Kronos Pipe Flexible Refrigeration Tubing Kit Ø 1/4" 3/8" - 6 Meter Roll

The Zimaklima Kronos Pipe 6002-6000 refrigeration pipe kit is designed to make connections between the indoor and outdoor units of air conditioning equipment and direct expansion systems. It includes 2 rolls of 6-meter pipe, one with a nominal diameter of 1/4 inch and the other 3/8 inch.

The Kronos Pipe system is a flexible alternative for refrigerant piping and stands out for its ease of handling. The pipe can adapt to different curves and angles during installation, reducing the need for shaping work such as that commonly required with rigid piping.

Flexible pipe for air conditioning installations

The main feature of the Kronos Pipe system is its flexibility. Its multilayer construction allows the pipe to be routed and bent during installation, making it easier to run between the indoor unit and the outdoor unit of the HVAC system.

This flexibility is especially useful in installations with direction changes, narrow passages, or routes where the refrigerant line must be adapted to the available space.

It is also a lightweight and easy-to-handle pipe, features that help simplify both transport and on-site installation work.

Kit with 1/4 and 3/8 inch pipes

Reference 6002-6000 consists of two refrigeration pipes of 6 meters in length each:

• 1 roll of 6 meters with a nominal diameter of 1/4 inch.
• 1 roll of 6 meters with a nominal diameter of 3/8 inch.

This combination of diameters is common in many direct expansion air conditioning systems and provides, in a single kit, the two lines needed for refrigerant circulation between the system units, provided the sizes match those specified by the HVAC manufacturer.

Compatible with R32, R410A, R134a, R404a and R407c refrigerants

The Kronos Pipe tubing is suitable for connecting direct expansion systems that work with different refrigerant gases. According to the system technical data sheet, it is compatible with:

• R32.
• R410A.
• R134a.
• R404a.
• R407c.

It can also be used for refrigerant transport in both liquid and gaseous state within the pressure and temperature conditions established for the system.

Kronos Pipe is not compatible with R22 refrigerant.

7-layer multilayer construction

The Kronos Pipe tubing uses a 7-layer structure designed to provide mechanical strength, tightness, insulation, and protection against the usual conditions of a refrigeration installation.

Its composition includes:

• Inner long-chain polyamide layer.
• Four-layer aluminum protective film.
• High-tenacity synthetic fiber braid.
• Intermediate polymer coating with a high barrier effect.
• Outer coating resistant to wear, ultraviolet rays, and abrasion.
• Closed-cell expanded polyethylene foam insulation.
• Outer protective polyethylene film resistant to ultraviolet rays.

This construction makes it possible to use the same pipe both to carry the refrigerant and to provide the necessary insulation around the refrigerant line.

Integrated insulation

The pipes included in this kit incorporate a closed-cell expanded polyethylene foam insulating cover. This layer helps limit heat exchange with the environment and helps control condensation formation in the installation.

The outer layer also provides protection against ultraviolet rays, wear, and abrasion, helping protect the pipe during installation and service.

Operating temperature and pressure

The Kronos Pipe system is designed to operate over a wide range of conditions within refrigeration circuits. Its operating temperature range is between -30 and 110 degrees Celsius, with occasional peaks of up to 130 degrees Celsius.

The technical documentation specifies operating conditions of up to 80 bar and indicates that the system has been tested at 100 bar.
