Kronos Pipe Flexible Refrigeration Tubing Kit Ø 1/4" 1/2" - 6 Meter Roll

The Zimaklima Kronos Pipe 6003-6000 flexible refrigeration pipe kit is designed to connect the indoor and outdoor units of direct expansion air conditioning systems. The kit combines 1/4 and 1/2 inch pipes with a length of 6 meters, providing the two sizes required for many HVAC units.

Kronos Pipe stands out for its high flexibility and ease of handling. The pipe can adapt to bends and changes in direction without the need for tools to shape it, making installation especially easy in complex routes, tight spaces, or installations with multiple changes in direction.

Kronos Pipe 1/4 and 1/2 inch kit for air conditioning

Reference 6003-6000 belongs to the Kronos Pipe system developed by Zimaklima for refrigeration and HVAC installations. The set is made up of 1/4 and 1/2 inch sizes, with a length of 6 meters, to create the refrigerant lines between the unit components.

Before installation, it is necessary to check that the 1/4 and 1/2 inch diameters match the connections and specifications indicated by the air conditioning manufacturer.

Flexible pipe for easier installation

One of the main advantages of the Kronos Pipe system is its ability to adapt to different curves and angles. Its flexible construction allows the pipe to be positioned during assembly without using specific tools to make each bend.

This feature simplifies the routing of refrigerant lines and is especially useful when the run must overcome obstacles, pass through narrow spaces, or adapt to the building geometry.

In addition to being flexible, Kronos Pipe has a reduced weight that makes it easier to handle and transport during installation work.

Compatible with R32 and R410A refrigerants

According to Zimaklima's technical data sheet, Kronos Pipe is designed to work in direct expansion systems that use various common refrigerants in air conditioning and refrigeration installations.

The system is compatible with:

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

The technical documentation expressly states that Kronos Pipe is not compatible with R22 refrigerant.

7-layer multilayer construction

Kronos Pipe uses a 7-layer multilayer structure, developed to provide sealing, mechanical strength, external protection, and thermal insulation in refrigeration applications.

The structure indicated by Zimaklima is made up of:

• Long-chain polyamide on the inner side.
• Four-layer aluminum protective film.
• High-tenacity synthetic fiber braid.
• Intermediate polymer layer with a high barrier effect.
• Outer layer resistant to wear, ultraviolet rays, abrasion, and chemical agents.
• Closed-cell expanded polyethylene foam insulation.
• Outer polyethylene film with UV protection.

This construction makes it possible to combine refrigerant flow, the necessary circuit strength, and external line insulation in a single product.

Built-in thermal insulation

Kronos Pipe tubes feature a closed-cell expanded polyethylene foam insulating cover. This insulation limits heat exchange between the refrigerant and the environment and helps control condensation on the surface of the refrigeration line.

The outer protection also offers resistance to ultraviolet rays, wear, and abrasion, helping preserve the pipe during handling, installation, and operation.

Operating range from -30 to 110 degrees Celsius

The system is designed to operate at temperatures between -30 and 110 degrees Celsius. The technical data sheet also specifies resistance to peak temperatures of up to 130 degrees Celsius on a temporary basis.

In terms of pressure, Zimaklima specifies operating conditions between 0 and 80 bar. The pipe has also been tested at a pressure of 100 bar.

• Minimum bending radius: 130 millimeters.
• Approximate weight: 147 grams per meter.

Tested for refrigeration circuits

The Kronos Pipe system is specifically developed for refrigerant flow and has undergone different laboratory tests. The technical data sheet states EN 1736:2008 as the reference standard, applicable to flexible pipe components used in refrigeration systems and heat pumps.

Its use is intended both for the connection between indoor and outdoor units of direct expansion equipment and for transporting refrigerant in liquid or gaseous state within the specified operating conditions.
