Refrigerator / Freezer Insulation

Honeywell Leads the Way

Honeywell is the global leader in the development and production of high performance rigid foam blowing agents for refrigerator and freezer manufacturers worldwide.

Working closely with our customers, we’re advancing non-ozone depleting, nonflammable liquid blowing agent technology. We are committed to developing foam blowing agents that continually lower global warming potential (GWP) while increasing energy efficiency and insulation performance.

Low Global Warming Potential Foam Blowing Agent

Global attention to climate change led us to develop the fourth generation Solstice® Liquid Blowing Agent (LBA). It is a low global warming potential (GWP), nonflammable, energy-efficient foam blowing agent for refrigerator and freezer insulation applications.

In refrigerator trials, units made with HFC-245fa were 8-10% more energy efficient than those made with cyclopentane, and units made with Solstice LBA were 2% more energy efficient than those made with HFC-245fa (in an unoptimized system).

In an optimized system we expect that refrigerators made with Solstice LBA will demonstrate even better energy efficiency performance.

Some benefits for refrigerator and freezer OEMs include:

  • Low GWP
  • k-factor performance 4-5% better than 245fa
  • k-factor performance 12-15% better than cyclopentane
  • Nonflammability
  • Low toxicity
  • Energy efficiency that exceeds U.S. Department of Energy (DOE) Energy Star requirements
  • VOC-exempt

Solstice LBA refrigerators exceeded the (proposed) DOE 2014 Energy Standard, without additional solutions like vacuum insulation panels or compressor modification.

Trials are ongoing with appliance OEMs. Contact us to learn more about Honeywell Solstice LBA.

Proven Performance

Enovate 245fa is a non-ozone-depleting, nonflammable liquid blowing agent offering outstanding insulation performance for refrigerator and freezer applications. Many leading refrigerator and freezer manufacturers worldwide have switched to Enovate blowing agent, and benefit from its proven performance advantages.

With a focus on improving refrigerator and freezer energy efficiency, Enovate provides superior insulating characteristics, long-term performance and excellent compatibility with plastic liners. Enovate is the preferred foam blowing agent for OEMs seeking proven reliability and improved environmental performance.

Enovate (HFC-245fa,1,1,1,3,3 – pentafluoropropane) is a proven replacement for HCFC-141b and other fluorocarbon and non-fluorocarbon foam blowing agents. The U.S. EPA has given SNAP approval for the use of Enovate as a replacement in all foam applications.

Some benefits for refrigerator and freezer OEMs include:

  • Non-ozone depleting
  • 8-10% better K factor than cyclopentane formulations
  • Nonflammable
  • Superior cold temperature insulation performance
  • Outstanding long-term insulation performance
  • Compatible with commonly used plastic liners
  • Non-VOC (U.S.A)
  • Low toxicity
