Oil/Water safety heat exchangers type AMFS

Version with/for double pipes
Protection against overpressure as well as corrosion effects.
Expansion tank with pressure control for acceptance of changes in sealing liquid volume
Removable sealing cover for cleaning internal water pipes

Safty principle

Based on the existing oil/water heat exchangers of the AM series, the company Universal Hydraulik have developed the new oil/water safety heat exchanger AM/SF which, by means of a double tube, prevents the danger of mixing the cooling and the to be cooled medium. The space between the two tubes is filled with a sealing liquid.
A pre-charged piston-type accumulator compensates the thermal change in volume of the sealing liquid and keeps the sealing liquid pressure almost constant.
Any leaks in the bank of tubes are indicated at once by the pressure switches.
These two characteristics, the pre-charging of the system in connection with the min. and max. pressure monitoring guarantee an independent operating pressure for the cooling of as well as the to be cooled medium.

Sealing liquid

A special liquid enables optimum heat transfer. It is frost-resistant up to -30°C and, at the same time, safe with foodstuffs. Other liquids on request.
