SANS 10147

SANS 10147 which is the governing refrigeration legislation within South Africa, has specific requirements for all refrigeration plants. One of the requirements is a P&ID (piping and instrumentation diagram) drawing outside the plantroom indicating critical (emergency) requires the following:

6.13.3 Metal signs

Refrigerating systems that contain more than 500 kg of refrigerant shall have metal signs, which have letters of height at least 20 mm, to designate the isolating shut-off valves to each vessel, the main stream control or the electrical control, the remote control switches, and the pressure-limiting devices installed outside the refrigeration plant room.

A schematic drawing of the plant shall be mounted outside the plant room clearly identifying all of the numbered critical isolation valves in the system. All exposed high-pressure and low-pressure piping shall bear signs with the name of the refrigerant, the medium in the pipes, its direction of flow, and the letters “HP” or “LP”.

All mandatory safety, first-aid and emergency procedures, and plant signs shall be mounted on metal plates in a clearly visible position outside the plant room.

Whether it is supermarket design, refrigerated cabinets or polyurethane insulated rooms, we can conscientiously complete any task at hand.

As we’ve stated earlier, efficient and completely functional commercial refrigerators are essential for retailers, restaurants, and a variety of other enterprises to provide consistent service and achieve success.
