Self Contained Ref. System (All In One, Plug and Go)
These systems are all-encompassing in one main insulated metal box, they have the evaporator, the accessories and the condensing all included inside the one insulated metal box, most of the systems bring their own plug cord and all you have to do is plug the cord into an electrical outlet depending on the required voltage and amperage and set the temperature controls and go, there is no need to pre-charge the system with Freon or do any type of plumbing, it’s all inclusive. The air inside the walk-in is drawn up through the evaporator coil located within the insulated metal box housing, the self contained refrigeration systems sits on top of the walk-in through a factory made and finished ceiling cutout. A licensed refrigeration technician may be needed to fine tune the refrigeration system. These systems will sometimes seem to have a higher in upfront cost but when all things are considered your cost for installing a split refrigeration system versus these self contained refrigeration systems will be much less because the self contained refrigeration system is factory assembled, does not take up space inside the walk-in and it is less expensive in the long run.
