Designed specifically to be mounted externally on military shelters transported by ‘high mobility’ vehicles the MPA-540 is a ‘ruggedised’
air conditioning unit currently in-service with the UK MoD and other forces around the world. Providing a constant flow of filtered ‘fresh-air’ into the shelter it can be closed off if required when the shelter is unmanned, whereupon air is conditioned/cooled and recirculated.
Monitoring and display of internal shelter temperature, mode status and fault alarms, is by a separate control unit which also allows the
ACU to be operated in ‘AUTO’ mode via an electronic thermostat or ‘Heat’ or Cooling’ modes can be selected manually.
The control unit can be mounted within a 19” rack system, or as customer requirements. It is designed and tested to operate in demanding ambient temperature conditions, as defined in DEF STAN 00-35 climatic categories A1 to C0.


Constructed from stainless steel or aluminium with all air-flow apertures fitted with ‘honeycomb’ EMC filters and all panels fitted with EMC gaskets, it complies fully with the stringent EMC specifications of DEF-STAN 59-411, Land Class ‘A’. The bulkheads between internal and external areas within the unit are sealed ‘air-tight’ in-order that the unit can be operated in conjunction with Nuclear Biological and Chemical (NBC) filtration units. The refrigeration circuit is ‘hermetically’ sealed for ‘leak free’ reliability. Available in both 400Vac 3 Phase or 230Vac single phase.

As a modular, packaged solution CMCA's shelter and container integrated air-conditioning and climate control systems offer efficient integration and compact space envelopes whilst achieving maximum heating and cooling capacity. Designed to meet the most demanding technical requirements and built to the highest quality standards, CMCA's military air-conditioning and climate control solutions provide reliable heating and cooling capability in the most demanding environments on earth.

 

With a global customer base, CMCA's systems are proven in all environmental conditions, from snow storm to sand storm, providing mission critical Heating, Ventilation, Air-Conditiong & Cooling for both equipment and personnel. As a project driven organisation, systems are designed and built to customers exacting technical and commercial requirements to deliver the optimum HVAC solution, a COTS range consists of battlefield proven air-conditioners which can be adapted to meet specific requirements. 

Systems are tested to the most demanding of requirements, including climatic conditions from -46°C to +63°C and EMC performance to Def Stan 59 411 Land Class A, MIL STD 461 and TEMPEST, with low acoustic signatures through innovative acoustic, thermal and EMC attenuating enclosures. Various paint finishes are available including Infrared reflective (IRR) Matt paint and Chemical Agent Resistant Coating (CARC) Standard 80-208.

MPA-550

Military Packaged Air-conditioner

Cooling: 5.8 kW @ +35°C Ambient 

Cooling: 4.5 kW @ +55°C Ambient 

Heating: 4.0 W

Evaporator Airflow: 1,050m³/hr

Operating Conditions: -46°C to +55°C

Power Supply: 230/400Vac, 50Hz

Weight: 102kg

Length: 775mm

Width: 430mm

Height: 695mm

Designed to replace the UK MoD Type 57 ACU the “ruggedised” MPA-550 is currently in-service with military forces throughout the world supporting RADAR, TACAN and electronic warfare systems. The unit is mounted externally or internally to a shelter and provides both equipment and operator climate control. Designed around a compact and efficient space envelope the MPA-550 is sized so it can discretely mounted underneath a work surface, with the conditioned airflow exiting from the top of the unit, or alternatively, it can discharge the airflow at ceiling level via a suitable plenum. The unit provides a constant flow of filtered ‘fresh-air’ into the shelter which can be manually closed off if required when the shelter is unmanned, whereupon air is conditioned/cooled and recirculated.

 

Monitoring and display of internal shelter temperature, mode status and fault alarms, is by a separate control unit which also allows the
ACU to be operated in ‘AUTO’ mode via an electronic thermostat or ‘Heat’ or Cooling’ modes can be selected manually. The control unit
can be mounted in accordance with customer requirements. The unit is designed to operate in extreme environments as defined in
DEF STAN 00-35 climatic categories A1 to C2. It is constructed from lightweight aluminium and its refrigeration circuit is ‘hermetically’ sealed for ‘leak free’ reliability. Available in both 400Vac 3 Phase or 230Vac single phase.

MPA-900

Military Container air-conditioner

Designed specifically for military applications the MPA-900 is a ‘ruggedised’ air conditioning unit providing both equipment and operator climate control. It is mounted externally on military shelters transported by ‘high mobility’ vehicles across rough terrain. The unit provides a constant flow of filtered ‘fresh-air’ into the shelter. The conditioned airflow has both low and high speed operation along with two stages of cooling in-order to provide ‘close control’ around the selected set-point temperature. Refrigeration circuits are ‘hermetically’ sealed for ‘leak free’ reliability.

 

Monitoring and display of internal shelter temperature, mode status and fault alarms is by a separate control unit, which also allows the ACU to be operated in ‘AUTO’ mode via an electronic thermostat or manually in ’Heat’ or ’Cooling’ modes. The control unit can be mounted within a 19” rack system, or in accordance with customer requirements. Manufactured from lightweight aluminium, it complies with stringent EMC requirements and has been qualified to DEF STAN 59-41 Land Class A. All the airflow apertures are fitted with ‘honeycomb’ EMC filters and all panels have EMC gaskets fitted. The unit can be operated in extreme environments as defined in DEF STAN 00-35 climatic categories A1 to C2. Designed for 400Vac 3 Phase electrical supply, it is NATO codified.

The MPA-910 air conditioning unit has a ‘ruggedized’ design for Military applications and provides both equipment and user climate control within containerised shelters and on military vehicles, which traverse rough terrain. The unit is constructed from lightweight aluminium, is mounted externally to the shelter and provides a constant flow of filtered ‘fresh-air’ into the shelter. The conditioned airflow has both low and high speed operation along with two stages of cooling in-order to provide ‘close control’ around the selected set-point temperature.

 

The unit requires a remote Control Unit which displays the actual temperature as well as the operational mode status along with fault mode alarms. From the Control Unit the ACU can be operated in AUTO mode from the electronic thermostat or alternatively, MANUAL ‘Heat’ or Cooling’ modes can be selected. It is designed to operate in extreme environments as defined in DEF STAN 00-35 climatic categories A1 to C2. This unit is currently built to comply with the commercial EU EMC standard achieving TEMPEST qualification. It can also be supplied fitted with all relevant ‘honeycomb’ EMC filters and gaskets to meet DEF STAN 59-411 Land Class A. The refrigeration circuit is ‘hermetically’ sealed for ‘leak free’ reliability. Designed for 400Vac 3 Phase electrical supply, it is NATO codified.
