Established in 1979, Highland Spring Group is the UK’s leading producer and supplier of natural source water. Now bottling over 600 million litres of water a year across five sites, the Highland Spring Group produces brands including Highland Spring, Speyside Glenlivet, Hydr8 and a range of private label flavoured and unflavoured waters for some of the UK’s major supermarkets and foodservice retailers.
Keep the operational temperature of the building; containing low and high-pressure compressors, associated treatment equipment and other process equipment at an optimal level
Heat generated in the plant room due to the many different pieces of equipment; high-pressure compressors, low-pressure oil-injected compressors and associated treatment equipment, chillers and dryers, along with increased external air temperatures during the summer months, meant the internal plant room temperature was rising to levels that could have lead to major problems causing a costly loss in production.
We analysed the area to establish the best product for the challenge and identified that the Eco-Power hybrid roof ventilation with additional air intake louvred panels. This product will extract process heat from compression appliances and allow fresh air intake at low level. Hybrid ventilation is defined as a 'two-mode' (or multi-mode) system that is controlled to minimise energy consumption, whilst maintaining acceptable indoor air quality and thermal comfort. It will work to ensure a constant supply of fresh air and combines natural ventilation with a high efficiency electronically commutated (EC) motor in a single unit to ensure reliable and on demand peak performance.
Eco-Power is capable of operating unhindered in natural wind mode or in both natural and energy efficient mechanical modes simultaneously. When required, performance is boosted by activating mechanical operation to ensure desired airflow rates are achieved. Even during mechanical operation, wind mode can improve flow rate performance.
We analysed the area again, post installation with a twelve minute temperature test. Deactivating the ventilators two minutes in and reactivating them six minutes later. The temperature rises dramatically as a result of deactivating the ventilators and reduce at a similar rate with the ventilators are reactivated.
The two EP900s achieve a total air turnover of 15 air changes per hour, this results in a cooler, more efficient compressor house all year round.
