Réglage vanne gaz
chauds

Afin 

d’éviter tout risque de gel des échan-

geurs à plaques brasées, les groupes
LJA  - LJAH sont équipés de vannes gaz
chauds.
Le réglage usine est prévu avec de l’eau
pure.
En fonction du réfrigérant et de la tempé-
rature de congélation du fluide calopor-
teur utilisé, le tableau ci-dessous indique
le réglage à effectuer sur site.

Adjustment of hot gas
valve

To avoid any risk of freezing in the brazed
plate exchangers, LJA and LJAH units
are fitted with hot gas valves.

The units are factory-adjusted for pure
water.
Depending on therefrigerant liquid and its
freezing point, the table below shows the
setting to be made on site.

Regelung des Gasventils

Um jede Frostgefahr  für die gelöteten

Plattenwärmetauscher zu verhindern, sind die

Kaltwassersätze LJA   LJAH mit Warmgasventilen

ausgestattet.

Die werkseitige Einstellung erfolgt mit reinem

Wasser.

In der nachstehenden Tabelle ist die Einstellung

vor Ort in Abhängigkeit vom Kühlmittel und dem

Gefrierpunkt des verwendeten Kältemittels

aufgeführt.
