Viessmann has introduced the Vitocal 200-A and Vitocal 222-A, with innovative noise-reduction technology. Both operate so quietly that they are suitable for densely built-up areas such as terraced housing estates, and both have high energy efficiency with low operating costs. Both heat pumps feature Viessmann’s new Advanced Acoustic Design. This combines a sound-optimised fan designed to harmonise the acoustic frequency range with intelligent speed control to reduce airborne noise at full- and partial-load operation. This effectively stifles the lower frequency sound of conventional heat pumps which can be perceived as disturbing. The result is that the pumps are barely audible: noise pressure in night mode at a distance of three is a mere 35 dB(A). Installation of the Vitocal 200-A and 222-A is easy. No minimum distance is required between the indoor and outdoor units, no refrigeration leak test is required because the cooling circuit is hermetically sealed, and no F-gas certificate is needed because the connect- ing pipes to the outdoor unit are filled with water. These new heat pumps are also simple to operate, via the Vitotronic 200 control unit with its easy-to-read plain text and graphic display. Controls can be altered anywhere via the Vitoconnect web interface and free ViCare smartphone app.
info-uk@viessmann.com Heat Interface Units maintained remotely over the internet
Evinox Energy has introduced remote commissioning and warranty validation for their ModuSat heat interface units (HIUs), which can significantly reduce the cost of commissioning and time spent on site by engineers manually checking and adjusting settings. Many other heat interface units for communal and district heating developments require an engineer to physically attend site to set-up every individual unit manually. Evinox’s electronically controlled ModuSat HIU’s feature SmartTalk communication technology and can be connected over the internet to remote servers, enabling Evinox to check the operation of each unit remotely and adjust settings where required. Once ModuSat units are installed and ready to be commissioned the following quick and simple process takes place: Installer Registers ModuSat Units Using Evinox’s Online Registration Portal; Evinox Check the Operation of Each ModuSat Unit remotely; Evinox Visit site to inspect a sample of units (Around 10 per cent of the total units); Evinox will then certify the units and issue certificates; The Warranty period begins. The benefits don’t just end there! Evinox’s SmartTalk® communication system enables them to carry out scheduled maintenance checks remotely over the internet.
