Process heat requirement constitutes a large part of global energy demand. Solar thermal harnesses heat from the sun that can be effectively used for process heat requirements, and save upto 30% cost when compared to conventional energy sources like gas, diesel, electricity etc. HMX offers solar thermal solutions for steam generation and high-temperature hot water for a range of applications such as process heating, CIP (clean in place), pasteurization, distillation, cooking, air heating, etc., across industries and commercial establishments.
