Ambient Vaporisers

Ambient vaporisers have been developed so that low grade heat sources may be used to vaporise liquid CO2 from bulk storage vessels.

Description

Each ambient vaporiser consists of two units – the heat exchanger assembly and the electrical control box: 

The heat exchanger element consists of finned copper tubing to maximise heat transfer, designed and tested to the maximum bulk liquid CO2 storage vessel operating pressure of 24 bar.

The separate electrical control unit is usually wall mounted adjacent to the heat exchanger assembly. Each of the two heat exchangers is controlled by a solenoid valve on the inlet. Only one exchanger vaporises CO2 at any one time allowing the other to defrost for maximum efficiency.The switching time is controlled by a timer, enabling the vaporiser to operate 24 hours a day. The whole assembly is enclosed in a galvanised steel cover with powder coated paint finish. Detachable end covers give easy access to the control valves and electrical connections. A rigidised aluminium drain tray collects condensate for piping away. Defrost heaters are available as an option to allow operation of the vaporiser at low temperatures. The heat exchanger assemblies can either be suspended from the ceiling, mounted on a framework, or floor standing using optional legs (25000031 or 25000032 for Model L700).
