Reduce CO2 Emissions Economically

Companies and organizations of every size, in every industry and on every continent are turning to ORC – Organic Rankine Cycle systems. Converting low temperature heat to energy is good business and good for the environment.

Solstice zd (R-1233zd) and Genetron 245fa are proven working fluids in Organic Rankine Cycle systems. Whether used in waste heat recovery for geothermal industries, power generation systems, industrial processes or transportation, ORC systems that use Honeywell’s working fluids increase the amount of clean energy and reduce CO2 emissions. ORC systems using Solstice zd or Genetron 245fa can deliver better energy efficiency, improving your return on ORC investment.

Genetron 245fa thermodynamic properties reduce ORC size and costs, lowering your capital investments. If you’re facing high electric rates or growing demand charges, ORC with Genetron 245fa working fluid offers both a solution and an opportunity.

Solstice zd and Genetron 245fa are nonflammable, which can lead to substantial reduction in end user investment costs compared with flammable alternatives.

Product Name ASHRAE # Product Description
Solstice®zd R-1233zd Solstice® zd is a non-flammable, ultra-low GWP replacement for R-123 for low pressure centrifugal chillers. It has a GWP of 1 which is 99.9% lower than R-245fa, making it an environmentally preferable alternative in applications such as Organic Rankine cycle (ORC) and high temperature heat pumps.
Genetron® AZ-50® R-507 A non-ozone depleting azeotropic mixture of HFC-125 and HFC-143a. It has been primarily designed to replace R-502 in low- and medium-temperature commercial refrigeration applications such as supermarket display cases and ice machines. For new equipment and retrofits.
Genetron® 245fa R-245fa A non-ozone depleting candidate replacement for CFC-11 in centrifugal chillers. For new equipment.
Genetron® 134a R-134a Replaces CFC-12 in auto air conditioning and in residential, commercial and industrial refrigeration systems. For new equipment.
Genetron® AZ-20® R-410A Widely accepted to replace HCFC-22 in air conditioning and refrigeration applications. For new equipment – not for retrofits.
