Flow heaters

Flow heaters are compact, closed circulators designed for applications where an open tank is unsuitable or inconvenient

Once the system has been filled, the liquid level requires no monitoring (in a closed system) and there is no risk of contamination from dust or particles in the air.

Flow heaters are widely used in conjunction with corrosion-resistant heat exchange coils for controlling the temperature of tanks containing corrosive liquid.

Circulator

for circulation through open and closed systems

Ambient + 5 to 80°C operation



Stability to ±0.004°C

Digital setting and display

Construction

temperature control unit, miniature heating
chamber and pump, all housed in an outer case, with inlet and outlet pipes at the rear


Flow Heater
FH16D Flow Heater


Design features

units are compact and designed to take up the minimum of bench space

robust, with powerful pumping so they can equally well be located beneath the bench

constructed from corrosion resistant materials particularly important if anti-freeze is to be used
