4 - B 80 Benefits Different Construction Material Options To meat each customers technical and economic requirement, cooling towers offer a broad choice of construction materials such as : Fibreglass Reinforced Polyester cladding with a hot dip galvanised steel structure Z600 hot dip galvanised cladding and structure protected with the unique Baltibond Corrosion Protection System. Fibreglass Reinforced Polyester cladding with a stainless steel structure Choice of Heat Transfer Surface Alternatives In addition to the standard heat transfer surface, wide spaced film type and heavy duty cleanable fill material is available. Total Lower Installed Cost Modular Design - The time consuming field assembly of individual parts is reduced to the rigging of large factory assembled sections and final assembly details. Your own construction people can receive the shipment, assemble the modules and component parts, and complete the cooling tower installation in a fraction of time required for conventional field erected cooling towers. Less construction time on site means less susceptibility to the variables of weather, labour productivity and workmanship. Field cutting, patching and drilling are virtually eliminated by use of standardized modular sections. The result is the consistent high quality, quickly assembled installation required by today s industrial cooling tower user.

7 - B 83 Custom Features and Options Construction Options Standard Construction: Structural elements are constructed of Z600 heavy-gauge galvanized steel, hot-dip galvanized after fabrication. Optional BALTIBOND Corrosion Protection System: The BALTIBOND Corrosion Protection System, a hybrid polymer coating used to extend equipment life, is applied to all hot-dip galvanized steel components of the unit. Optional Stainless Steel Construction: Structural elements are constructed of stainless steel either type 304 or 316. Note: Refer to section Technical Resources, Material Options for more details on the materials described above. * Optional on models 500 to 990.

One drive assembly is sized for full speed and load, and the other is sized for approximately 2/3 speed and consumes only 1/3 of the design kilowatt power. This configuration allows the system to be operated like a two-speed motor, but with the reserve capacity of a standby motor in the event of failure. As a minimum, approximately 70% capacity will be available from the low kilowatt motor, even on a design wet-bulb day. Controls and wiring are the same, as those Baltiguard Drive System required for a two-speed, two-winding motor. Significant energy savings are achieved when operating at low speed during periods of reduced load and/or low wet-bulb temperatures.... because temperature matters

- B 84 Wetdeck Surface Standard Heat Transfer Surface: The filmtype heat transfer surface supplied as standard with the cooling towers has been carefully selected for industrial applications.

8 - B 84 Wetdeck Surface Standard Heat Transfer Surface: The filmtype heat transfer surface supplied as standard with the cooling towers has been carefully selected for industrial applications. The 19 mm spacing between the surface sheets gives excellent air/water contact with low air pressure loss. The standard heat transfer surface provides high thermal efficiency and is sufficient to avoid clogging in most environments. Optional Film-Type Space 12 mm: For applications where the cooling tower water is clean, alternative models with 12 mm fill are available. Telescopic fill supports (only for heavy duty 26 mm Fill Type) Heavy Duty 26 mm Fill Type: Heavier contamination, which results in a heavy accumulation on the heat transfer surface, requires a higher structural strength than can be accomplished with film-type. For such situations, a heat transfer surface is available, constructed of heavy-duty wave formed FRP panels spaced 26 mm apart. With the unique integrated telescopic fill supports, the FRP fill panels can easily be removed for cleaning. Cold Water Basin Integral cold water basins are available as an option on models 500 to 990 and models to Model No. Sump Height Sump Weight (kg) Sump Volume (l) Make Up Size ND Water Outlet Size ND Equalizer Size ND (2x) 250 (2x) (2x) 250 (2x) (2x) 250 (2x) (2x) 250 (2x) (1x) 300 (2x) (1x) 300 (2x) 250 Low Sound Fan To maintain the quality of the local environment, the cooling tower can be furnished with a low sound fan. Baltimore Aircoil

9 - B 85 Accessories Electric Water Level Control Package The electric water level control to allow replaces the standard mechanical make-up valve when a more precise water level control is required. This package consists of a float switch mounted in the basin and a solenoid activated valve in the make-up water line. The valve is slow closing to minimize water hammer. (Only for models 500 up to 990 with factory supplied basin.) Vibration Cutout Switch A factory-mounted vibration cut-out switch is available to effectively protect against equipment failure due to excessive vibration of the mechanical equipment system. BAC can provide a vibration cut-out switch in an IP65 enclosure to ensure reliable protection. Two-Speed Fan Motor An effective method of adding steps of capacity control and saving energy is the installation of twospeed fan motors in lieu of the standard single-speed motors. Two-speed motors are ideally suited for this purpose. At half fan speed the equipment capacity is still about 60% of design whereas the drawn fan power is only about 20% of the full speed motor power. In addition, at low speed, sound levels will generally reduce by about 9 db(a). Basin Heaters Units exposed to below freezing ambient temperatures require protection to prevent freezing of the water in the cold water basin when the unit is idle. Factory-installed heaters, which maintain the water temperature at 4 C, are a simple and inexpensive way of providing such protection. The heater package includes the heaters, a thermostat and a low level cut out switch to protect the heaters if the water level is too low. Standard electric heaters are selected for -18 C ambient temperature. (Only for models 500 up to 990 with factory supplied basin). Model No. Heaters -18 C (kw) x x x 6 Two-Step Thermostat Single stage thermostats or two stage thermostats can be used for fan motor speed control. Maintenance Switch Safety switches or local isolators allow the electrical supply to motors to be disconnected for safety purposes during inspection or maintenance.
