ASHP External 140mm Trunking Overview

The ASHP External 140mm Trunking from DiversiTech International protects the pipework and insulation that run from an air source heat pump into the property. At 140mm wide and 90mm deep, it houses the insulated flow and return pipes plus any associated cabling in a single run. As premium ASHP trunking, it gives exposed external pipework a purpose-made, protective cover. It suits installers who want every external installation to look as finished as the unit itself.

Key Features

• Sized for insulated flow and return pipework plus cabling
• Trunking supplied in 2000mm lengths
• Made from high grade, fade resistant PVC
• Available in ivory and black
• Protection from the elements, accidental damage and pest damage
• Matching wall covers, connectors and 90° internal, flat and external bends

Installation Benefits

This ASHP trunking is designed to be easy to install, so finishing the external pipe run does not slow the job down. Matching fittings handle corners, joins and the wall entry. The result is consistent from unit to wall, with fewer site-made workarounds.

With flow, return and cabling in one enclosure, the run stays tidy and easy to inspect at commissioning and service visits. Shielding the insulation from weather and knocks also reduces the risk of callbacks caused by damaged lagging.

Benefits for Your Customers

Exposed pipe insulation looks untidy and is vulnerable to weather, accidental damage and pests. This heat pump pipe trunking covers it with a neat, professional finish, in ivory or black to blend with the building. Keeping the insulation intact helps the heat pump run efficiently, protecting the savings your customers expect.

Compatibility and System Integration

Every component shares the same 90mm by 140mm profile, so straight runs, wall covers and bends can all be specified from one range in the chosen colour. The black range adds a 45° vertical bend. Using one external pipe trunking system across jobs also simplifies ordering and keeps your installations visually consistent.

The ASHP External 140mm Trunking pairs with the Flexi Lite Slab and Foot Kit. Together they give a complete base-to-wall package for the outdoor unit and a simple add-on to every heat pump quote.
