THRUSH
Frequently asked questions
Common questions about THRUSH from 3G Electric.
What is the difference between a THRUSH U-tube heat exchanger and a THRUSH replacement bundle?
A THRUSH U-tube heat exchanger is a complete assembly that includes the shell, tube bundle, and connections, ready for installation in a steam-to-water heating system. A THRUSH replacement bundle consists of the U-tube bundle only, designed to fit a specific heat exchanger model. For example, SKU 60WT11 is a replacement bundle compatible with model TS06-048-222BS-SSCI-SX-CCC-11-3352, which corresponds to SKU 60WT19. Replacement bundles are used when the original heat exchanger's shell and connections are still serviceable but the tubes require replacement due to fouling, corrosion, or mechanical damage. The bundle part number and the compatible heat exchanger model number are both listed in the product data to ensure correct matching.
What flow rates and heat dissipation capacities are available in the THRUSH U-tube heat exchanger line?
The THRUSH U-tube heat exchangers supplied by 3G Electric cover water flow rates from 26 gpm to 145 gpm and water heat dissipation ratings from 254,000 BtuH to 1,414,000 BtuH. Specific examples include SKU 60WT18 at 26 gpm and 254,000 BtuH, SKU 60WT19 at 44 gpm and 429,000 BtuH, SKU 60WT21 at 49 gpm and 478,000 BtuH, SKU 60WT22 at 82 gpm and 800,000 BtuH, SKU 60WT24 at 145 gpm and 1,414,000 BtuH. These ratings are for steam-to-water heat transfer and are based on specific steam and water conditions. Actual performance may vary with operating temperatures, pressures, and fluid properties. Consult the individual product data for each SKU when selecting a unit for a given duty.
What materials are used in THRUSH U-tube heat exchangers and replacement bundles?
THRUSH U-tube heat exchangers and replacement bundles in the 3G Electric catalog use copper tubes. Copper is a common material for steam-to-water heat exchangers because of its high thermal conductivity and general resistance to corrosion in many water systems. The tube material is specified in the product data for each SKU. Other wetted materials, such as the shell and tube sheet, may vary by model and are not detailed in the available specifications. For applications involving aggressive water chemistry, high chloride levels, or other corrosive conditions, verify material compatibility with the manufacturer's guidelines or a qualified engineer before selecting a copper-tube unit.
How do I identify the correct THRUSH replacement bundle for my heat exchanger?
To identify the correct THRUSH replacement bundle, locate the manufacturer model number on the heat exchanger nameplate. The replacement bundle product data lists the compatible manufacturer model number and the corresponding 3G Electric SKU for the complete heat exchanger. For example, if your heat exchanger model is TS08-036-2XXXX-SSCI-SX-CCC-11-5552, the compatible replacement bundle is SKU 60WT13, which is also compatible with SKU 60WT21. If the nameplate is missing or illegible, the flow rate and heat dissipation rating can help narrow the options, but the model number is the most reliable identifier. Contact 3G Electric with the model number or the original 3G Electric SKU to confirm the correct bundle.
What applications are THRUSH steam-to-water U-tube heat exchangers used in?
THRUSH steam-to-water U-tube heat exchangers are used in hydronic heating systems, domestic hot water generation, process water heating, and industrial fluid heating. In hydronic heating, they transfer heat from steam to a water loop that serves radiators, air handling units, or radiant floors. For domestic hot water, they provide a separation between the steam system and potable water. In process and industrial applications, they heat water or other fluids for manufacturing, cleaning, or other operations. The U-tube design allows the bundle to be removed for cleaning or replacement, which is useful in applications where water quality may cause fouling. The copper tube construction is suitable for many non-aggressive water conditions.
Does 3G Electric provide technical support for THRUSH heat exchanger selection?
3G Electric supplies THRUSH U-tube heat exchangers and replacement bundles and can provide the product data available for each SKU, including flow rate, heat dissipation, tube material, and compatibility information. For selection assistance, 3G Electric can help match a replacement bundle to a heat exchanger model number or confirm the specifications of a particular SKU. However, final selection for a specific application should be based on the system requirements, including steam pressure, water flow, temperature rise, and water quality. 3G Electric does not provide engineering design services, but can facilitate access to manufacturer documentation when available. Contact 3G Electric with the required duty or existing model number to request a quote or additional information.
