Cold aisle energy-saving manufacturer of spiral wound tubing

Politubes, Electrolock, GREMCO, and Corex are leading manufacturers of spiral-wound tubing suitable for energy-efficient insulation and protection in industrial and electrical applications.

Politubes

Politubes offers the SpiralGuard™ range, which includes spiral-wound insulating tubes made from high-performance materials such as Mylar® polyester, Nomex® aramid paper, Kapton® polyimide, and composite laminates. These tubes provide excellent thermal insulation, dielectric strength, and mechanical protection, making them suitable for applications where energy efficiency and thermal management are critical, such as in electric motors, transformers, and HVAC systems. Politubes also provides heat-shrinkable versions and multilayer systems like SHRINK-FIBER, which enhance mechanical strength and thermal resistance while maintaining low weight and flexibility. Their products comply with REACH, RoHS, UL, ISO 9001, and IATF 16949 certifications .

Electrolock

Electrolock specializes in custom-designed spiral-wound tubes using materials such as PET (polyester), Kapton® (polyimide), Nomex® (aramid paper), aluminum, fiberglass, and Pyrodox® mica. They offer cut-to-length parts, continuous rolls, flared ends, and special configurations to integrate efficiently into automated production systems. Electrolock emphasizes thermal, electrical, and mechanical performance, which can contribute to energy savings in cold aisle or thermal management applications by reducing heat loss and improving insulation efficiency .

GREMCO (FITCOTUBE®)

GREMCO produces polyester spiral-wound heat-shrink tubes using Mylar®/Nomex® laminates. These tubes provide waterproofing, electrical insulation, and strong thermal protection, suitable for securing electromagnets or insulating components in energy-sensitive environments. Their heat-shrink properties ensure a tight bond and minimal thermal leakage, which can support energy-saving goals in industrial or data center applications .

Corex

Corex manufactures spiral and parallel wound cardboard tubes primarily for industrial and packaging applications. While their focus is on mechanical strength and protection, their customizable wall thicknesses and diameters allow for potential use in thermal insulation or airflow management in cold aisle setups. Corex offers special exterior treatments and long-length tubes, which can be adapted for energy-efficient ducting or protective insulation in industrial environments .

Summary

For cold aisle energy-saving applications, Politubes and Electrolock are particularly relevant due to their high-performance insulating materials, thermal resistance, and customizable spiral-wound designs. GREMCO provides additional options for heat-shrinkable insulation, while Corex offers structural tubes that can be adapted for airflow or protective insulation. When selecting a manufacturer, consider material type, thermal performance, customization options, and certifications to ensure optimal energy efficiency and integration into your system.
