Heat exchanger stainless steel 316 male thread BDW16DWHx40 - 7008066

Heat exchanger stainless steel 316 male thread BDW16DWHx40

Rated for 40 litres per minute on both the primary and secondary circuits and a maximum working pressure of 16 bar on each side, the BDW16DWHx40 is built for demanding pool and spa heating installations where both flow capacity and pressure integrity are non-negotiable. The 1¼” male thread secondary connection suits standard European pipework, and the compact 377 × 329 × 118 mm envelope makes it straightforward to fit into existing plant rooms alongside a boiler, solar loop, or heat pump.

Material & corrosion resistance

Fabricated entirely from grade 316 stainless steel — the molybdenum-alloyed variant that offers superior resistance to chloride attack compared with standard 304 — this heat exchanger is well suited to chlorinated pool water circuits. The all-steel construction eliminates the copper-brazing typically found in lower-cost plate exchangers, making it the appropriate choice where pool chemistry rules out copper contact.

Hydraulic performance & circuit symmetry

With matched flow and pressure ratings of 40 ltr/min and 16 bar on both the primary (heating) and secondary (pool water) sides, the unit supports a balanced, symmetrical hydraulic design. This simplifies pump selection and pipework sizing, and the high 16 bar pressure ceiling accommodates connection to pressurised boiler circuits or district heating networks without requiring additional pressure-reducing stations.

Installation und Anschluss

The male thread connections on the secondary system allow direct engagement with standard female BSP or metric fittings common in European pool plant rooms, keeping installation clean and minimising the number of additional adaptors required. At 377 mm in overall length, the unit can be bracket-mounted horizontally or vertically to suit the available space, and the clearly separated primary and secondary ports prevent cross-circuit plumbing errors during commissioning.
