DCT Heat Pump Technology

Dalrada Climate Technology (DCT) Heat Pumps

DCT Industrial Heat Pumps (One and Two series) provide heating and cooling without combustion and can replace water heaters, steam boilers, chillers and cooling towers. Our revolutionary heat pumps use a non-toxic, non-flammable, environmentally friendly natural refrigerant that’s completely CFC and HFC-free.

All DCT heat pumps use carbon dioxide as the refrigerant fluid in a closed system. The heating and cooling loads are connected via secondary heat transfer fluids, usually water or glycol.

DCT core technology is a novel form of heat pump technology that employs super-critical CO₂ as the working fluid, to enable the highly efficient recovery of low grade heat from air, water, or thermal waste streams, for use in high grade heating applications.

This advance climate technology helps support the global initiative of transitioning to Net Zero through renewable and sustainable energy technology and innovation, minimizing carbon emissions and improving energy efficiency.

Heat Pump Applications
Dalrada Heat Pump System

No need for chillers, cooling towers or boilers!

DCT heat pumps provide heating and cooling without the need for water heaters, steam boilers, cooling towers or chillers. This reduces the size of plant rooms and technical spaces within buildings, meaning you can focus on maximizing space. Our pumps are sleek and compact in design.

Maintenance and Servicing

DCT heat pumps are designed to require minimal user maintenance. Other than regular level and performance checks the units should be subject to a full service shutdown at least annually with replacement of refrigerant and compressor oil, filter cleaning/replacement, relief valves testing/replacement and recommissioning.

  • Hot & Cold Coupling

    Innovative technology for use in applications that link to local heat networks, where hot and cold coupling is a necessity (IT, server cooling, district heating, and more).

  • Cost & Energy Efficient

    Savings of thousands of dollars every year and reduced carbon emissions. Up to 75% increased energy efficiency and eligible for tax credits and incentives.

  • F-Gas Exempt Refrigerant

    Non-toxic, non-flammable, and eco-friendly R744 Carbon Dioxide (CO2). This natural refrigerant is CFC and HFC free with an ODP of 0 and GWP of 1.
