Print Version - APEX Group | Tubular heat exchangers

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.

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

Combustion Air Preheaters
Gas/Gas Reheaters
Gas Coolers
Heat Recovery Coils
DENOX Applications
DESOX Applications
Steam/Water Coils
Glycol Coils
for

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

Combustion Air

Fluegas from combustion of: gaseous fuels, liquid fuels, coal, wood, solid waste

Steam, water, glycol

Vapour, condensing or non-condensing

Industrial exhaust streams

Aluminium Finned Products
Steel tubes with aluminium fins 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.

Steel Finned Products
For heavy-duty environments, such as fluegases or industrial gases, the tubular coils are made of steel tubes with steel welded 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 moisture 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.
