Proven Applications in Healthcare Facilities
Griswold Controls valves have been installed in thousands of hospitals and healthcare facilities across the country. With our substantial experience, we know that Hospital HVAC Systems work harder than HVAC systems in most buildings because they run 24/7/365. Furthermore, they contribute to the health of the patients in the room by improving air quality and mitigating airborne disease transmission. Most hospitals have year-round cooling requirements due to medical devices or systems that generate tremendous amounts of heat such as imaging systems, bright lighting, and refrigeration. Unlike most HVAC systems where comfort is the primary objective for design, engineers designing hospital HVAC systems have additional details to consider that impact health and safety. Therefore it’s critical that these systems operate with consistent high performance in the most cost-efficient method possible.
Reduce Energy and Maintain Comfort in Healthcare Facilities
For over 55 years, Griswold Controls has improved the efficiency of hydronic HVAC equipment in hospitals by controlling the flow rate of hot or cold water to the coils. Griswold Controls designed the first balance valve on the market. Our automatic flow limiting cartridge controls the flow regardless of pressure changes in the system. This guarantees the coil performs at the engineer’s design Delta T at all times. In the early 2000s, Griswold Controls was the first manufacturer to market pressure independent valves to hospitals for operating rooms. Controlling the climate in an operating room is a precise job. A pressure independent valve controls the flow at all times, even in reduced load conditions. Griswold Controls’ latest product line, the EPIC System, directly controls the Delta T of the coil, reducing energy from over-pumping while maintaining occupant comfort.
Guaranteed Heating and Cooling When Healthcare Facilities Need It Most
Automatic flow limiting valves, pressure independent valves, and the EPIC System are all automatic valves. They don’t require any balancing at the job site, so the flowrate or Delta T at the coil meets the engineer’s design specifications the moment the system is started up. They continue to provide design flow or design Delta T even as the building is occupied and the loads change. By removing the need to balance and protecting the coils from changing flows due to system pressure changes, we guarantee the correct heating or cooling at all times. This means one less
thing for the design engineer to worry about. This makes the Griswold Controls valves the perfect prescription for a healthy HVAC System.

Description
Is there a more popular saying than “What happens in Vegas, stays in Vegas?” For those who have been to Las Vegas, they know how popular it is. The people at West Henderson Hospital are trying to make sure that you leave Vegas in good enough shape to keep the tales a secret.
At $9,625,000 per acre, this new hospital is set to leave hardly any medical need unmet. A 37-bay emergency department, heart and hybrid suites, and interventional radiology will all be supported by imaging, pharmacy, and laboratory departments.
All of these expertly assembled and staffed medical suites need precision in every part of their environment. Hospital HVAC systems work harder than HVAC systems in most buildings because they run 24/7/365. Furthermore, they contribute to the health of patients in the room by improving air quality and mitigating airborne disease transmission.

City of Hope Cancer Center – Irvine
City of Hope Cancer Center – Irvine
Patient-focused, LEED-certified cancer care and research hub in Orange County.
Facility Description
The City of Hope Cancer Center will be a 190,000 square-foot, LEED-certified cancer center of the future in Irvine, California, and one of our personal favorite projects since it is a few miles from our factory. It is to be located on 11 acres of the master-planned FivePoint Gateway community. The center will become a regional cancer care hub in the heart of Irvine for years to come.
This patient-focused location offers highly specialized cancer care, clinical research with access to Phase 1-3 clinical trials, precision medicine, and early detection and prevention programs. It will be the home of leading cancer researchers and care professionals and be a center for innovation and compassionate care.
Every step of the way, they have been working with patients, caregivers, and the community. In fact, they began planning for the building by inviting hundreds of people to a design session. They asked participants to walk through mock-ups and provide feedback on everything from patient rooms to corridors to meeting areas. The result will be a facility that is tailor-made to Orange County.
Project Description
However, not only the design work is tailor-made. The HVAC is as well and it needs to be for such an important building. This project is using brass and steel flanged QuickSet valves along with some complimentary equipment in the form of Isolator S and Flanged strainers. For those that don’t know a lot about QuickSet, here is why our clients choose it.
When a Contractor’s Manual Balance Valve readings are anything less than ±1% accurate, the engineer’s system design is costing someone money. In many installations, contractors may sacrifice accuracy for space considerations since traditional Manual Balance Valves require straight pipe length upstream and downstream. Straight pipe length is not required with Griswold’s Disturbed Flow Measurement used exclusively in the QuickSet Manual Balance Valves. When the engineer specifies a QuickSet, they can count on the balancing contractor getting a ±1% test accuracy no matter what space the contractor has to install the valve. The engineer’s QuickSet specification guarantees the energy efficiency and lower operating cost desired by the owner (Read more here).
We are so excited to be working with the City of Hope and we can't wait to see the City of Hope Cancer Center help an immeasurable amount of lives!
