Product catalog summary

Overview: The document provides comprehensive information on Bowman swimming pool heat exchangers, designed for use with boilers or solar panels. These exchangers efficiently heat swimming pool water and are suitable for various water types, including chlorine water, seawater, and spa pools.

Specifications: Bowman heat exchangers are made with corrosion-resistant cupro-nickel tubes and bronze end covers, offering durability and longevity. They support heating capacities up to 145 kW or 500,000 BTU/h and include standard mounting brackets. The maximum working pressure is 6 bar, and the maximum working temperature is 100°C.

Maintenance: The design allows easy maintenance with removable end covers and tube stacks for cleaning, a unique feature of Bowman heat exchangers.

Cooling Functionality: These exchangers can also cool pool water in hot climates by using water from a chiller instead of boiler or solar panel water.

Product Range: The document details two main product ranges: one for boilers and another for solar panels, with specific models like 3705-3, 3706-2, and 3707-2 highlighted. Options for thermostat pocket end covers are available.

Performance Table: A performance table assists in selecting the appropriate heat exchanger based on pool size, flow rates, and desired output, assuming an 8-hour cycle with pool water at 30°C and boiler water at 82°C.

Technical Drawings and Spare Parts: Technical drawings and spare parts details, including dimensions and part numbers for components like "O" seals and tube stacks, are provided.

Operating Conditions: The document specifies a maximum working pressure of 6 bar and a maximum working temperature of 100°C.

Procedures: When replacing the tubestack, new seals must be fitted. Installation should be downstream of pumping and filtration equipment, with pump-assisted circulation to prevent air locks. The pool water pump should be controlled by a thermostat set to the desired pool temperature.

Standards and Recommendations: It is crucial to maintain the pool's pH level between 7.4 and 7.6, and chlorine levels should be within the recommended range. Regular checks of the filter unit are necessary to prevent erosion, and debris should be kept out of the pool.

Technical Data: A table for selecting the appropriate heat exchanger based on solar panel water temperatures and pool capacities is included, with performance based on an 8-hour cycle.

Installation and Operating Instructions: Detailed instructions are provided to prevent corrosion/erosion, including maintaining correct pH and chlorine levels and ensuring proper valve positioning in bypass circuits.

Key Components: Part numbers for components such as thermostat pocket end covers, mounting brackets, and tubestacks are listed, with specific assembly and installation instructions.

In Line Plate Heat Exchangers: These are designed as a cost-effective alternative to shell and tube types, featuring a unique internal flow arrangement for direct installation in pipework.

Stainless Steel Heat Exchangers: Suitable for harsh water environments, these exchangers handle corrosive fluids and are available in three or single pass configurations.

Thermostat Pocket End Covers: Heat exchangers can be equipped with a thermostat pocket in the inlet end cover, suitable for a 7 mm probe, eliminating the need to fit the thermostat into the pipework.

Non-Storage Calorifiers: These heat water indirectly from a low-pressure primary supply, constructed with non-ferrous materials on the secondary side.

DC Oil Coolers: Designed for small marine transmissions, these oil coolers use cupro-nickel tubes for longevity, with neoprene mouldings for easy installation and maintenance.

Marine Engine Cooling Methods: Three methods are discussed: direct cooling, heat exchanger cooling, and keel cooling, with heat exchanger cooling preferred for isolating seawater in corrosion-resistant components.

Bowman Heat Exchangers: Highlighted for their quality and technical features, such as a fully floating tube stack to minimize thermal stresses and ease of cleaning.

Installation and Maintenance: Recommendations include maintaining specific water velocities and ensuring proper installation to prevent air entry into the engine water circuit.

Product Selection and Ordering: Guidance is provided on selecting the appropriate heat exchanger and oil cooler sizes based on engine type and transmission.

Materials and Construction: Standard materials include aluminum castings, with CuNi 90/10 tubes and bronze or neoprene end caps on the sea-water side.

Swimming Pool Heat Exchangers There are two ranges of Bowman swimming pool heat exchangers, one for use with boilers and the other for use with solar panels. See pages 3-8 for heat exchangers used with boilers and pages 9-12 for heat exchangers used with solar panels. Swimming pool heat exchangers provide a simple method of heating swimming pool water indirectly from a boiler or solar panels. All Bowman swimming pool heat exchangers are manufactured with corrosion resistant cupro-nickel tubes and bronze end covers and are therefore suitable for use with chlorine water, seawater and spa pools....
