  1. The Different Types of Steam in Industrial Steam Generation

    Leave a Comment

    Industrial facilities rely on different types of steam to manage tasks ranging from consistent heating and processing to managing sanitation. There are many steam types available, and choosing the right one for a given application is essential. At Electro-Steam, we provide steam generation systems suitable for a wide variety of industrial steam needs. This guide will break down the different types of steam frequently used in industrial contexts to help you find the type you need for your facility.

    Types of Steam

    Learn more about the different benefits and applications of these common types of industrial steam.

    Dry Steam

    Dry steam is a type of steam with no lingering liquid in the fluid. All of the liquid has been changed to a vapor. Superheated steam, for example, has been heated to the point where no liquid remains. Other steams can act as dry steam, provided there’s a built-in method to capture the liquid before it reaches an application surface.

    Saturated Steam

    Saturated steam is a specialized type of dry steam. While there may be some liquid remaining in the vapor, it can be easily trapped and contained. In saturated steam, the steam is at boiling point (212 °F) at atmospheric pressure or higher at increased pressure levels. Because of the relationship between pressure and temperature, steam equipment can increase the boiling point by increasing the pressure.

    Saturated steam is commonly used in pharmaceutical production applications because it can provide rapid but even heating and has a high heat transfer coefficient. Operators can also fine-tune the temperature through pressure controls.

    The Different Types of Steam in Industrial Steam Generation

    Superheated Steam

    Containing less than 1% moisture, superheated steam is another type of dry steam that is hotter than its boiling point at atmospheric pressure. Superheated steam can reach higher temperatures and lower densities compared to saturated steam at the same pressure point. It can also be cooled without returning to liquid form or producing condensate.

    This resistance to becoming liquid makes it an ideal choice for applications like powering the movement of turbines. The steam can move through the nozzles and push the turbine blades, spinning the shaft that generates power, all without presenting the risk of returning to liquid and causing corrosion. It stays ultra-dry throughout its use.

    However, there are some drawbacks to superheated steam. It can have varying temperatures even at a steady pressure and has a lower heat transfer coefficient than other steams. Superheated steam won’t release latent energy until it reaches the right level of saturation. Also, because it does reach such high temperatures, it requires specialized equipment that can handle it.

    Utility Steam

    Utility steam is a type of saturated steam. Most industrial steam processes use utility steam, which contains both latent and sensible energy. Unlike Electro-Steam’s equipment, traditional boilers usually treat feed water with additives that prevent it from corroding boilers or other equipment. This steam is usually classified by low, medium, or high pressure levels. In traditional boilers, utility steam also needs to run through a filter to remove rust, condensate, and other particulates that can contaminate the steam. Even then, utility steam is usually not used in direct contact with products or food but is a means to transfer energy to the relevant process.

    While utility steam is used for boilers and a wide range of industrial applications, it’s not clean enough for culinary, medical, or pharmaceutical needs.

    Culinary Steam

    Culinary steam is regulated by the FDA to ensure any chemical additives designed to prevent rust comply with applicable health and safety regulations. It’s commonly used to sterilize surfaces used in food processing and preparation operations. Along with meeting FDA standards, culinary steam must comply with 3-A Sanitary Standards Inc. (SSI) Accepted Practice 3A-609-03, meet other company-specific policies, and use filtering systems.

    Filtered Steam

    Filtered steam undergoes a filtering process to remove additives or contaminants so it can be more safely used in sterilization applications.

    Clean Steam or Pure Steam

    Clean/Pure steam doesn’t have additives and is produced from heating purified water (RO), highly purified water (DI), or water for injection (WFI). Clean/Pure steam can be used in pharmaceutical, healthcare, and medical contexts.

    Clean steam is generated by systems that use saturated steam, and the resulting condensate can be classified as water for injection, such as saline solutions. Clean steam itself can be used in other various processes such as humidification and sanitation in which contamination cannot be present. Clean steam systems are made from high-grade stainless steel components, piping, and other non-porous materials.

  2. How Do You Clean a Commercial Kitchen?

    Cleanliness is vital in hotel, restaurant, and commercial kitchens. Following proper sanitation guidelines greatly reduces the spread of illness and foodborne outbreaks (foodborne illness outbreaks. However, it can be difficult to understand exactly when and how to clean different areas of a commercial kitchen as this type of space will frequently contain a wide variety of equipment and surface materials.

    Dry steam cleaners sanitize areas without the use of toxic (and harsh) chemicals, making them ideal for commercial kitchens that commonly have various equipment in tight spaces. At Electro-Steam, our commercial steam cleaners can reach temperatures of up to 240° F, well above the 160° F required to kill the majority of pathogens.

    What surfaces should clean steam be used on?

    Commercial kitchen steam cleaners are highly versatile and effective on a wide variety of surfaces, including:


    • Dry steam cleaners are able to scrub (clean) and sanitize the surfaces of grills, flattops, and burners as needed.
    • Countertops and Hard Surfaces. Since these areas frequently come into contact with food, they should be steam cleaned multiple times a day to prevent rapid growth of bacteria.
    • Exhaust Hoods and Vents. These areas should be steam cleaned every few months to eliminate the buildup of grease that could eventually restrict airflow.
    • Kitchen Ceiling and Walls. These areas require steam cleaning at least once a month, although bi-weekly cleaning may be necessary depending on the amount of grease and food particle buildup.
    • Kitchen Floor. Kitchen floors should be cleaned daily as they are prone to the accumulation of food particles, grease, and tracked-in dirt.
    • Ovens and Ranges. These should be commercial steam cleaned weekly, with particular attention to the door, racks, and walls of the oven.
    • Refrigeration Units. Although they may be less exposed to airborne grease and food particles, refrigerator condenser coils and surfaces still require regular steam cleaning (and are often a source of mold and mildew).

    FAQs of cleaning commercial kitchens with steam

    There are a number of questions you may have regarding the use of commercial steam cleaners. We will delve into a few of the most common.

    Can I steam clean wooden kitchen cabinets?

    Wooden surfaces often pose a problem as they can be easily damaged if exposed to the wrong type of cleanser. Fortunately, commercial steam cleaners are an effective method of cleaning wooden cabinets as long as the wood is sealed.

    Can you use a steam cleaner on stainless steel?

    Absolutely—in fact, we highly recommend this. Commercial steam cleaners are an ideal way to clean stainless steel without the use of harsh chemicals.

    What is the best commercial steam cleaner?

    Our TruBlu Dry Steam Cleaners and Electro-Steam Eagle Series are both excellent options. These steam cleaners provide a penetrating clean that reaches every surface, killing pathogens and leaving your commercial kitchen deeply sanitized.
