Prefab Utility Cupboards for Heat Networks

With communal heating in apartments on the rise, many developers are choosing to install prefabricated utility cupboards to reduce cost and risk. This also allows them to deliver projects ahead of schedule.

Our utility cupboards are supplied fully fitted, pre-tested and ready to install on-site.

Typically, they include –

  • Heat Interface Unit

  • Cooling Interface Unit (Optional)

  • Mechanical Ventilation and Heat Recovery unit

  • Water Meter Assembly

  • All associated piping and electricals

Essco cupboards are built bespoke to project design requirements.

Packaged Plant Rooms and Skids

Reduce onsite labour costs and simplify installation with our bespoke packaged plant.

Equipment ranges from skid mounted buffer tanks or simple heat transfer packages to complete plant rooms with BMS control.

From initial design and specification to finished product on site, we can provide a solution no matter how big or small.
