Coldline Refrigerator Master 500 A50/1MR – 1 door, -2/+8 °C, Remote, 417 l

The Coldline A50/1MR is a single-door refrigerator from the Master 500 range, holding -2/+8 °C in a cabinet of 417 litres gross and 290 litres net. In the code A50/1MR, A50 is the 500 body, /1 the number of doors, M the -2/+8 °C range and R the remote refrigeration. As the remote version, the A50/1MR has no condensing unit of its own: it connects to one sited elsewhere through Ø 1/4" delivery and Ø 3/8" suction pipes and runs on R452a, GWP 2,141. Coldline pairs it with the EMT6165GK remote condensing unit in its accessory list. The A50/1MR is one of the Master codes for which Coldline lists a Master Marine solutions variant.

Build and fittings

As supplied, the A50/1MR comes with 3 slides for 42x53 cm shelves, 3 plastic coated 42x53 cm shelves, lock with key, LED lighting. The A50/1MR has a self-closing door with a 105° stop, hinged on the right. Inside and out the A50/1MR is AISI 304 stainless steel, apart from a galvanized/colaminated back, base and technical compartment, with 75 mm of CFC/HCFC-free insulation around 290 litres of storage whose corners are rounded for cleaning. 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. The A50/1MR is run from an electronic control whose display sits flush with the panel.

Cooling and energy

The A50/1MR 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 710 W at 3.3 A, with electric defrost. No energy label is published for the remote A50/1MR, whose consumption depends on the condensing unit it is paired with; a solenoid valve is supplied as standard.

The plug-in A50/1M has the same temperature range but carries its own R290 unit: it weighs 115 kg net against 100 kg for the A50/1MR, and is listed at 220-240 V 50 Hz instead of 220-240 V 50-60 Hz.

Marine version

According to Coldline, the Master Marine section is intended for ships and for oil and floating platforms, where Master refrigeration is combined with marine safety specifications. What is published is the data for the standard A50/1MR. The marine build has no data sheet of its own, and we confirm its details with Coldline before an order. The remote A50/1MR is listed for 220-240 V 50-60 Hz, and other special voltages appear among its variants. Accessories for the A50/1MR include 150 mm stainless steel drawers, bottle shelves, castors, an RS485 serial interface and Cosmo cable or Wi-Fi kits.

Getting it on board

External dimensions of the A50/1MR are 630 × 715 × 2,085 mm (W × D × H) and net weight is 100 kg. In its packing it grows to 835 × 830 × 2,145 mm and 120 kg, which is what has to pass the doors and hatches on the route aboard.
