SONDEX / Danfoss – Technical profile of a heat exchanger manufacturer

SONDEX is a Danfoss product brand for heat exchangers. The range includes gasketed, brazed, semi-welded, welded, spiral, plate-and-shell, evaporator and microchannel heat exchangers for HVAC, district energy, refrigeration and industrial process applications.

The product range represented through Philippopoulos S.A. includes:

• standard gasketed plate heat exchangers,
• Free Flow plate heat exchangers,
• sanitary / hygienic plate heat exchangers,
• brazed plate heat exchangers,
• semi-welded heat exchangers for ammonia,
• plate-and-shell heat exchangers,
• spiral heat exchangers,
• evaporators,
• microchannel heat exchangers.

Gasketed plate heat exchangers are used for heating, cooling and heat recovery. They allow access to the plate pack for inspection, cleaning, gasket replacement and possible capacity expansion by adding plates.

Free Flow heat exchangers are used for liquids with fibres, particles, solids, high viscosity or fouling tendency. Their wider channels reduce clogging compared with standard plate patterns.

Sanitary heat exchangers are used in food, beverage, dairy and pharmaceutical duties. Selection must consider cleanability, CIP, drainability, gasket material, product compatibility and hygienic documentation.

Brazed plate heat exchangers are compact and gasket-free. They are used in HVAC, heat pumps, chillers, substations and closed-loop cooling systems. Since they cannot be mechanically opened, fouling risk and chemical cleaning must be considered.

Semi-welded plate heat exchangers are used in ammonia refrigeration, condensers, evaporators, subcoolers and oil coolers. Plate-and-shell and spiral heat exchangers are used for higher pressure, higher temperature, condensation, slurries or fouling fluids.

Heat exchanger selection must be based on thermal duty, flow rates, inlet and outlet temperatures, pressure drop, design pressure, design temperature, material compatibility, fouling factor and service access.
