 600 l/min

 

Electric heaters

General information about electric heaters

Electric heaters are used to heat liquid media. They can be installed as continuous flow heaters in pipelines, heat an entire container content or only the withdrawn quantity. If one combines the electric heater with a pump and fittings, complete preheating units can also be realized.

Application fields

  • Oil preheating
  • Fuel preheating
  • Tank heating
  • District heating - energy coupling (P2H)

 

Advantages of electric heaters

  • Gentle heating due to low surface load of the heating rods
  • Heating rods for oil and emulsion can be removed from the tank without draining.
  • Deliverable incl. terminal box or with complete control

 

Technical features

  Achievable power:  up to 1000 kW
  Surface load oil or emulsion:  0.9 - 1.8 W/cm²
  Surface load water:  6 - 8 W/cm²

 

 

Submerged water heaters

General information about underwater coolers

With underwater coolers, cooling circuits can be cooled directly by river water. In this case, the cooler is washed by the river water and thus extracts the heat from the cooler water in the pipes. The use of submersible coolers eliminates the need to extract the river water, filter it, pipe it to the heat exchanger, and return it to the river.

Application fields

Cooling circuit in power plants and industrial plants

 

Advantages of underwater coolers

  • Direct heat transfer from cooling water to river water
  • Space-saving design
  • Individual dimensions
  • Corrosion-resistant materials

 

Technical features

  • Tube bundle made of CuZn20Al2 with multiple coating
  • Water chamber with connections made of stainless steel
