Prednosti
- Enostavna montaža: Grelniki vode Alfa Laval Aalborg s tremi prehodi dimnih plinov so izdelani po načelu priključi-in-poženi, zato imajo ob dobavi že vgrajen gorilnik, nadzorno ploščo, armaturo in kable.
- Kompaktna oblika: Zaradi majhne delovne površine se grelnik vode enostavno priključi na vsak sistem.
- Enostavno preverjanje in vzdrževanje: Priključki in ventili so nameščeni na vrhu grelnika, kar omogoča enostaven dostop ob montaži, preverjanju in vzdrževanju. Številne vhodne odprtine olajšajo preverjanje notranjosti.
- Enostavno čiščenje: Spiralne cevi se enostavno očisti, poleg tega jih je zaradi velike učinkovitosti malo.
- Konstantno visoka kakovost pare: Učinkovit uparjalnik zagotavlja suho in nasičeno paro. Dodatno je na voljo pregrevalnik.
- Boljše izgorevanje: Gorilna komora ima sorazmerno nizko razmerje oddajanja toplote in zagotavlja veliko prostora za plamen. S tem se izboljša izgorevanje in izpust dima.
