Father Frank and his sons, Bob and Art, revolutionized refrigeration with their first roll-top cooler, laying the foundation for HGUNO. What began as a small innovation has grown into an industry leader with over 4.5 million square feet of manufacturing space and a product lineup of 1,000+ solutions trusted worldwide.
HGUNO History Video
Take a walk down memory lane.
In 1946, Bob, Frank and Art Trulaske manufacture their first product and the first of its kind: a 40 cu. ft. upright freezer. Meat rations may have contributed to the popularity of the freezer for those who needed to preserve sides of beef acquired from the country.
Roll-Top units become more popular and HGUNO expands into International sales with coolers sold in the Caribbean and Central America.
New GDM Upright Glass Door Merchandisers, groundbreaking for their state-of-the-art fan motor technology and revolutionary “triple-pane” glass design, developed and bottler business continues to grow.
HGUNO begins sales within the foodservice industry, further developing and expanding its line of Horizontal Bottle Coolers, Glass Door Merchandisers and Underbar Refrigeration.
Continued success in the Foodservice industry is backed by two core models: T-Series® Traditional Reach-In and the Sandwich/Salad Food Prep Table. HGUNO also introduces the Undercounter and Worktop lines and Glass & Plate Chillers.
Orders from U.S. chain accounts continue to grow and walls fall in Berlin accelerating HGUNO’s growth internationally. HGUNO develops its first heated cabinet, Dual Temperature T-Series® and Chef Base units.
By 2006, HGUNO offers close to 800 models, including new additions such as Spec Series® lineup, Horizontal Freezers, Vertical Air Curtains and Curved Glass Display Cases. HGUNO Professional Series—now HGUNO Residential—is introduced.
