Low Return Vacuum heating unit with a combination air and water pump that performs both the condensate and vacuum pumping functions. Multi-jet design proven to be effective and reliable means for removing air and lifting hot condensate in the return system. A standard cast iron receiver is provided with a standard 20-year warranty against corrosion failure for years of service. Standard unit designed for applications with low returns and system capacities ranging up from 2, 500 square feet EDR; air pumps range up from 3 cubic feet per minute (cfm) at 5-12" HG at 160F. Unit completely packaged, including electrical controls. Units are available in either simplex or duplex configuration with either 1750 RPM or 3500 RPM motors in either single or three phase. Pumps are flange mounted to the receiver and equipped with industry standard motors. Pumps bronze-fitted with removable bronze wearing ring and with mechanical seals rated for temperatures up to 250F. Higher temperature seals and special faces available upon request.

Type .005 DA-2C atmospheric deaerators are recommended for high-pressure boiler applications. The standard .005 design removes dissolved oxygen to a maximum level of .005 cubic centimeters per liter of feed water. Two-compartment design is typically used: on systems having more than 20% return hot condensatewhere floor space may not be sufficient for a two-tank designwhen a complete, factory-packaged unit is preferred instead of field wiring and piping of freestanding surge tank and deaeratorThe two-compartment design enables the flash steam that escapes the deaeration compartment to be recovered by the direct contact vent condensor in the accumulator compartment. This method allows minimal vent loss. Standard deaerator receivers available in black steel. The complete unit can be plasite-lined or made of 300 series stainless steel. Unit can built to handle a wide range of flows and pressures; receiver can be customized in terms of diameter, length and height to meet job specific requirements. Number of pumps on unit depends upon number of boilers to be supported and stand-by specifications. Pump motors can be either 1750 RPM or 3500 RPM, single or three phase. Unit equipped with single stage or multi-stage pumps depending upon operating conditions. Pumps bronze-fitted with industry standard motors and mechanical seals rated for temperatures up to 300F. Higher temperature seals and special faces available upon request. Pumps can be mounted in either a vertical or horizontal orientation. Unit equipped with direction steam injection assembly with stainless steel preheat tube; assembly includes temperature regulator that can be either pneumatic controlled or self-contained. Other accessories include but not limited to gauge glass assembly thermometer, inlet strainer, butterfly isolation valve, low-water cut-off or alarm switch, electrical control panels and tank insulation.

he Air Break Tank (ABT-H) unit comes standard with either a simplex or duplex bronze fitted Pump & Motor assembly and a 316" thick black steel receiver. Receivers are available in three popular sizes30 gallon, 50 gallon and 100 gallon. All receivers have a gauge glass assembly, a low-water cutoff float switch and a solenoid valve and float switch assembly with an air gap. Air break tank units provide a positive air gap fitting to eliminate back flow and possible contamination of water supply. It is used anywhere system water loss is present. The unit functions as an air break tank when the optional float switch and solenoid valve are supplied with an air gap fitting. Excellent for process loads, cooling towers, hydronic applications or anywhere loss of water necessitates make-up because they provided a detached central make-up supply reservoir.

Blowdown Tanks (BDT) are ASME code stamped for 150 psig (minimum 516" thick). These vessels provide an alternate way of cooling the bottom boiler blowdown. The tank is designed to break up the blowdown flow by hitting the tangential stainless steel wear plate in the vessel. Unit can be fitted with optional after cooler. Various sizes and shapes are available to meet your specifications.

A Blowdown Separator reduces the boiler blowdown water (along with chemicals and dirt) to atmospheric pressure and cools its temperature before being piped into a drain. Tanks can be built as vertical orientation with stand. Tanks made of heavy-duty steel with stainless steel wear plates and designed to 150 or 300 psig with national board stamp. An optional manual or automatic after cooler is available. Various sizes are available.

Glycol Fill Tanks come with an air gap fitting to eliminate back flow that might contaminate the water supply. Unit can be used to add glycol to a system or Seal Flush Unit. Design comes standard with either simplex or duplex, bronze-fitted pumps and 316" thick, black steel tank; an option for heavier thickness is available. Standard unit also includes a removable lid, gauge glass assembly and low water cut-off switch.

Steel Horizontal Vacuum and Condensate unit with independent air and water pumps. Multi-jet design proven effective and reliable for removing air and lifting hot condensate in the return system. A standard heavy gauge black steel receiver from 316" to 38" thick provided for years of services. Receiver is divided into two compartments: one side is used for collecting hot condensate and the other side is the vacuum chamber. Standard unit designed for applications with system capacities ranging up from 1, 000 square feet EDR; air pumps range up from 6 cubic feet per minute (cfm) at 5-12" HG at 160F. Unit completely packaged, including electrical controls. Units are available in either simplex or duplex configuration with either 1750 RPM or 3500 RPM motors in either single or three phase. Pumps are flange mounted to the receiver and equipped with industry standard motors. Pumps bronze-fitted with removable bronze wearing ring and with mechanical seals rated for temperatures up to 250F. Higher temperature seals and special faces available upon request. Air and water pumps can be sized separate for customized applications that standard unit configurations can not meet. Type SHVM is the boiler feed unit version of the SHVC. An electrical solenoid make-up water valve with float switch control is standard. A low water cut-off switch is furnished to prevent pumps from operating should the make-up water assembly fail to prevent the pumps from running dry and burning up the mechanical seals. Numerous options are available.

Vertical Flash Tanks or Horizontal Flash Tanks or Flash Recovery Vessels are used to reduce high-pressure steam to a low-pressure state before returning the steam in your system. Tanks can be built with a horizontal or vertical orientation with a stand. Horizontal design is available without a stand for hanging. Tanks made of heavy-duty steel and designed up to 150 psig with national board stamp as standard; other ASME stamped ratings available upon request. Various sizes available.
