Compressed air is a common utility and source of power in many industrial plants and operations. It is well known that limiting the amount of moisture in compressed air is advantageous. Modern operations increasingly demand drier compressed air supply containing fewer contaminants. Some of the potentially damaging effects of moisture in compressed air systems include:

  • In air operated instruments, corrosion, leading to incorrect readings and false responses by plant operators.
  • In industrial processes utilizing pneumatic controls, clogging of orifices and malfunction of controls due to rust and scale can result in additional maintenance and repair, even process malfunction or shutdown.
  • In industrial spray-on coatings, moisture can affect their color, finish, and adherence.
  • In industrial production equipment, moving parts can experience rust and premature wear due to the washing away of lubrication by excessive moisture in compressed air.
For many industrial applications, removing moisture from compressed air can be accomplished on a continuous basis utilizing a properly configured mechanically refrigerated air dryer. SPX Flow Techonology's Pneumatic Products brand of refrigerated air dryers applies best in class refrigeration technology to deliver substantial energy savings to the process. The ESM product line features:

Steam Condensate Return Systems - Basic and Essential

Many industrial processes and plants utilize steam in their operations. The generation and use of steam is one of the oldest industrial processes and is so well understood that it may be considered more of a utility than part an industrial process. Whatever the case, if your process or installation uses steam, then steam is a necessary input for successful operation. Keeping your steam system performing at capacity frees up time and resources for the more complex aspects of your work.

If steam is not consumed directly by the process as a component input, it is steam's heat of vaporization that is utilized by the operation. Efficient use of steam as a heating medium results in the conversion of vapor to liquid (water). Returning the liquid condensate back to the boiler for conversion to vapor again is a necessary step in the efficient operation of a closed loop system.

Condensate return systems are certainly not high technology, but keep in mind that a steam system may be the lifeblood of not just one, but many operations throughout a plant. Avoiding downtime in the steam system, of which the condensate return pump is an integral part, ranks highly on the list of "Important Things for Plant Operations". Condensate return is critical. What are some strong attributes of a good and reliable condensate return pump?

  • Minimize or eliminate cavitation at high temperatures. Cavitation will impede pump performance and cause premature deterioration of pump and drive components.
  • Ability to handle a high load during cold starts through motor and pump design.
  • Design and configuration to handle high temperatures without deterioration of pump and motor.
  • Develop higher pressure at lower motor speeds for extended service life.
  • Avoidance of mechanical seals below water line.
  • Consider a single unit with dual pumps for handling high loads and extending service life.
Specifying and installing a solidly designed and built condensate return pump may require an investment of your time and consideration. The return on that investment will be reduced maintenance, repair, and downtime. Talk to a product specialist about your steam system. Combining your intimate operational knowledge and experience with their deep product knowledge and experience with many installations will yield a good solution.

Economical Suction Diffuser Provides Industrial Pump Protection

Liquid handling in industrial processes commonly involves the provision of a pump to move the fluid in the desired manner. Industrial pumps operate best and longest when they are provided with inlet conditions within a range for which the pump is designed. Two conditions prevalent among many pumps are low levels of particulate matter greater than a tolerable size and minimized turbulence at the pump inlet. Piping and specialties approaching the pump inlet should be arranged to provide these conditions to promote low vibration, energy savings, and a long service life.

An effective way to provide pump protection, save installation space, and reduce the probable demands for maintenance and service over the machine's expected operating life is to specify and install a suction diffuser at the pump inlet. There are numerous advantages to this approach.
  • The unit is mounted directly to the inlet side of the pump, saving space and additional connection points.
  • An integral strainer prevents unwanted materials from entering the pump inlet.
  • Straightening vanes on the outlet side of the suction diffuser reduce turbulence in the flow entering the pump.
  • Provision of a suction diffuser reduces the total parts count and connection points (joints) approaching the pump inlet. A single cast unit takes the place of a strainer, reducing elbow, and entrance pipe. Reduced installation time and cost are achieved using the integral design of the suction diffuser.

Industrial Steam Coils and Unit Heaters - Specify For Longevity

There are many applications for steam coils and unit heaters in the industrial  and processing fields. Lacking the sizzle of high technology, steam coils are simple, straight forward pieces of gear that are intended to transfer heat from steam to air. While simple in principle, their importance in process or application is notable. You are heating that air because it needs to be heated in order for something else to continue working properly. Steam coil thermal performance is predictable and well understood, making sizing of the coil tube and fin components a relatively simple task. A critical and practical element for steam coil selection is specifying attributes that will deliver ruggedness and longevity to reduce the probability of failure due to normal wear and tear associated with the process and installation environment.

Employing heavier gauge fins and tube walls can provide a longer service life. Cabinets or casings fabricated of corrosion resistant materials, such as stainless steel, may also lengthen the service life of the unit. Any motors, mountings, fan guards, or other hardware should also be evaluated for upgrading to enhance service life.

Of course, there is always cost involved. Examining the true cost of downtime to repair or replace a steam coil will likely show that some carefully considered options are well worth the comparatively small additional cost. Consult with a coil specialist. Discuss your application and see what construction enhancements will deliver longer on-line performance for your process.
