What is the AquaHeater Plus P?

What it does

The AquaHeater Plus P filters process water inline and (re)heats it as needed in specific moments of your wash process. Ideal for use in conjunction with continuous tunnel washers, it will first filter your  process water before immediately (re)heating it for re-use.  It can serve a number of points of use (depending on capacity) and you determine the default settings. A gas-fired unit, the AquaHeater Plus P’s compact size allows positioning close to point(s) of use. This has the big benefit of dramatically reducing heat losses and giving you a flexible, decentral system.

Performance boost

Its compact size allows you to place an AquaHeater Plus P in even the smallest space. Your process water can now be filtered inline, exactly when required. Furthermore, the filtrate is then (re)heated efficiently and inexpensively whenever needed. Ongoing high costs associated with  steam generation and distribution are a thing of the past.  Should demand increase significantly, then an extra AquaHeater Plus P is easily added to expand capacity. All these features add up to a performance boost with greatly increased flexibility and lower costs. Steam free offers large benefits for a modest investment.

How it works

The heart of the AquaHeater Plus P is state-of-the-art Dutch gas burner technology. The burner modulates automatically as demand fluctuates, so that the gas used at any given moment is only exactly as much as needed. No extra heat is wasted. The heater’s condensing technology yields efficiency levels of 99% (gas use) compared to levels of just 50% to 80% in traditional steam boilers. This condensing technology has been used in the Netherlands for a number of decades, the AquaHeater Plus P puts the very best of this know-how to work in an adaptation specifically for textile laundries.  A graphic display shows operators exactly what is happening, real time. The AquaHeater Plus P allows you to get the maximum out of precious ressources like water and fuel. Easy CO2 savings to boot.

The AquaHeater Plus P is carefully designed to be ‘plug-and-play’, for quick, easy installation and minimum fuss.
