Mitsubishi Electric extends e-series


26 November 2018
Mitsubishi Electric has added 150kW and 180kW modules to its range of inverter-driven, e-series modular chillers to expand the ‘off-the-shelf’ offering to the UK market.
The e-series offers low noise levels and high part-load efficiencies with an operating range between 8-100% capacity to provide controllable, energy efficient cooling and heating with reduced plant size and features and benefits taken straight from the company’s experience in the air conditioning industry.
Available as cooling-only or heat pump versions, the new modules included a Y-shaped design to increase the intake of air and offer a greater heat exchanger surface area. With four inverter compressors operating as two pairs in each module and the ability to connect up to six individual modules into one system, the e-series chillers provide a versatile solution.
Marketing manager Graham Temple said: “We’ve had significant interest in these modular units since we launched the e-series three years ago and these larger modules expand the number of applications and buildings that can benefit from these advanced chillers.

“When you compare the UK market to the Japanese market, which is dominated by modular inverter-driven systems, you can see that the UK is heading for high performing, low carbon solutions that can also help reduce space requirements.”
The new units have a smaller footprint than the existing 90kW e-series modules and each can be positioned in a bank of up to six connected units using the same internal header, saving on piping space and equipment costs.  This also allows for smaller plant space and easier servicing than traditional chillers.
The models deliver a Seasonal Efficiency Energy Rating (SEER) of up to 4.62 and the ability for units to operate on their own or in tandem with others. With full rotation and back-up function available, the operating time for each module in the same system can be equalised to prolong operating life and performance.
The e-series also achieves some of the quietest noise levels on the market which is increasingly important in inner city locations.  These low noise levels are achieved through both the unique construction and design of each unit as well as the advanced component technology within each chiller, which is also easily integrated within new and existing systems using BEMS control.
