We are in the process of setting up a new facility and are looking to procure air handling units (AHUs) and ventilation systems that meet our specific requirements. We're interested in understanding the types of units you can provide, including details on their specifications, energy efficiency ratings, and any customization options that might be available. Additionally, please share information regarding lead times for delivery and your pricing structure, including any bulk purchase discounts. Understanding your warranty and service support options would also be beneficial. We're looking to move quickly, so a prompt response would be greatly appreciated as we finalize our selections. Thank you!
