Malta Printing Factory HVAC Project – 45 Heat-Recovery Air Handling Units

Project Overview

Holtop delivered a complete industrial HVAC solution for a state-of-the-art printing security-products manufacturing base in Malta. Spanning roughly 29,000 m² across three construction phases, the project required precise temperature and humidity control to protect sensitive printing processes while meeting modern energy-saving standards. As an experienced heat recovery air handling unit manufacturer, Holtop supplied a fully integrated, energy-efficient ventilation system tailored to the factory's demanding production environment.

The HVAC Solution

Holtop engineered and supplied 45 sets of air handling units, combining heat-recovery AHUs and ceiling-mounted (suspended) air handling units fitted with high-efficiency EC fans for lower energy consumption. Special production areas were regulated through PLC-based control, giving the client accurate, zone-by-zone command over temperature and humidity. The three-phase rollout scaled from 50,000 CMH heat recovery units (HRU) to a full complement of 50,000 CMH AHUs and 10,000 CMH suspended units.

Why It Matters for Printing Facilities

Printing security products demand stable indoor conditions — fluctuations in temperature or humidity affect ink, paper and print quality. Holtop's heat-recovery air handling units recover energy from exhaust air, cutting operating costs while maintaining the clean, conditioned fresh air a modern printing factory needs. This makes Holtop a proven partner for large-scale industrial HVAC projects across Europe.
