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
The keys to sustainable heating with electrically driven industrial heat pumps
- Consider what temperature you really need. Heat pumps delivering above 100 °C typically operate at about half the efficiency of those delivering below 90 °C.
- A system with a natural refrigerant like ammonia, CO₂, or hydrocarbons ensures future-proof investment, with ammonia typically offering the highest efficiency.
- Ensure the system uses modern technology like plate heat exchangers for low refrigerant charge and efficient temperature approach, reducing payback time.
- Choose a reliable supplier of plate heat exchangers. Alfa Laval latest developments are focusing further efficiency gains in heat pump applications.
Tesnilni sistem RefTightTM
Visokozmogljivo tesnilo za delo pod visokim pritiskom. Tesnilni sistem RefTight™ omogoča izboljšano dolgotrajno delovanje pri opravilih, kjer sta potrebna visok tlak in temperatura. Zvar je nameščen zunaj utora obroča in tesnila, kar zagotavlja zanesljivo tesnjenje ter podaljšuje življenjsko dobo tesnila in servisne intervale.
Integrirano podhlajevanje
Večina hladilnih sistemov porabi velike količine električne energije; energetsko učinkovita zasnova pa ima velik potencial za prihranek stroškov. Integracija podhlajevanja v kondenzator ploščnega toplotnega izmenjevalnika omogoča izboljšanje energetske učinkovitosti kompaktnih toplotnih izmenjevalnikov brez potrebe po dodatnih ceveh ali sestavnih delih.
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
Energy efficiency potential in industrial heat pumps
Did you know that more than 50% of primary energy is lost as waste heat? However, industrial heat pumps can capture and reuse waste heat for buildings and industrial processes.

Advanced solutions for industrial heat pumps
Lotani prenosniki toplote
Naši bakreno lotani izmenjevalci so kompaktna in učinkovita rešitev za ogrevanje, hlajenje, izhlapevanje in kondenzacijo, ki jih lahko uporabljate za širok nabor aplikacij, ter ne potrebujejo nobenega vzdrževanja. Delujejo z večino vrst okolju prijaznih hladilnih sredstev z nizkim potencialom globalnega segrevanja, vključno s pomembnimi naravnimi hladilnimi sredstvi, kot na primer CO2 in ogljikovodiki. Vsaka enota je zasnovana z vrsto edinstvenih funkcij, ki zagotavljajo vrhunsko toplotno zmogljivost in zanesljivost.
AlfaNova
Večina ploščnih izmenjevalcev za komercialno in industrijsko hladilništvo z majhnimi zmogljivostmi je lotana z bakrom. Čeprav so primerni za številne aplikacije, baker negativno reagira z amoniakom, ki je pomembno naravno hladilno sredstvo. AlfaNova, ki je izdelan z našo edinstveno metodo fuzijskega lepljenja, je edini 100-odstotni ploščni toplotni izmenjevalnik iz nerjavnega jekla. Ta predstavlja zelo kompaktno in učinkovito rešitev za hlajenje zelo čistih in občutljivih tekočin, ki učinkovito izkorišča potencial amoniaka z nizkim potencialom globalnega segrevanja.
