It is vitally important to accurately control critical equipment such as chillers, cooling towers and pumps to achieve maximum energy efficiency. The controllability of the chilled water system is only as good as the performance capabilities of the measurement instrumentation and valves you choose. You can rely on the HVAC applications engineering expertise of Spartan Controls to assist with the proper sizing and selection of valves and instruments to ensure safe, reliable and energy efficient performance.
We offer the full portfolio of Emerson control and isolation valves, valve actuators and measurement instrumentation including:
The min/max flow rates through the chilled water system can vary widely as outdoor temperatures swing from season to season. The high turndown ratio and precision control capability of Emerson's Fisher Vee-Ball rotary modulating valves are ideally suited to handle these wide swings in operating conditions to ensure optimal energy efficiency and performance. Typical chilled water system applications include:
Scale, corrosion, airborne debris, and suspended solids is the cause of many valve failures in condenser water in both open and closed cooling towers. Most high performance butterfly valves have pressure assisted seat designs that allows debris to build up behind the seat preventing the disc from fully closing. This causes seat leakage and premature valve failures. Emerson's Keystone K-LOK high performance butterfly valve with its true interference fit seat design, does not rely on line pressure to seal tightly. Plus unlike most other designs, there are no voids behind the K-LOK seat where debris can collect, making it ideally suited for dirty services.Precision cooling tower level measurement prevent overfills.
The use of Rosemount 3300 precision guided wave level transmitters in cooling tower applications provides superior level measurement to prevent overfill scenarios. It has no moving parts, needs no calibration, and is virtually unaffected by process conditions. With top down level and interface measurements you are in total control of your level applications.
Being one the largest consumers of energy in a building, the chilled water system can have a significant impact on operational costs and carbon emissions. In addition to energy usage, critical chiller machinery failures can adversely impact maintenance costs and downtime.
Ongoing routine maintenance represents the minimum starting point. Implementing predictive maintenance and energy optimization strategies requires real-time operational data. Innovative IIIoT technologies and software lhave opened the door to new ways of improving and sustaining energy and performance efficiencies of critical machinery through its online 24/7 condition and performance monitoring capabilities.
SpartanPRO™ EMIS is a software platform that consolidates and analyzes energy data in real time in a user-friendly format for stakeholders ranging from operating crews to corporate executives. By capturing and contextualizing energy consumption data, SpartanPRO™ EMIS will provide insight into current energy performance, highlight abnormal events, and help track down high energy users in order to ensure that site is consistently operating at peak energy efficiency with minimal emissions.
