The key features of the Danfoss Cooling Interface Units include:
- Suitable for small one bed apartments up to major commercial applications that require a hydraulic break
- For direct cooling systems (no hydraulic break), the SAV Monolink is used to allow for flushing, flow limiting, energy measurement and credit management and billing if required
- Comprehensive quality assurance and built to standards that adhere to ISO/TS 16949:2009 (Quality management system requirements for the design and development, production and, when relevant, installation and service of automotive-related products)
- Designed to consistently achieve low return temperatures under all operating conditions, demonstrating expert control of pressure, flowrate, heat transfer and temperature
- Easy to install, commission and service, requiring no specialized equipment to set-up and begin delivering heat efficiently and reliably to the consumer
- Supported from the initial brief and employers' requirements (ER), to detailed design, commissioning, and handover, to ongoing operation and site support.

The main difference between the Danfoss 4 Series Monolinks and the 4 Series Cooling Interface Units is that the Monolinks are for direct cooling systems (with no hydraulic break), while the Cooling Interface Units are for indirect cooling systems (that require a hydraulic break).

The Monolinks are used to allow for flushing, flow limiting, energy measurement and credit management and billing if required in direct cooling systems. In contrast, the Cooling Interface Units are suitable for a wider range of applications, from small one bed apartments up to major commercial projects that need a hydraulic break.

The most important design objective for the Danfoss Cooling Interface Units is to consistently achieve low return temperatures under all operating conditions. To accomplish this, the heat interface units (HIUs) must demonstrate expert control of four key competencies that Danfoss regard as their "DNA":

1. Pressure control
2. Flowrate control
3. Heat transfer
4. Temperature control

By mastering these four areas, the Danfoss Cooling Interface Units are able to deliver efficient and reliable cooling to consumers.

The Danfoss Cooling Interface Units are designed to be easy to install, commission and service. They require no specialized equipment to set-up and begin delivering cooling efficiently and reliably to the consumer.

From the initial brief and employers' requirements (ER), through to detailed design, commissioning, handover, and ongoing operation and site support, Danfoss provides comprehensive assistance to make the process as straightforward as possible for the user.

The Danfoss Cooling Interface Units go through comprehensive quality assurance and are built to standards that adhere to ISO/TS 16949:2009. This is the quality management system requirements for the design and development, production and, when relevant, installation and service of automotive-related products.

By manufacturing the Cooling Interface Units to this stringent standard, Danfoss ensures they are of the highest quality and built to last, standing the test of time in applications ranging from small residential to major commercial projects.
