JBL is truly cool!

Summer and winter are a good thing, but not for aquariums! JBL provides a remedy with its cooling concept.

In warm countries and in cold countries in summer, water temperatures sometimes exceed 29 °C. This spells trouble for many kinds of fish, and especially for aquatic plants. Ice cubes and cool packs in an aquarium aren’t really the solution. JBL utilises the physical effect of heat loss from evaporation to lower high water temperatures. The JBL Cooler consists of ventilators which are mounted in such a way that they blow an air current across the surface of the water. This increases water evaporation, which leads to heat loss. The heat loss from evaporation can decrease the water temperature by 2 – 4 °C. The evaporated water should NOT be replaced with mains water, as this would increase the mineral content (general hardness) of the water. It is preferable to use water from a reverse osmosis system Osmose 120 or distilled water. The JBL Coolers are available in three sizes which come complete with a mount for tanks of 60 to 300 litres.

Controlled cooling: JBL provides a control device with a temperature sensor (JBL CoolControl) for the JBL Cooler which switches off the Cooler when the set temperature has been reached. A dial is used to set the maximum temperature, and the control cable is plugged into the Cooler. As soon as the set maximum temperature has been reached, the JBL CoolControl supplies the Cooler with electricity and turns the electricity off again as soon as the temperature drops below the set maximum temperature. The JBL Cooler 100 and the JBL CoolControl are effective, reasonably priced alternatives for expensive cooling units if a 4 °C temperature reduction is enough and if the tank has a maximum of 300 litres.

Notificações PUSH da JBL

O que são realmente notificações push? Como parte do padrão W3C, as notificações Web definem uma API para notificações de utilizador final que são enviadas através das notificações do navegador para os seus dispositivos fixos e/ou móveis. Nos dispositivos finais, surgem notificações tal como o utilizador final as conhece das apps instaladas no dispositivo (por exemplo, e-mails). Nos dispositivos finais, surgem notificações tal como o utilizador final as conhece das apps instaladas no dispositivo (por exemplo, e-mails).

Estas notificações permitem que um operador de um website possa contactar os seus utilizadores enquanto estes tiverem o navegador aberto - independentemente de estarem a visitar o website no momento ou não.

Para poder enviar notificações Web Push, só é necessário um website com código de Web Push instalado. Assim, as marcas também podem utilizar várias vantagens das notificações push sem apps (comunicações em tempo real personalizadas no momento exato.)

As notificações Web fazem parte do padrão W3C e definem uma API para notificações de utilizador final. Uma notificação permite informar o utilizador sobre um acontecimento, por exemplo, um novo artigo no blogue, independentemente do contexto de um website.

Este serviço é disponibilizado gratuitamente pela JBL GmbH & Co. KG e pode ser ativado ou desativado de forma igualmente simples.
