The APC ACCU301 is an air-cooled condenser unit designed for precision cooling in data centers, specifically developed for InRow-DX cooling technology. The unit provides a cooling capacity of up to 30 kW and is designed for operation with a 3-phase AC power supply of 460–480 V and a line frequency of 50/60 Hz. It is classified as a single feed system, meaning the entire electrical power is supplied through a single power connection. The unit is classified as CPNT type and serves as the outdoor unit in a closed cooling system that removes heat from the data center environment.

Applications
The ACCU301 is designed for use in professional IT infrastructures, particularly in data centers where continuous and precise temperature control is required. The condenser unit is installed outdoors and works in conjunction with the indoor cooling unit (InRow-DX) inside the data center. It is designed for environments with high thermal loads from IT systems and requires reliable cooling performance of 30 kW. The unit is not intended for use in residential spaces or small offices, but for industrial and technical applications.

Features and Specifications in Detail
The condenser unit operates using air-cooled technology, where heat from the refrigerant circuit is dissipated into the ambient air via fans and condenser surfaces. The cooling capacity of up to 30 kW enables heat removal from multiple server racks or a larger IT cluster. The unit is designed for single feed operation, simplifying installation as no additional power lines are required for the condenser unit. The operating voltage of 460–480 V is typical for industrial facilities and ensures stable power supply.

Technology Explained Simply
The ACCU301 uses air-cooled condenser technology, where the refrigerant, after evaporation in the indoor unit (InRow-DX), condenses in the outdoor unit. Heat is transferred to the ambient air through a heat exchanger, with air drawn in by fans and passed over the condenser surfaces. The 3-phase power supply ensures even load distribution and high efficiency. The line frequency of 50/60 Hz allows operation in various countries with different power grid standards. Single feed means all electrical power is supplied through a single connection, simplifying installation.

Compatibility and Accessories
The ACCU301 is specifically designed for use with InRow-DX cooling units from APC. It serves as the outdoor unit in a closed cooling system consisting of an indoor and outdoor unit. Combining it with InRow-DX indoor coolers enables precise and efficient cooling of IT systems. No specific accessories are mentioned in the sources that can be directly combined with the ACCU301. The unit is designed as a standalone outdoor unit and does not require additional components for operation.

Installation and Mounting
The ACCU301 is installed outdoors, typically on a roof, in a technical room, or in a dedicated cooling room. The unit measures 1000 mm (length) × 1000 mm (width) × 1555 mm (height) and weighs 267 kg, requiring secure mounting on a suitable foundation. Power supply is via a 3-phase AC line with 460–480 V. Connection to the indoor cooling unit (InRow-DX) is made through refrigerant lines installed during setup. No additional installation steps beyond standard procedures for condenser units are required.

Operational Advantages
The ACCU301 offers a high cooling capacity of up to 30 kW, making it suitable for larger IT loads. The air-cooled technology reduces complexity compared to water-cooled systems, as no water supply or drainage is required. Single feed simplifies electrical installation and reduces the number of required power connections. The operating voltage of 460–480 V is typical for industrial facilities and ensures stable power supply. The unit is designed for data center environments where continuous and reliable cooling is essential.

Product Status
According to sources, the APC ACCU301 has been discontinued. This means the product is no longer manufactured in series and may no longer be available. Existing stock may still be available, but no future production is planned. Customers requiring a replacement solution should consider current models from the InRow-DX series by APC.

Scope of Delivery
The scope of delivery for the APC ACCU301 includes only the condenser unit itself. No additional components such as cables, mounting materials, or tools are included. Installation requires separate mounting and connection elements, which are not part of the delivery.
