2 Lowest energy consumption and total cost of ownership Evaporative cooling for system-wide energy saving at lower operating temperatures. The highly efficient OptiCoil System increases thermal performance up to 30% for the same coil volume lowering the installed fan power by up to 50%. Elimination of potentially excessive operating costs. PFI is Eurovent-CTI certified for both water and glycol. This guarantees thermal performance and it eliminates field thermal performance testing costs. System pump energy savings obtained through shorter coil circuits resulting in lower coil pressure drops. Savings on maintenance and water treatment because the closed loop in PFI cooling towers ensures a contaminant-free cooling circuit. Lower installed costs. PFI has a lower weight, reducing structural and vibration isolation costs. Less glycol is required to achieve the same or higher heat transfer. Water and chemical savings up to 33% because Baltibond Hybrid Coating allows higher cycles of concentration. Year round reliable operation Trouble free process operation - The closed loop in PFI cooling towers protects the process fluid and equipment from external contaminations. The thermal performance of PFI closed circuit cooling towers is tested and certified by Eurovent. For extremely cold weather operation, switch off the spray system during periods of reduced load and operate dry. Optimal thermal performance through lifetime. Lab tests have proven that the OptiCoil System reduces scale formation on the coil. Minimum maintenance and downtime- Complete and easy access to all critical components, including coil. Easy-clean and easy-inspect PFI towers reduce hygiene risks from bacteria (e.g. Legionella) or biofilm inside. Self-cleaning cold water basin sloping towards drain, to prevent sediment build up. Combined inlet shields block sunlight to prevent biological growth in the tower, filter the air and stop water splashing outside. Ideal replacement unit with certified thermal performance Same or higher capacity. Ideal like-for-like solution, performing per published ratings. The PFI is independently Eurovent-CTI certified for various process fluids. Low noise This file has been generated from the BAC website on: For more up to date information, visit:

3 Powered by TCPDF ( A variety of fans is available to offer the perfect solution for every sound challenge. Water silencers achieve noise levels close to those of crossflow towers. Water silencers come always with Whisper Quiet fans. Factory designed, tested and rated sound attenuation is available on the discharge for further noise reduction. Easy to maintain The PFI closed circuit cooling tower is easier to maintain than other induced draft counterflow cooling towers. Optional coil inspection hatches allow complete and easy access to heat transfer section BranchLok water distribution - each branch removable for easy cleaning. Combined inlet shields for easy no-tool removal. Motor adjusters: externally accessible and locking wrench for easy motor alignment and belt tensioning. Full cold water basin access when removing the combined inlet shields. Fans easy accessible via sliding access door. Optional clean out port helps remove silt and sludge from the cooling tower basin. Removable suction strainer anti-vortex hood. Ship and install PFI easily Guide pins mean swift PFI cooling tower on-site assembly. The guide pins help reduce section assembly time by up to 75 %! Compact PFI footprint perfect for confined spaces. Container shipment often possible! Interested in the PFI closed circuit cooling tower for cooling your process fluid?

4 Powered by TCPDF ( PFI Closed circuit cooling towers Principle of operation The PFI features the OptiCoil TM System, which includes the BAC Versapak spray water cooling medium (1). This improves the overall cooling efficiency and ensures an optimal cooling of the warm process fluid (2) inside the coil (3), which is wetted by the spray system (4). The Versapak is inserted within the coil structure, engineered for easy inspection. The axial fan (5) draws ambient air (6) upwards through the tower. Combined inlet shields (7) protect the tower from debris being drawn into the unit. During operation, heat is transferred to the spray water, and then to the atmosphere as a portion of the water that evaporates. The cooled process fluid then exits the unit (8). The sloping sump (9) or basin collects the remaining water. The spray pump (10) recirculates the cooled water to the top of the tower. The warm saturated air leaves the tower through drift eliminators (11) which remove water droplets from the air. Interested in the PFI cooling tower to cool your process fluid?

5 PFI Closed circuit cooling towers Construction details 1. Material options Heavy-gauge hot-dip galvanized steel is used for external unit steel panels and structural elements featuring Baltiplus Corrosion Protection. The unique Baltibond hybrid coating is an optional extra. A hybrid polymer coating for longer service life, applied pre-assembly to all hotdip galvanized steel components of the unit. Optional water contact stainless steel panels and structural elements of type 304 or 316 for extreme applications. Or the economical alternative: a water-contact stainless steel cold water basin. Its key components and the basin itself are stainless steel. The rest is protected with the Baltibond hybrid coating. 2. Heat transfer media Our heat transfer media is a cooling coil. Its thermal performance is proven during comprehensive lab thermal performance tests, and it offers you unrivalled system efficiency. Coil only version optionally available. The coil is constructed of continuous length of prime surface steel, hotdip galvanized after fabrication. Designed for maximum 10 bar operating pressure according to PED. All hot dip galvanized and stainless steel coils are delivered with BAC's Internal Coil Corrosion Protection, to ensure an optimal internal corrosion protection and guaranteed quality. Optional stainless steel coils are in type 304L or 316L. Versapak in self-extinguishing plastic, which will not rot, decay or decompose. For more up to date information, visit:

6 Powered by TCPDF ( 3. Air movement system PFI fan system features two aluminium sheaves and belts. Together with the heavy duty fan shaft bearings and the BAC Impervix motor (external for units up to 2,4 m wide), this guarantees optimal and yearround operational efficiency. Low kw axial fan(s) in corrosion resistant aluminum, encased in fan cylinder with removable fan guard. Easy accessible via sliding access door. To reduce noise even further, choose for a Whisper Quiet fan with minimal impact on thermal performance. Extended lubrication lines with easily accessible grease fittings to lubricate fan shaft bearings. Our drift eliminators come in UV-resistant plastic, which will not rot, decay or decompose and their performance is tested and certified by Eurovent. They are assembled in easily handled and removable sections, for optimal internal access. Easy removable UV-resistant plastic combined inlet shields at air inlet. Sunlight block to prevent biological growth in tower, air filter and water splash-out stop. 4.
