The Institute of Refrigeration announces this month ten members who are being recognised as Fellows of the Institute in recognition of their leadership, volunteer work and contribution to improving the standing of the RACHP industry. Their short biographies below demonstrate the range of interests IOR members have and how they are helping the IOR to encourage the next generation of engineers and technicians, advancing technology or raising the profile of our industry. This also reflects the priority action areas for the IOR for 2023 which focus on education, sustainability, heat pump and skills. IOR Fellows are long-term members of the IOR with a commitment to leading and advancing our industry that goes beyond their day-to-day work responsibilities.
