BYIS manufactures heat transfer equipment, including steam boilers, steam generators, waste heat boilers and heat recovery steam generators.

BYIS is the world’s most respected manufacturer of Steam Generators used for thermal enhanced oil recovery.


BYIS has built over one thousand direct fired process heaters! The majority of these being of the cylindrical radiant – convection design. The design of the heater is dependent upon the specific application.

A sampling of the different designs is as follows:

  • Once Through steam generators for mining and oil recovery
  • Steam Super heaters
  • Acetic Acid Pyrolysis
  • Propane Cracking Furnaces
  • Titanium Tetrachloride Vaporizers and Super heaters
  • H2S Incinerators
  • Crude Oil Heaters
  • Coker Feed Heating

As a part of a continuous improvement effort we draw on the performances of the equipment in the field to check and verify the design practices.


These systems are designed to provide high temperature heat at low pressure to a large variety of down-steam equipment. Heaters provided have used every type of heat transfer fluid available. Size of the equipment has varied from 3.0 million btu/hr to 121.0 million btu/hr.

The heaters can be either horizontal or vertical and use a serpentine or helical coil depending upon the application. The heaters can be of radiant – convection type or convective type.


Thermal treatment of waste has become the best method of disposing of undesirable waste. BYIS offers a line of equipment to dispose of waste gases and liquids.


BYIS offers standard and custom design components for every piece of high temperature heat transfer systems. BYIS offers not only the components for a new system, but we are available for plant modernization, increase in capacity, and state of the art emissions control systems and efficiency improvements.

BYIS Ancillary Systems that can be supplied are:

  • Thermal fluid pumping and piping systems.
  • Combustion air preheaters
  • Waste heat recovery boilers
  • Expansion tanks and separators
  • Control Panels
  • Air Cooled exchangers
  • Prepiped and wired fuel system

Since the heaters come in all sizes; from skid-mounted units to field-erected models, BYIS tries to modularize the equipment to minimize the field erection time and costs.

BYIS is actively involved in steam generator operation worldwide. Major equipment has been supplied to Bakersfield, California, Venezuela, Colombia, Indonesia, Russia and Kuwait.
