  • insulation e.tc

can be adjusted to the special needs of each customer, especially Industries and big Public Buildings.


ARTEMIS stands for quality, long life and reliability.


Special features

  • Pressures up to 10 bar ensure that the boiler is suitable for big installations
  • The internal tank (DHW) acts also as a large thermal store
  • The internal tank is surrounded by primary hot water to almost all its length
  • Large heat transfer surface enables a high volume of DHW to be heated in a short time
  • Cathode protection through Magnesium Anode is available upon request.
  • Can be supplied either horizontal or vertical, depending on the special specifications of the place of installation

Insulation

Low heat losses through high density mineral wool protected by :

  • Hot galvanized metal sheets, coloured in blue
  • Aluminium metal sheets
  • Stainless steel metal sheets

Depending on the customer’s needs and the particularities of each installation can be either insulated or not.


Useful Tips for Installation & Operation

When filling the heater with water beware that you first fill the internal cylinder (DHW) and then the external (Primary Heating Water)

  • Fit a safety valve below the inner tanks maximum working pressure
  • Fit a non-return valve to DHW cold inlet
  • Don’t forget to install an expansion vessel to the primary heating circuit (return)
  • Don’t forget to connect the inner tank to the earth.
  • Hot water should not be stored at temperatures below 60 °C, to avoid the risk of Legionella.

ARTEMIS has made a simple electronic panel that provides protection against Legionella. The temperature of the sanitary water rises periodically at 75 °C for 10 minutes. Then the system returns to the initial situation.
