Industrial Water Heaters

Sioux's high-efficiency industrial water heaters are among the most efficient on the market today. Sioux water heating systems provide a continuous hot water supply without preheating and no recovery time. The operation is simple. A 100°F temperature rise can be reached in only 3-5 minutes (depending on the unit rating). Outlet temperatures and flow rates can be held at precise levels. Commercial and industrial hot water heating systems are pre-plumbed and pre-wired for easy installation. Diesel, LP, or natural gas; or a combination burner that will burn any of the above fuels.

If a fuel fired model is not possible, Sioux can manufacture 100% electric water heaters including either a 360-gallon or 1000-gallon water storage tank. These models can include a tank discharge pump to meet your process application needs. Because they are all-electric, a 3-phase electrical source is required for operation.

Applications

For over 50 years, Sioux has manufactured water heaters that are used in a variety of industries such as:

Concrete Production
