Snellman is a pioneer user of industrial heat pumps

| Oilon is a good partner for Snellman

Snellmanin Lihanjalostus Oy (Snellman Meat Refinement) in Pietarsaari is one of the first companies to use industrial heat pumps for waste heat recovery. Today industrial heat pumps from Oilon produce a remarkable share of heating energy at Snellman’s plant.

On year 2007 – before anybody actually even talked about industrial heat pumps – Markus Snellman, technical manager at the Snellman meat processing plant, discovered that a lot of energy was wasted with the hot water used for washing that could be recovered with a heat pump. 1 MW heat pump was installed to recover this waste heat and to heat up washing water to +55 °C. The result was a saving of approximately 450000 kg of heating oil per year; a semi-trailer load each month.

The next big step was taken in 2009. More heat pumps were installed and those utilize heat from cooling machines and produce +75°C water for heating the plant. “We made small changes, installed heat exchangers before the condensers on the roof and were able to recover much more energy. And we got it every hour, not just during work shifts 16 hours a day like with grey water,” says Snellman.

The last step is two Oilon ChillHeat industrial heat pumps installed in January 2019 producing a temperature of +95 °C. It is needed, for example, for sterilizing knives and other tools which requires a temperature of at least +82°C. The heat is also used for drying spaces after washing. The refrigerant in the pumps is R1234ze, which has almost zero GWP value.

“When we install a heat pump we save the environment and also money. Last year we saved 580 000 Euro. And we save it every year!”

 

EHPA invites everyone to submerge themselves in the possibilities that heat pumps are capable to offer in several industrial sectors. To read more stories the updated booklet is currently available on EHPA’s website.
