Page 121: Planning The Cooling System
Install a bleeding valve at the highest point of the cooling circuit. Bleeding valve is not included in the ABB converter delivery as standard. It can be ordered as an option (+G422). The materials used in the cooling system are listed in section Specifications (page 125). -
Page 122: Mechanical Installation
122 Cooling and heating Mechanical installation Connecting the internal cooling circuit to a customer cooling unit ￭ The converter delivery does not include the liquid cooling unit that is to be connected to the converter cabinet. Connecting the liquid pipes Note: It is recommended to use closing valves in the pipe connections of the cooling circuit. -
Page 123: Converters With A Customer Cooling Unit
The most practical location for the valve is usually near or at the cooling unit. Bleeding and draining valves are not included in the standard delivery of the ABB converter. The bleeding valve is option +G422. -
Page 124: Draining The Internal Cooling Circuit
124 Cooling and heating Draining the internal cooling circuit You can drain the internal cooling circuit through the cooling unit as follows: Note: Draining coolant into the sewer system is not allowed. WARNING! High-pressure hot coolant may be present in the internal cooling circuit. No work on the cooling circuit is allowed until the pressure is lowered down by stopping the pumps and draining coolant. -
Page 125: Specifications
(RH) and the ambient temperature To avoid all kind of condensation inside the converter: ABB highly recommends to maintain / heat up the cooling liquid +10 °C (+50 °F) above the ambient temperature (ie, air temperature outside the converter), within the limits that the cooling liquid minimum temperature is +5 °C (41 °F) and maximum temperature is +60 °C (140 °F). -
Page 126: Pressure Limits
Maximum design pressure: 500 kPa Recommended design maximum pressure: 380 kPa. Note: Contact ABB if you need to rise the pressure over this limit. The pressure difference must be within given limits to avoid malfunction due to excessive coolant flow. -
Page 127: Coolant Mixture Quality
This may build up sediment in the liquid. Approved coolants • BASF Glysantin® G30® or Valvoline Zerex G30®. For other coolants, contact your local ABB representative. WARNING! Do not mix different approved coolants in any conditions! Replace the cooling liquid always with same cooling liquid! Mixing different coolant types is a risk for cooling system corrosion. -
