Experience the benefit of a heat transfer solution that perfectly matches your requirements and lowers your energy consumption.
High performance and a low pressure drop eliminate unnecessary burdens on your system and optimize overall system performance.
The design results in a compact solution with a small footprint, simple installation, and easy access for maintenance.
Gentle treatment and even distribution of the media provide the highest possible product output quality.
High heat transfer efficiency and extended intervals between cleaning ensure operation for an entire campaign with minimum downtime and maximum value for money.
Large plate gap designed to counteract fouling with sizeable plate channels and no stagnant zones.
High efficiency means that fewer plates are needed for high performance and consequently lowers the hold-up volume. Fewer plates also lowers the cost of each heat exchanger, as an added bonus.
Engineered to use smaller amounts of potentially hazardous media, the SONDEX® semi-welded range is a safe and responsible choice for demanding duties.
