TECHNI-TIP: Improving Oven Chain Lubrication

CUSTOMER TESTIMONIAL: 2700 Almasol Oven Chain Lubricant




Lubrication Engineers' commitment to continuous product improvement has resulted in the re-formulation of its oven chain lubricant. 2700 Almasol has been upgraded to incorporate a new, more environmentally friendly carrier, with a greater capability to suspend solid particles. The new 2710 ALMASOL promotes smooth, long-lasting operation regardless of extreme heat and high moisture conditions. Benefits of the upgraded product include:

- Environment Friendly: The new USDA H2 approved lubricant features a biodegradable, water soluble carrier fluid that evaporates readily and is nearly odourless. The new formulation eliminates accumulation of carbon particles, gum or other hard deposits.

- Protection: 2710 is formulated with a synergistic blend of lubricating solids, including submicron-sized ALMASOL particles, to reduce wear by completely penetrating into the pin and bushing area. It resists corrosion by sealing out damaging moisture and shielding against acid attack.

- Performance: As the carrier dissipates, the solids protect the chain up to 482 degrees Celsius (900 degrees Fahrenheit); ensuring quiet, smooth operation by thoroughly lubricating middle joints and strands, enabling them to move freely.

TECHNI-TIP: Improving Oven Chain Lubrication

By Jeffrey E. Turner, Executive Vice President, Lubrication Engineers, Inc.

Oven chains operating at high temperatures can be lubricated in two different ways: with a liquid lubricant, or with a solid lubricant suspended in a carrier fluid. Whether solid or liquid, the lubricating film physically separates contacting metal surfaces, thereby reducing friction and wear.

Fluid Film Lubrication
Fluid film lubrication is the regular oil film lubrication used in most ambient temperature applications. This type of lubrication can also be used at higher temperatures, provided that you take into account the decreased viscosity of the fluid (thinner oil film), the increased oxidation rate of the oil (can leave varnish and sludge), and the volatility of the oil (as it evaporates, there is less oil with which to lubricate).
A variety of synthetic base oils (polyalphaolefins (PAO), esters, silicones) enable lubrication at higher temperatures than petroleum oils. They have the same limitations (thinning out, oxidizing and evaporating) as petroleum oils, just at higher temperatures.
At higher operating temperatures, frequent lubrication is required to replace the fluid lost to evaporation. The evaporation, oxidation and decrease in viscosity make proper lubrication difficult to achieve with a liquid lubricant alone. In such cases, using a solid lubricant provides better wear protection and consumes less lubricant.
Solid Film Lubrication
Solid film lubrication is used at high temperatures or in applications where it is impossible or undesirable to use a liquid. The solid is usually suspended in a liquid carrier designed to disperse (evaporate) after the lubricant has been applied and in the case of chains, after it has penetrated in to the pin area of the chain. The example that most people are familiar with is graphite powder dissolved in kerosene, but technology has advanced well beyond this.

"Amperage Spikes Have Been Eliminated, and Oven Chain Life Has Been Prolonged Significantly Past Manufacturers Expectations"

Gilda Industries make Cuban style crackers in Hialeah, Florida. They distribute their product worldwide and are now the largest manufacturer of Cuban style crackers in the world.
Gilda Industries uses a Baker Perkins conveyor oven to manufacture their crackers. Several years ago, while using commercial grade oven chain oil, they noticed spikes in the amperage readings of the motors powering the conveyor chain. This is a sign of the chain pulling and slacking which can lead to premature wear and excessive electricity usage.

LE Lubrication Consultants recommended 2700 ALMASOL Oven Chain Lubricant due to its ability to penetrate completely into the pins and bushings of the chain and its ability to withstand heat up to 900 degrees Fahrenheit (482 degrees Celsius) without oxidizing. After converting to LE 2700, the amperage reading on the motors powering the chains remained steady. The oven chain has also lasted well over ten years, substantially longer than Baker Perkins suggests. Chief Engineer Rony Garcia stated, "The fact that we are still using the original oven chain is a testament to the performance of 2700 ALMASOL Oven Chain Lubricant."
