Characteristics of the Simple Heat Recovery Unit

Structure

Standard Dimensions

Length × width × height
2,350 × 610 × 780 mm
This machine is made from a resin with outstanding heat and chemical resistance and thermal insulating properties. Since the robust and compact box-type construction is floor standing, installation is simple and no foundation work is required.

Heat exchanger

In this machine, a thin stainless steel pipe with an external diameter of 25mm forms the dividing boundary through a series of S-bends. Inside the machine, warm wastewater repeatedly flows over the outside of this series of S-bends, warming the clean water flowing through the pipe. The pipe consists of 12 sections and 25 lines, with a total heat transfer area of 17.7m², and is capable of processing wastewater at the rate of 8m³/h.

Advantages

Easy to maintain

Since the installation is open, it can be cleaned while in operation with a purpose-made brush. Thus, the machine can deal with even heavily contaminated wastewater.

Inexpensive

This machine has a simple construction and since it is floor standing, installation is straightforward. Return on investment can be achieved in a short period of time.

Lasting heat efficiency

While the initial heat efficiency may be slightly lower than that of other systems, the machine suffers no soiling or clogging even with heavily contaminated wastewater. This means that economical efficiency will not deteriorate and a level of exhaust-heat recovery close to or equal to that of other systems can be maintained.

Contributes to quality management

With the incorporation of this machine into continuous desizing and scouring and dyeing machines, a system for the regulation of the water supply for cleaning and of water temperature can be easily realized. This leads to great improvements in the levels of both quality management and of energy saving.
