text: thermic fluid working?   thermic fluid system work on closed loop principle and is the best solution for any heating need in process industry. in thermic fluid system, a synthetic / mineral based thermic fluid is circulated in the system using high temperature resistant pump and heat is one through combustion of fuel in main coils of the thermic fluid heater. the heat produced is then utilized by thermic fluid and then utilised in the process. the returning fluid coming out of the process is taken to uniquely designed expansion cum deaeration tank, where all system is made non pressurized. the fluid from expansion tank goes back to the pump again and the process is repeated. temperatures up to 300 deg. c can be achieved using thermic fluid systems.
