HMX’s PCU (pre-cooling unit) combines indirect evaporative cooling and refrigerant-based cooling to cool the fresh air entering a building in the most energy efficient manner. The PCU does not rely on the building’s return air to enable pre-cooling or energy recovery, and thus saves energy, capital expenditure and operational costs when compared to other conventional fresh air-cooling systems (Dedicated Outdoor Air Systems or DOAS), treated fresh air units (TFAs) and energy recovery units (ERUs).

The HMX Dual Air Moisture Adjustment (DAMA) Enhanced Energy Efficiency (E3) Air Handling Unit (AHU) is a hybrid system that is an ideal replacement for conventional chilled-water AHUs to increase fresh air intake by up to three times current levels without an energy penalty. Traditional AHUs typically handle approximately 10-15% of their total air handling capacity as fresh air. HMX’s DAMA E3 AHU integrates indirect evaporative cooling as part of the AHU to allow the fresh air volume to be increased to 30% of the total air, without an increase in cooling coil tonnage.

HMX’s indirect-direct evaporative cooling (IDEC) system is a patented, scalable, energy-efficient, and 100% fresh air-cooling solution. IDEC utilizes the heat of evaporation of water to cool air in two stages of evaporative cooling – first indirectly, then directly. This system has been successfully deployed in India and the Middle East for cooling of high-occupancy indoor spaces where both cooling and fresh air a required for the comfort and health of the occupants.

HMX’s unique indirect evaporative cooling (IEC) technology cools without adding moisture to the supply air. As a result, it can be integrated with conventional refrigerant-based cooling to provide consistent temperature and humidity-controlled cooling for all weather conditions and regions. These “Hybridized” HMX cooling solutions save energy, capital expenditure and operating costs over conventional cooling systems. They have been successfully deployed in India and the Middle East in commercial and industrial settings.
