LOW TEMPERATURE WARE WASHING

The National Sanitation Foundation (NSF) in the USA, and most health codes define low temperature ware washing (flat ware, frying pans, etc.) as a wash cycle using 49 - 60C water in combination with a chlorine based dish wash. One reason for using low temperature ware washing is the energy savings that can be accomplished. Typical energy costs for dish wash operations can account for 7% - 25% of a kitchen's total energy usage. Consequently, a 30% - 70% reduction in energy cost is achievable through low temperature operations. We have the product, 4-CLOR, which will meet your needs for low temperature ware wash applications.

CLEANING AND DISINFECTION

Chlorine, iodine and quaternary ammonium chloride compounds are all effective disinfectants and sanitisers, when used in proper concentration and given enough time to act. In locations where organic soil levels are high, the choice of products depends on whether the product is capable of handling the organic soil load. Our products like Arrest and Safe! are formulated with detergents added so as to remove some of the organic soils present. A product that disinfects only, like First Mate, which is used in food processing accounts, often requires the use of a companion product like Klor Star or Ensign. These are used prior to sanitising to remove the organic soil load so that First Mate will perform more effectively on the surface to be sanitised, providing the hygienic conditions so important in food handling areas.

REST ROOMS

Rest rooms are among the most important areas to keep clean. No matter how spotless the rest of the facility, a dirty or smelly restroom will affect the appearance of the entire facility. To consolidate customers' needs, we recommend Safe! and Arrest. Both products clean and disinfect the bathroom surfaces in one step, saving the extra expense of additional cleaning product, and the additional time required to use several products.

COOLING TOWER FREEZE PROTECTION

Glycols are used in many closed systems and also in some cooling towers for freeze protection. The two most widely used are ethylene glycol and propylene glycol. Both types of glycol are compatible with all of our AquaTrol closed loop corrosion inhibitors. It is recommended that an inhibitor be used to control corrosion whenever using a glycol antifreeze.

ADDITIVES IN OUR LUBEST LUBRICANTS

The additive, Flexol/Flexol A, provides anti-wear properties to our Lubest lubricants. Anti-wear additives react with metal surfaces to produce a protective film on the metal. This film has a lower shear strength than the metal, so when boundary lubrication conditions occur (i.e. metal actually touching metal) this protective film is sacrificed instead of the metal itself. Anti-wear additives are most useful under high speed or moderate loading conditions. The benefit of a lubricant formulation containing Flexol/Flexol A is less wear on machinery, lower downtime for maintenance, and fewer spare parts for stock.

Extreme pressure (EP) Lubest additives, like TK-75, operate similarly to anti-wear additives in that they react with metal surfaces to produce a protective film on the metal (see above). This film also reduces friction. The difference between the two additives is in the temperature of activation. Anti-wear additives operate at room temperature. EP additives, however, do not begin to work until they approach 550C. TK-75 is found primarily in our gear oil formulations because this extremely high temperature is reached when the gear teeth mesh and slide against each other. The combination of pressure and sliding friction is able to generate (in this localised area) the necessary temperatures to activate the additive. TK-75 is also responsible for giving oils their characteristic smell as it contains sulfur and phosphorous.

The Lubest additive Moly DSD is a stable suspension of molybdenum disulfide. It is a solid lubricant that has the ability to coat and fill in the pores of metal by physically attaching itself to the metal. By doing this, Moly DSD provides a protective layer that offers several advantages to a gear oil:

Reduces Friction and Wear -- which reduces energy use, reduces operating temperatures, smoothes operations, and prolongs equipment life.

Increases Extreme Pressure Properties -- which increases load carrying capacities, protects equipment subject to shock loading, and reduces chances of galling, fretting or seizure.

Provides Boundary Lubrication -- which protects equipment even when the oil film breaks down.

Because Moly DSD can be aggressive towards some metals (mostly some types of brasses and bronzes) it is only found in our product, Opal, which is a Severe Service Gear Oil. The Original Equipment Manufacturer's (OEM) guide will tell you if molybdenum disulfide additives cannot be used.
