Abstract

"PROCESSO E DISPOSITIVO DE DETECçãO DE ESCAPAMENTO EM UM TROCADOR DE CALOR, NOTADAMENTE COM PLACAS". Esse dispositivo para a detecção de um escapamento entre os dois circuitos de um trocador com placas (1), do tipo que compreende meios para encher de fluido sob uma pressão diferente, cada um dos dois circuitos é caracterizado pelo fato de compreender meios de controle automático da aproximação das pressões nos dois circuitos em relação a um limite determinado e meios de assinalamento de um escapamento em função, quando os meios de controle automático tiverem constatado essa aproximação.
