CFC-11 and HCFC-141b Phase-out in the foam sector
Islamic Republic of Iran is a signatory of the Montreal Protocol and therefore is committed to phase-out 570 tonnes of HCFC-141b by 1st January 2015. HCFC-141b is an Ozone Depleting Substance. To reach this goal, the United Nations Industrial Development Organization (UNIDO), as one of the implementing agency, is assisting fifteen selected enterprises to take the necessary measures for the phase-out 291 tonnes of HCFC-141b as well as providing them with financial and technical support. GIZ, a German NGO is in charge for phasing out the remaining 279 tonnes.
The enterprises that have not previously undergone conversions (from CFC-11 and CFC-12) by the Multilateral Funds for the Implementation of the Montreal Protocol are prioritized over second conversion. The remaining HCFC-141b consumption in eligible manufacturing enterprises would be addressed until 2030, when the consumption is planned to be reduce to zero.
“Golasaye Sarma” Company is one of the major domestic refrigerator and refrigerator-freezer manufacturers in Iran producing 30 to 50 thousand units per year with a consumption of 109 tons of HCFC-141b in.
The company is amongst the selected companies in the foam industry to receive technical and financial support from UNIDO for the phase out process. The decision has been made by the company board of directors that the HCFC-141b would be replaced by Cyclopentane.
What is Cyclopentane?
Cyclopentane is a blowing agent for the manufacture of polyurethane insulating foam, as found in many domestic appliances such as refrigerators and freezers, replacing environmentally damaging substances such as CFC-11and HCFC-141b.
The advantage of using Cyclopnetane is that it has no effect on Ozone Layer or Global Warming and the price is three times cheaper than HCFC-141b.
The disadvantage however is that the substance is highly flammable so the manufacturing area needs to be modified, including an effective ventilation systems and security sensors in place.
