Lessons Learned & Insights
UNIDO
Regional SA Ozone Network Meeting
Agra, India
25 May 2017

2. CONTENTS
Status of implementation in the XPS, RAC manufacturing and PU foam manufacturing sectors
Technical and Policy Challenges for achievement of 2020 HCFC Phase-out Targets

3. XPS MANUFACTURING SECTOR -STATUS
29 production lines for conversion to either CO2 or butane or butane mixed with other low GWP blowing agents
10 enterprises converted and introduced CO2 technology
10 enterprises prepared for commissioning
Additional technical assistance
improvements to the standards for XPS foam products
optimization of the CO2 technology
good practices for safe production of XPS foam using the CO2 technology

4. XPS MANUFACTURING SECTOR - CHALLENGES
Further improvements needed on thermal conductivity, dimensional stability and flame retardancy
Enterprises to use virgin materials, instead of recycled materials in order to stabilize the manufacturing process with CO2 technology
Safety considerations necessary due to the introduction of flammable chemicals as co-blowing agents
Use of brominated flame retardant controlled by the Stockholm Convention

5. XPS MANUFACTURING SECTOR – ACTIONS TAKEN
Research on optimization of the CO2 and ethanol technology
Use of carbonate nucleation agents in XPS foam production
Testing of secondary expansion foaming and horizontal vacuum foaming
Testing of alternative flame retardants
Update of book on safe XPS production with CO2 technology
Training workshops on safe XPS manufacturing
Assist to achieve time-limited exemption for use of HBCD under the Stockholm Convention

6. RAC MANUFACTURING SECTOR - STATUS
Demonstration projects on split units and compressor production
HPMP stage I (2011 – 2016)
13 split lines converted
8 RAC and 3 compressor lines converted
Standards for flammable refrigerants
Research on risk assessment of leakage and performance optimization

7. RAC MANUFACTURING SECTOR -FUTURE
HPMP stage II (2016 – 2021):
25 RAC manufacturing lines to be converted to R-290 or R-161 (include 5 lines heat pump water heaters to R-744)
4 compressor lines to be converted to R-290 or R- 744
Technical assistance to facilitate technology introduction and support for the conversions

8. RAC MANUFACTURING SECTOR - CHALLENGES
Substantial growth since 2009 (equivalent to 64 % of the total RAC units production)
Conversion projects require a commitment to phase-out equivalent R-22 production capacity
Rapid growth of residential HPWH
Restrictive standards
Charge limitations
Installation and after-sales service

9. RAC MANUFACTURING SECTOR -ACTIONS TAKEN
Active cooperation with beneficiary industries on standards revision
Research undertaken as part of HPMP on charge distribution; maximum leakage; compressor HX design
How to handle larger A/C’s; i.e. larger than 2 TR?
Installation initially through authorized service companies
Informal after-sales still needs to be addressed

10. ASSISTANCE TO PU FOAM SECTOR
Conversion of PU foam manufacturers (sandwich panels, block foam)
Conversion of local systems houses
Conversion of spray foaming companies
Technical assistance to smaller PU foam manufacturers (other than spray foam)

11. PU FOAM PANEL MANUFACTURERS –PROGRESS
16 PU foam machines in West Asia
6 machines commissioned (2 conti, 1 disco, 1 block foam, 2 machines for RAC manufacturing)
6 machines waiting for installation and commissioning (2 conti, 3 discontinuos, 1 blockfoam)

12. PU FOAM PANEL MANUFACTURERS - CHALLENGES
Compliance with national civil defense regulations
Compliance with national building code standards
Compliance with existing customs clearance procedures
Competition with conversion to high GWP options (not supported by HPMP)

13. ASSISTANCE TO SYSTEMS HOUSES - STATUS
7 eligible systems houses in West Asia
2 consultation workshops in March 2014 and December 2014
Only one SH was ready for conversion
Assistance for conversion to production of pentane pre-blended in polyol (on-going)
4 other SHs now ready for conversion to systems based on new low GWP blowing agents

14. ASSISTANCE TO SYSTEMS HOUSES - CHALLENGES
Possible interventions
Upgrading existing mixing devices with safety systems
Provision of laboratory testing equipment
Storage area temperature control (eligibility?)
Cost effectiveness of available low GWP alternatives
Synchronization of SHs conversion with conversion of their downstream clients
Competition with systems based on HFCs and with imported systems with 141b

15. ASSISTANCE TO SPRAY FOAMERS - STATUS
Numerous eligible spray foaming companies in West Asia
Assistance in KSA delayed by the ExCom decision

16. ASSISTANCE TO SPRAY FOAMERS -CHALLENGES
Eligibility of ICC for new low GWP alternatives (temperature control needed to control viscosity and shelf life of low GWP systems)
Cost-effectiveness of systems based on low GWP blowing agents
Competition with systems based on HFCs due to current price and availability
Competition with import of pure/pre-blended HCFC- 141b in the West Asia region

17. SMALL PU FOAM MANUFACTURERS - STATUS
More than 100 eligible small foam manufacturers in West Asia
Assistance to be provided through local systems houses
Technical support for technology transfer, funding of localized trials and testing

18. SMALL PU FOAM MANUFACTURERS - CHALLENGES
Assistance to be provided separately for each systems house due to commercial sensitivity of information about SH’s clients
Design series of training workshops for SHs and their clients
Assist systems houses with pilot-scale facilities for demonstration of customized formulations based on low GWP blowing agents

19. OPPORTUNITIES Recently approved demonstration projects
Demo project on use of HFO in the spray foam applications
Demo project on HFO-based prototypes for window and packaged AC in KSA
PRAHA-II will facilitate development of window A/C with R-290
