Sangamo timers and heating controls now offered in silver and black


E


SP made a significant investment in its Sangamo timers and heating controls last year to revamp the entire range and


introduce key features that would help boost the products’ energy saving properties. Now Sangamo has expanded the range further to introduce two additional new colour options across all products offered, and in doing so becomes the first company to offer a choice of colours across its traditional timers and controls product range. The full range of Sangamo Timer Controllers,


Thermostats, Programmable Thermostats and Programmers is now all available in a choice of three colours, with silver and black added to the original white finish – taking the full range up to 30 individual product lines. ESP believes this will satisfy a fast growing demand among end users and building owners for a departure from the usual white finish to add a more stylish look to an interior setting. Energy efficiency remains at the top of the agenda for the economy, businesses and householders. The Sangamo range of heating controls offers features that will assist with efficiency and performance and will ultimately help drive down energy usage and costs – a critical consideration for consumers at a time when energy prices continue to rise. The Sangamo offer can be broken down into four main product categories - Timer Controllers,


Thermostats, Programmable Thermostats and Programmers – with a total of 15 products making up the comprehensive range. The Timers collection of products is designed for simplistic ON/OFF manual or scheduled control for


heating and lighting applications. The range has been expanded with a total of three new products, each one introducing the addition of a fused spur switch for additional protection for high loads. The Thermostats range of products - designed for controlling heating system via an electronic sensor –


now totals five products. The Programmable Thermostat products are designed for controlling heating applications via an


electronic sensor or programmed schedule, and ESP has added one new product to this range. All thermostat products have been upgraded and now offer TPI (Time Proportional and Integral) control for heating efficiency. In addition, the programable thermostats include an optimization feature; Optimum Start/Delay Start and Optimum Stop, for extra efficiency. The Programmers are designed for heating and hot water controlled independently across separate


channels via a programmed schedule. A total of three products make up this range varying from 1-3 Channel options and including an optional service interval function to assist with Gas Safety Regulation compliance.

WEATHERITE COOLS WITH CONDAIR ME


he Condair ME evaporative humidifier is helping Weatherite reduce cooling system energy consumption for its data centre and telecoms clients by up to 80%. Condair’s evaporative humidifier is providing adiabatic cooling in


Weatherite’s innovative Adtec-D free air cooling unit. The Condair ME boosts the cooling capacity of the system, allowing the Adtec-D to fully replace the need for mechanical cooling in some applications. The Adtec-D is a self-contained, modular cooling system that can be located either


inside or outside of a building. In data hall or telecom environments, for most of the year it operates in free air cooling mode and uses the outside air alone to cool the internal environment. However, when the outside temperature rises to around 20°C, the Adtec-D switches to adiabatic cooling mode. The incoming air is then passed through the Condair ME, which evaporates water into the fresh air stream, cooling it by up to a further 12°C. By combining free air and evaporative cooling, Weatherite’s Adtec-D has recently been able to fully


replace DX mechanical cooling across more than 800 switchgear rooms for a leading UK telecoms provider. A total of around 1,500 Adtec-D units have been deployed in the project to date. A single legacy 30kW DX and free air cooling unit was consuming around 71,000kWh annually to maintain the required internal temperature, operating 24/7. The replacement 30kW Adtec-D cooling unit consumes just 14,000kWh to meet the same annual cooling load. This resulted in an 80% energy saving for the client, which is a significant 83.3MWh annual saving in electricity across the UK-wide retrofit project. Andy Lewis, Technical Manager at Weatherite commented, “The Adtec-D is an ideal retrofit solution


for telco or DC clients who wish to take advantage of free air cooling rather than continuing to operate DX chillers. Available in modules that can provide from 15 to 80kW of sensible cooling, the Adtec-D will typically operate with an energy efficiency ratio greater than 15, even at peak outputs. The evaporative cooling technology, supplied by Condair, ensures the Adtec-D can maintain the allowable ASHRAE conditions, even during the warmer months in a European climate without the reliance on F-gas refrigerants.” “Weatherite only uses the highest quality components in its HVAC solutions, and this includes Condair’s


evaporative humidifier. It certainly delivered on our specific requirements for operation, control and hygiene management, and we’ve been very pleased with the support offered by Condair in connection with this successful project.” Andy concludes. Dave Marshall-George, UK Sales Director at Condair, commented, “It’s a privilege to partner with Weatherite on such an innovative product that is helping the UK’s telecommunications sector meet its energy and sustainability objectives. As well as offering the most comprehensive range of humidifiers on the market, Condair has the ability to work with OEMs to create customised solutions. The evaporative humidifier incorporated into Weatherite’s Adtec-D is based on our standard Condair ME, but with some modifications to meet the project requirements. This project is an example of how Condair can develop innovative and flexible solutions for its customers.” Weatherite is a leading UK manufacturer of made-to-measure HVAC equipment, based out of the West Midlands. Operating for over 50 years, the company provides a range of AHUs, heat recovery systems, packaged rooftop equipment and air cooled chillers.

Carrier Adds Heat Recovery and Free Cooling Options Extending R-32 Scroll Chiller Energy Savings


M


ONTLUEL, France, 13 June 2022 – Carrier has introduced high-performance heat recovery and free cooling options to its AquaSnap® 30RBP air-cooled scroll chiller range on lower global warming potential (GWP) R-32 refrigerant,


providing even greater energy savings and further reducing operating costs for end users. Carrier is part of Carrier Global Corporation (NYSE: CARR), the leading global provider of healthy, safe, sustainable and intelligent building and cold chain solutions. Carrier was the first European manufacturer to introduce a fully optimised scroll


chiller range on R-32. AquaSnap units also have an outstanding seasonal energy performance ratio (SEER) for cooling of up to 6.62, reducing indirect greenhouse gas emissions resulting from energy use. The latest heat recovery and free cooling options extend energy savings, further reducing greenhouse gas emissions over the lifetime of the equipment. The heat recovery system enables chillers to produce domestic hot water up to 80deg C, while continuing


to provide cooling, useful for applications such as hotels, hospitals and industrial processes requiring hot water. The free cooling option makes use of favourable ambient and load conditions, harnessing free cooling from the environment to augment or replace mechanical cooling via the chiller’s compressors, reducing energy consumption and running costs. Two versions of free cooling are available. Partial free cooling is designed for applications with a variable


primary cooling load, such as offices and healthcare, which may also have a constant residual cooling need. Examples include computer suites or scanner facilities. The total free cooling option is designed for applications with a constant cooling need throughout the year, such as industrial processes and data centres. “Heat recovery and free cooling can deliver significant energy savings for most applications,” said Eric


Pollet, Marketing Product Manager, Chillers and Heat Pumps, Carrier HVAC. “Free-cooling is particularly valuable in higher latitudes, where cooler climates offer the greatest opportunities for harnessing natural ambient conditions rather than relying on mechanical cooling. Under these conditions, it is possible for free cooling to meet most of an application’s cooling needs, delivering huge potential savings for the end user.” Carrier’s hydronic-based free-cooling system automatically activates when the outdoor air temperature


drops 1 degree C below the chiller’s return water temperature, harnessing the full free cooling opportunity and maximising energy savings. For example in Berlin, the hydronic free cooling potential is 50 to 95% of annual chiller run-time, depending on the application. In more northern locations, the potential free cooling opportunity is even greater. If free cooling is not sufficient to meet requirements, a mixed mode – using both free cooling and mechanical cooling – is automatically activated, ensuring the cooling needs of mission critical applications are always met. Energy efficient solutions like the AquaSnap® scroll chiller with heat recovery and free cooling support


Carrier’s 2030 Environmental, Social and Governance (ESG) Goal of reducing its customers’ carbon footprint by more than 1 gigaton.
