1900 VFD Series Close-Coupled In-Line Pumps

The 1900 VFD Series Close-Coupled In-Line Pumps meet the latest industry standards for hydraulic performance and reliability. The 1900 VFD Series Close-Coupled In-Line Pumps are compact, energy efficient and can be installed anywhere in the piping layout.

Let the variable frequency drive (VFD) on the 1900 VFD Series Close-Coupled In-Line Pump operate your buildings with greater efficiency; using them to control your pumps can significantly reduce energy costs. Most HVAC systems are designed to keep the building cool on the hottest days and warm on the coldest days. Therefore, the HVAC system only needs to work at full capacity on the 10 or so hottest days and the 10 or so coldest days of the year. On the other 345 days, the HVAC system may operate at a reduced capacity. This is where a system with variable frequency drives (VFDs) can be used to match system flow to actual heating and cooling demands. The VFD can reduce the motor speed when full flow is not required, thereby reducing the power required and the electrical energy used.

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.
