Ronald ViskilBoard Member
Ronald Viskil is the founder of Unicorn B.V. When Unicorn started with the sales and servicing of recovery and recycling machines for the collection and reuse of refrigerants in 1991, expertise in this field was still very limited. Over 25 years later, Unicorn can justifiably claim to be a ‘specialist in refrigeration, recovery, recycling and reclaiming technology’. For refrigeration installations of all sizes and any kind of ‘mobile refrigeration system’, whether it drives, sails, flies or is stuck to concrete.
