Dalam penggunaan material plastik sebagai komponen dan spare part, dan di industri otomotif kini banyak menggunakan mesin pencetak palstik dalam pembuatan produk. Pada proses pencetakan plastik diperlukan pendinginan baik itu mesin dan juga cetakannya (mold) agar terhindar dari kerusakan atau deffect yang terjadi akibat suhu yang terlalu panas sehingga mengakibatkan terganggunya proses pencetakan. Salah satu proses pendinginannya adalah menggunakan sistem cooling tower sebagai alat dan air sebagai media fluidanya, yang berguna untuk menjaga dan menstabilkan suhu pada mold dan mesin. Dalam proses pendiginannya, Cooling Tower memiliki beban, effisiensi, penggunaan make-up water dan persentasinya, serta effek yang diakibatkan jika suhu mesin terlalu panas pada mold atau mesin. Pada analisa didapatkan suhu maksimal yang baik untuk cooling tower dari segi beban, effisiensi, make-up water, dan effek nya agar proses pencetakan dapat berjalan dengan baik. Effisiensi (%) yang baik untuk beban cooling tower pada analisa adalah suhu T1db 33°C kelembapan 80%, dan suhu T2db 36°C kelembapan 90%. Make-up water yang paling ekonomis pada cooling tower pada analisa dengan suhu T1db 33°C dan T2db 36°C dengan kelembapan 80%, dan 90%.Downloads
