St. Elizabeth Healthcare operates five facilities throughout Northern Kentucky, including St. Elizabeth Healthcare Edgewood, a state-of-the-art general medical and surgical facility.
As a healthcare facility serving the larger Cincinnati metro area, there is a constant flow of patients, visitors, and medical personnel through their halls. Unfortunately, the hot water was not flowing quite so quickly. For years the hospital had dealt with an unreliable and unbalanced hot water supply. The domestic hot water system’s (DHWS) return runs were operating inefficiently, leaving some of the hospital wings completely without hot water at times.
To address this problem, MarkCo Plumbing installed around 90 CircuitSolver® balancing valves in their DHWS. The CircuitSolvers® were installed at the end of each hot water branch in the system, replacing the manual balancing valves. These self-actuating, thermostatic recirculation valves automatically and continuously adjusted the flow to maintain the specified temperature at the end of each domestic hot water supply line. No manual balancing was required.
After the successful CircuitSolver® installation, St. Elizabeth Healthcare Edgewood now has access to an on demand hot water supply in all wings, on every floor, at every fixture. CircuitSolver® was able to balance the system when engineers could not.
Where manual balancing fails, CircuitSolver® delivers.
The CircuitSolver® is a thermostatic, self-actuating balancing valve that continuously and automatically adjusts the flow through each branch of a domestic hot water recirculation system to maintain the specified temperature at the end of each branch, regardless of fluctuations in hot water demand. It is a direct replacement for manual balancing valves and eliminates balancing labor and callbacks.
ThermOmegaTech’s STVM Washdown Station utilizes a silent type venture mixing valve to combine steam and water together to produce a user defined temperature. This ingeniously designed product is efficient, easy to maintain, and most importantly safe – a necessary addition to any facility that uses washdown stations.
Designed to have a quick startup time and an even shorter downtime, the STVM features an interchangeable cartridge for ease of maintenance. Unlike other manufacturer’s washdown stations that require a specialized tool and the user to take the unit off the wall to perform regular maintenance, ThermOmegaTech’s STVM Washdown Station requires only a standard wrench and doesn’t need to be moved from its point of installation. Simply unscrew the cartridge from the top of the unit, put in a new cartridge, and the unit is up and running within moments.
As the STVM unit uses steam to heat water, personnel safety is a top priority. If the cold-water supply to the unit is interrupted the thermostatic mixing valve will sense the over-temperature flow and close off, preventing operation. The valve will remain closed until the cold water supply is restored, after which it will automatically open and re-establish flow, protecting both personnel and equipment.
FAQs about the STVM Washdown Station:
Q: What is the difference between a 150°F unit and a 185°F unit? A: These numbers indicate the unit’s over-temperature shutoff point, typically due to a sudden lack of a cold-water supply. Once the unit’s thermostatic actuator senses its set shut-off temperature (either 150°F or 185°F, depending on the model) the internal mixing valve will modulate closed and stop the flow. Only after the cold-water supply has been restored to the unit will the valve modulate open and re-establish flow. The unit’s over-temperature shutoff point is not field adjustable.
Q: How can we make the unit’s downtime for maintenance even shorter? A: Keep a spare cartridge on hand! Don’t wait for the STVM® Washdown Station to require maintenance to order a new cartridge as the lead time will result in the unit being out of service until the new cartridge is received. By keeping a spare cartridge on hand the station’s downtime is minimized, allowing personnel to get back to work sooner.
