LoadMatch® System

A LoadMatch® system is the marriage of two old ideas wrapped around a new technology. The old ideas are single pipe distribution and primary-secondary pumping. The new technology consists of the use of maintenance-free wet rotor circulators. The primary distribution system is a single pipe loop; the secondary distribution system is a decoupled secondary piping loop for each terminal unit in the system. The wet rotor circulator provides the specified flow to each terminal unit at all times. The simplicity of the Load-Match® concept allows you to specify one size of pipe for large portions of the system. In single loop installations, there is no limit to the number of coils you can install. Final pipe size is determined by the total load of the loop and ∆T. If your loop is heavily loaded, it’s practical to split the system into two loops with smaller pipe sizes. This change saves installation costs, energy, and money, and can reduce pump head, and lower hp. When loops are carrying equal loads and arranged symmetrically, they will nearly self-balance. The resulting configuration will keep balancing losses down and will lower ongoing energy costs.
