In June 1988 the Dole Group of Companies was purchased by Climate Master, Inc. of Canada. An air conditioning and heating manufacturer based in Edmonton, Alberta, Climate Master owned all the shares of Dole Refrigerating Company through a wholly owned subsidiary Dole Climate Master, Inc. registered in Delaware.
In February, 1991, John W. Cook, Sr. purchased the Dole Climate Master, Inc. from Cooper & Lybrand after the parent company, Climate Master Ltd. of Alberta, Ontario, Canada was forced into receivership by Royal Bank of Canada.
Under the ownership of Mr. Cook, the company has introduced two new products, the Vertical Plate Freezer and the Side Ram Plate Freezer. Although the competition continues to refer to Dole products as "antiquated," growth has continued as more people recognize the benefits of Dole products.
