Hi, i am new for this site, im from Indonesia so im sorry if my english is hard to understand.
I wonder if someone could help me, i have a basic question, when do we need to use electrical defrost and when do we need to use hot gas defrost??
All i know is hot gas defrost is cheaper than electric defrost, and if we use electric defrost in a freeze room, room temp. will be affected dramatically... Is this statement's right : we better to use hot gas defost for pump evaoprator only??
