Xylem has announced the addition of four new Bell & Gossett BPX brazed plate heat exchangers to its line of large plate heat exchangers. The 3” and 4” brazed plate heat exchangers, models BP432, BP433, BP434, and BP435, are ideal for large hydronic heating applications, refrigerant evaporators, condensers with large chillers and many other applications requiring flow rates up to 800 GPM, the manufacturer has claimed.

The company lists the following product features and advantages:

• The compact, low-cost units with innovative corrugated plate design provide very high heat transfer coefficients.
• The heat exchangers use stainless steel plates and are vacuum brazed together to form a durable product that withstands both high pressure and high temperature.
• All four models have a design pressure of 435 psig, min/max design temperature of 310/450°F, lifting lugs, and support/mounting feet.
• Additionally, all models are designed in accordance with ASME Section VIII, div. 1 and include a “U” stamp as a standard offering.
• They provide high rates of heat transfer, which requires less surface area than conventional shell and tube exchangers. Other advantages of the BPX heat exchangers versus conventional shell and tube units include:
• One-sixth the size
• One-fifth the weight
• Uses only one-eighth the liquid
• Requires one-third to one-fifth the surface area

According to Xylem, the new models are available for selection and pricing in the System Syzer selection and configuration software.
