The ISA Metro packs a lot of display volume into a small counter and is built for both assisted service and self-service. The served ST RV TN is 1170 mm high and the ST RV CH 1350 mm, while the ST Self comes in both heights; every variant is available 1000, 1300 or 1500 mm wide.
Fan-assisted cooling, off-cycle defrost and double glazing are common to all versions. The glass structure opens downwards and the case has glass sliding doors. Lower models carry two glass shelves and taller ones three.
Standard lighting is 3000 K, optionally 4000 K or 5000 K, and the temperature ranges are −1…+5 °C, +14…+16 °C and +65…+80 °C. Plug-in counters run on R290. Remote counters use R452a and need a separately sourced condensing unit, as none is supplied.
The compressor is hermetic, the climate class is 3 (+25 °C, 60% RH) and the cabinet is white RAL 9003, standing on height-adjustable feet with braked swivel castors available.
