REFRIGERATING PLANT
Simple—Sanitary—Sure I
N all points of design the Norwalk Refrigerating Plant is ideally adapted to the requirements of private homes, apartments, hotels, hospitals and kindred branches of service. It is distinctively simple, perfectly sanitary, smooth and almost silent in operation; requires no tinkering or adjustments.
The Norwalk is free of internal bolts and. nuts. Its moving parts are few and strong. Valves, bearings and packing are troubleproof, as demonstrated in long tests. It avoids a drawback common to mechanical refrigeration, especially in small machines, by employing semi-fluid graphite for lubrication. This cannot volatilize and reduce efficiency by passing into the refrigerating system.
The simplicity and reliability of the Norwalk, which is of the ammonia compressor type, is due to the fact that the Norwalk Company has had nearly half a century’s experience in the manufacture nf high-quality air
supplied d the full s is availallations.
