Flow Through Heaters consist of a channel brazed to the surface of a high power, thick film heater. Liquid is pumped through the channel, taking it quickly across the full element surface, optimising the energy transfer. This provides instantaneous, precise and efficient, liquid heating.
Our Flow through heaters can deliver boiling water, steam or super heated steam.
Being so fast, there is no need for standby time or warm up time, like with a thermal block, so improving energy efficiency of your application.
Features and Benefits
Instant Hot Water
Water is heated precisely to the requested temperature in mere moments! Maybe 100°C, 93°C, 60°C. Its up to you.
Elimination of warm up time or standby heating offers significant energy savings over the life of the appliance.
Responsive temperature selection
Dispensed water temperature can be set to different levels for each cup, even when the cups are filled in quick succession.
Using the EFAST feature, instant steam and even super heated steam can be generated in a controlled manner.
Electronic volume measurement
As the heater is efficient, the software can accurately calculate the volume dispensed from the power in and the temperature rise.
Flow through heaters offer significant space savings vs thermal blocks, as they run relatively cool so take up less space to install.
Flow Through Heater 2
FTH 2 is an ultra fast, high pressure, flow through heater based on a thick film heating element.
Water runs at high speed along a channel over the heater surface. This optimises the heat transfer, resulting in hot water in just seconds. FTH 2 delivers water up to boiling temperature and can also create steam! The heater will vastly improve the sustainability of your application.
Flow Through Heater 4
FTH 4 is the most compact & simple version of the flow through heater range.
Ultra fast and efficient, delivering water from cold to boiling in seconds.
The FTH 4 provides a more economical way to improve the sustainability of your application.
Flow Through Heater XL
The FTH XL is the scaled up version of the FTH Ⅱ with a maximum power of 3400W.
The FTH XL is able to handle high flow rates with a low back pressure since its channel size is twice as large as the FTH Ⅱ. This results in a good flow of hot water in seconds. Energy efficiency is key because you just heat what you need!.
|Max Power||Flow Rate @ 95°C||Dimensions||Steam
|FTH 2||2.3kW||7 ml/s||90mm||YES|
|FTH 4||1.5kW||5 ml/s||84 x 84mm||NO|
FTH construction includes:
Max operating pressure 20Bar
NTC water sensing & thermal safety protection
Our Flow Through Heaters combine a Thick Film element with a channel plate to circulate liquid over the element surface.
This robust construction allows for high pressures. An NTC at the water outlet measures the temperature, and is used to control the power or the pump.
The channel plate is joined to the steel element substrate, which gives it strength to cope with high pressure (maximum 20 bar operating, min 40 bar burst).
The stainless steel construction meets food safety standards.
Our standard Flow Through Heaters incorporate EFAST technology for overheat protection, and an outlet NTC for temperature sensing & control.
The NTC is passed through the channel plate to directly measure the temperature of the liquid.
High pressure construction combined with EFAST allows for our Flow Through Heaters to also produce steam, even super heated.
Environmental & Efficiency Benefits
Our Flow Through Heaters offer significant environmental and efficiency benefits, drawing from the core attributes of Thick Film Technology.
By reducing element mass, and eliminating standby operation, wasted energy is cut to an absolute minimum. In addition, the entire lifecycle of the product, including its manufacture, is more environmentally friendly than competing options.
With the flow through heater, there is no waiting for the heater to warm up or necessity to keep the heater hot in “standby mode”. There is no need to have a boiler full of hot water. The flow through heater instantaneously heats just the water that is required, giving significant saving energy and makes the appliance highly efficient/green.
