TECO chillers are used to maintain the correct water temperature for the Penguin Island display at Longleat Safari & Adventure Park in Wiltshire. Penguin Island is a 225,000-litre naturally-themed display which opened on Saturday 20 July 2013 and is home to a colony of captive-bred Humboldt penguins.

The Humboldt penguin (Spheniscus humboldti) is also known as the Peruvian penguin, or patranca; it gets its name from the cold water current it swims in, which was discovered by the explorer Alexander von Humboldt. Humboldt penguins are native to the coastal area of Peru and Chile in South America and are officially listed as ‘vulnerable’ by the The International Union for Conservation of Nature and Natural Resources; in 2012, they estimated that only 2,500 to 9,999 adults remain in the wild. Their ‘vulnerable’ status means that they are at immediate or imminent risk of becoming endangered. In the wild the penguins are under threat from climate change, overfishing and the acidification of the oceans.
