PRODUCT OVERVIEW
The Cooperheat Cooper36 Heat Treatment Unit is an innovative multi-channel heat treatment system designed to efficiently process up to 36 small tubes and pipes simultaneously. Engineered using Cooperheat’s extensive industry expertise, the Cooper36 provides precise individual control for each heater output, making it ideal for heat treating small diameter welds ranging from 1” to 5”. By combining high channel capacity with optimized power consumption, this unit significantly improves productivity, safety, and cost efficiency in industrial pipe and tubing heat treatment applications.
Product description
The Cooperheat Cooper36 Heat Treatment Unit is purpose-built to address the challenges of heat treating large volumes of small diameter pipes and tubes in industrial environments. Specifically designed to control up to 36 heaters independently, the unit enables simultaneous heat treatment of up to 36 pipe welds ranging from 1” to 5” in diameter, delivering precise temperature control and consistent thermal performance across all channels.
Traditionally, such applications required multiple standard 6-channel heat treatment units, often tying up as much as 300kW of machine output power. The Cooper36 transforms this process by achieving the same task using a single machine with 36 control channels and only 50kW output power. This substantial reduction in power consumption leads to significant cost savings and improved operational efficiency.
In addition to increased productivity, the Cooper36 enhances workplace safety by operating with 30V heaters rather than conventional 60V heaters, reducing electrical risk during operation. The unit also minimizes setup time and material requirements, as feed and return cables only need to supply 45A, allowing for lighter, more cost-effective cabling.
By consolidating multiple units into a single compact solution, the Cooper36 reduces transportation needs, lowers electrical losses, and decreases overall environmental impact. Combining performance, efficiency, and safety, the Cooperheat Cooper36 Heat Treatment Unit is an advanced solution for high-volume small pipe weld heat treatment in demanding industrial applications.

Frequently asked questions
What is the Cooperheat Cooper36 Heat Treatment Unit used for?
The Cooperheat Cooper36 Heat Treatment Unit is used for simultaneous heat treatment of up to 36 small tubes and pipe welds, typically ranging from 1” to 5” in diameter. It provides precise individual heater control, making it ideal for high-volume industrial pipe and tubing heat treatment applications.
How does the Cooper36 improve efficiency compared to traditional heat treatment units?
Traditional setups require multiple 6-channel heat treatment units consuming up to 300kW of power. The Cooper36 replaces these with a single 36-channel unit that can heat treat the same number of pipes using only 50kW output power, significantly reducing energy consumption, equipment usage, and operational costs.
What safety advantages does the Cooperheat Cooper36 offer?
The Cooper36 enhances safety by operating with 30V heaters instead of standard 60V heaters, reducing electrical risk during heat treatment operations. This lower voltage design helps create a safer working environment while maintaining effective heating performance.
How does the Cooper36 reduce setup time and environmental impact?
The Cooper36 reduces setup time by using a single unit instead of multiple machines and requires lighter, lower-cost cables rated at 45A. Additionally, fewer units mean reduced transportation needs and lower electrical losses, resulting in decreased environmental impact and improved overall efficiency.
