ALTERNATIVE OPTIONS FOR PLUG-IN, SMALL COMMERCIAL

CABINETS IN HIGH AMBIENT AREAS…

SOUTHERN AFRICAN REGION

by Roy Singh

SELF CONTAINED REFRIGERATED CABINETS…

These products are produced in low volumes - high refrigerant usage .

1. Integral condensing unit2. HCFC to R600a/R290/R7443. Charge < 150g for HC4. Twin circuit for larger cabinets

“ Plug & Play “

Challenges… ProductMostly Independent companies -System redesign – Insufficient

technical know how, no partner collaboration as in large multinational companies. Local R&D engineering team .

Compact design (cassette) – Electrical components and refrigerant in close proximity. SOI - Leak simulation test critical – Expensive test equipment. Tested at production facility.

Testing – IEC 60335 & CE - Limited locally equipped test house

Production machinery & Product Support

High cost of safety/ventilation/charging equipment – less complex machines for lower volume batch production.( < 48kg HC )

Availability of Refrigerant ,Spares & Components for replacement in remote areas .

Training &Technician Certification. Not same as domestic refrigeration techs which were trained- totally different cluster.
