The A50/1NR has a self-closing door with a 105° stop, hinged on the right. A 75 mm insulated single body in AISI 304 stainless steel, with galvanized/colaminated back, base and technical compartment, encloses 290 litres of storage with rounded inner corners. Its magnetic triple-chamber gasket can be replaced, the handle is 2 mm AISI 304, and the AISI 304 feet adjust between 100 and 150 mm under the 2,085 mm high cabinet. Temperature, 0/+10 °C, is set on an electronic control with the display flush to the panel.

Cooling and energy

The A50/1NR has a rated cooling capacity of 448 W (evaporating at -10 °C, condensing at +55 °C). On 220-240 V 50-60 Hz it draws 220 W at 1 A, with automatic off-cycle defrost. No energy label is published for the remote A50/1NR, whose consumption depends on the condensing unit it is paired with; a solenoid valve is supplied as standard.

Marine version

Coldline builds the Master Marine section for installation on ships, oil platforms and floating platforms, pairing the Master series' refrigeration with the safety specifications vessels require. Coldline does not publish a separate data sheet for the marine build, so the data here is for the standard A50/1NR and the marine specification is agreed with Coldline at quotation. The remote A50/1NR is listed for 220-240 V 50-60 Hz, and other special voltages appear among its variants. Accessories for the A50/1NR include 150 mm stainless steel drawers, bottle shelves, castors, an RS485 serial interface and Cosmo cable or Wi-Fi kits.

External dimensions of the A50/1NR are 630 × 715 × 2,085 mm (W × D × H) and net weight is 100 kg. In its packing it grows to 835 × 830 × 2,144 mm and 120 kg, which is what has to pass the doors and hatches on the route aboard.
