Cooling water circuit regulation
The open cooling-water circuit must be connected to a potable
water outlet (requirements: see Installing the water system and
cooling panel on page 48). The circulation pump transports at
least 6 m³/h (1585 gal US/h) through the probe cooling jacket.
The resistance thermometer is installed in the cooling water
tank and signals to the water temperature controller.
The water flows through the heat exchanger where a fan is
operated to control the required cooling of the water based on
the water tank temperature. The flow rate is monitored as the
water returns from the probe in order to validate the actual flow
which has been cooling the probe. Monitoring is performed on
the HMI on the control cabinet.
Requirements for the water supply
The water supply must meet the following minimum
requirements:
Category Requirement
Consumption 0 to 2 m³/year (0 to 528.35 gal US/year)
Quality Potable water (do not use anti-corrosive), do not use
demineralized water
Ambient temp. • Glycol as anti-freeze. Anti-freeze with anti-corrosive
below 0 °C (32 °F) additive is not permitted.
• Option for water tank heater
