In the current issue of Perishable News, Bakery Highlights, the publication notes that hi-temperature RTH wheels are needed most in the food processing industry and these unique wheels and casters allow for Operating Temperature Ranges of -40°C (-104°F) to +260C (+500°F).
Traditional wheels do not work in hi-temp bakeries. Bakeries roll carts into ovens. Traditional hi-temp phenolic wheels survive about 350-400°F intermittent temperatures (30 mins in/30 mins cool-off). The traditional wheels are hard and noisy when rolling on the bakery floors. The wheels run directly on the caster axle without lubricant; they squeak when in higher temperatures.
An ergonomically friendly work environment requires noise reduction. RTH wheels are a special proprietary high temperature aerospace rubber compound that cushions the loaded racks from vibration, reduce floor noise, and can be equipped with special noise eliminating bearings. The RTH wheels and the stainless steel casters available from Magnus Mobility are FDA/USDA approved for contact with food ingredients and are permanently lubricated with FDA approved, non-toxic lubricants.
The RTH wheel has no odor when used in bakery hi-temp food processing applications;
Frozen foods manufacturers find benefits from the RTH wheel because frozen foods are partially prepared. That means they are often cooked or baked to some degree, then flash frozen for packaging. The RTH wheel can withstand, and is guaranteed within its operating range, huge environmental temperature swings quickly. Traditional casters and wheels usually fail relatively quickly in this situation.
