Multinational HVAC&R giant Danfoss has named Welbilt brand Delfield – one of the largest custom stainless steel refrigeration equipment manufacturers in the world – the winner of its EnVisioneer of the Year award for its use of Danfoss controls to covert equipment to natural refrigerant propane while significantly improving energy efficiency.
In late 2016, Florida-based foodservice equipment manufacturer Welbilt finished converting its Delfield upright and under-counter commercial refrigeration display cases to propane (R290) from R404A. In addition to meeting the U.S. Department of Energy's mandated 2017 efficiency requirements, many of the propane cases meet the even stricter (though voluntary) 2017 ENERGY STAR 4.0 efficiency standards set by the U.S. Environmental Protection Agency.
Delfield is harnessing Danfoss thermostatic expansion valves and electronic controls to optimise its foodservice refrigeration equipment. Welbilt, based in New Port Richey, Fla., unveiled its Delfield R290 units at the NAFEM Show in Orlando, Fla. in February, having completed the conversion of those units late last year.
“This is a great example of how innovative engineering can put ambitious energy-efficiency and refrigerant targets squarely in reach – without compromising performance or reliability,” said John Gaylen, president, Danfoss North America.
“Danfoss applauds Delfield for its commitment to advancing the industry through environmentally friendly, energy-efficient technologies.”

Switching from R404A to R290 reduced the global warming potential of the Delfield equipment by more than 99%, from 3,943 to three. The switch resulted in a 40-80% lower refrigerant charge and slashed energy consumption by as much as 50%, further reducing the equipment’s environmental footprint.
“This recognition is a testament to our commitment to deliver high-quality commercial foodservice equipment while simultaneously helping improve energy efficiency and reduce greenhouse gas emissions,” said Josef Matosevic, chief operating officer, Welbilt.
Launched in 2010, the EnVisioneer of the Year award recognises North American end users, municipalities, building owners, and OEMs that have introduced a new product, opened a new facility, or invested in a building or system upgrade using Danfoss products to deliver significant energy or environmental savings.
“We are truly honoured to receive the EnVisioneer of the Year award from Danfoss.”
