This Velocity Boiler Works Heat Exchanger is a crucial component designed for efficient heat transfer from one medium to another. It is specifically engineered for 150/180 models, ensuring compatibility and seamless integration. The heat exchanger operates by allowing hot boiler water to flow on one side, while simultaneously running tap water in the opposite direction. This counter-current flow results in higher efficiency and a faster heating rate compared to other types of heat exchangers. Constructed from durable materials, it is designed to withstand high temperatures and pressures, providing reliable performance over time. The product adheres to industry standards, ensuring safety and quality in its operation.
