CSM-K

High capacity clean steam generator

Description

The CSM-K range of high capacity clean steam generators has been designed to provide sterilizer grade clean steam from suitably treated feedwater using plant steam as the heating medium.
Units using other fluids on the heating media can be provided to special order.
The range covers outputs up to 3 800 kg / h.
The pressure vessel is manufactured in accordance with PED 97 / 23 / EC and is supplied with a standard package of documentation.
The primary medium passes through a tube bundle which can be extracted for cleaning and maintenance.
All secondary wetted parts are manufactured from 316 stainless steel.

Applications

Suitable for process applications, laundries, food and beverage applications, hospital sterilizers, laboratories and humidification.
The CSM-K can also be used in a number of electronic production processes, pharmaceutical and general biotechnological applications.
Please refer to our general sales brochure on clean steam for information on other products that can be used in association with the clean
steam generator.

Technical data

Pneumatics	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	Electrical requirements: 400 V 3-phase 50 Hz. A fused isolator of the correct rating must be incorporated in the supply line as near as possible to the unit. Information on the installed load for each individual unit will be supplied by Spirax Sarco.
Feedwater quality	To meet the requirements of HTM 2031 we would recommend the use of de-mineralised or reverse osmosis feedwater. It is advised that analysis of the feedwater is undertaken prior to installation and commissioning. Whilst not mandatory the table opposite gives a guide to recommended typical values.	Property	Maximum value
		Ammonium	0.2 mg / l
		Heavy metals substitute	0.1 mg / l
		Feedwater Chloride	0.5 mg / l
		quality Nitrate	0.2 mg / l
		Residue on evaporation	30.0 mg / l
		Phosphate	0.1 mg / l
		Silicate	0.1 mg / l
		Electrical conducivity at 25°C	35.0 µS / cm
Control	The unit is PLC controlled with the generator having pressure and level control.

Dimensions

Dimensions (approximate in mm) and standard output production (approximate in kg / h)
Standard output production is based on the following conditions:
– Primary steam pressure 10 bar g;
– Clean steam pressure 3.5 bar g;
– Feedwater inlet temperature 20°C
Engineering drawings, including holding down details, will be provided after ordering ‘for approval’ and as ‘final certified’ (as built).
