HVAC Works & Daikin VRF Integration

Space-optimized Daikin VRF networks, intelligent tenant zoning and in-house SMACNA-compliant ductwork — engineered for peak UAE summer loads.

Overview

Thermodynamic zoning, optimized for space.

In multi-storey configurations such as Basement + Ground + Mezzanine + 3 Floors + Roof, space optimization and thermodynamic zoning are paramount.

As an experienced installer of Daikin VRF technology, ETTS engineers networks that optimize structural space by placing compact Daikin Outdoor Units (ODUs) exclusively on the roof — with tailored refrigerant piping linking to multi-split indoor units mapped to individual tenant zoning profiles.

Value Delivered

Zero performance risk — optimal equipment sizing, peak efficiency under summer loads, and valid manufacturer-backed warranties.

Key Capabilities

Every element of the air-side system.

From VRF selection to fabricated ductwork and smoke management.

Daikin VRF Deployment

Compact Daikin ODUs placed exclusively on the roof, freeing valuable structural space below.
