ASME Code Constructed National Board Registered Storage Tank

CEMLINE Unfired Steam Generators are constructed and stamped in accordance with ASME code and bear the UB stamp as required by the ASME code. All vessels are registered with the National Board of Boiler and Pressure Vessel Inspectors and a compliance certificate is furnished. Unfired Steam Generators to generate steam 40 psig or greater will be 100% X-Rayed and heat treated in accordance the ASME code

Stainless Steel Construction

CEMLINE Unfired Steam Generators can be constructed of stainless steel when no condensate is returned and there is 100% make up, such as in steam humidification. A stainless steel USG would also be used to provide steam for sterilizers, food processing, pharmaceutical, and clean room applications where deionized or reverse osmosis water is used as feedwater.

Carbon Steel Construction

CEMLINE Unfired Steam Generators can be constructed with a carbon steel shell and steel components. These Unfired Steam Generators would typically be used when the condensate is returned to the boiler and there is little or no make up water. Carbon steel Unfired Steam Generators are typically used in building heating systems and in humidification where the feed water is not corrosive.

Fiberglass Insulation

CEMLINE Unfired Steam Generators are furnished with 3" thick fiberglass insulation. This high quality insulation is an extremely reliable means of minimizing heat loss.

20 Gauge Steel Jacket with Hammertone Enamel Finish

CEMLINE Unfired Steam Generators are neatly and attractively covered with a 20 gauge steel jacket over the fiberglass insulation. The jacket protects the insulation and is professionally painted with superior quality enamel which provides an easy to maintain surface.

Structural Support Skid Base

CEMLINE Unfired Steam Generators are mounted on a structural skid designed as a permanent base. This skid is pre-engineered to allow correct support for the Unfired Steam Generator.

ASME Pressure Relief Valve

CEMLINE Unfired Steam Generators are provided with one or more ASME Section I pressure relief valve(s) sized to relieve the total BTU input of the heating coil.

Boiler Steam Pressure Gauge

CEMLINE Unfired Steam Generators are furnished with a large, easily readable pressure requirements.

U-Bend Coil

U-bend coils are constructed with copper, copper nickel, or stainless steel tubes. The selection of tubing material depends upon specific job requirements. The sizing section of this interactive catalogue will assist in selecting the correct tubing material.

Gauge Glass

CEMLINE Unfired Steam Generators are furnished with a gauge glass to allow monitoring of the water level in the vessel.

Steam Separator

A Steam Separator is factory supplied to dry the steam prior to being introduced into the clean steam line.

High Pressure Cutoff

CEMLINE Unfired Steam Generators are furnished with an adjustable high pressure cut off wired to close the control valve in the event of over pressure. The high pressure cut off also has an adjustable differential.

Level Control/Low Water Cutoff

CEMLINE Unfired Steam Generators are furnished with a combination feed water control/ low water cut off. This level control will allow the correct water level to be maintained in the vessel and will also shut the generator down in the event of low water.

Feed Water Solenoid with Check Valve

As the boiler makes steam, it is necessary to replenish the boiled off water. A solenoid valve, which opens and closes from the water level controller signal, is required. A solenoid feed system requires the feed water pressure must be at least 10 psi greater than the steam pressure in the Unfired Steam Generator. If there is less than 10 psi pressure differential, a feedwater pump must be used. A check valve is supplied between the solenoid valve and the unfired steam generator.

Solid State Operating Control

CEMLINE Model 2001 Solid State Steam Control Module incorporates operating and limit functions in one solid state controller. The controller features a LED display of the pressure and on board settings of high and low pressure safety cut off and alarms. The 2001 SSCM simplifies the control of the Unfired Steam Generator, enhances the look of the product, and follows industry trend to solid state controls.

Alarm Bell

An alarm bell is furnished to sound an alarm in the event of either low water or high pressure. An alarm silencing relay allows manual pressing of a button to silence the alarm bell, but red warning light remains on until the alarm condition is corrected.

Remote Start/Stop

This feature allows the Packaged Water Heater to be started or stopped from a remote location. Typically this would be accomplished from the Building Automatic System (BAS). Requires a dry contact suitable for 24 Vac and 1 amp.
