/ Introduction /

The purpose of a basin heater is to prevent water freezing in the cooling tower basin during periods of shutdown or standby operation. The heater system is sized according to tower model and location to give maximum protection against water freezing in the cold water basin. This heating

system is not intended to protect the tower fill and other components from icing. Refer to Marley Technical Bulletin # H-002"Operating Cooling Towers in Freezing Weather." Contact your Marley Sales Representative

for a copy of this publication.

The Marley basin heater system is manufactured by INDEECO, a leader in immersion heating equipment. The system is referred to as a "heater package" and consists of immersion heaters, a control panel and combina- tion temperature / liquid level sensor with a 12'-0" cable length. The basic control panel contains a contactor(s) of sufficient capacity for the heater elements selected. In addition the panel contains a transformer to reduce line voltage to 24VAC for panel control power, and a solid state relay card to detect low temperature and low water conditions. The panel enclosure is rated NEMA 4X (liquid tight, noncorrosive) and the sensor cable is UL outdoor rated. The sensor probe is stainless steel with 1⁄2" NPT threads and a PVC bulkhead fitting for installation in the cold water basin.

The panel may control more than one heating element, up to its nameplate KW rating for the voltage and phase stated. In addition to the components of the basic panel described above, available options are fusing, circuit breakers or disconnect switches. The circuit diagram located on the inside of the panel cover will indicate the panel configuration.
