HEAT PUMPS Range expansion with Auriga


New to the BAXI line-up is the Auriga medium temperature monobloc heat pump range with compatible cascade and hybrid controls, and a pre-contract design guidance service for its existing commercial heat pump offering. This series can achieve


temperatures of up to 60°C with reduced global warming potential (GWP) due to the R32 refrigerant. Available in single outputs of 20,


26, 33 and 40kW, and cascade options up to 320kW, the new Auriga series offers design


flexibility for commercial buildings of all sizes.


As part of the new Auriga range, Baxi


has launched a series of Auriga- compatible cascade and hybrid controls to maximise system efficiency. The new Baxi Commercial HVAC (CHVAC) Manager offers modular and flexible control of hybrid heating systems, with the option to cascade up to eight heat generators (either eight ASHPs or a combination of ASHPs and boilers). The


for simple ASHP cascade system control. The Baxi VM-T controller can be used as an extension to increase the number of secondary zones controlled. The CHVAC Manager also enables


connection to a BMS through Modbus or 0-10V for full remote monitoring and system optimisation. The Auriga is backed with a Parts


and Labour warranty up to 5 years when commissioned by Baxi or a


new Auriga indoor controller is designed Project1_Layout 1 08/03/2021 12:54 Page 1

Low GWP monoblocs feature R744


The next generation of natural refrigerant heat pumps from IDEAL HEATING COMMERCIAL feature maximum flow temperatures up to 70ºC. The ECOMOD CO₂ monobloc air source heat pumps also benefit from the low global warming potential (GWP) refrigerant R744, with a GWP rating of just 1. The heat pumps in the range come


in three outputs - 65, 95 and 130kW – with even higher outputs possible when installed in a cascade arrangement, where up to six can be centrally controlled, operating from an intelligent lead controller. A high performing unit, they can


operate at a design ambient temperature of -10⁰C, with a seasonal


Ground source model maximises efficiency for commercial applications


Available from MITSUBISHI ELECTRIC is a wide range of commercial heat pumps, including the Ecodan CRHV-P600YA-HPB monobloc ground- water source heat pump. This inverter driven model can


operate individually or as part of a multi-unit system for low temperature hot water and domestic hot water. With a flow range from 30°C to 65°C and a maximum flow temperature of 65°C at -5°C, the Ecodan CRHV can provide heating capacity from 60 to 960kW (with up to 16 units controllable in a single cascade system). The Ecodan CRHV system comes


with cascade and rotation functions built-in as standard, suiting it for a variety of commercial heating applications, such as schools, hospitals and leisure centres. It can connect to multiple heat sources, including boreholes, slinkies, aquifers, lakes, rivers, and waste heat. Passive

cooling is also possible by exchanging ground/water source with a chilled water system. Compression is delivered from two


compressors, so if a single compressor was ever to malfunction the other would continue to operate and provide 50% capacity. When used as a cascade system there is also the ability to rotate units based on accumulated run hours. Ground source heat pump systems,


like the Ecodan CRHV, have been used to good effect in educational facilities and similar applications where there may be


available ground resources. ■ les.mitsubishielectric.co.uk

co-efficient of performance (CoP) rating of 3 or better. Furthermore, ECOMOD CO₂ can achieve high temperatures up to 70°C, making them suitable for Domestic Hot Water (DHW) applications and district heating systems. ECOMOD CO₂ heat pumps are quiet


in operation, but for minimal background noise, a further model in the range - the CO₂Q - benefits from a quiet noise level as low as a 71dB(A) rating.


As with all ECOMOD heat pumps,


they can be installed alongside other Ideal Heating commercial solutions, including Evomax 2 and Imax Xtra 2 commercial condensing boilers, to build


a low carbon hybrid heating system. ■ idealcommercialboilers.com
