Heat recovery boiler for milk cooling systems
Capture the wasted thermal energy from milk cooling and transform it into usable hot water, maximizing energy efficiency in your dairy operations while reducing utility costs.

Recovers Heat and Cools Milk Efficiently
The ECOTEMP 300 and 500 from The SERAP Group are specialized heat recovery units designed to optimize energy use in dairy farms and milk processing plants. These units efficiently recover and store heat generated during milk cooling, converting it into viable energy for heating water up to 50°C in your milking parlour. The system utilizes a stainless steel heat exchanger and a pressurized storage tank, ensuring durability and long service life due to its duplex stainless steel construction, renowned for its corrosion resistance. Capable of seamless integration with single or dual refrigeration units, ECOTEMP achieves optimal energy recovery, offering a dual-purpose solution as both a heat recovery unit and a hot water storage system. These units provide a rapid return on investment and come with an optional 3000 W electrical resistor for additional heating requirements. Suitable for use in dairy processing operations, the ECOTEMP units support continuous and manual operations, making them an ideal choice for handling liquid products like chilled and pasteurized milk, and contributing to energy savings and improved process efficiency.
