High efficiency cooling interface units (CIUs) for properties that suffer overheating due to solar gain or any other reason.  The CIU is connected to a centralised chilled water system and exchanges cold water to the apartment cooling system on demand.

The most efficient heat interface units in the UK

HIU performance has a major impact on the operating efficiency of a heat network. The same goes for CIU performance.

Pioneering HIU design

Heatweb manufactured the very first electronic HIUs in the 90s. We continue to drive the industry forward through continuous product development and many unique, patent-protected features.

We have unmatched experience and understanding of heat network design, based upon many thousands of successful installations throughout the UK, and can provide more accurate and efficient utilisation of thermal energy in district heating environments.

The DIGI Cool S-Line

Single plate CIU with electronic control, integral pump, expansion vessel, pressure independent control valve, cooling energy meter and top pipework connections.

DIGI-Cool is simple but efficient due to the continuously adjustable, pressure-independent primary flow rate which dictates the primary energy input.

  • 3, 6 & 12kW Indirect cooling output

The DIGI Cool M-Line

Single plate CIU with electronic control, integral pump, expansion vessel, pressure independent control valve, cooling energy meter and bottom primary / top secondary pipework connections.

DIGI-Cool is simple but efficient due to the continuously adjustable, pressure-independent primary flow rate which dictates the primary energy input.

  • 20kW Indirect cooling output

Cooling Substations

Need something bigger?

We also do Cooling Substations; advanced single or multiple plate substation technology designed to the same standards as our industry leading HIUs, but with a wealth of additional functionality for cooling networks, from 20kW upwards.
