C Oi V Ee R A K O R G w n M S T IN Y ably. Features such as this required the universality of the PLC. Five high-efficiency condensing boilers were installed. The five units have 96% efficiency along with modulating output and can allow for variation between 100,000 up to 1.776 million BTU per hour, only allowing 4% waste heat loss out of the flue. Should the solar and chiller heat source become depleted, the five boilers (see photo at right) will sustain hot water supply in unison or separately, depending on demand, while the integrated controls rotate boiler duty-call, preventing uneven service hours between the units. Having five boilers also provides mechanical redundancy. Should any one of the boilers require service, the others will continue operation, preventing hot water downtime, which can be critical during harvest, especially in cold weather. Electricty consumption is paramount when producing wine on a commercial level. Pumping hydronic solutions is a major electrical draw, therefore recent improvements in variable frequency drive (VFD) pump technology have proven key in this application. In regards to older hydronic technology, the standard operating procedure Five 370k BTU per hour boilers providing 96% efficiency, redundancy and versatility are mounted on a wall to conserve floor space. Heat recovery chiller (left) produces much needed hot water as a by-product. was to size pumps for peak demand and not allow for a lower horsepower setting, should demand be less than maximum during off-peak periods. With variable-frequency-drive (VFD) pumps, the power consumption scales back as demand decreases, minimizing hydronic electrical consumption. With off-peak periods being a majority of the year, the annual electrical energy-savings will be substantial. VFD pumps also allow for very accu- Hot Water From the Sun If your business requires hot water, Solarix Systems can help you reduce operating costs by using energy from the sun.
