Tubular Heat Exchangers

APEX Group offers a range of tubular exchangers of proprietary or conventional design used as heat recovery units for a diversity of fired and non-fired installations.

The tubular exchangers may be supplied as stand-alone heat recovery units or in combination with plate-type and glass enamelled or teflon coated exchangers to form complex, integrated heat recovery units.

Applications & Industries
APEX Group has proven the suitability of its products for the following fields of applications:

  • Liquid / Air
  • Liquid / Gas Reheaters
  • Steam / Air
  • Steam / Gas
  • Process Streams / Air
  • Process Streams / Gas
  • Heat Recovery Coils
  • DENOX Applications
  • DESOX Applications
  • Steam / Water Coils
  • Glycol Coils
  • Oil / Air

Fluids Handled
These products are suitable for handling a large diversity of fluids, such as:

  • Air
  • Fluegas from combustion of: gaseous fuels, liquid fuels, coal, wood, solid waste
  • Steam, water, glycol, oil
  • Vapour, condensing or non-condensing
  • Process Streams
  • Industrial exhaust streams

Aluminium Finned Products
Steel tubes with aluminium fins, produced under high standards of quality by APEX Group using highly qualified personnel, are suitable for handling only clean gases, most commonly air. APEX Group offers a diversity of designs specially developed for applications such as air tempering and air preheating for combustion processes and for the process industry. The heating medium is steam, water/condensate, or water/glycol mixtures for freezing environments. APEX Group also sells Finned tubes directly.

Steel Finned Products
For heavy-duty environments, such as fluegases or industrial gases, the tubular coils are made of steel tubes with welded steel fins. Such units of a conventional design are used as convection section modules and gas-cooling modules for fired heaters, environmental projects, process industry, etc.

Bare Tube Products
For applications with excessive fouling tendency or with excessively high temperatures the coils are made of bare tubes. On-line water washing devices may be provided for moist and/or dust-laden gases operating at low temperatures. Bare tube products may be designed in combination with finned products to cover a wider range of process conditions within the same apparatus.
