Kondensor merupakan komponen yang penting pada PT. Pupuk Iskandar Muda .Unjuk kerja kondensor dipengaruhi oleh perpindahan panas yang baik, sehingga tekanan vakum pada kondensor dapat dijaga tetap tinggi. Kondensor 61-101 JTC telah dilakukan overhaul pada bulan Mai 2021 sehingga didapat data sebelum overhaul dan sesudah overhaul dengan data aktual yang diambil dalam 2 bulan kemudian dirata-rata. Data yang diambil merupakan data aktual yang didapat dari log sheet. Untuk mengetahui laju perpindahan panas total digunakan metode Logarithmic Mean Temperature Differential dan Number of Transfer Unit. Didapat LMTD terkecil sebelum dan sesudah overhaul masing-masing 7.08 C dan 5,5 C dan didapat nilai NTU sebelum dan sesudah overhaul masing-masing didapat 48,449 dan 51,649. Dan efesiensi setelah overhaul mencapai 84%. Yang mana telah meningkat sebanyak 19%. Diharapkankan dari hasil kondisi setelah overhaul harus lebih baik dari pada sebelum overhaul.

Condenser is an important component of PT. Young Iskandar fertilizer. The condenser's performance is affected by good heat transfer, so the vacuum pressure on the condenser can be kept high. Condenser 61-101 JTC has been overhauled in Mai 2021 so that data obtained before overhaul and after overhaul with actual data taken in 2 months then averaged. The data taken is actual data obtained from the log sheet. . To find out the total heat transfer rate is used logarithmic mean temperature differential and number of unit transfer methods. The smallest LMTDs were obtained before and after the overhaul of 7.08 C and 5.5 C respectively and NTU values before and after the overhaul were obtained at 48,449 and 51,649, respectively. And efficiency after overhaul reached 84%. That has increased by 19%. Expect from the results of the condition after the overhaul should be better than before the overhaul.
