Indel B medical line temperature controlled fridge with built-in isothermal containers designed for installation and use inside ambulances. FM7 TOP is a controlled temperature compressor refrigerator for the storage and transport of drugs. The fridge is designed to reach and maintain a temperature of 4°C with a tolerance of +/-1.5°C. The thermostat allows you to set a specific temperature in a range from 2°C to 8°C. If the set temperature varies by more than +/-1.5°C, two alarms will be activated: an acoustic alarm (buzzer) and a visual alarm (red flashing LED). Both alarms will remain active until voluntarily reset by the health operator or through the procedure indicated in the guide. The refrigeration unit is remotely-controllable for maximum installation flexibility. As due to its size and the fact the compressor can actually be moved from the top to either side of the unit and it’s incredible cooling efficiency. (2 or 3 °C) It was an easy choice. I found standard 12v fridges to be useless for what I needed it for. This fridge keep a constant temperature with the digital display on the front all day. (Obviously with its medical use that’s what’s it’s designed to do) The fridge was taken into a local company to be fully tested with the refrigerant renewed ready for this sale. So if it’s medical use or leisure use this fridge is in perfect working order please note the inner metal shelf is missing from this sale.
