CSSB All Stainless Steel Steam Boilers are specifically designed for use where the purity of the heating fluid must be maintained. Typical applications include sterilizers and autoclaves in research, biological and pharmaceutical laboratories and humidification equipment for the electronics industry (solid state substrates).

CSSB boilers utilize de-ionized, demineralized or distilled water to provide pure steam, free of minerals or undesirable chemical additives. Pure steam eliminates the possibility of carry over of contaminants into the process.

Note — A water feed system supplying distilled, de-ionized or demineralized water is required on all CSSB boilers. (See Caution note in Optional Equipment Section.)

Stainless Steel Construction — Pressure vessel and all wetted parts are made of 304 stainless steel for operation with pure water. Type 316 stainless steel construction is available.

Low Water Cutoff and Level Control — Float type constructed of stainless steel automatically maintains correct water level in the boiler and shuts down the boiler if the level drops below safe operating limits.

Operating Controls — All stainless steel pressure controls provide accurate regulation of steam pressure.

High Pressure Limit Control — All stainless steel manual reset pressure limit control shuts down boiler if operating pressure exceeds set point.

Water Level Sight Glass — Furnished with stainless steel valves, provides for constant visual observation of the water level in the boiler.

Pressure Gauge, Safety Valve, Drain and Blow Down Valves are constructed of stainless steel for compatibility with basic boiler.

CSSB Steam Boilers are Trimmed at 100 psig for operation to 90 psig and come complete, factory tested and ready to operate. Boilers are available (on order) with 15, 30 and 50 psig. All catalog CSSB boilers are UL Listed.

All optional equipment (except blow down separator) is available in stainless steel construction for compatibility with the basic boiler.

Auxiliary Low Water Cutoff uses vertical ball float with electronic control. This option is required by some state or local boiler codes.

Proportional Control with electronic solid state sequencer for modulated pressure control.

Low or High Pressure Water Feed System (Required) for mounting on boiler or remote installation.

Heavy Duty Vacuum Breaker prevents siphoning of condensate from condensate return systems.

Automatic Blow Down System eliminates need for daily manual blow-down maintenance.

Blow Down Separator for blow down of a boiler where steam and hot water cannot be discharged directly into a drain. Blow down separator uses city water for cooling.

CAUTION — The use of chlorinated or regular tap water in stainless steel boilers is specifically prohibited by the ASME Code. The feed water for CSSB boilers must be distilled, de-ionized or demineralized water with a minimum specific resistivity of 1 megohm/ cm. Failure to use the correct type of water will damage the equipment and void the factory warranty.
