Cooling towers are heat rejection devices used in HVAC and industrial systems to remove excess heat from water. They work on the principle of evaporative cooling, where warm water is distributed over fill media while air flows through the tower. As a small portion of water evaporates, heat is released, cooling the remaining water before it is recirculated back into the system.

Variable Refrigerant Flow (VRF) systems are advanced HVAC solutions that regulate refrigerant flow to multiple indoor units based on real-time demand. Using inverter-driven compressors, VRF systems provide precise temperature control, high energy efficiency, and flexible zoning, making them ideal for modern commercial and residential buildings.
