Page 4: General Information
Shipping BAC cooling equipment is factory assembled to assure uniform quality and minimum field assembly. The adiabatic pre-cooler sections of the TrilliumSeries equipment are shipped separately. Refer to below table for number of adiabatic pre-cooler sections per model. -
Page 5: Unit Weights
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. -
Page 6: Freeze Protection
Freeze protection These products must be protected against damage and/or reduced effectiveness due to possible freeze-up by mechanical and operational methods. Please contact your local BAC Balticare representative for recommended protection alternatives. Safety precautions All electrical, mechanical and rotating machinery constitutes a potential hazard, particularly for those not familiar with its design, construction and operation. -
Page 7: Non-Walking Surfaces
BAC will guarantee all products to be free from manufactured defects in materials and workmanship for a period of 24 months from the date of shipment. In the event of any such defect, BAC will repair or provide a replacement. -
Page 8: Rigging
DFCV DFCV-AD RIGGING General notes 1. The equipment arrives on site by truck. It is recommended to unload the unit with a crane. If the adiabatic pre-cooling sections for the TrilliumSeries are crated separately, a forklift should be used for unloading of the crate with adiabatic pre-coolers. A crane must always be used to unload the unit from the truck. -
Page 9: Rigging Method
CAUTION Before an actual lift is undertaken, ensure no water, snow, ice or debris has collected in the unit. Such accumulations will add substantially to the equipment's lifting weight. Rigging method To avoid damage during hoisting, a spreader beam should be used and the angles shown in the diagrams below must be observed. - Page 10 8-fan unit 10-fan unit 12-fan unit W W W .

REMOVAL OF PRE-COOLER MEDIA The pre-cooler media have been placed inside the stainless steel frames for shipment and need to be removed before installation of the empty pre-cooling frames on the dry cooler. Remove the pre-cooler media as follows: Removal of top plate Removal of green water distribution pads W W W .

Place the different pre-cooler frames such that the water distribution piping between sections can be connected, and the copper water piping installed on the unit connects to the water flow meter of the pre-cooling sections.

Side-by-side pre-cooler frames connected with stainless steel connection plates. 5. RE-INSTALLATION OF THE PRE-COOLER MEDIA Re-install the pre-cooler medium (2) and the water distribution pads (1) placed on top of the pre-cooler medium. Re- install the top plate covering the water distribution section.
- Page 16 CAUTION The pre-cooling media have a front side and a back side and need to be (re)installed in the correct position to ensure full wetting over the depth of the media and to ensure maximum efficiency. The blue coloured side needs to be at the outside. Continue with installation of pre-cooler media Re-installation of top plate.
- Page 17 Connection of pre-cooler water inlet to the pre-installed copper water distribution piping. 7. CONNECTION OF DRAINS Connect bottom water drains of all pre-cooler sections at both sides of the unit to evacuate excess water. The surplus of water distributed over the adiabatic pre-cooling media during adiabatic operation is collected into a gutter and drained to the sewer via one or two different drains per pre-cooler side.

Each pre-cooler section has a sloping pan, assuring complete water drainage and discharge of any floating solids to the sewer. Larger debris will however accumulate and settle in the gutter system and may be too large to drain via the bottom drain and finally may block the bottom drain.

Page 21: Inspection Prior To Start-Up
If required, consult your local BAC Balticare representative for assistance. 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. - Page 22 Control panel with Variable Frequency Drive The fan speed is controlled on the basis of the actual process fluid temperature at the exit of the unit and the design leaving temperature, ensuring a minimum in electrical consumption and noise levels. The adiabatic pre-cooling will be activated and stopped on the basis of a pre-programmed logical combination of the fan speed and the ambient temperature (release set-point).
