Series AM.

Karalex AM1250 Assembled 3
The AM Series machines are constructed using 4 absorbsion vessels
where 2 are in the absorbsion phase whilst the 2 remaining are in the
cooling and regeneration phase.
The AM Series of machines have a powder coated finish to exterior
surfaces with stainless steel utilised on the internal surfaces. Moving
parts within the construction have been reduced to two permanently
connected disc valves. The valves are rotated using a directly coupled
gear motor and distribute the air into the four adsorber vessels. The
valves are turned ¼ revolution every 15 minutes approximately.
The AM Series is supplied with a specially designed timer that controls
the valve change and engagement of the regeneration heating. The
machines are supplied with all safety equipment and come prepared to
be integrated with external hygrostat operation.
The AM Series machines are supplied to be floor mounted and come complete with all
necessary frames for installation. The machines are supplied as standard with a built in fan, inlet air filter and an outlet flange to allow connection to an air distribution system if required.
