Fluidra - Titanium Heat Exchanger for Zodiac Z400 iQ MD7 S Heat Pump

Fluidra – Titanium Heat Exchanger for Zodiac Z400 iQ MD7 S Heat Pump

This is the genuine Fluidra replacement titanium heat exchanger (condenser) for the Zodiac Z400 iQ MD7 S pool heat pump. It is the core component responsible for transferring thermal energy from the refrigerant circuit to the pool water, keeping your pool at the desired temperature efficiently and reliably. Titanium construction makes it fully resistant to the corrosive effects of chlorinated and salt-treated pool water.

Compatibility

This heat exchanger is designed as a direct OEM replacement for the Zodiac Z400 iQ MD7 S pool heat pump, part of Fluidra’s Z400 iQ residential heat pump range. The Z400 iQ series covers a wide range of residential pool volumes, with MD7 models suited to pools of approximately 50–80 m³. Always verify your unit’s model number before ordering to ensure correct fitment.

Why Genuine Matters

The Z400 iQ features a titanium water exchanger condenser as standard — a material chosen specifically for its outstanding resistance to corrosion from both salt electrolysis systems and conventional chlorine treatment. Using a genuine Fluidra part ensures the replacement exchanger meets the same material grade and dimensional tolerances as the factory-fitted unit, protecting the efficiency and longevity of your heat pump. Third-party alternatives may not match the metallurgical specification required for long-term durability in pool environments.

Installation

Replacement of a heat pump heat exchanger involves working within a refrigerant circuit and hydraulic connections, and must be carried out by a qualified pool heating or HVAC technician. Ensure the unit is fully isolated — electrically and hydraulically — before any work begins. Refer to the official Zodiac Z400 iQ service documentation for torque values, refrigerant handling procedures, and pressure test requirements.
