Compressor energy recovery: turn wasted heat into energy savings
Compressing air makes heat. In fact about 94% of the energy a compressor draws ends up as heat, and only around 4% stays in the air as the pressure that actually runs your plant. Most factories throw that heat away through their cooling systems. It is one of the largest pools of recoverable energy on site, and it usually goes straight out the roof, because older compressor designs cannot capture enough of it, or cannot deliver it hot enough to be useful.
Tamturbo treats energy recovery as a design principle, not an add-on. Our compressors reclaim up to 90% of input energy as heat. Standard Heat Recovery (SHR) and Boost Heat Recovery (BHR) turn that into hot water up to 90 °C (194 °F) for boiler make-up water, wash-down, heating moulds, production materials or the building itself. An optional Heat Management Unit (HMU) regulates the temperature to whatever your process needs.

Turn Compressor Heat into Usable Energy
Tamturbo has revolutionized this process by designing an optimal cooling system for energy recovery. By capturing the heat management process at various stages and employing liquid cooling for critical components like frequency converters, electric motors, and turbo heads, Tamturbo compressors recover up to 90% of input energy as heat. This advanced system is a built-in standard feature, ensuring maximum energy efficiency. For even greater performance, our patented Boosted Heat Recovery (BHR) delivers liquid temperatures up to 90°C (194°F), suitable for a variety of production processes.
Integrating energy recovery into a plant system has often been a challenge, but Tamturbo makes it seamless with our Heat Management Unit (HMU). This compact module simplifies connections between the compressor and the plant, minimizing installation work and making heat energy integration easy and cost-effective. Tamturbo transforms wasted heat into a valuable resource, driving efficiency and sustainability in your operations.
Be careful with recovery percentages that look too good
Some manufacturers advertise recovery figures above 100%. Their real recovery is closer to 70–80% of the energy used. The higher numbers come from cherry-picked inlet conditions: when the incoming air is warmer than the cooling liquid, the compressor behaves like a heat pump and pulls in extra energy, which inflates the percentage. When the inlet air is cooler, the same trick works against you. Tamturbo bases its recovery percentages on standard compressor inlet conditions and does not lean on heat-pump behaviour to dress up a brochure.
What this means for your numbers
Energy is the biggest line in a compressor’s total cost of ownership. Recovering up to 90% of it as usable heat offsets other energy you buy for boilers, washing and heating, and it counts toward your emissions and efficiency targets at the same time
Frequently asked questions
How much energy can a compressor recover as heat? A Tamturbo compressor recovers up to 90% of its input energy as heat at standard inlet conditions, as a built-in standard feature.
What can I use the recovered heat for? Hot water up to 90 °C (194 °F) for boiler make-up, wash-down, heating moulds and production materials, facility heating and other process needs.
What is the difference between SHR and BHR? Standard Heat Recovery (SHR) captures heat at standard levels. Patented Boost Heat Recovery (BHR) raises the liquid temperature to 90 °C for more demanding processes.
Why do some competitors claim over 100% recovery? Those figures rely on inlet conditions that let the compressor act as a heat pump. At standard conditions, real recovery is nearer 70 to 80%. Tamturbo quotes standard conditions.
