A.O. Smith PHE Copper Soldered Plate Heat Exchangers Series
A.O. Smith PHE Series: High-Performance Copper Soldered Plate Heat Exchangers (50-275 kW)
The A.O. Smith PHE Series represents a line of high-efficiency, copper soldered plate heat exchangers designed for optimal performance in various heating applications. This series offers a range of models with nominal outputs from 50 kW to 275 kW, catering to diverse heating requirements in both residential and commercial settings.
Key Features:
- Wide Power Range: The PHE Series includes eight models (PHE 50, 75, 100, 150, 175, 225, 250, and 275) with power outputs ranging from 50 kW to 275 kW, ensuring a suitable option for various system sizes.
- Efficient Heat Transfer: All models operate with a primary temperature of 80/60°C and a secondary temperature of 10/60°C, providing efficient heat transfer for domestic hot water production or other heating applications.
- Optimum Security: The double separation construction ensures maximum safety in operation.
- High Pressure and Temperature Tolerance: With a maximum working pressure of 25 bar and a maximum working temperature of 120°C, these heat exchangers are built to withstand demanding conditions.
- Durable Construction: The heat exchanger plates are made of AISI 316 L stainless steel, known for its excellent corrosion resistance, while the soldering material is copper, ensuring long-lasting performance.
- Compact Design: Despite their high power outputs, these units maintain a compact form factor. All models share the same height (337 mm) and width (127 mm), with only the depth varying from 61 mm to 205 mm depending on the model.
- Flexible Installation: The compact size and consistent dimensions across the series allow for easy and flexible installation in various settings.
- Low Maintenance: The absence of gaskets in the design contributes to reduced maintenance requirements and increased reliability.
- Customizable Insulation: An additional insulation kit is available for each model, allowing for enhanced energy efficiency in different environmental conditions.
- Scalable Solutions: The series offers a progressive increase in capacity, number of plates, and flow rates, allowing for precise system design and scalability.
- Chlorine Tolerance: All models can withstand a maximum chlorine concentration of 50 mg/kg at 80°C, making them suitable for various water quality conditions.
