Aqua Heat- Hot Water Generator by Asiatic Traders

Aqua heat is an instantaneous tap water system designed to provide domestic hot water in large quantities - up to 1200 kW - for applications such as apartment buildings, hospitals, hotels, retirement homes, nursing homes, schools, sports centers, etc.

Different models of Aqua heat are available to fit with any installation arrangement. For instance, Aqua heat operated with a 2-port or 3-port valve can be connected to Bosch boilers on site or primary tanks. Aqua Heat operated with a 2-port valve would match requirements of district networks when the tap water system is directly connected to the Wilo Hydro pneumatic system.

When it comes to the selection of the heat exchanger, Aqua Heats offers a world class Gasket heat exchanger from Alfa Laval.

Principal

On the primary side, Aqua Heat has to be fed by a heating source that is provided by Bosch Boiler system or Bosch solar thermal panels or combination of both. (*-if heat pumps are primary source of heating please contact our technical team)

On the secondary side, Aqua Heat is connected to the wilo booster system (CW) and provides domestic hot water to the distribution pipe work when tapping occurs. A Wilo circulation pump (PR) is usually used to limit the time needed to deliver domestic hot water to the tap at the right temperature. The circulation pump maintains a minimum flow rate through the heat exchanger and through the distribution pipe work Wilo Hydro pneumatic system are used to boost the water through heat exchanger. The booster pumps are also available with variable speed drive version.

Energy is exchanged through the Alfa Laval heat exchanger from the primary to the secondary side

A temperature sensor (S) located at the secondary side outlet checks the temperature and adjusts the control valve (VA) accordingly in order to always maintain hot water at the right temperature. The piping arrangement of the control valve provides tight control of the energy entering the primary side.

On the primary side is adapted to the demand detected on the domestic side. This eliminates thermal shock in the heat exchanger and reduces the build-up of lime scale in the secondary side. The primary pump (PP) maintains a constant flow rate through the Alfa Laval heat exchanger Bosch solar thermal energy or Bosch Boilers.

In the case of aqua heat with a 2 port valve, the heating source enters the heat exchanger at the minimum available temperature and variable flow rate. The 2 port valve connected to the control equipment will ensure that the right flow rate and thus the right amount of energy is fed into the heat exchanger to always ensure constant water temperature on the secondary side.

If the water is very hard in the area where the tap water system is used, temperature control should always be fitted in order to avoid lime scale deposits and the temperature set point on the secondary side should also be limited on the basis of local experience. The aqua heat is available with control box that can detect and warm the user that scaling is occurring into the heat exchangers. Though this early warning message, the development of lime scale can be reduced as the user will be able to plan for the cleaning of the heat exchangers.

Aqua heat flow offer electronic control equipment that provides several user- definable function to customize the system and ensure precise temperature control

The plates Gaskets heat exchangers can be easily cleaned by opening the plate pack. The copper Brazed or Alfa Nova heat exchangers do not need to be opened because they provide additional connection to perform cleaning in place treatment on site.
