HVAC systems’ operation is a critical requirement for reopening and maintaining adequate safe indoor air quality (IAQ). The ASHRAE Epidemic Task Force developed guidance to help facility managers improve indoor air quality to slow the transmission of viruses via the HVAC system. Belimo has reviewed the ASHRAE Epidemic Task Force recommendations and developed a checklist to evaluate field devices’ operation. Non-functioning devices can be retrofitted to meet the indoor air quality requirements of the ASHRAE reopening guidelines.

Belimo’s ZoneTight zone valve is designed for maximum efficiency in tight spaces and sets performance standards for pressure dependent and pressure independent zoning applications. The QCV and PIQCV provide 95% less power consumption than conventional zone valves. The zone valve series easily connects to the actuator allowing operators and technicians to install valves quickly without tools, helping to reduce labor costs.

The new 22ADP-584A and the 22ADP-584B duct differential pressure sensors with true auto-zero functionality provide precise pressure measurement. The automatic calibration electronically adjusts the transmitter’s zero reference value every ten minutes. During the adjustment, the output and display values will freeze to the last measured value, eliminating output signal drift due to thermal, electronic, or mechanical effects. The device returns to its normal measuring mode after the one-second calibration process.

Leading by example is essential. Belimo's US headquarters installed a 900kW solar panel system. This installation is one of the largest rooftop solar panel installations in Connecticut! This project is an 877 kW solar electric array that interconnects directly into two of the facility meters here at Belimo. In total, this project will generate over 1,100,000 kWh of clean electricity in the first year, which is roughly equivalent to powering 100 Connecticut households for 12 months. By utilizing dormant roof space and investing in solar technology, Belimo is now self-generating approximately a third of its annual electrical consumption needs directly from sunlight. In addition to offsetting and stabilizing Belimo's operational expenses and grid-supply electricity needs for at least the next 25 years, this project serves as an essential asset to a world-class production facility.

Trusted flow measurement is essential in maximizing HVAC system efficiency and ensuring occupant comfort. Glycol prevents heat transfer fluids from freezing in heating, cooling, and air conditioning systems. In systems where pipework is exposed to the exterior environment – rooftop units, free cooling, cooling towers – and green energy applications, such as solar thermal collectors. Glycol is also used in district cooling systems – such as high rise properties where low-temperature energy networks serve several customers.

Land O' Lakes, Inc. is committed to environmental stewardship – leveraging sound science and state-of-the-art technologies to improve sustainability and conserve natural resources in its many operations throughout the globe. The company took steps to exemplify this commitment by improving energy efficiency at its corporate headquarters in Arden Hills, Minnesota. The majority of the headquarters' chilled water needs are handled by a single, closed-loop driven by a central chilling plant. The plant features two 300-ton centrifugal chillers (600 tons total). A total of six air handling units handle the cooling load for the headquarters – four in the office building and two in the R&D facility. When examining the operation of HVAC systems and equipment to identify areas where efficiency could be gained, Land O'Lakes, Inc. energy officials uncovered a costly issue in the AHUs' chilled water coils. Much of the time, Delta T across the coils was lower than its design specifications. In addition to increasing electricity costs due to over-pumping, this resulted in suboptimal heat transfer and significant inefficiency at the building level. After conducting a thorough review of piping, valves, and instrumentation, officials concluded various infrastructural improvements would have to be made—the process of searching for a solution, which eventually led them to the Belimo Energy Valve™.

You can break down the basic functionality of a classical Building Management System (BMS) system into three essential functions: control, monitoring, and configuration. Control algorithms look at sensor inputs and occupancy data to determine when to modulate or turn on and off valves, fans, and dampers. Monitoring allows viewing inputs, outputs, and diagnostic alarms in real-time or through historical logs to verify that the system is controlling as desired. The configuration is the process of changing settings and modifying how the algorithms are applied and to what data points. There is a fourth function, analytics, and optimization, provided by a secondary system with access to all of the same data as the BMS. Its purpose is to analyze patterns and trends in the data to provide meaningful indicators of building performance and provide opportunities for improvement.
