Mitsubishi Electric has announced the launch of its latest air-source chillers and heat pumps, developed by the company’s Italian factory.
The new range offers an R32 air-cooled chiller (the MECH-iS-G07) and an R32 air source reversible heat pump (the MEHP-iS-G07). Both are manufactured to the exacting standards of quality associated with the company’s Mitsubishi Electric Quality, produced in Italy for the first time.
Both systems are highly efficient, and operate using R32 refrigerant, which has a lower GWP (global warming potential) of 677. The new range features variable speed scroll compressors, and are available in seven sizes. Each system is also available in three modules to offer a cooling capacity range from 50 to 220KW.
MEHP-iS-G07, the new reversible heat pump, offers high efficiency at partial loads, and its silent nature and compact design make it the ideal solution for comfort applications, including hospitality venues such as hotels. As well as producing hot water for comfort heating applications up to 65°C, it offers domestic hot water production even at very low outdoor temperatures down to -20°C.
The MECH-iS-G07 chiller is designed for process and IT cooling. With the ability to produce cold water across a wider range of temperatures -12 down to -20°C of outdoor air temperature, and with extremely reliable components that can offer 24/7 cooling, it provides an efficient solution for any process application. When used alongside indoor CRAH (Computer Room Air Handler) units, the MECH-iS-G07 offers the first fully hydronic IT Cooling package for small and medium enterprise data centres, ready to pave the way to the forthcoming hydronic transition of the sector.
Exclusive to these new chillers are the Mitsubishi Electric VSD (Variable Speed Drive) scroll compressors, which are optimised for R32 refrigerant and offer high seasonal efficiency, continuous capacity modulation, stable leave water temperature, and perfect and accurate load delivery in all working conditions. Four innovative models of compressor are available on three different performing chassis to offer flexibility of design and operation.
Simon Prichard, Product Strategy Manager for Central Plant, explained that “At Mitsubishi, we know the absolute quality of every component and part within our products. Everything has been looked at from the design of the axial fans to the materials used in the coils and coatings, so that we can deliver the products and lifetime performance that our customers expect.”
The new models are also designed using the Japanese ‘Poka-Yoke’ system design, which roughly translates as ‘mistake proofing’ or ‘avoiding unexpected surprises’. Each element has been examined to ensure connection and installation is as straightforward and error-free as possible: “Colour-coded connectors and different shaped pins ensure that each PCB connection avoids any possibility of error,” adds Prichard, “Quick couplers for the fans also help to reduce connection time and ensure safe and pressure-tight connections.”
These plug and play solutions offer in-built reliability and ease of maintenance due to their ultra-accessible service ports. With integrated pump kits and buffer tanks, the units are also designed to make modular installation more straightforward. They also offer advanced controls, including a new smart defrost algorithm, a new touch screen control panel, and the KIPLink, which allows Mitsubishi Electric products to be controlled remotely from smartphones, tablets, or notebooks.
About Mitsubishi Electric
Complex IT environments are often characterised by variable cooling loads which require a high cooling capacity at full load in order to allow the IT equipment to operate correctly when it is most needed.
Our IT Cooling range makes it possible to keep temperature and humidity constant even with very wide load variations ensuring the correct room conditions all year round.
