GENERAL INFORMATION
Operating Conditions
BAC cooling equipment is designed for the operating conditions specified below, which must not be exceeded
during operation.
•
Wind Load : For safe operation of unshielded equipment exposed to wind speeds above 120 km/h installed at a
height above 30 m from the ground, contact your local BAC-Balticare representative.
• Seismic Risk : For safe operation of equipment installed in moderate and high hazard area's contact your local
BAC-Balticare representative.
Standard electrical motors are suitable for an ambient temperature range from -25°C to +40°C.
With proper maintenance, the estimated life expectancy for the coils is 15 years.
• Design pressure: max. 10 bar
• Fluid inlet temperature: max. 82°C
• Fluid outlet temperature: min. 10°C
Fluids circulated through the inside of the coils must be compatible with the coil construction material, ie.
- black steel, for hot dip galvanized coils
- stainless steel AISI 304L or 316L (options)
- galvanized steel for cleanable coil (option)
Maximum spray pressure: 14 kPa (If pump(s) are installed by others, it is recommended to install a pressure gauge
at the inlet of the water distribution system.)
Stand-by pump arrangements for evaporative fluid coolers require alternating operation of each pump at
least twice per week to avoid stagnant water conditions and bacteriological growth.
PURGE REQUIREMENTS
The installer of BAC closed circuit cooling towers must ensure a proper air purging of the system prior to operation.
Entrained air can restrict the capacity of the cooler, resulting in higher process temperatures.
All connections (installed by others) must be leak free and tested accordingly.
CIRCULATING WATER QUALITY
The standard heat exchanger coils are made of black steel and are galvanized on the outside only. They are
intended for application on closed, pressurized systems which are not open to the atmosphere in order to prevent
internal corrosion of the coil and possible leaks.
The circulating water quality needs to remain within the following limits:
pH 7 - 10.5
Hardness (as CaCO3) 100 - 500 mg/l
Alkalinity (as CaCO3) 100 - 500 mg/l
