History

Our background in ammonia refrigeration had its beginning with C.P. Wood, Sr. who started in the industry at the age of fourteen in 1896 at the old Triumph Ice Machine Company located in Cincinnati, Ohio.  His first job was as a blue print boy with the duty of developing blue prints from the engineering department, accomplishing this by exposing them to the Sun.  With the experience gained in this department he became an accomplished experienced draftsman and went on in the company to become a salesman, then sales manager and chief engineer.  In 1922 C.P. Wood resigned to form his own company, starting an unbroken series of ammonia refrigeration installations, literally hundreds.  As C.P Wood, Sr.'s two sons David and C.P. Jr. became of age they also joined their father in the ammonia refrigeration business.  At that time it was known as under the C.P. Wood Company.  In the early 80s the C.P. Wood Company was sold.  C.P. Wood, III joined the family business in 1983 and in 1986 partnered with Det Ohst to form a new company.  Det Ohst and C.P. Wood, III then started an ammonia refrigeration business under the name of Frigid Tek, Inc., which was later changed to AARDCO.  C.P. Wood, Jr. is still currently active at AARDCO.  Our record over the last century indicates our devotion to ammonia as the perfect universal refrigerant. Ammonia installations require a special ability that has been ours for years experience.
