In 1900s, delivery of milk use horse and buggy and no means of refrigeration at all to customers in the city and close to the dairy. The next 50 up to 60 years, delivery of milk use Chevrolet C40 heavy truck with AC Condensers.

Chevrolet C40 – 72 was combined with modern truck chassis by Chevrolet known as a “Flat Face Cowl” chassis. These refrigerated truck bodies usually had three inches of insulation on the sides and 4 inches on the ceiling and floor area. The sliding doors in the driver area were designed to be easily opened and closed in a sliding manner.

The refrigeration of these bodies was by a compressor that you plugged in at night and it ran to freeze “cold hold plates” that acted as large ice cubes during the day to keep the milk products cold when operating the door openings properly during delivery.

Staying cool and cozy inside your Chevrolet C40-72 Series Heavy Truck during the summer is easy nowadays. Just furnish your truck with a heavy-duty air conditioning system and you are well on your way to achieving unmatched driving comfort.
