Control

Compressed air: A 6 bar g compressed air

supply is required; where this is unavailable

an optional compressor can be supplied with

the unit (at extra cost).

Electrical requirements: 400 V 3-phase

50 Hz ( + NEUTRAL). A fused isolator must

be incorporated in the supply line as near

as possible to the unit.

If the CSM-PD is to form part of a system

to meet the HTM 2010 and HTM 2031

requirements we would recommend

operating at >85°C and using the following

feedwater quality/purity.

Whilst not mandatory the table below gives

a guide to recommended typical values.

Safety information, installation and maintenance

For full details see the Installation and Maintenance Instructions

supplied with the unit.

For spares information refer to the Installation and Maintenance

Instructions supplied with the pre-heating and degassing package.

Typical specification

The CSM-PD package is to provide a clean or pure steam

generator designed and built to produce steam to the HTM 2031

standard. The operating condition of the steam generator is to

raise 600 kg/h of clean steam at 3 bar g when supplied with

plant steam at 8 bar g. The CSM-PD will provide a minimum of

20 minutes autonomy. All items are to be pre-assembled and

mounted on to a skid base.

Sizing

Sizing is totally dependant upon the clean steam generation

requirements (secondary, clean steam production flowrate)

For exampe: A clean steam generator producing 600 kg/h clean

steam will require a CSM-PD500.

That is: 600 kg/h multiplied by a factor of 0.33 = 200 kg/20 min =

CSM-PD500 (working capacity = 370 litres).

How to order

Example: 1 off Spirax Sarco CSM-PD500 pre-heating and

degassing package.

Please provide details of primary steam pressure, clean steam

pressure, clean steam flowrate, feedwater system and flowrate.

Ancillary items to be used depending on installation:

- Isolation valves

- Separators

- Strainers

Other items may be required, please contact Spirax Sarco to

discuss the full installation.
