Shipping

Alto-Shaam equipment ships from the primary manufacturing facility in Menomonee Falls, Wisconsin, with logistics often coordinated through dedicated Canadian distribution hubs in the Mississauga and Concord regions of Ontario. As a pioneer in Halo Heat technology and high-performance combi ovens, Alto-Shaam units—ranging from Cook & Hold ovens to Vector multi-cook systems—are high-mass, industrial-grade appliances. They are transported via specialized freight carriers on heavy-duty skids to protect sensitive internal electronics, heating cables, and glass components. Every shipment is professionally crated and fully insured to ensure the equipment arrives in factory-perfect condition for commercial installation.

Warranty

Alto-Shaam provides a multi-tiered manufacturer warranty designed to support their specialized heating and cooking technologies in high-utilization environments.

  • Standard Protection: Most Alto-Shaam equipment is covered by a 1-year parts and labour warranty. This coverage remains in effect for 12 months from the date of installation or 15 months from the date of shipment, whichever occurs first.
  • Heating Elements: For units featuring Halo Heat technology, such as Cook & Hold ovens, the heating elements carry a limited lifetime warranty for the original owner. This reflects the durability of the low-density thermal cable design.
  • Refrigeration Compressors: On applicable models like Quickchillers, the refrigeration compressor is protected by an extended 5-year parts-only warranty.
  • Replacement Parts: Genuine replacement parts carry a 90-day warranty from the date of installation.

To validate the warranty, equipment should be registered through the Alto-Shaam online portal within 30 days of installation. All units must be installed by a licensed professional and, for steam-generating equipment, must meet specific water quality standards to maintain active coverage.

Service & Support

Technical service and warranty repairs are managed through an extensive national network of factory-authorized service providers across Canada. Because Alto-Shaam equipment—particularly the Prodigi combi ovens and Vector series—utilizes sophisticated software and precise moisture control systems, all warranty-related service must be performed by authorized technicians. Canadian distribution hubs maintain a comprehensive inventory of genuine OEM parts, including control boards, heating cables, and probes, to facilitate rapid response times and minimize kitchen downtime.

Exceptions & Exclusions

Warranty coverage is strictly contingent upon the equipment being operated and maintained according to the provided manuals. Specific exclusions include:

  • Water Quality: Damage resulting from poor water quality, scale buildup, or a failure to maintain steam generators according to the published maintenance schedule is a primary exclusion.
  • Maintenance Responsibilities: Routine cleaning, calibration, and the replacement of consumable items are the responsibility of the owner.
  • Wearable Items: Consumable parts such as light bulbs, rubber gaskets, air filters, and glass panels (unless damaged during shipping) are considered wear items and are not covered under the primary warranty.
  • Cleaning Agents: Damage caused by using cleaning agents other than those specifically recommended by Alto-Shaam is excluded.
  • Documentation: Freight damage is not a warranty issue; any visible damage to the crate or unit must be clearly noted on the bill of lading at the time of delivery to be eligible for a claim.

About Alto-Shaam

Alto-Shaam has remained at the forefront of the foodservice industry since its founding in 1955. Based in Menomonee Falls, Wisconsin, the family-owned company revolutionized commercial kitchens by inventing Halo Heat® technology, which led to the development of the original Cook & Hold oven. Today, Alto-Shaam is a global leader, providing premium equipment solutions to more than 90 countries while maintaining a core focus on innovation and domestic manufacturing.

The brand’s reputation is built upon its proprietary Halo Heat technology, which utilizes low-density thermal cables to surround food with gentle, radiant heat. This system avoids the harsh temperatures and fans that typically degrade food quality, significantly reducing protein shrinkage and maximizing yields. Integrated into their Cook & Hold ovens and heated holding cabinets, this technology enables "lights-out" overnight cooking, reducing labor and energy costs while ensuring consistent quality in high-volume environments like supermarkets and institutional facilities.

Furthering its technical leadership, Alto-Shaam pioneered Structured Air Technology® to power its Vector® and Converge® multi-cook ovens. These systems feature independent chambers that allow for the simultaneous preparation of diverse menu items with zero flavor transfer. This innovation enables kitchens to air-fry, bake, and steam within a compact, ventless footprint, making it ideal for spaces where ventilation is limited. When paired with the ChefLinc™ remote management system, operators can manage recipes and monitor equipment data across multiple locations for standardized performance.

Alto-Shaam provides comprehensive kitchen systems supported by a robust network of culinary and technical experts. By combining high-performance machinery with cloud-based monitoring and dedicated after-sales service, the company ensures a high return on investment and long-term reliability. Their commitment to sustainable, efficient design makes Alto-Shaam a foundational partner for foodservice operators seeking to optimize their workflow and menu flexibility through advanced thermal engineering.
