Thermal Cycling Tester for Plastic Piping Systems (Hot & Cold)

Introduction to Thermal Cycling Test (for Piping Systems)

In building plumbing systems (such as underfloor heating or radiators), pipes and fittings are constantly exposed to the flow of hot water followed immediately by cold water. These repeated contractions and expansions can lead to leakage at the connection points. The Thermal Cycling Testing Machine manufactured by Polymer Test simulates thousands of temperature cycles under high pressure, guaranteeing that your product has passed the ultimate durability test before installation in a building.

Hydraulic and Thermal System Features

The accuracy of this test depends on the simultaneous control of “Temperature,” “Pressure,” and water “Flow Rate.” The engineering features of the device include:

• Dual Tank System: Features separate storage tanks for cold and hot water, which significantly increases the speed of temperature switching.
• High-Pressure Pumps: Equipped with multi-stage all-stainless steel pumps capable of applying pressures up to 15 bar (with 0.1 bar precision).
• Flow Rate Control: Capability to adjust the water flow rate passing through the pipe from 10 to 40 liters per minute to simulate real-world flow conditions.

Smart Control and Wireless Monitoring

This machine belongs to the new generation of smart laboratory equipment:

• Wireless Temperature Transmission: Temperature sensors transmit tank data wirelessly to the central panel, eliminating messy cabling and improving measurement accuracy.
• Internal Logger & Network Connection: Stores all cycle data on internal memory with accessibility via LAN and Wi-Fi ports for analysis on a computer.

Applications and Related Equipment

This machine is typically used for testing Multilayer Pipes (PEX-Al-PEX) and press/compression fittings. For performing constant pressure tests (without temperature changes), you can use our Hydrostatic Pressure Tester.

Reference Standards

This device is capable of executing tests according to the following standards:

• Standard ISO 10508 (Plastics piping systems for hot and cold water installations).
• Standard ASTM F1281 (Crosslinked Polyethylene/Aluminum/Crosslinked Polyethylene (PEX-AL-PEX) Pressure Pipe).
