Installation Site Overview

iusmg 300x167 - CircuitSolver Install: Mental Health Institute of Quebec
Aerial View of IUSMQ

The Mental Health Institute of Quebec (IUSMQ) is a hospital specializing in psychiatric care. Founded in Quebec City in 2009, the facility has more than 500 beds for short-term and long-term psychiatric care.

IUSMQ is a large building with up to 6 floors in some wings and a total floor area of about 160,000 m². To accommodate changing staff and patient needs, the IUSMQ’s main pavilion was recently renovated, with updates being made to the domestic hot water recirculation system.

The Opportunity

Instead of implementing an army of traditional hot water heaters to supply the sprawling facility, IUSMQ’s water supply is heated by a hospital-owned power plant and distributed throughout its wings and floors.

To account for the heat loss that occurred as the hot water traveled through the building’s long recirculation lines, the power plant had to intentionally “overheat” the water being delivered to IUSMQ.

However, as a result of new standards and regulations, the hospital was required to adjust the temperature of incoming water to a safer level.

According to the building’s consultant, André Renaud, this resulted in the hospital experiencing a lack of hot water in some areas.

The Installation

Renaud initially reviewed the recirculation system to determine the fixed flow rate needed to offset heat loss and consumption. According to his calculations, the main recirculation piping would not be able to withstand the high flow rate required due to the risk of premature erosion of the copper piping.

Due to this, the consultant chose to replace the system’s fixed flow valves with 108 CircuitSolvers. sizes 300x131 - CircuitSolver Install: Mental Health Institute of Quebec
Installed in-line, CircuitSolver is a self-actuating, thermostatic recirculation valve that automatically and continuously adjusts flow to maintain a specified temperature at the end of each domestic hot water supply line.

CircuitSolver bases dynamic flow rates solely on fluid temperature, easily accommodating for passive system heat loss and demand fluctuations, with no need for re-balancing.

By switching to the CircuitSolver, Renaud eliminated the labor and guesswork associated with the manual balancing of fixed flow valves.

The Result

After a quick and easy install and almost instantaneous automatic balancing, hot water is now available throughout the entire main pavilion on demand.

Code Compliant DTV – Simplify By Plumbing For Compliance

Code Compliant DTV – Simplify By Plumbing For Compliance

As a component of their normal operation, commercial equipment such as dishwashers, combi ovens, and steam humidifiers discharge superheated steam and water. This effluent needs to be tempered down before going to drain and entering public sewers.

ThermOmegaTech® offers the drain tempering valve (DTV) to simplify this process and comply with drain temperature limitations of international plumbing codes.

See some FAQs about the DTV below.


bd33d443 ac22 4ea3 ae49 9694fdbd4e07 1024x410 - Code Compliant DTV - Simplify By Plumbing For Compliance

FAQ #1: When should the DTV be used?

A DTV should be used in any application where drain effluent with temperatures exceeding 140°F must be cooled prior to entering a public sewer in accordance with plumbing codes.

Failure to comply with these temperature limitations may lead to failed inspections, fines, and damage to PVC piping or equipment.

FAQ #2: How does the DTV work?

The DTV is installed into the drain line so that the hot effluent passes over the thermostatic actuator to constantly monitor drain water temperature. When effluent temperatures rise above the valve’s set-point, the valve will automatically modulate open to allow cold water to flow into the drain, cooling the effluent.

Once the effluent’s temperature falls below the set-point, the DTV modulates closed, cutting off cold water flow to conserve water.

FAQ #3: Can the DTV handle steam?

Yes, the DTV can handle fluid temperatures up to 250°F.

FAQ #4: What sizes are available?

The DTV is offered in 1/2″, 3/4″, and 1″ sizes in both brass and stainless steel.

FAQ #5: How do I select a size?

Reliable and self-operating, the DTV ensures drain water temperatures comply with internationally mandated plumbing regulations.

CircuitSolver Competition: How Other Balancing Valves Measure Up

CircuitSolver Competition: How Other Balancing Valves Measure Up

Design engineers have a few options to choose from when selecting a balancing valve to include in a domestic hot water system. The differences between the valves are not always readily available, and the amount of information on the internet can be overwhelming to distill down on calls with engineers or contractors.

Thermal Disinfection Options

High-temperature sanitary flushes are performed in domestic hot water recirculation systems to kill Legionella bacteria and prevent growth.

The CircuitSolver® Sanitary Flush Valve features a dual-actuator to automatically balance the DHWS, even during the disinfection process. A “low-temp” actuator balances the system during normal operation, and a second “high-temp” actuator allows for maximum flow during the high-temperature flush.

Guaranteed Drain Effluent Compliance with the DTV

Guaranteed Drain Effluent Compliance with the DTV

Temperature is often a subjective experience – how cold is jacket weather, how hot is too hot for a shower, etc.

What is never subjective? Drain effluent temperature restrictions.

Drain water from commercial equipment exceeding the 140°F cut-off point can significantly impact a business’ operations due to failed inspections, fines, and damaged PVC piping.

To simplify compliance with international plumbing codes governing effluent flow, ThermOmegaTech offers the drain tempering valve (DTV). Compact and effective, the DTV is 100% self-operating and is incredibly easy to install on new or pre-existing commercial equipment set-ups.

DTVs2 1024x410 - Guaranteed Drain Effluent Compliance with the DTV

The DTV is installed into the equipment’s drain line so the hot effluent flows over the valve’s thermal actuator, with a cold water supply on the valve’s inlet. While there, the DTV continuously monitors effluent temperatures.

When the effluent’s temperature reaches the DTV’s set-point, the valve will automatically open to mix in cold water and temper down the effluent into compliance range.

Once the effluent temperature has fallen to the DTV’s set-point, the valve will shut off the cold flow to conserve water.

 

Selecting a DTV

The DTV is offered in several sizes with differing flow rates. To streamline selecting the size best suited to your individual tempering application, use our online DTV Flow Calculator tool.

Don’t sweat the next inspector’s visit – choose the drain tempering valve for guaranteed effluent compliance with all international plumbing codes.
