It is suitable for both outdoor and indoor pools and hot tubs. The special plate design ensures high heating performance in a compact size and high efficiency for rapid pool heating. The heat exchangers achieve a temperature increase of up to 15°C between the inlet and outlet of the exchanger.
The exchanger is connected with an external ¾" thread for both the heating water and pool water. OVBD exchangers must be connected to the pool circuit via a bypass. This is due to the smaller connection openings. On the other hand, the smaller openings slow the water flow, which gives the exchanger higher performance.
The exchanger plates have special profiling that ensures a slower flow of the heating water, thereby increasing the exchanger’s performance.
The plates are pressed from corrosion-resistant AISI 316 stainless steel. The individual plates are vacuum-brazed with copper and nickel. The OVBD exchanger is a compact, non-dismantlable unit.
OVBD plate heat exchangers must be installed in a vertical position. Any other position prevents sufficient water flow and proper heat transfer. The exchanger connection threads must not be subjected to any excessive pressure. If the supply piping is long and could place stress on the threads, the pipes must be supported.
Install the exchanger on a base plate or on the wall using brackets (not included). Smaller exchangers with fewer than 30 plates can be mounted directly on the pipes. For a specific installation, local conditions must be taken into account.
