Refra's stand combines black suspended signs reading "Green by choice, safe by design" with green mesh curtains and circular cages of black rods around meeting areas. At the front stand two white units labelled "Propane Chiller" and "Propane Heat Pump", their side doors open to show green-lit internal components and piping.
