Case Studies
Case Study 1: Revolutionizing Cooling Systems: Custom Thermal Actuators for ABB
Challenge:
Offshore oil rigs operate in some of the harshest environments on Earth. Salt spray, extreme temperatures, and constant exposure to the elements can cause valves to fail at an alarming rate. These failures can lead to costly production downtime and even safety hazards. ABB, a global leader in technology, was seeking a valve solution to control cooling air for sensitive electronic equipment installed on offshore oil rigs. The valve needed to withstand the corrosive environment while ensuring efficient cooling operations.
Solution:
Keystone collaborated with ABB to design a specialized valve tailored to meet the demanding requirements of offshore applications. Utilizing our expertise and engineering, we developed a valve composed of 316 stainless steel. This austenitic chromium-nickel stainless steel alloy is renowned for its exceptional corrosion resistance, mechanical properties, and versatility across a multitude of applications. The valve design not only ensured superior corrosion resistance but also provided reliable performance in the challenging marine environment.
Outcome:
The customized valve solution provided by Keystone met and exceeded ABB’s expectations. By implementing our corrosion-resistant valve, ABB achieved optimal cooling control for their sensitive electronic equipment aboard offshore oil rigs. The durability and reliability of the valve contributed to uninterrupted operations, enhancing the efficiency and longevity of ABB’s offshore assets.
Case Study 2: Streamlining Heat Exchange—Thermal and Pressure Relief Solutions for API
Challenge:
API, a leading provider of industrial equipment, needed to improve their existing product line of very popular heat exchangers. Although they had successfully incorporated a pressure relief valve and bypass into the heat exchangers, they wanted more. Knowing that if they could bypass the heat exchanger when it was not needed, they could improve overall system performance and efficiency.
They benefited was from improved performance and efficiency, while maintaining the safety provided by the pressure relief valve.
Solution:
Keystone engineered a combination thermal and pressure relief valve tailored to API’s specific requirements. The valve was designed to regulate flow into the heat exchanger and bypass flow around it as needed. Additionally, the valve incorporated a pressure relief mechanism to divert flow away from the heat exchanger in case of high pressure within the system. This integrated solution provided precise control of fluid flow while ensuring safety and reliability in operation.
Outcome:
The customized valve solution provided by Keystone enabled API to optimize the performance of their heat exchanger system. By efficiently controlling flow and relieving pressure as necessary, the valve enhanced the overall functionality and safety of their heat exchangers.
Case Study 3: Enhancing Performance—Vacutech's Advanced Cooling Solutions
Challenge:
Vacutech, a leading manufacturer of car wash vacuum systems, faced issues with overheating vacuum pumps during operation. They sought a solution to introduce cool fresh air into the system when heat levels rose, improving performance and extending the lifespan of their equipment.
Solution:
Keystone collaborated with Vacutech to implement a tailored solution utilizing our thermal actuator technology. We designed a damper controlled by a Keystone thermal actuator to regulate airflow within the vacuum system. The thermal actuator responded to changes in temperature, automatically adjusting the damper to introduce cool fresh air when needed, effectively mitigating overheating issues.
Outcome:
By incorporating Keystone’s thermal actuator-controlled damper into their vacuum systems, Vacutech experienced significant improvements in performance and reliability. The automated airflow regulation provided by the thermal actuator enhanced cooling efficiency, preventing overheating and prolonging the lifespan of vacuum pumps. Vacutech achieved greater operational stability and reduced maintenance costs, ensuring consistent performance of their car wash vacuum systems.
Case Study 4: Safe Rinse Water Solutions—Sapphire Scientific's Temperature Control
Challenge:
In the world of dentistry, even minor inconveniences can disrupt patient care. One common concern dentists face is ensuring the water used in procedures is at a safe and comfortable temperature. For Sapphire Scientific, a leading provider of dental equipment, overheating rinse water posed a risk of scalding for patients. They sought a reliable solution to precisely control water temperature. Keystone collaborated with Sapphire Scientific to design a specialized valve that would mix cool water into the rinse system and prevent scalding.
Solution:
Keystone collaborated with Sapphire Scientific to design a specialized valve solution for their dental equipment. We engineered a valve system capable of precisely controlling the temperature of rinse water by mixing it with cool water as necessary. The valve was integrated into the heating tank of Sapphire Scientific’s equipment, ensuring precise temperature regulation and preventing overheating.
Outcome:
By incorporating Keystone’s valve solution into their dental equipment, Sapphire Scientific effectively addressed the challenge of preventing overheating of rinse water. The precise temperature control provided by the valve system enhanced the safety and comfort of dental procedures, minimizing the risk of scalding for patients. Sapphire Scientific benefited from improved performance and reliability of their equipment, enhancing the overall user experience and satisfaction.
