Industrie Meccaniche di Bagnolo (IMB) is renowned for its expertise meeting challenging heat exchanger requirements, including high pressures and temperatures, complex fabrication, critical welding and specialist metallurgy, for multiple applications across the oil and gas refining and petrochemical processing sectors.

Principal products include:


LUMMUS ADVANCED BREECH-LOCK EXCHANGER® With >700 units in operation, IMB is responsible for >50% of the world’s capacity for LABLEX®.

LABLEX® is utilized in high-temperature/high-pressure applications including hydrocracking, hydro-treating, gas compression, ammonia/urea synthesis and methanol production.


Compared with conventional solutions, LABLEX® provides increased plant reliability and lowest total life-cycle cost through simplified and efficient operation and reduced servicing requirements. To learn more visit our LABLEX® page

SPINTUBE™ Replacement Bundles

SPINTUBE replacement tube profile The unique profile of SPINTUBE provides up to 40% better heat transfer performance than the round tube of a conventional shell and tube heat exchanger.

SPINTUBE replacement bundles can be applied to any TEMA shell and tube unit and are ideal for plant upgrades and debottlenecking.

HELIXCHANGERHELIXCHANGER® is an alternative to conventional shell and tube heat exchangers and delivers up to 30% reduced physical size and/or fewer shells, which means significant savings in capital costs with reduced piping, structure and plot plan. Replacing a conventional tube bundle with HELIXCHANGER® for a plant revamp will deliver increases in processing capacity up to 40%. Existing shells and piping can be retained delivering further cost savings.

Typical services in the gas processing, refining, petrochemical and chemical industries include:

  • Crude preheat exchangers
  • Feed preheaters
  • Oil coolers
  • Process gas coolers
  • Compressor aftercoolers
  • Reactor feed-effluent exchangers
  • Overhead condensers
  • Column reboilers

Hairpin Heat Exchangers

Hairpin Heat Exchangers Hairpin heat exchangers use true counter-current flow to maximize temperature differences between shell- side and tube-side fluids.

They are especially suited to applications where a traditional shell and tube arrangement is uneconomical, where space is at a premium and are the most efficient design when a process requires a temperature cross i.e. the hot fluid outlet temperature is below the cold fluid outlet temperature.

Multiple units can be assembled in parallel or series and units can be mounted horizontally or vertically for even greater versatility.

IMB builds both double pipe and multi-tube hairpin exchangers for oil and gas processing, natural gas storage, LNG and power generation.

Heat Exchangers for Offshore

Maximizing performance while minimizing space is the most critical aspect of every offshore installation. Through our long association and proven track record in the industry, IMB recognizes this and our technical expertise is highly prized by our customers. From large hairpin heat exchanger installations to sub-sea coolers, IMB provides the most comprehensive selection of custom designed tubular heat exchanger products and solutions. Furthermore, our technical consultancy, training and aftermarket service is second to none.

Heat Exchangers for Offshore

We supplied critical equipment for the first subsea gas compression plant in the world.

The Asgard subsea compression project places compressors on the seabed 300m below the surface and uses direct seawater cooling to send liquefied gas to the surface. Compared to a typical platform installation it improves the production yield by 280 million barrels of oil equivalent and significantly reduces CO2 emissions.
