Compressed air systems are, for many industrial installations, the lifeblood energy source. Keeping the system free of unwanted particulates, oil, moisture, and other harmful contaminates is a key step in maintaining full operational capacity and conserving energy. Instruments, tools, and equipment that utilize the compressed air will perform better and longer with a cleaner air supply.

Coalescing filters are designed to remove liquid aerosols from compressed air or gas streams. Locating the filters upstream of air dryers will provide a processing step that intercepts liquid aerosols and brings them together (coalesce) into larger droplets that migrate to the bottom of the filter housing and are removed by draining. The purpose of locating the coalescing filter upstream of the air dryer is to remove liquids the dryer is unable to remove.

Some desirable criteria for coalescing filters include low penetration of oil and low saturated pressure drop. Increased pressure drop will require proportional increases in energy to maintain rated system air flow.

Along with moisture, inlet air can contain a range of particulates. Filter media that is designed and constructed to trap and retain larger amounts of particulate matter can be beneficial because the time between filter media changes is extended.

Effective compressed air system design requires the inclusion of properly configured and sized filtration components. You can learn more about coalescing filters with a review of the document included below. It includes some quantitative means of rating filter performance and efficiency.

There are many applications for clean steam throughout the industrial processing, food and beverage, pharmaceutical, institutional, electronics, and healthcare fields. Clean steam is produced by a secondary generator using a controlled feedwater source free of contaminates that may be detrimental to the process or activity where the final steam product is used. An example, applicable in many areas, is humidification of supply air in a plant, commercial, or institutional building. In some humidification designs, steam is injected or dispersed directly into the air flowing through a duct delivering supply air to occupied spaces. The steam, absorbed by the supply air and increasing its moisture content, becomes part of the atmosphere in the human occupied space. Carryover of commercial boiler feedwater chemicals or other potential contaminates will adversely impact the air quality. A secondary clean steam generator, heated with steam from the central plant boiler and utilizing properly treated or purified feedwater, delivers steam to the humidification system free of unwanted substances.

The application of a familiar commercial boiler as a secondary generator is generally not a solution to the production of clean steam. In most instances of clean steam generation, the feedwater is treated and purified to a condition that makes it aggressive to the range of steel types used in the fabrication of boilers intended for common industrial use. Clean steam generators need fabrication from stainless steel or other metals that can withstand the corrosive effects of purified water.

Spirax Sarco, known globally for their expertise in steam specialties, provides a packaged answer to the need for clean steam. The company's CSM-C 600 Compact Clean Steam Generator includes everything needed to produce clean steam, once utilities are connected. This complete solution simplifies the task of upgrading an existing process to utilize clean steam or provide new capacity.

A technical data sheet for the unit is provided below. For more information or application assistance, reach out to a product specialist and share your process steam challenges. The best solutions come from combining your process knowledge with their product application expertise.

Industrial process control applications, by their very scale and nature in financial, operational, and safety terms, call for rugged and well performing devices and equipment. In the area of temperature and pressure related control, switches are often employed to achieve or respond to an enormous range of possible conditions.

Temperature and pressure switch reliability is especially critical in applications located within hazardous zones or locations. Custom Control Sensors (CCS) manufactures pressure and temperature switches for the most demanding applications in hazardous environments.

Products are designed to provide high cycle life through the use of a Belleville spring to reduce mechanical wear on the switch element. The switches have no moving parts, other than the actuating mechanism which has a limited movement of 0.01 inch.


CCS products for hazardous locations are routine deployed on

  • Oil Platforms
  • Pump Control
  • Refineries
  • Control and Annunciator Panels
  • Relay Alarm Systems
  • Pipelines
  • Gas/Steam Turbines
  • Oil Filtration

Included below is a short form catalog illustrating the CCS line of pressure and temperature switches for hazardous and non-hazardous locations. In addition to the suitability of the industrial switches for use in hazardous areas, CCS temperature and pressure switches exhibit these main features:

  • High Cycle Life
  • Wide Range of Set Points
  • Protection Against Environment
  • High Over-Pressure Capability
  • No calibration needed
  • Maintenance free
  • High vibration resistance
