Helimatic Coolers


 Stewart Systems Helimatic Spiral Conveyor is an endless conveyor system for cooling of bakery



 The Helimatic Cooler features a double spiral design, which minimizes space requirements. Products travel up an outer spiral, and return down an inner spiral. Both the infeed and discharge Stewart Systems Helimatic Cooler - Bun & Bread, spiral cooler, double-helix, high speed, industrial baking, endlesstake place on the bottom tier. This low entrance / low exit design allows the cooler to be easily incorporated into most layouts with minimal conveyor requirements and easy maintenance.


 The Helimatic Cooler is available in a wide variety of sizes and widths, from as small as 18" wide and four tiers high (~374' active feet), to as large as 30" wide and 25 tiers high (~2183' active feet). Multiple coolers can be combined to expand cooling capabilities, if necessary.


 The standard belting is a plated alloy steel wire rod (stainless steel is optional) and is available in both #7 ga. (0.177") and #5 ga. (0.207").


 An open construction permits easy cleaning of the conveyor, and the surrounding areas.


 A variable frequency drive permits easy, accurate regulation of drive motor speed to accommodate production requirements.


 Standard application belt speeds are in the range from 15 to 75 fpm.
