MAC™
Military Designed
HVAC/ECU Products

Specific Systems MAC™ series sets the standard in the military market with quality modular environmental control systems. The lightweight modular design allows exceptional efficiency, as well as flexibility of unit configuration. Lightweight aluminum subassemblies can be easily handled and serviced. The ease of subassembly (module) replacement with the spare module results in virtually zero down time. The modular concept requires fewer spare parts for support of a given mission because the same modules and components used in different configurations of a model are interchangeable. All units feature a hot gas bypass system to prevent evaporator coil icing during low load conditions. This ensures exacting temperature control in the shelter environment for the necessary protection of electronic and computer equipment. MAC series units are available in horizontal, vertical, and slim line configuration.

Note: NSN numbers are available for many models.

MAC 61

The MAC 61 unit offers optimum performance under high sensible conditions typical of today’s modern, highly integrated shelter systems. The lightweight modular design is considerably more efficient and flexible than the standard military horizontal and vertical air conditioners. In the vertical configuration, the MAC 61 series is often installed on the back of the shelter beside the door due to its small 17” width.

MAC 61 models available:
MAC -61-06  7,800 BTUH
MAC -61-09  11,700 BTUH
MAC -61-12  14,800 BTUH

 

MAC 62

The MAC 62 offers greater capacity at a significantly reduced weight and power consumption than the standard family 18,000 BTUH horizontal units do. The unit is often applied in the slim line configuration, which offers minimal overhang in the popular over the cab application.

MAC 62 models available:
MAC-62-18  17,550 BTUH
MAC-62-24  20,650 BTUH

 

MAC 63

The flexible modular design of the MAC 63 unit makes it the perfect choice for many applications. Sturdy construction and state-of-the –art design ensures reliable long-term performance. The lightweight unit features dual compressor/refrigeration circuits to ensure 50% backup should one refrigeration system fail.

MAC 63 models available:
MAC-63-30  36,000 BTUH
MAC-63-36  46,200 BTUH

 

MAC 65

The dual compressor MAC 65 units are designed to operate from –50º F to 125º F. All MAC series military units are built to withstand extreme environmental conditions, ranging from those found in the Arabian Desert to the Antarctic. The unit’s high capacity is coupled with a lightweight interchange design, making the MAC 65 the logical choice in applications where size and weight requirements are a prime concern.

MAC 65 models available:
MAC-65-48  51,000 BTUH
MAC-65-60  66,000 BTUH

 

MAC 610

The MAC 610 is Specific Systems highest capacity military model. As featured in all MAC units, the MAC 610 has a unique flooded condenser, low ambient control design that allows the unit to start and operate at very low load and low ambient conditions (down to –50º F). The small size and accessible design of the MAC 610 allows two units (main and backup) to be mounted side by side in the end of a standard ISO Shelter.

MAC 610 models available:
MAC-610-90  90,000 BTUH
MAC-610-120  120,000 BTUH

 

MAC 61 SPB

The MAC 61 SPB, 14,800 BTUH, is designed for use in the new standardized integrated command post shelter system, designed for the hummer vehicle. The modular military air-conditioning system features the same basic design concepts as the standard specific systems MAC 61 unit but is configured to mount in a tunnel at the front of the shelter. This unit can be provided with an ultra quiet low electrical power diesel fuel fired heater.
