351NG Key Benefits　

SPI's energy free models are built of polyethylene construction creating a strong corrosion free product to provide many years of trouble free operation.

The polyethylene used in our SPI Livestock Waterers is FDA and HPB approved, food grade, recyclable plastic.  Insulated with polyurethane insulation.  Patented door closure system. 

SPI's energy free models have a set back seal and drain to help counteract the problems associated with door freeze up.  The low profile design and fully hinged door provides animals better access to the capacity of the waterer.  The combination water gasket and foam gasket ensures an airtight seal between the lid and base.  Peaked roof and raised ribs around the door openings prevent manure, feed and other contaminants from being washed into the bowl. Result = cleaner waterer inside and out.  

The waterers are designed with rounded corners to handle livestock abuse while ensuring livestock safety. Our energy free waterers meet "Grade A" Dairy requirements (non-siphoning).
