Optimum cooling and heating, always exactly where they are needed

People who stay in hotels know how important a comfortable room climate is. At the newly built 4-Star-Superior Hotel Melchior Park in Würzburg, Germany, the builders therefore opted for electronic pressure-independent 6-way zone valves of the Belimo ZoneTight™ product family. These "All-in-one" control units measure the flow electronically and automatically ensure the correct amount of water when differential pressure changes occur. The integrated pressure release function guarantees maximum plant safety. This means that an optimum distribution of heating and cooling is ensured at all times.

New chiller with communicative PR actuator - Reliability, security and energy efficiency achieved with Belimo

A reliable cooling circuit is particularly important for the pharmaceutical company SwissCo Services AG in Sisseln (CH). The temperature and above all the humidity in the production plants are decisive for manufacturing the company's effervescent and tablet products. Alongside reliable operation and keeping temperature and humidity levels constant, the aim of refurbishing the cooling plant was to optimise energy consumption.

Where precision and flexibility go hand in hand

The new Logistikcenter 4 of Galliker Transport AG in Dagmersellen delivers unparalleled energy efficiency. In terms of heat technology, the entire logistics centre is totally autonomous and is therefore setting new standards in environmental technology and sustainability. Foodstuffs, but also pharmaceutical products, can be kept in ideal storage conditions in an area covering 22,000 square metres in an automated deep-freeze, high-bay warehouse and various storage spaces with different temperature zones.

The Belimo Energy Valve™ also monitors energy consumption too

It's not just patients with heart conditions that are being monitored in the new clinic Zan Mitrev for cardiology in Skopje, Macedonia. Since its opening on 1 March 2016, it has also been possible to monitor the flow of energy by using the Belimo Energy Valve™.

The construction work carried out by Bouygues Bâtiment Nord-Est started at the beginning of 2015. One part of the building is intended for administration purposes and theother for logistics.

Belimo Energy Valve Plays Integral Role in Land O’ Lakes, Inc.’s Corporate Facility Upgrade

Land O’ Lakes, Inc.’s Corporate Sustainability Group began making plans to upgrade the facilities in order to increase efficiency and reduce energy consumption. HVAC systems were a particular area of focus due to the fact that as the buildings aged, they became more difficult to cool and meet desired discharge air temperature set points (especially in the summer months). Improving occupant comfort was also a priority.

After conducting a thorough review of piping, valves, and instrumentation, officials concluded that in order to solve the problem, various infrastructural improvements would have to be made. They then began the process of searching for a solution, which eventually led them to the Belimo Energy Valve™.

Belimo and Optimum Energy Test Energy Valve’s Ability to Sustain HVAC Performance

Since its establishment in 1975, Belimo has innovated a number of major developments in HVAC actuator technology and became a worldwide leader in the HVAC industry. With its partner, Optimum Energy, a member of the U.S. Green Building Council and specialists in data-driven HVAC energy optimization for campuses and large facilities, a pilot project was undertaken at the headquarters of one of Optimum Energy’s Fortune 100 clients. The purpose was to test the impact of the award-winning Belimo Energy Valve on longterm sustainability by combatting HVAC system problems associated with low Delta-T.

Measuring, controlling, balancing and shutting with a single valve unit

The DonauSplash indoor swimming pool in Tulln, which was originally constructed in 1974, was reopened after almost a year and a half of general renovation in October 2014. The entire building technology was updated as part of the general renovation and a conversion from natural gas to biomass district heating was implemented. Efficient utilisation of energy was the motto of the building technology consulting engineers – after all, the heating output is about 500 kW. About 30 m³ of water is moved every hour in order to control the temperature of the individual bathing zones. The electronically controlled Electronic Pressure-Independent Valve (EPIV) from Belimo provides a tight seal in order to prevent energy losses in the water circuits, and increases efficiency during planning, implementation and operation.

The objective of this renovation was to modernise all the technical installations for the air conditioning and electrical systems. For heating and cooling an area of 27,000 m² has been equipped with combined heating/cooling ceilings. The Eqho tower now has 80,000 m² of office space, providing jobs for around 5,300 people.

Belimo’s EF Spring Return Actuators Serve as Economical Alternative to MS41xx Series Actuators

During the replacement process, a number of different actuators were examined and after careful consideration the decision was made to replace the failing units with Belimo’s EFX120-S N4 spring return actuators. In addition to having a NEMA-4 rating, Belimo’s EF actuators offered higher torque (270 in-lbs) in a single direct-coupled unit, and because of this, only 150 actuators were required to do the work that the 250 MS41xx units originally did (one EF unit can effectively operate a 66 sq ft damper). The cost for the more robust EF actuators was almost equal to the cost of ordering 250 M-Series actuators.

University of New Brunswick, Canada Efficiency that fits to a T

Low Delta T occurs when the supply and return chilled water temperature across an HVAC system is less than the chiller’s design calls for. This was evident on two separate structures at the University of New Brunswick in Fredericton, Canada, where Belimo Energy Valve™ helped achieve real-world savings through optimization of chiller operations.

Hartford, Connecticut’s most iconic building also may be one of its most difficult to heat and cool. The corporate headquarters of The Phoenix Companies, Inc. at One American Row in downtown Hartford is a true architectural landmark. The 13-story building, designed by famed twentieth-century architect Max Abramovitz and completed in 1963, is the first New England office building to be both LEED certified and on the National Register of Historic Places. However, the building’s ship-like profile and glass curtain walls cause tremendous solar gain, creating ongoing heating and cooling challenges for Phoenix.

Pressure Independent Valves Make Cost Effective Alternative to Reverse Return System for US Census Bureau

It was right there in black and white. Paraphrased, the guideline stated that pump and piping systems shall be arranged in a reverse return configuration. The standard is part of the GSA’s (US General Service Administration) design guide, known as the PBS-P100, and serves as the guideline for all US governmental buildings. However to all rules, there are at least one or two exceptions. Such was the case with the new US Census Bureau headquarters located in Suitland, Maryland. The 8-story, 1.5 million sq. ft. facility, scheduled to be completed in October 2006, simply was not a good candidate for the use of reverse return for all systems.
