the cold air supply must be within 5 feet of the person or equipment being cooled, since
the hot ambient air will mix with the cool air very quickly. Your KwiKool system is specifi-
cally designed to adapt to today’s high tech environments such as telecommunication or
computer rooms and is equipped with the necessary controls to maintain those special
environments. Call your nearest KwiKool Distributor or 1-800-594-5665 for help or for
