Industrial heat pumps
Alfa Laval innovates compact plate heat exchanger technology for heat pump systems. These are installed to recover heat from industrial processes but also recover low-grade heat from data centers and natural heat sources like sea, river, sewage, or groundwater. We work closely with leading local installers and system builders from across the globe, supplying both standard and customized heat exchanger solutions. We focus largely, but not exclusively, on applications that employ natural refrigerants.
We have experience working with both electrically driven as well as thermally driven heat pumps type so do not hesitate to contact Alfa Laval for advice regarding appropriate heat exchanger selection
Alfa Laval walks the talk - An ammonia heat pump absorbs the waste heat from the cooling system of the plate pressing operation in the Alfa Laval factory. Benefitting plate heat exchangers, it contains an ammonia charge of only 40 kg for a capacity of 827 kW with a COP of 7. >> Read more about the case.
A heat pump equipped with efficient Alfa Laval plate heat exchangers enables waste heat recovery from municipal wastewater and seawater, supplying a district heating network that serves 1100 homes in Nyhavn, Copenhagen with sustainable heat. The result is major energy savings and emissions reductions.
The keys to sustainable heating with electrically driven industrial heat pumps
- Think through what temperature you really need the heat pump to deliver. A level above 100 C reaches normally only 50% of the efficiency of a heat pump delivering below 90 C.
- Choosing a system with natural refrigerant such as ammonia, carbon dioxide, or hydrocarbons will assure the investment stays future proof. Ammonia normally allows for the highest energy efficiency.
- Assure the system is optimized with modern technology including plate heat exchangers allowing for low refrigerant charge and a close efficient temperature approach which shortens the system’s payback time.
- Choose a reliable supplier of plate heat exchangers. Alfa Laval latest developments are focusing further efficiency gains in heat pump applications.

Zavar je pozicioniran izvan posebnog žleba prsten-zaptivka, što obezbeđuje pouzdano zaptivanje, produžava vek trajanja zaptivke i produžava servisne intervale.
Integrisano pothlađivanje
Većina rashladnih sistema troše ogromne količine električne energije; energetski efikasan dizajn može rezultirati značajnim ekonomskim uštedama. Integrisanje pothlađivanja u kondenzator pločastog izmenjivača toplote omogućava poboljšanje energetske efikasnosti kompaktnih izmenjivača toplote, bez potrebe za dodatnim cevovodom ili dodatnim komponentama.
Turn to efficiency
Alfa Laval plate heat exchangers can operate with the same small temperature difference as evaporators. To fully benefit this efficiency, we have developed the U-Turn separator. This efficient module is also very compact, and the connections are grouped to allow the module to be installed close to walls or on the perimeter of a main skid.
- Designed for natural ammonia refrigerant
- Minimum pressure drop losses, maximum energy efficiency
- Close temperature approach, space saving design
- Complete solution including our heat exchanger and separator technology

Poluzavareni pločasti izmenjivači toplote
Naši kompaktni poluzavareni izmenjivači toplote omogućavaju još veću efikasnost i pouzdanost u primenama u industrijskom hlađenju koje koriste amonijak kao rashladno sredstvo sa niskim GWP. Alfa Laval poluzavareni izmenjivači toplote su takođe pravi izbor za kaskadne sisteme koji rade sa CO2 kao sekundarnim medijumom za primene u zamrzavanju. Ovi izmenjivači smanjuju punjenje amonijaka i takođe sprečavaju rizik od unakrsne kontaminacije sa svojim dokazanim RefTight™ sistemom zaptivanja.
Lemljeni pločasti razmenjivači toplote
Naši pločasti razmenjivači toplote lemljeni bakrom su kompaktno, efikasno rešenje koje ne zahteva održavanje za grejanje, hlađenje, isparavanje i kondenzaciju u širokom spektru primena u rashlađivanju. Oni rade sa većinom tipova ekološki prihvatljivih rashladnih sredstava sa niskim GWP, uključujući važna prirodna rashladna sredstva, kao što su CO2 i ugljovodonici. Svaka jedinica je osmišljena sa nizom jedinstvenih karakteristika koje obezbeđuju vrhunski termički učinak i pouzdanost.
AlfaNova
Većina pločastih izmenjivača toplote koji se koriste u komercijalnom ili industrijskom hlađenju malog kapaciteta lemljeni su bakrom. Iako je pogodan za mnoge primene, bakar negativno reaguje sa amonijakom, važnim prirodnim rashladnim sredstvom. Zahvaljujući našoj jedinstvenoj metodi fuzionog spajanja, AlfaNova nudi jedini na tržištu pločasti izmenjivač toplote od 100% nerđajućeg čelika. To je kompaktno, efikasno rešenje za hlađenje veoma čistih, osetljivih tečnosti, koje koristi prednosti niskog GWP potencijala amonijaka.
