Selection notes
HMU cooling and heating capacities are maximum hydro module ratings, not nominal air-conditioning capacities. Select the module with the required water temperatures and flow rate.
Allow the additional height required by the pipe outlet beyond the body height. Check the installation and service space against the complete dimensions.
Water inlet and outlet temperature limits depend on outdoor temperature and mixed operation with air-to-air indoor units. Confirm the operating envelope for the selected system arrangement.

BEFORE SELECTION
Your questions, answered.
Is HMU280KXZE1 suitable for my project?
We assess required water temperatures, flow, the hydraulic circuit and building load alongside the outdoor-unit conditions. Maximum hydro module capacity alone does not confirm a selection.
Does the proposal include installation?
We define the selected equipment, controls, accessories and installation scope after the site survey and technical selection. Share your plan with SCA for a project-specific proposal.
