REX Tank Heat Exchangers
The new generation REX instantaneous indirect water heaters are engineered for high heating efficiency. REX heaters use the boiler to heat domestic water instantly upon demand. As the boiler water enters the tank (not the coils) it is stored, ready for a domestic water call.
REX heaters also act as a buffer tank to eliminate boiler short cycling. The boiler water is circulated in a closed loop system, thus extending boiler life.
The REX indirect instantaneous system offers high efficiency, long life and an economical way of heating domestic water as there is no stagnant water in the coils. It virtually eliminates bacterial growth.
Applications
- Domestic
- Commercial and industrial institutions (hotels, apartments, schools, hospitals)
- Excellent for close temperature approach applications
Maximum Working Pressure
- Up to 150 PSI (1.03 MPa)
Maximum Working Temperature
- Up to 375°F (190°C)
Standard Materials
- Completely passivated stainless steel construction.
The stainless steel distributor is the key to proper distribution of the boiler water over the coil tubes to give peak heat transfer as the hot water cascades through the coils, providing greater turbulence as it reaches the bottom distributor plate.
Constructed from stainless steel, the REX water heaters are built to last. All of the REX tanks are designed to be used for modular installations and all will fit through a 30 inch doorway.
The REX heaters are an efficient solution for new projects and are ideal for retrofit applications to improve existing system performance and reduce installation costs.
