INTRODUCTION

This Cooling Technology Institute (CTI) publication is intended to provide guidelines for winter operation of industrial water cooling towers, and represents the consensus of both manufacturers and users throughout the industry, with a wide range of experience in this field. However, the CTI emphasizes that these are recommendations only and are not necessarily "fail safe".

Although these recommendations are directed towards industrial cooling towers, the principals are valid, for the most part, for HVAC (air conditioning) cooling towers. As an additional consideration, it is recommended that HVAC cooling towers, with an integral cold water basin, be equipped with an immersion type basin heater (ref. CTI TP 75-A).

Proper winter operation of any water cooling tower relies heavily on operator inspection and control. This is essential not only for control of ice formation (to reduce or eliminate costly ice damage), but also to maintain cold (return) water temperature at the proper level, for efficient palnt operation. When falling ambient dry bulb temperatures reach 450F, normal operation procedures should be suspended, and a Winter Operational Plan be put into action, with regular visual inspection of critical tower areas on 2 - 4 hour intervals.
