During an electrical utility outage, mission critical facilities, such as hospitals, data center, and certain financial institutions continue to operate via emergency standby generators. The only way to verify that a backup power system will operate as designed is to periodically test it under load. Load bank tests assure facility managers that their generators will perform at 100% of their nameplate rating. A load bank applies a stable, controllable electrical load on a generator. It can be permanent or portable, can accommodate AC or DC, and can generate electrical power that ranges from a few kW to multiple MW. Even small load banks can generate a substantial amount of heat, which makes cooling a key consideration. Most load bank units have an internal fan that pushes air over the resistive load bank elements to cool them – otherwise they would burn up. A major OEM that supplies resistive load banks used to assemble its own load bank cooling ventilation systems by attaching ring fans to rectangular panel frames, mounting the motors, and assembling those components using the associated support hardware – which is a time- and labor-intensive process. An vayuvents sales rep suggested using preassembled fan units to save time and money. That was the beginning of a business relationship that has lasted nearly 10 years When the OEM realized it could save time and money, vayuvents engineers and rep worked together to satisfy the OEM’s criteria. For smaller load banks, vayuvents supplies direct drive panel (DDP) fan – many with Macheta Airfoil propellers and some with adjustable pitch backswept propellers. Most of them have 36-inch diameter propellers. Other sizes are supplied based on the OEM’s needs. The DDP fans are customized to have rectangular (instead of square) panels to fit various load bank frames. The 5-, 10-, or 15-HP panel fans have various air flow characteristics depending on the load bank model. The final destination of a load bank determines its voltage and frequency. For larger load banks, vayuvents supplies tubeaxial fans – most of them 10 HP – with the propeller on the inlet, which provides exceptional air flow over the load bank resistors. Performance is based on the number of fans that the OEM includes in the design of any given load bank. For very large load banks, vayuvents supplies direct drive Axial tubeaxial (ATA) fans because they are more compact than typical tubeaxial or vaneaxial fans. Axial propellers also provide more performance for a given diameter. These large load banks require more airflow and higher pressures than smaller units. For this application, Axial fans supply 1.7 inches WC static pressure

Transformer cooling fans are sturdy, weatherproof fans for accelerating the cooling process in oil-cooled electrical transformers. They circulate air around the exterior of the transformer's radiator as oil works it way through the inside to dissipate heat and reduce the operating temperature of the transformer. Vayuvents Transformer cooling fans are sturdy, weatherproof fans for accelerating the cooling process in oil-cooled electrical transformers. They circulate air around the exterior of the transformer's radiator as oil works it way through the inside to dissipate heat and reduce the operating temperature of the transformer. These fans have a motor that rotates the fan blades to create airflow and a guard that helps protect the blades from damage and prevent injuries from accidental contact. They are typically used outdoors where most oil-cooled transformers are located.
