Customizable Heating Maintenance on Heat Exchangers

Customizable Heating Maintenance on Heat Exchangers

heat exchangersAmerican Services industrial heating maintenance near Sunset Hills knows that your heat exchanger requires routine maintenance to ensure proper and efficient heating. Having a customizable preventable heating maintenance plan will ensure your system stays online with little downtime, reducing the number of repair calls increases productivity in your operation. Heating is a necessity in most operations and system malfunctions just cause headaches.

Many heat exchangers are identified as CIP, clean in place. CIP cleaning is a condition that the scaling on the plates is soluble. All materials in the entire circulation system of course have to be resistant to the cleaning detergent. You don’t want to use an improper cleaning agent and risk damaging your heating system. If the solution requires recirculation, select a flow that is as high as possible, and no less than the service or product flows. Most detergent suppliers and cleaning specialists will provide instructions for their products. Typical circulation time of cleaning agents should be no less than 30 minutes. Always rinse away the cleaning agent thoroughly with fresh water and circulate fresh water for at least 10 minutes.

If the plates require a physical cleaning, use nylon or other types of “soft” scrubbing brushes with detergent. Never use a metal brush, steel wool or sand/glass paper as it will damage the passivation film of the plates. Typically acetone or other types of solvents which do not contain chlorine are used to remove old gasket glue. When using detergents, they should be compatible with the plate and gasket material before use. It is always wise to consult a cleaning specialist for information and recommendations specific to your application.

Repair of Commercial Refrigeration Systems

Repair of Commercial Refrigeration Systems

commercial refrigeration service in MOThe first industries to use commercial refrigeration on a large scale were Breweries in the mid to late 1800s.

Although technology has changed tremendously over the last 150 years, the theory and concepts behind commercial refrigeration remain the same.

The early breweries  depended on harvesting large blocks of ice whereas nowadays we utilize artificial refrigeration.  Today, many industries, large and small, utilizes refrigeration units of all sizes.

Commercial refrigeration systems are paramount to ensure your refrigerated products are kept out of the danger zone.  System malfunctions can lead to large scale product loss and expensive repairs.  Repairing commercial refrigeration systems can be an unexpected expense that challenges the productivity of your industry.  It is always good practice to have a plan of action given a refrigeration system malfunctions.

Regular maintenance can reduce the need for frequent commercial refrigeration repair. Many of the regular refrigeration maintenance tasks can be performed by anyone.  These include; checking conditions of door gaskets, monitoring temperatures, inspecting door hinges, and checking or adjusting defrost timers.  Other refrigeration maintenance, such as overseeing compressor operation and control wiring, should be conducted by a certified technician such as those at American Services commercial refrigeration repair in Missouri.

There will be times that refrigeration systems will fail.  Seeking a reputable, experienced, dependable refrigeration service company is essential to ensuring minimal productivity and product loss.  Be sure to ask for references of other clients and contact them to ensure the company you select will complete the work in a timely, professional manner.   When the technician arrives, ask about preventative maintenance tasks or procedures that can be performed to prevent future issues or problems.

Commercial Cooling System Erosion

Commercial Cooling System Erosion

cooling installation in MOAmerican Services cooling system installation in Chesterfield know that experts in the cooling system industry estimate that about 40 percent of down time is caused by cooling system maintenance problems. Researching and Understanding the common problems and implementing proven preventive maintenance practices will significantly reduce your operating cost. The four major problems associated with commercial cooling system breakdown and malfunctions are:

– Corrosion
– Cavitation-erosion
– Scale deposits
– Green-goo or drop-out
Corrosion what is it? Corrosion is the natural tendency of metals to revert back to their ore form; an example is cast iron oxides which will form reddish brown (commonly known as rust) deposits on engine services.

Similarly other metals form oxides. The color of the various corrosion events can vary from white to black depending on the specific oxide that has formed.

There are a variety of conditions in a cooling system environment which will affect the degree and rate at which metal surfaces corrode. Because these conditions are “generally present in all commercial cooling systems” this enables certified cooling system technicians such as those at American Services, to routinely perform preventative maintenance operations on many systems. These conditions include coolant Ph., which is simply the concentration of dissolved oxygen and carbon dioxide in a coolant, metal surface deposits, metal stress, coolant temperature, and acids formed in a combustion process of the fuel and the corrosion inhibitors present. To one degree or another of these conditions are present in “almost all commercial cooling systems,” once maintenance staff understand this, cooling system malfunctions like corrosion can be detected easily and early enough to prevent serious deterioration.

Under certain conditions all metals in the cooling system will corrode. Metallurgy science proves some metals are more sensitive than others, when metals corrode they weaken as a result, components fail. Aluminum is the metal most prone to corrosion in a cooling system environment, others include cast iron, solder, steel copper and brass to a somewhat a lesser degree will also corrode.

To reduce corrosion in your commercial cooling system a good corrosion inhibitor is a must.

Corrosion inhibitors should contain the following critical components
-pH buffer this will help maintain optimum coolant pH levels
-Silicate is the best known corrosion inhibitor for aluminum services
-TT and MBT Chemical inhibitors for protection of copper and brass
surfaces
– Phosphate, Borate and Nitrate, the best corrosion inhibitor for iron, steel and aluminum.

These corrosive inhibitors are the simplest solution to corrosion problems.
