Cold room with shelving and ceiling-mounted evaporator

Cold rooms and industrial refrigeration

In the cold chain, where product loss is measured in hours, we keep condensing units, evaporators and control systems running without interruption.

In shortA cold room is an insulated room where food, pharmaceuticals and similar products are stored at a set temperature; it consists of a condensing unit, an evaporator and a control panel. YOİ Mühendislik builds cold rooms and services condensing units, defrost and control faults, supermarket display cabinets and process cooling.

About cold rooms and industrial refrigeration
