Andrews Air Conditioning is proud to introduce the ET25 HP – the latest addition to our exhaust tube air conditioner range and a high-performance portable heat pump that delivers powerful cooling and heating in a single, robust unit. Built for the rigours of industrial and commercial environments, the ET25 HP is the versatile climate control solution your business has been waiting for.

What is the ET25 HP?

The ET25 HP is a mono block portable air conditioner for hire and a heat pump designed with practicality at its core. With 7.1 kW of cooling capacity and 6.5 kW of heating capacity, it gives you year-round temperature control in spaces of up to 162 m³, whether you need to cool a server room in summer or warm a workshop in winter.

What sets the ET25 HP apart from other portable industrial units is its multi-zone capability. Its unique design allows targeted climate control in more than one area at a time, and its exhaust duct can reach up to eight metres away from the exit source, making it ideal for hard-to-reach spaces that conventional units simply cannot serve.

Where Can the ET25 HP Be Used?

The ET25 HP is a versatile unit suited to a wide range of commercial and industrial applications, including:

  • Large offices and meeting rooms – Maintain a comfortable, productive working environment throughout the year
  • Server rooms and IT suites – Protect sensitive equipment from temperature extremes with reliable, consistent cooling
  • Laboratories – Ensure precise temperature conditions for testing and research
  • Workshops and medium-sized industrial spaces – Keep staff comfortable and productive, even in demanding environments
  • Marquees and temporary structures – Ideal for events requiring climate control without permanent installation
  • Kitchens and hospitality environments – Combat heat build-up in busy, high-temperature workspaces

A Portable Heat Pump That Goes Where Others Can’t

Many portable air conditioners can cool a space, but far fewer can also heat it, target multiple zones, and duct cooling or warming to areas that are genuinely difficult to reach.

The ET25 HP does all three.

Its robust, industrial-grade build means it can withstand the demands of busy commercial environments, while its wheeled, mobile design means it can be repositioned quickly as your needs change. For businesses that need flexible climate control without committing to permanent infrastructure, the ET25 HP offers a compelling alternative.
