CEMLINE® Unfired Steam Generators are designed to produce clean steam with steam or high temperature hot water as an energy source for use where there is a need to produce clean steam from boiler steam or high temperature hot water.

A full line of water heaters that offer the perfect solution for any type of installation:

• where space is at a premium
• large capacity needs
• work in conjunction with condensing or speciality hydronic boilers
• for remote locations not requiring electricity
• solar powered

A STONESTEEL® Tank is constructed with a steel shell which completely supports a uniform, water-resistant lining of hydraulic STONESTEEL®. The rusting and corrosion common with steel tanks is prevented because the water touches only non-corrosive surfaces. The STONESTEEL® is applied in a continuous arch against the metal wall and will not be injured by ordinary use or handling.

CEMLINE Steel Tanks are manufactured in strict accordance with ASME code requirements and National Board Registration. Non-Code tanks are also available.CEMLINE Steel Tanks can be built in accordance with working pressures designed to suit particular jobs. Tanks are usually built 125 psig working pressure, but tanks with working pressure from 0 to 500 psig can be provided.

Cemline Blowdown / Condensate Coolers are designed to receive blowdown from a steam boiler, flash the blowdown to steam, and cool the condensate going to drain.

CEMLINE® Chilled Water Buffer Tanks (CWB) are designed to be used with chillers which do not have water volumes of sufficient size in relation to the chiller. The insufficiently sized systems do not have enough buffer capacity for the chilled water causing poor temperature control, erratic system operation and excessive compressor cycling.

Cemline primary/secondary buffer tanks improve system efficiency by preventing the problem of short cycling boiler(s). Low water content boilers operating at low loads will short cycle leading to sooting, premature component failure, and nuisance shut-downs. If the boiler is allowed to fire for a minimum of several minutes the full efficiency of the boiler can be achieved preventing sooting, premature

EMLINE Flash Tanks are used to flash steam from high temperature condensate prior to introducing into low pressure lines and to flash condensate prior to returning to the boiler or condensate tank. CEMLINE Flash Tanks are ASME code constructed and stamped for 150 PSI working pressure of carbon steel and have a prime painted exterior. Vessels are registered with the National Board.

CEMLINE® blow down/condensate coolers are designed to receive blow down from a steam boiler, flash the blowdown to steam, and cool the condensate going to drain. CEMLINE Blow Down/Condensate Coolers are ASME code constructed and stamped for 150 PSI working pressure. Minimum Steel thickness is 3/16″ where conditions require these vessels to be constructed with 1/4″, 3/8″ or ½” steel thickness.

The blow down enters the tangential inlet where it meets a 90 degree stainless steel wear plate. The wear plate will prevent erosion of the side wall of the vessel. The tangential blow down entry causes the blow down to swirl around the circumference of the vessel where part of the liquid will flash to steam and the balance will settle to the bottom. The internal flash will go through the vent to atmosphere and the hot condensate and sludge will fall to the bottom where it will flow by gravity to the drain leg.

The temperature of the condensate will activate the thermal control valve which will feed cold water into the drain leg where the cold water and hot condensate will mix. This results in drained liquid temperature which is acceptable for municipal sewage. The Blow down vessel is available without the condensate cooling leg.

CEMLINE® Replacement Tube Bundles for Storage Water Heaters and Heat Exchangers

Cemline builds Replacement Tube Bundles as exact replacement for all existing tube bundles. The Replacement Tube Bundles are readily available with standard 1 week shipment. Replacements available for Steam, Boiler Water, and High Temperature Hot Water Bundles.

Cemline standard replacement tube bundles are designed for a maximum working pressure of 150 psig and a temperature of 375 oF.
