Start Counting Your Savings RULE #1. Choose the least expensive heat rejection technology RULE #2. Use hybrid systems to save energy RULE #3. Get some expert advice. Make it pay to go green! Air cooled heat exchanger Chiller (mechanical refrigeration) Evaporative cooling tower with outdoor mechanical room ���� � ���� ���������� ������� � ��� � ���������� ��� � � ��� ������������� � ���������������� ��������� ���� ����������� ������������� Combine different types of systems to achieve the best features of each with the greatest energy savings. The "free cooler" shown at right eliminates the need for refrigeration compressors to run in a cold winter climate, saving energy and wear and tear on the chiller. Another hybrid example is to "trim cool" an air cooled heat exchanger with an evaporative tower used in summer only. Substantial savings are realized in water, chemicals and electricity. TYPE OPERATING COST TEMPERATURE Air Cooled $ 105°F Evaporative $$ 85°F Chiller $$$$ 65°F When choosing a cooling system consider your climate and the maximum operating temperature of your equipment for optimum efficiency. Lower fluid temperatures increase energy usage and operating costs. 3 0 years serving the Heat Treating Industry. call 800-525-8173 Fax: 248-969-3401 575 S.
