Product Description:

The ABS automatically maintains clean heat transfer surfaces                                                                                without interrupting normal equipment operation.

The ABS System consists of an integrally mounted 4-way                                                                                    reversing valve that permits the reversing of the direction of  water flow in the heat exchanger.

This flow reversal has been found to significantly reduce fouling in the plate and frame heat exchanger.

The flow reversal is controlled by a control panel mounted to the plate and frame heat exchanger or at a separate location as desired.

The frequency of flow reversal is set up to match job conditions. Normally, flow reversal would occur once every six to eight hours.
