Chilled Water Pumps

Chilled Water Pumps are vital components in HVAC systems. They are centrifugal pumps that circulate chilled water from the chiller to air handling units (AHUs) and fan coil units (FCUs), and back. They play a crucial role in maintaining comfortable indoor temperatures by transferring heat from the building to the chiller. These pumps are typically of the end suction or horizontal split casing type, chosen based on the specific flow, head requirements and design of the system.

Make up pumps

Make up pumps also known as pressurization Units maintain the required water volume and pressure in closed-loop HVAC systems. We offer both static and dynamic pressurization units designed to maintain stable pressure in closed-loop HVAC systems while compensating for water losses due to evaporation, leakage, or drainage. These units help prevent air ingress, cavitation, and pressure fluctuations, ensuring system reliability. Additionally, our pressurization units are capable of performing the degassing process, efficiently removing dissolved air and microbubbles from the water. This enhances heat transfer efficiency, reduces corrosion, and improves overall system performance, making them an essential component of HVAC hydronic networks.

Air Separator/ Degassing Units

Air Separators are critical in HVAC hydronic systems, removing trapped air and microbubbles from the circulating water to improve heat transfer efficiency and prevent issues like corrosion, noise, and cavitation. They are typically installed at points of high temperature and low pressure, where air naturally separates from water. Available in centrifugal, coalescing, and combination types, air separators enhance system reliability, reduce maintenance needs, and improve overall HVAC performance. In addition to traditional air separators, we also offer a compact vacuum degasser, which effectively removes dissolved gases that standard air separators cannot extract. This advanced solution further improves system efficiency, prevents oxidation-related damage, and ensures long-term operational stability.

Expansion vessels

Expansion vessels are essential components in HVAC hydronic systems, designed to absorb pressure fluctuations caused by thermal expansion. They prevent excessive pressure buildup that could damage pipes, pumps, and other system components. Available in diaphragm or bladder-type designs, these vessels maintain system stability by accommodating expanding water, reducing the need for frequent pressure adjustments. Properly sized expansion vessels enhance system efficiency, minimize energy losses, and extend the lifespan of HVAC equipment.

Valves & Accessories

HVAC systems rely on various valves and accessories to regulate flow, maintain system balance, and protect equipment. Triple Duty Valves combine check, balancing, and shut-off functions in one unit, reducing installation space and complexity. Suction Diffusers ensure smooth water flow into pumps while filtering debris and eliminating air pockets, enhancing pump efficiency. Pressure and Temperature Gauges provide real-time monitoring to detect fluctuations and optimize performance. Isolation Valves, such as butterfly, ball, and gate valves, allow for maintenance without system shutdown. Air Vents and Vacuum Breakers prevent airlocks and negative pressure buildup, ensuring smooth operation. Strainers remove debris to protect pumps and heat exchangers from clogging. Together, these components enhance system efficiency, reliability, and longevity while reducing maintenance needs.

Monitoring and Control

Monitoring and control systems are essential for optimizing HVAC performance, improving efficiency, and ensuring reliable operation. Programmable Logic Controllers (PLCs) provide centralized automation, enabling real-time monitoring, fault detection, and remote control of pumps and valves. Variable Frequency Drives (VFDs) adjust pump and fan speeds based on demand, reducing energy consumption and wear. Sensors, including pressure, temperature, and flow sensors, continuously collect data to optimize system performance and detect anomalies. Together, these technologies enhance energy efficiency, extend equipment life, and provide greater system reliability and control.
