ENERGY MANAGEMENT INDUSTRY FOCUS
FUTURE-PROOF AND EFFICIENT SMART COOLING SAVES ENERGY
Transtherm Cooling Industries has been pioneering the technological advancement of commercial heat exchangers and cooling systems since 1989. Like other manufacturers today, it faces the challenge of designing machinery compatible with the Internet of Things (IoT), where users can remotely monitor and manage their equipment from anywhere

ith the Industrial Internet looming large on the horizon, Transtherm
partnered with Schneider Electric to future-proof its cooling systems, allowing for smart communication between machines and remote access, as well as energy efficiency and noise reduction gains. Headquartered in Coventry, Transtherm’s dry air blast cooler and adiabatic cooler machinery is supplied all over the world, and it serves customers in both the commercial and industrial sectors. Adiabatic cooling is the process of reducing heat through a change in air pressure caused by volume expansion. It is used extensively in data centres across the globe, where it often works in conjunction with naturally occurring cold air and water in a process known as free cooling. Along with data centres, the coolers are used in other buildings where operations take place around the clock, such as hospitals, universities, public buildings and retail environments. In 2015, these type of organisations demand complete visibility over their energy infrastructure, whereby safety features can be monitored, readings can be shared, and processes can be fine-tuned remotely. In order for Transtherm to achieve this, Schneider Electric dedicated HVAC M168 and M171 PLCs are embedded in the cooling systems. Two RS-485 Modbus connections allow a Modbus Master connection to provide effective communication to the internal aspects of the control systems, and a Modbus Slave only connection provides the customer with an option to communicate with the cooler from their BMS system. This enables them to remotely monitor energy usage, temperatures, and operational modes, as well as adjusting settings using control parameters bespoke to the cooler’s control systems. “Energy management is something our
customers are increasingly aware of, and remote monitoring and access of HVAC systems is a fantastic tool that gives organisations greater control over their estate,” says Nick Bound, managing director at Transtherm. “With Schneider Electric PLCs
embedded in our cooling systems, our customers benefit from a more connected energy infrastructure, where data can be harnessed to create a smarter, more efficient building environment. Having networked devices means greater communication amongst the cooling systems. We get smart cooling, whereby organisations have both the information and the ability to make continual improvements, reduce emissions, and save money.” Additional energy efficiency gains are
being made with the use of Schneider Electric drives, embedded within Transtherm cooling systems to reduce noise and power. The Altivar 212 is a variable speed drive for three-phase asynchronous motors from 0.75kW to 75kW. It is specifically designed for HVAC variable torque applications, and due to its eco-energy based design, energy savings of up to 70 per cent can be achieved compared to a traditional control system.
As a supplier to OEMs, Transtherm Cooling Industries continually drives towards providing the most reliable, high performance, innovative and energy efficient solutions to its customers
The installed drives also provide
machine fans with a longer life, as they facilitate a significantly softer start and stop of the cooling system’s motor. With multiple technical, environmental and financial benefits, the addition of Schneider Electric drives and PLCs means Transtherm has ultimately been able to sell more equipment. Furthermore, its customers have been able to make greater savings, while at the same time reducing their carbon footprints and future-proofing in an increasingly strict regulatory environment. Initial introduction of this product
With the number of connected devices expected to pass 17 billion in the next five years, connected energy infrastructure is becoming a necessity
range was made by Schneider Electric’s authorised distributor BPX Electro Mechanical. Director Roger Collins recalls: “Transtherm initially approached us with a view to improving the connectivity and scalability of their systems, as well as consolidating the number of components per panel. As they are a loyal customer of Schneider Electric industrial control products integrating the automation offer was an ideal progression. “We are delighted that the Schneider
Electric HVAC Controllers have proven so successful, and all parties are continuing to work closely to develop the offer.” Around 18 per cent of the UK’s carbon
emissions come from non-domestic buildings, and improving energy and asset management across them needs to be a priority. The UK has set targets to reduce greenhouse emissions to 50 percent of 1990 levels by 2025, and 20 per cent of 1990 levels by 2050. In order to achieve these goals, the industrial and commercial sectors need to adopt smart solutions that optimise energy management using data. Transtherm’s cooling systems, embedded with Schneider Electric technology, are indicative of the innovation required to meet these targets.
