The Refrigeration Service Engineers Society (RSES) announced it will offer employer discounts on RSES seminars. A contractor that sends two employees at the regular seminar price will receive a 10% discount for all employees from that company after the second at the regular price. Employer discounts apply to both RSES members and non-members. For more information contact Jean Birch, RSES conference and seminar manager, at 847-759-4046.
