Project Selection for the UAE and Saudi Arabia

For projects in the UAE, Saudi Arabia or another destination, confirm the required voltage, phase, frequency and site ambient operating range before ordering. The published specifications above are for the 50Hz version. A 60Hz requirement needs a separately confirmed configuration and performance datasheet.

To request equipment selection and a quotation, share:

Application, project country and installation location.
Daily hot water volume and peak demand or recovery time.
Incoming water temperature and required delivery temperature.
Storage tank capacity, circulation arrangement and available water flow.
Site design ambient conditions and power supply voltage, phase and frequency.
Required quantity, delivery date and any required project documentation.

Unit quantity should be selected from the project load and operating conditions. Where a project requires a water temperature above the listed rating point, ask our team to confirm a suitable model and configuration.
